Quick Verdict
Choose Fast Lean Pro if you want:
- ✓Adults 35-65 who already follow a calorie-controlled eating plan and want a low-dose daily fiber plus B vitamins in one scoop
- ✓People who cannot tolerate caffeine or stimulant fat burners and want something they can mix into morning coffee or tea
- ✓Anyone who has tried intermittent fasting, found it unsustainable, and wants a modest satiety aid, not a substitute
May not be ideal for:
Anyone expecting to 'burn fat no matter what and when you eat'; no ingredient in the jar does that, and the vendor's own references do not show it
Choose OrexiBurn if you want:
- ✓Adults who have already fixed diet and step count and want a stimulant-free capsule as a small addition, not a substitute
- ✓People who refuse proprietary blends and want every milligram printed on the panel, even when the milligrams are small
- ✓Anyone sensitive to caffeine, yohimbine or synephrine who wants a fat-burner-shaped product with none of those in it
May not be ideal for:
Anyone expecting double-digit weight loss; no capsule does that, and the only interventions that do in trials are GLP-1 drugs and bariatric surgery

Pros & Cons
Fast Lean Pro
Pros
- ✓Fibersol-2 and acacia gum both have randomized, placebo-controlled human trials for satiety and body fat, which is more than most 'fasting' supplements can say
- ✓Stimulant-free: no caffeine, green tea extract, synephrine, or yohimbine, so no jitters, no insomnia, and no interaction with blood pressure medication
- ✓Tasteless powder that dissolves in water, tea, or coffee; the easiest daily format in the category and a realistic habit
- ✓180-day money-back guarantee, three times longer than the 60 days most DigiStore24 supplements offer and long enough to cover the vendor's own 3-month recommendation
- ✓Vitamin and mineral doses are conservative and within safe ranges; nothing in the jar is likely to hurt a healthy adult
Cons
- ✗The vendor's site never shows a Supplement Facts panel; the only label data available comes from an independent transcription of the jar
- ✗The sales page names six ingredients and its own FAQ says 'eleven'; about half the 50 references concern calcium, iron, potassium, sodium, and vitamin D, none of which are among the named ingredients
- ✗1.7 g total for two fibers and a spermidine extract; the satiety trial needed 10 g of Fibersol-2 in one sitting, the visceral fat trials 15-27 g a day, and the gum arabic body-fat trial 30 g a day
- ✗The 'fasting switch', 'trick your brain into thinking you are fasting', and 'burn fat no matter what and when you eat' claims have no human study behind them; the autophagy citations are yeast, cell, and mouse papers
OrexiBurn
Pros
- ✓Every ingredient dose is printed on the Supplement Facts panel; no proprietary blend, which is rare in this category
- ✓Stimulant-free: no caffeine, synephrine, yohimbine or green tea extract, so no jitters and no sleep disruption
- ✓One capsule a day is the simplest protocol in the category and the easiest to actually keep
- ✓Ecklonia cava, L-arginine and curcumin each have real randomised human trials for body composition or metabolic markers, even if not at these doses
- ✓Free US shipping and a published shipping table with named rates and transit times for Canada, the UK, Ireland, Australia and New Zealand
Cons
- ✗The doses are 30 to 1,000 times below the human trials the vendor's own reference page cites: 30 mg of Ecklonia cava against 72-144 mg, 300 mg of L-arginine against 8.3 g, about 5 mg of phosphatidylserine against 600 mg, about 3.5 mg of curcuminoids against hundreds of milligrams
- ✗'1% Glucoraphanin 5 mg' is 50 micrograms of glucoraphanin, less than you would get from a bite of broccoli, and it is listed as if it were an active ingredient
- ✗The sales page names seven ingredients while the label lists eight; L-ornithine alpha-ketoglutarate is on the bottle and appears nowhere in the sales copy
- ✗The orexin mechanism that names the product has never been shown in a human trial: no supplement has been demonstrated to raise orexin in people, let alone to cause weight loss that way
