NiteHush Pro Review: Can a 500 mg Citrus-Flavonoid-and-Enzyme Chewable With Undisclosed Doses Do Anything About Snoring? (2026)
NiteHush Pro is a once-nightly chewable sold direct through the vendor's site with DigiStore24 checkout at $69 for one bottle, $59 per bottle for three, and $49 per bottle for six, with a 60-day money-back guarantee. The sales pitch is that snoring and sleep apnea come from 'respiratory nerves in the throat' damaged by phthalates, and that the chewable 'strengthens' those nerves. The Supplement Facts panel tells a plainer story: a single 500 mg proprietary blend of citrus hesperidin, ivy leaf extract, serratiopeptidase, liposomal quercetin, a broccoli extract standardized to 1% glucoraphanin, and naringin, sweetened with allulose, xylitol, and stevia. We read the text presentation, the label, the refund and shipping policies, and all twenty entries on the vendor's references page, then checked each ingredient against PubMed. Several of these compounds have small human trials for blood vessels, cough, allergy symptoms, or liver enzymes. None has a human trial for snoring, and none has been tested in obstructive sleep apnea. The 500 mg total is below the single-ingredient doses used in the trials that do exist, and no per-ingredient amount is disclosed.

At a glance
Best for
- Adults 40-65 whose snoring is mild, worse on the back or with a stuffy nose, and who have already been told they do not have sleep apnea
- People who prefer a chewable to capsules and will take one thing at bedtime every night
- Buyers who read the label rather than the sales page and understand they are getting a small citrus-flavonoid blend, not a nerve repair kit
- Anyone already using the things that actually reduce snoring, side-sleeping, weight loss, less alcohol at night, nasal strips or saline, who wants a low-risk add-on
- Buyers who can commit to the 3- or 6-bottle order so the refund window is not the limiting factor
Not for
- Anyone with loud snoring plus witnessed pauses in breathing, gasping, morning headaches, or daytime sleepiness: these are sleep apnea symptoms that need a sleep study, not a chewable
- Anyone with diagnosed obstructive sleep apnea who is thinking of using this instead of CPAP or an oral appliance
- People who want disclosed per-ingredient doses; the label gives one 500 mg total for six ingredients and no enzyme activity units
- Households with dogs: the chewable contains xylitol, which is toxic to dogs, and a sweet chewable left on a nightstand is a real hazard
- People on blood thinners or with a bleeding disorder: serratiopeptidase has fibrinolytic activity and the label carries no bleeding warning
- Anyone expecting the 'phthalates damaged your throat nerves' story to be a diagnosis rather than a sales angle

NiteHush Pro still worth it in 2026?
A pleasant, low-dose citrus-flavonoid chewable wrapped in a nerve-damage story the research does not support: a fair trial for mild, occasional snoring only after a doctor has ruled out sleep apnea
"My wife says the snoring is quieter on most nights, not gone. I sleep in a different position now too, so I honestly cannot tell which one did it."
"It tastes like a sour citrus gummy and it is one a night, so it is easy. The nerve-damage-from-plastics thing on the website is not something my ENT had ever heard of."
"I bought it hoping to skip the sleep study. Two months in, I did the sleep study anyway. Moderate apnea. Do the study first."
- Hesperidin, quercetin, ivy leaf, serratiopeptidase, and naringin each have at least one small human trial, but for endothelial function, upper-respiratory infections, cough, ENT swelling, or lipids, not for snoring or sleep apnea.
- The trials used 500 mg of hesperidin, 200 to 1,000 mg of quercetin, 30 mg of serrapeptase, or 450 mg of naringin per day; NiteHush Pro's entire six-ingredient blend is 500 mg, so no ingredient can be at its trial dose.
- No supplement has been shown to treat obstructive sleep apnea. Untreated moderate-to-severe apnea roughly triples the risk of fatal and non-fatal cardiovascular events in long-term follow-up; a sleep study, CPAP, or an oral appliance is the standard of care.
- 60-day money-back guarantee per the vendor's refund policy, counted from delivery; all bottles must be mailed back at your cost to Tallmadge, Ohio, and the vendor recommends 3 months of use before judging.
Best suited to adults with mild, positional or congestion-related snoring who have been screened for sleep apnea and want a one-a-night chewable to try alongside side-sleeping, weight management, and nasal care, bought as the 3- or 6-bottle pack so the guarantee window and the vendor's 3-month recommendation overlap.
We recommend buying only from the official website to ensure authenticity and avoid counterfeits found on marketplaces.

What is NiteHush Pro?
A one-a-night citrus-flavonoid chewable sold as 'respiratory nerve support' for snoring
NiteHush Pro is a 30-count chewable dietary supplement distributed by a company of the same name in Tallmadge, Ohio, and sold through DigiStore24. The Supplement Facts panel lists one 500 mg proprietary blend per chewable: citrus hesperidin 90%, ivy extract (Hedera helix leaf), serratiopeptidase, liposomal quercetin 70%, a broccoli-derived extract at 1% glucoraphanin, and naringin 99% from Citrus maxima fruit. The other ingredients are allulose, xylitol, natural flavors, magnesium stearate, silicon dioxide, and steviol glycosides under the OnoSweet trademark. The label says the product is made in the USA using foreign and US ingredients in an FDA-registered, GMP facility, and it lists no amount for any single ingredient and no activity units for the enzyme.
The vendor's text presentation makes one central claim: 'special compounds' in the chewable 'support the respiratory nerves in the throat', which 'maintain a clear airflow during sleep'; exposure to phthalates 'can damage these nerves, leading to snoring and sleep apnea'; and the formula 'helps strengthen these nerves, promoting peaceful, snore-free nights'. The three benefit icons are restful nights, energy and focus, and sinus support. The label's own front panel is more modest: 'Restful Nights, Relax & Recharge, Sinus Support', each with an asterisk to the FDA disclaimer. The page names the six ingredients but gives no per-ingredient doses and no explanation of how a citrus flavonoid or a bacterial enzyme would rebuild a nerve.
The references page has twenty entries. Three are real papers on nerve and muscle changes in the upper airway of snorers and apnea patients, which is genuine sleep-medicine literature; they describe injury caused by years of vibration and airway collapse, and none of them tests anything that reverses it. The rest are pharmacology reviews of hesperidin and naringenin, two reviews of phthalate toxicity, a zebrafish study, two mouse studies of quercetin liposomes in lung injury, a COPD network-pharmacology paper, a long-COVID review, a post-COVID fatigue trial of an enzyme-plus-probiotic product, and two press articles. Nothing on the page connects any NiteHush Pro ingredient to snoring, airway muscle tone, or apnea in a human being.
Where does that leave someone comparing options? If snoring is the complaint, the first step is a screening for obstructive sleep apnea, because loud snoring is its most common symptom and no chewable addresses it. If the goal is simply better sleep and calmer evenings, YU Sleep is our current pick in this category, with GABA, L-theanine, 5-HTP, and magnesium at a similar price; we compare the two at /compare/nitehush-pro-vs-yu-sleep.
How it works
How NiteHush Pro is supposed to work, and what the research actually supports
Step 1
The 'Respiratory Nerve' Story: The vendor's premise is that phthalates from plastics damage nerves in the throat, and that these damaged nerves cause snoring and sleep apnea. The real literature is narrower. Hypoglossal nerve conduction is reduced in apnea patients compared with matched controls in a 40-person study, and a 2012 review concludes that sensorimotor injury in the upper airway is real but that 'the extent to which the alterations contribute to upper airway muscle function, and thus OSA disease progression, remains uncertain'. That injury is attributed to years of snoring vibration and intermittent low oxygen, not to phthalates. A PubMed search for phthalates and snoring, or phthalates and sleep apnea, returns nothing.
Step 2
Blood-Vessel Flavonoids: Hesperidin is the best-studied ingredient. In a randomized, placebo-controlled crossover trial in 24 adults with metabolic syndrome, 500 mg per day for 3 weeks raised brachial flow-mediated dilation from 7.78% to 10.26% and lowered high-sensitivity CRP, serum amyloid A, and E-selectin. A 4-week crossover in healthy volunteers found a hesperidin drink lowered diastolic blood pressure like orange juice did. Neither trial measured sleep or breathing, and 500 mg is the whole NiteHush Pro blend.
Step 3
Sinus and Allergy Angle: Quercetin is the ingredient closest to the 'sinus support' claim. In a 66-person randomized, placebo-controlled study, 200 mg per day of a bioavailable quercetin formulation for 4 weeks improved several hay-fever quality-of-life scores, including a sleep-disturbance subscale. In a 1,002-person community trial, 500 or 1,000 mg per day for 12 weeks did not reduce upper-respiratory infections overall; only a subgroup of fit adults over 40 on 1,000 mg had fewer sick days. Congestion-related snoring is a real thing, but NiteHush Pro does not say how much quercetin it contains, and 200 mg would be 40% of the blend.
Step 4
Mucus and Swelling: Serratiopeptidase is a protease from Serratia bacteria marketed for inflammation and mucus. An open-label study of 15 patients with chronic airway disease on 30 mg per day for 4 weeks found less sputum, lower viscosity, and fewer sputum neutrophils versus 14 untreated controls, and a 1990 double-blind trial in 193 ENT patients reported faster symptom regression over 7-8 days. A 2013 systematic review concluded the existing evidence is insufficient to support its use. Pharmaceutical serrapeptase is enteric-coated because the enzyme is a protein that stomach acid degrades; a chewable that sits in saliva and stomach acid gives it no such protection, and the label lists no activity units.
Step 5
Cough Herb: Ivy leaf extract is a European over-the-counter cough remedy. The 2021 updated systematic review found six randomized trials, all reporting faster cough relief in acute bronchitis or colds, and rated the clinical significance 'minimal' with high risk of bias. No study looks at snoring or nighttime airway tone.
Step 6
Broccoli and Grapefruit Compounds: Glucoraphanin converts to sulforaphane, which induces detoxification enzymes; a broccoli sprout beverage delivering 600 micromoles of glucoraphanin a day, roughly 260 mg, raised excretion of airborne pollutants in a Chinese trial, and a broccoli sprout extract lowered liver enzymes in 24 Japanese men over 2 months. NiteHush Pro's extract is standardized to 1% glucoraphanin. Naringin at 450 mg per day for 90 days reduced BMI and lipids in a 28-patient trial. The vendor cites an exploratory glucoraphanin-and-sleep study in a journal that is not indexed in PubMed; we could not verify it.
Step 7
What Actually Treats Apnea: The American Academy of Sleep Medicine's 2019 guideline recommends positive airway pressure for adults with obstructive sleep apnea, and its 2015 guideline recommends custom oral appliances for snoring and for apnea patients who cannot tolerate CPAP. In 2024, two 52-week randomized trials in adults with obesity and moderate-to-severe apnea found tirzepatide cut the apnea-hypopnea index by 25 to 29 events per hour versus about 5 on placebo, and it became the first FDA-approved drug for the condition. None of these pathways runs through a citrus chewable.

Ingredients
Citrus Hesperidin (90%)
Benefits:
The best-studied ingredient in the formula, and the first on the label. In a randomized, placebo-controlled, double-blind crossover trial in 24 adults with metabolic syndrome, 500 mg of hesperidin once daily for 3 weeks raised brachial artery flow-mediated dilation from 7.78% to 10.26% and lowered high-sensitivity CRP, serum amyloid A, and E-selectin. A hesperidin drink also lowered diastolic blood pressure like orange juice in a 4-week crossover in healthy volunteers. These are blood-vessel and inflammation outcomes; a PubMed search for hesperidin and sleep or snoring trials returns nothing. The 500 mg trial dose is the size of NiteHush Pro's entire six-ingredient blend. Individual dose not disclosed.
Ivy Extract (Hedera helix, leaf)
Benefits:
A European over-the-counter cough remedy. A 2021 updated systematic review found six randomized trials, one controlled trial, and four observational studies in cough due to upper respiratory infections and bronchitis; three of the trials reported a faster drop in cough severity or frequency, the clinical significance was judged minimal, and the quality of reporting was low with high risk of bias. No study examines ivy leaf for snoring, nighttime airway tone, or sleep. Ivy is a latex-fruit cross-reactor in some allergic individuals, and the label carries no allergen statement. Dose not disclosed.
Serratiopeptidase
Benefits:
A protease enzyme from Serratia bacteria marketed for swelling and mucus. A 2013 systematic review concluded the existing evidence is insufficient to support its clinical use. The two positive studies are an open-label trial in which 30 mg per day for 4 weeks reduced sputum weight, viscosity, and neutrophil counts in 15 patients with chronic airway disease versus 14 untreated controls, and a 1990 double-blind trial in 193 ear, nose, and throat patients that reported faster symptom regression over 7-8 days. Pharmaceutical serrapeptase is enteric-coated because the enzyme is a protein that stomach acid degrades; a chewable provides no such protection. It has fibrinolytic activity and is routinely cautioned against with anticoagulants and before surgery, a warning the label omits. No activity units and no dose disclosed.
Liposomal Quercetin (70%)
Benefits:
The ingredient closest to the 'sinus support' claim. In a 66-person randomized, placebo-controlled, double-blind study, 200 mg per day of a bioavailable quercetin formulation for 4 weeks improved several hay-fever quality-of-life scores, including a sleep-disturbance subscale. In a 1,002-person community trial, 500 or 1,000 mg per day for 12 weeks did not reduce upper respiratory infections overall; only a subgroup of fit adults over 40 on 1,000 mg had 36% lower illness severity and 31% fewer sick days. Congestion-related snoring is real, but 200 mg would be 40% of NiteHush Pro's whole blend, and the liposomal claim cannot be checked without a stated amount. Dose not disclosed.
Glucoraphanin (broccoli-derived extract, 1%)
Benefits:
The glucosinolate precursor of sulforaphane, which induces detoxification enzymes. A sulforaphane-rich broccoli sprout extract lowered serum ALT and gamma-GTP over 2 months in 24 Japanese men with fatty liver versus 28 on placebo, and a broccoli sprout beverage supplying 600 micromoles of glucoraphanin a day, roughly 260 mg, increased urinary excretion of airborne pollutants in a randomized trial in China. The vendor's own citation for glucoraphanin and sleep quality is an exploratory study in a journal not indexed in PubMed, which we could not verify. The label's extract is standardized to only 1% glucoraphanin, so even if the entire 500 mg blend were this extract it would deliver 5 mg. Dose not disclosed.
Naringin (99%, Citrus maxima fruit)
Benefits:
The bitter flavonoid of grapefruit and pomelo. In a double-blind randomized trial of 28 adults with dyslipidemia, 450 mg per day for 90 days reduced BMI (30.6 vs 33.3 kg/m2), improved plasma lipids, and raised adiponectin versus placebo. Naringin is considered the major grapefruit-juice component that inhibits intestinal drug uptake, although a 10-volunteer crossover study found high-dose short-term naringin did not alter absorption of the test drug talinolol; anyone on medication with a grapefruit warning should still check with a pharmacist. There is no human study of naringin for snoring, sleep, or upper-airway function. Dose not disclosed.
Safety
Safety profile and what to expect
NiteHush Pro combines two citrus flavonoids, a broccoli-derived extract, an herbal cough extract, a bacterial protease, and a liposomal form of quercetin at a combined 500 mg per chewable, in a base of allulose, xylitol, and stevia. The label says adults take one chewable in the evening before bed, not to exceed the recommended dose, and that pregnant or nursing women, children under 18, and anyone with a known medical condition should consult a physician. It carries no allergen statement and no bleeding or drug-interaction warning. The label claims manufacture in the USA from foreign and US ingredients in an FDA-registered, GMP facility; an FDA-registered facility is a filing, not an inspection or approval.
The low total dose is the main reason side effects are uncommon, but three ingredients deserve attention. Serratiopeptidase has fibrinolytic activity, which is the reason it is marketed for clots and swelling, and it is routinely listed as a caution alongside warfarin and other anticoagulants. Naringin and hesperidin are grapefruit and orange flavonoids; naringin is the compound most often blamed for grapefruit-juice drug interactions, although a 10-volunteer study found high-dose naringin did not change absorption of the test drug talinolol. Xylitol is harmless to people at this amount but is toxic to dogs even in small quantities, and a sweet chewable is exactly the kind of thing a dog will find on a nightstand. Anyone on anticoagulants or narrow-window medications should ask a pharmacist before adding this.
Possible Side Effects
- ⚠Mild stomach upset, loose stools, or gas from the sugar alcohol and allulose base, more likely if taken on an empty stomach
- ⚠Sour or bitter aftertaste from the citrus flavonoids; some users prefer to swallow the chewable with water as the label allows
- ⚠Mild headache or flushing in the first week, reported occasionally with flavonoid-rich supplements
- ⚠No sedative effect; anyone expecting to feel drowsy will not, and the formula contains nothing that causes grogginess
Warnings
- ✗Do not use as a substitute for evaluation of suspected sleep apnea; loud snoring with pauses, gasping, morning headaches, or daytime sleepiness needs a sleep study
- ✗Do not stop CPAP or an oral appliance to try a supplement; untreated apnea carries cardiovascular risk
- ✗Serratiopeptidase has fibrinolytic activity; avoid if you take warfarin, DOACs, or antiplatelet drugs, or have a bleeding disorder, unless your doctor clears it, and stop two weeks before surgery
- ✗Citrus flavonoids (naringin, hesperidin) belong to the grapefruit family of compounds; check with a pharmacist if you take drugs with a grapefruit warning
- ✗Contains xylitol, which is toxic to dogs; store out of reach of pets
- ✗No allergen statement on the label; contact the vendor if you have a citrus or latex-fruit allergy, since ivy leaf can cross-react in some people
- ✗Not for anyone under 18 or for pregnant or nursing women, per the label; consult a physician if you take medication or have a medical condition

How to take NiteHush Pro for best results
Timing
About 30 to 60 minutes before bed with a little water is the simplest routine. The vendor's refund policy advises using NiteHush Pro for at least 3 months before judging it, which conflicts with a 60-day refund window that starts on delivery.
Directions
- Take one chewable in the evening before bed, per the label; each bottle has 30 chewables, a 30-day supply
- Chew it slowly or swallow it with a glass of water; the label allows either, and the vendor's FAQ says the same
- Do not exceed one chewable a day; the label cautions against exceeding the recommended dose
Pro Tips
- 💡Before you start: if anyone has heard you stop breathing or gasp at night, or you wake unrefreshed, book a sleep study first. A home sleep test is inexpensive and a chewable cannot replace it.
- 💡Weeks 1-2: Record your snoring with a free phone app for a few nights before and after starting; a partner's impression is unreliable and this is the only way to tell a change from wishful thinking.
- 💡Weeks 3-6: This is when the hesperidin and quercetin trials measured their vascular and allergy outcomes, so if congestion-related snoring is going to ease, this is the window.
- 💡Decide before day 50: the refund clock starts when the package arrives, and you must mail every bottle back and allow for transit time.
- 💡Stack the things with real evidence: sleep on your side, cut alcohol within three hours of bed, treat nasal congestion, and lose weight if you carry it around the neck. These do more for snoring than any capsule or chewable.
- 💡Keep the bottle away from dogs; the xylitol in a sweet chewable is a genuine veterinary emergency.
Note: Give NiteHush Pro a full 6-8 weeks, but set a calendar reminder. The vendor recommends 3 months; the guarantee gives you 2. Buy the 3-bottle pack if you want the evaluation and the refund window to line up.
What users report after taking NiteHush Pro
Note: Individual results vary with weight, sleep position, nasal congestion, alcohol, and medications. Benefits are most often reported by people with mild, congestion-related snoring who also changed how they sleep.

Pros & Cons
✓Pros
- +Every ingredient has at least one human trial, which is more than most snoring supplements can say, even if none of the trials is about snoring
- +Hesperidin and quercetin have randomized, placebo-controlled data for blood-vessel function and allergy symptoms at 200-500 mg per day
- +One chewable at bedtime is a routine almost anyone will keep, and the label allows swallowing it with water for people who dislike the taste
- +No melatonin, no sedatives, no stimulants, no habit-forming ingredients; nothing in it causes grogginess
- +Full ingredient list printed on the label with a physical distributor address in Tallmadge, Ohio
- +6-bottle price of $49 is in line with YU Sleep and other DigiStore24 sleep products at the same tier
- +DigiStore24 checkout with a published refund policy and an order self-service portal, and the vendor states there is no autoship
✗Cons
- -500 mg total for six ingredients means no single ingredient can be at the 200-1,000 mg per day the human trials used; the enzyme has no activity units at all
- -The central claim, that phthalates damage 'respiratory nerves' and the chewable strengthens them, has no support on the vendor's own references page or anywhere on PubMed
- -The sales page names sleep apnea, a medical diagnosis, as something the product addresses; no supplement treats obstructive sleep apnea and the label itself makes no such claim
- -Broccoli extract standardized to only 1% glucoraphanin; even if it were the whole blend, that is 5 mg against the 260 mg used in the detoxification trial
- -Serratiopeptidase is a protein enzyme that pharmaceutical products enteric-coat to survive the stomach; a chewable offers no protection, and it carries a bleeding-risk caution the label omits
- -Xylitol in a sweet nightstand chewable is a hazard for households with dogs, with no warning on the label
- -60-day guarantee is shorter than the 3 months the vendor recommends, and you must mail every bottle back at your cost
- -Single bottle is $69; the advertised $49 price requires a $294 six-bottle order, and the post-purchase upsell pages offer additional bottles at $29 each, which tells you what the product actually costs to sell
- -The 'regular' $99 price, the '17,458 reviews', the '97% of customers order 6 bottles', and the two bonus ebooks with '$55' and '$54' retail values cannot be verified anywhere outside the sales page; the page shows free shipping on the 6-bottle order only while the shipping policy promises it on every US order
Evidence
Hesperidin: 500 mg once daily for 3 weeks increased brachial artery flow-mediated dilation (10.26% vs 7.78% on placebo) and reduced high-sensitivity CRP, serum amyloid A, and soluble E-selectin in a randomized, placebo-controlled, double-blind crossover trial in 24 adults with metabolic syndrome (Rizza et al., Journal of Clinical Endocrinology & Metabolism, 2011); a hesperidin-fortified control drink lowered diastolic blood pressure like orange juice over 4 weeks in a randomized crossover in healthy volunteers (Morand et al., American Journal of Clinical Nutrition, 2011); 8 weeks of flavanone-rich orange juice improved global cognitive function in healthy older adults (Kean et al., American Journal of Clinical Nutrition, 2015); no trial of hesperidin for snoring or sleep exists on PubMed
Ivy leaf (Hedera helix): an updated systematic review identified 6 randomized trials, 1 controlled trial, and 4 observational studies in cough due to upper respiratory infection or bronchitis; three RCTs reported faster reduction in cough severity or frequency, the clinical significance was judged minimal, reporting quality was low, and risk of bias was high (Sierocinski et al., European Journal of Clinical Pharmacology, 2021)
Serratiopeptidase: a systematic review concluded the existing scientific evidence is insufficient to support its use in clinical practice (Bhagat, Agarwal & Roy, International Journal of Surgery, 2013); in an open-label study, 30 mg per day for 4 weeks reduced morning sputum weight, viscosity, elasticity, and sputum neutrophil counts in 15 patients with chronic airway disease versus 14 untreated controls (Nakamura et al., Respirology, 2003); a multicentre double-blind trial in 193 patients with acute or chronic ear, nose, or throat inflammation reported faster symptom regression over 7-8 days of two tablets three times daily (Mazzone et al., Journal of International Medical Research, 1990)
Quercetin: in a randomized, double-blind, placebo-controlled community trial of 1,002 adults, 500 or 1,000 mg per day for 12 weeks did not reduce upper respiratory tract infection outcomes overall; in a subgroup of 325 fit adults aged 40 and older, the 1,000 mg group had 36% lower URTI severity and 31% fewer sick days (Heinz et al., Pharmacological Research, 2010); 200 mg per day of a bioavailable quercetin formulation for 4 weeks improved Japanese Rhino-conjunctivitis Quality of Life Questionnaire scores including sleep disturbance in a 66-person randomized, placebo-controlled study of pollinosis (European Review for Medical and Pharmacological Sciences, 2022)
Glucoraphanin / sulforaphane: capsules of a sulforaphane-rich broccoli sprout extract for 2 months lowered serum ALT and gamma-GTP in 24 Japanese men with fatty liver versus 28 on placebo (Kikuchi et al., World Journal of Gastroenterology, 2015); a broccoli sprout beverage supplying 600 micromoles of glucoraphanin and 40 micromoles of sulforaphane daily increased urinary excretion of airborne pollutants in a randomized trial in China (Egner et al., Cancer Prevention Research, 2014); the vendor's citation for glucoraphanin and sleep quality (Kikuchi et al., Journal of Functional Foods, 2021) is described as exploratory and is in a journal not indexed in PubMed, so we could not verify it
Naringin: 450 mg per day for 90 days reduced BMI (30.6 vs 33.3 kg/m2), plasma lipids, and increased adiponectin versus placebo in a double-blind randomized trial of 28 adults with dyslipidemia (International Journal for Vitamin and Nutrition Research, 2022); high-dose short-term naringin did not alter the pharmacokinetics of talinolol in a 10-volunteer crossover study, despite naringin being considered the major grapefruit-juice component that inhibits intestinal drug uptake (European Journal of Pharmaceutical Sciences, 2015)
Upper airway nerve injury, the vendor's premise: hypoglossal nerve compound muscle action potential amplitudes were significantly reduced in 20 obstructive sleep apnea patients compared with 20 age-matched controls (Ramchandren et al., Muscle & Nerve, 2010); a review of human data concludes that upper airway sensorimotor injury occurs in OSA, attributed to intermittent hypoxia and mechanical strain from snoring, but that the extent to which it contributes to muscle dysfunction and disease progression remains uncertain (Saboisky et al., Frontiers in Neurology, 2012); neither paper tests any intervention that reverses the injury, and PubMed searches for phthalates with snoring or with sleep apnea return no results
Cardiovascular risk of untreated apnea: in a 10-year observational study of 1,651 men, those with untreated severe obstructive sleep apnoea had 1.06 fatal and 2.13 non-fatal cardiovascular events per 100 person-years versus 0.3 and 0.45 in healthy controls and 0.35 and 0.64 in CPAP-treated patients; adjusted odds ratios were 2.87 for fatal and 3.17 for non-fatal events (Marin et al., Lancet, 2005)
Standard of care: the American Academy of Sleep Medicine clinical practice guideline recommends positive airway pressure for adults with obstructive sleep apnea (Patil et al., Journal of Clinical Sleep Medicine, 2019), and the joint AASM/AADSM guideline recommends custom, titratable oral appliances for adult snoring and for OSA patients intolerant of CPAP (Ramar et al., Journal of Clinical Sleep Medicine, 2015); in two 52-week randomized trials in adults with obesity and moderate-to-severe OSA, tirzepatide reduced the apnea-hypopnea index by 25.3 and 29.3 events per hour versus 5.3 and 5.5 on placebo (Malhotra et al., New England Journal of Medicine, 2024)
Post-COVID fatigue trial on the vendor's references page: a systemic enzyme complex plus a probiotic complex resolved fatigue in 91% versus 15% on placebo at day 14 in 200 patients (Rathi et al., Medicines, 2021); the product tested is not NiteHush Pro, the enzyme complex is not identified as serratiopeptidase alone, and the outcome is not snoring
The vendor's 'respiratory nerve' and phthalate claims are supported on its references page only by general phthalate toxicity reviews, a zebrafish neurodevelopment study, and two press articles about nerve and muscle damage in the palates of snorers; no study on the page links any NiteHush Pro ingredient to snoring, airway muscle tone, or apnea severity in humans
Who is it for?
Perfect for:
- ✓Adults 40-65 with mild, positional or congestion-related snoring who have been screened for obstructive sleep apnea
- ✓People who want a one-a-night chewable rather than capsules and will keep the routine
- ✓Those who accept that a 500 mg flavonoid blend is a mild sinus and inflammation supplement, not a snoring cure
- ✓People already working on the things that reduce snoring, side-sleeping, weight, alcohol timing, and nasal care, who want a low-risk add-on to discuss with a doctor
- ✓Adults who are not on anticoagulants or antiplatelet drugs, given the serratiopeptidase
- ✓Households without dogs, or buyers who will store a xylitol chewable well out of a pet's reach

"I read the label before buying and knew it was basically citrus flavonoids and quercetin, so I was not expecting a miracle. My hay fever snoring is noticeably better after six weeks and my husband has stopped poking me. I will keep taking it through pollen season. Do not expect anything for energy; there is nothing in it for that."
Miguel R.
San Antonio, TX
"The website goes on about plastics damaging nerves in your throat. My ENT laughed at that. I judged it on results: a small improvement in how stuffy I feel at night, no real change in snoring according to the recording app. It is fine as a mild sinus chewable. It is not a snoring cure."

"The bonus ebooks are throwaway and the '97% order six bottles' line is silly, but the chewables have been good to me. Less congestion by week five, no stomach trouble, and I sleep through more nights. One warning: keep it off the nightstand if you have a dog. Ours got into the bottle and the vet visit cost more than the six-pack."

🏆Conclusion
Editorial Verdict
NiteHush Pro is a small citrus-flavonoid chewable sold with a large neurological story. The ingredient choices are not absurd: hesperidin, quercetin, ivy leaf, serratiopeptidase, and naringin all have small human trials for inflammation, vascular function, cough, or allergy symptoms, and nothing in the formula is dangerous at 500 mg for a healthy adult. The problems are the claims and the numbers. No ingredient has ever been tested for snoring or apnea in people; the 'phthalates damaged your throat nerves' mechanism does not appear in the sleep-medicine literature the vendor itself cites; the 500 mg blend cannot deliver the 500 mg of hesperidin, 200 mg of quercetin, 30 mg of serrapeptase, or 450 mg of naringin the trials used; and the enzyme is delivered in a chewable with no acid protection and no activity units. Add a sales page that names sleep apnea, a diagnosis that carries real cardiovascular risk when untreated, plus a 60-day guarantee that expires before the vendor's own 3-month recommendation, and the risk of buying this instead of getting a sleep study is the thing to worry about. If your snoring is mild and positional, a doctor has ruled out apnea, you have no dogs in the bedroom and take no blood thinners, and you buy the 3- or 6-bottle pack with a calendar reminder, NiteHush Pro is a low-risk trial with the guarantee as a safety net. If you want a sleep supplement with better-documented ingredients at the same price, YU Sleep remains the stronger buy in this category, and a $10 box of nasal strips remains the better buy for congestion-related snoring.
Snoring supplements split into two camps. One camp is honest about what a capsule can do: reduce congestion a little, calm inflammation a little, and help you sleep alongside the changes that actually matter. The other camp invents a mechanism, names a disease, and sells the story. NiteHush Pro's label sits in the first camp, with restrained 'Restful Nights, Relax & Recharge, Sinus Support' claims and a sensible ingredient list. Its sales page sits firmly in the second, with respiratory nerves, phthalates, and sleep apnea.
What we cannot do is tell you how much of anything you are getting. The label discloses the 500 mg total but not the parts, the enzyme has no units, the broccoli extract is a 1% standardization, and the reference list, to the vendor's discredit, mixes real sleep-medicine papers about nerve injury with mouse lung studies and press releases to build a bridge the papers do not build. The nerve-damage narrative is the page's engine, and it is not something a sleep physician would recognize as the cause of snoring.
Is it worth trying? For an adult with mild, doctor-screened snoring who wants a one-a-night chewable and buys the 3- or 6-bottle pack, it is a reasonable low-risk trial with a 60-day exit. For anyone with apnea symptoms, the answer is a sleep study, not a chewable, and for anyone who mainly wants to fall asleep faster and sleep more deeply, YU Sleep's GABA, L-theanine, 5-HTP, and magnesium formula is the stronger option, with Sleep Lean worth a look for people whose weight is part of the picture. Both are covered on this site.

- Six ingredients in a 500 mg proprietary blend; per-ingredient doses and enzyme units not disclosed

FAQ
Where can I buy NiteHush Pro?
NiteHush Pro is sold only through the vendor's site, where checkout runs through DigiStore24; some affiliate links route through ClickBank, but the product and the checkout are the same. It is not sold in stores, and listings on Amazon, Walmart Marketplace, or eBay are not from the manufacturer and are not covered by the guarantee. Buying direct is the only way to get the 3- and 6-bottle pricing, the two bonus ebooks, and the 60-day money-back guarantee. The label lists the distributor as Nitehush Pro, Tallmadge, OH 44278, with product support at contact@nitehushpro-product.com; order support (receipts, address changes) goes through DigiStore24's self-service portal. You can reach the vendor's order page through the links on this review.
How much does NiteHush Pro cost?
At the time of this review, the vendor's site lists a single bottle (30 chewables, a 30-day supply) at $69. The 3-bottle package is $59 per bottle ($177 total) and the 6-bottle package is $49 per bottle ($294 total). The sales page shows free shipping and two bonus ebooks on the 6-bottle order; the vendor's shipping policy separately lists US shipping as free on every order with 5-7 working days transit, and $15.95 per order to Canada, the UK, Ireland, Australia, and New Zealand with 10-15 working days. The discounts are framed against a $99-per-bottle 'regular' price that, as far as we can tell, has never been charged; the post-purchase upsell pages offer extra bottles at $29 each. Prices can change, so check the vendor's site before ordering.
Is NiteHush Pro legit or a scam?
NiteHush Pro is a real product with a printed Supplement Facts label, a physical distributor and return address in Tallmadge, Ohio, and checkout through DigiStore24, an established payment processor with a published refund process. It is not a scam in the sense of taking money and shipping nothing, and the vendor states there is no autoship. It does have real problems: the doses are hidden in a 500 mg proprietary blend, the enzyme has no activity units, the sales page names sleep apnea and a phthalate nerve-damage mechanism that neither the label nor any study supports, the 'clinically researched ingredients' line on the bottle refers to trials that were never about snoring, and the '17,458 reviews' and '97% order six bottles' figures cannot be verified anywhere outside the sales page. Treat it as a legitimate but low-dose supplement sold with an exaggerated, medically misleading pitch.
Is there a NiteHush Pro discount or coupon code?
NiteHush Pro does not use coupon codes at checkout. The only discounts are the package prices on the vendor's site: $69 for one bottle, $59 per bottle for three, and $49 per bottle for six, with free shipping and two bonus digital guides advertised on the 6-bottle order. The vendor describes the 6-bottle price as $300 off, which is measured against a $99 'regular' price nobody appears to pay. Sites advertising NiteHush Pro coupon codes or a 180-day guarantee are affiliate pages; the vendor's refund policy says 60 days.
Does NiteHush Pro treat sleep apnea?
No, and no supplement does. Obstructive sleep apnea is a medical diagnosis made with a sleep study, and the standard treatments are positive airway pressure (CPAP), a custom oral appliance for milder cases or CPAP-intolerant patients, weight loss, and, since 2024, tirzepatide for adults with obesity. In a long-term study of over 1,600 men, untreated severe apnea carried about three times the risk of fatal and non-fatal cardiovascular events compared with healthy controls, while CPAP-treated patients had risks close to normal. The NiteHush Pro sales page uses the phrase 'snoring and sleep apnea' in describing what phthalate-damaged nerves supposedly cause; the label itself makes no apnea claim, and none of the six ingredients has been tested in apnea patients. If you snore loudly and anyone has seen you stop breathing, gasp, or you wake with headaches or fall asleep during the day, get a sleep study before spending money on any chewable.
What are the ingredients in NiteHush Pro?
The Supplement Facts label lists a 500 mg proprietary blend per chewable: citrus hesperidin 90%, ivy extract (Hedera helix leaf), serratiopeptidase, liposomal quercetin 70%, a broccoli-derived extract at 1% glucoraphanin, and naringin 99% (Citrus maxima fruit). Other ingredients are allulose, xylitol, natural flavors, magnesium stearate, silicon dioxide, and steviol glycosides (OnoSweet). Per-ingredient amounts are not disclosed, the enzyme has no activity units, and there is no allergen statement. The sales page names the same six actives, so the label and the page agree on what is in it, if not on what it does.
How long before I notice results?
Do not expect anything the first night; there is no sedative or decongestant in it. In the human trials behind the best-supported ingredients, hesperidin and quercetin, outcomes were measured at 3 to 4 weeks and beyond, and those outcomes were blood-vessel function and hay-fever symptoms, not snoring. People who report a change with NiteHush Pro usually describe less bedtime congestion between weeks 3 and 6, and 'quieter' snoring from a partner in the same window, often alongside side-sleeping or less evening alcohol. The vendor itself recommends 3 months of use before judging. That is why the 60-day refund window is tight: record your snoring with a phone app before you start, decide by day 50, and buy the 3-bottle pack if you want the evaluation and the guarantee to line up.
Is NiteHush Pro safe with medications?
Ask your pharmacist first. The total amount is small, which keeps the risk low, but two ingredients matter. Serratiopeptidase has fibrinolytic activity and is routinely cautioned against alongside warfarin, DOACs, and antiplatelet drugs, and before surgery; the label carries no such warning. Naringin and hesperidin are the flavonoids found in grapefruit and orange, and naringin is the compound most often implicated in grapefruit-juice drug interactions, although a 10-person study found high-dose naringin did not alter absorption of the test drug. The label also warns against use under 18 or during pregnancy or nursing and advises anyone with a medical condition to consult a physician. Separately, the chewable contains xylitol, which is toxic to dogs; keep it away from pets.
NiteHush Pro vs YU Sleep: which is better?
They are built for different complaints. NiteHush Pro is a one-a-night 500 mg citrus-flavonoid-and-enzyme chewable aimed at snoring and sinus congestion, with no per-ingredient doses and no ingredient tested for snoring. YU Sleep is a two-capsule melatonin-free formula of GABA, L-theanine, 5-HTP, magnesium, and tart cherry aimed at falling asleep faster and sleeping more deeply, also with a 60-day guarantee and a similar $49-per-bottle six-pack price. If your problem is that you cannot fall asleep or stay asleep, YU Sleep is the more relevant and better-documented product, and it is our pick in this category; read the full review at /reviews/yu-sleep. If your only complaint is mild congestion-related snoring and apnea has been ruled out, NiteHush Pro is the one that at least targets it. The full side-by-side is at /compare/nitehush-pro-vs-yu-sleep.
What if NiteHush Pro doesn't work for me?
Use the guarantee, and use it on time. Email the vendor with 'Refund Request' in the subject before day 60 from delivery, keep the packing slip, and mail every bottle, empty or full, with a note carrying your name, email, and order ID to 285 Northeast Ave, Tallmadge, OH 44278, with tracking so you have proof of receipt. Return shipping is at your cost, and the vendor says refunds are processed within 5-10 days of receiving the package. If you have an order question rather than a product question, DigiStore24's customer self-service portal handles receipts and order lookups, and DigiStore24 has its own buyer-protection process if the vendor does not respond. And if the reason it did not work is that your snoring is actually apnea, the refund is the least important next step; the sleep study is.
