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
Metabo Drops
Pros
- ✓Designed around a daily habit, which solves the most common reason supplements fail: people forget to take them
- ✓L-theanine plus caffeine is a well-studied pairing for focused, less jittery energy, and your coffee supplies the caffeine
- ✓Chlorogenic acid, L-carnitine and chromium each have randomized-trial meta-analyses showing modest weight effects
- ✓One-time payment with no autoship. The checkout page shows no rebilling on any bundle
- ✓Refunds are handled through ClickBank rather than directly by the brand
Cons
- ✗No doses published for any ingredient, and the 'vitamin complex' isn't even named, so you can't compare it with the trial amounts
- ✗'One drop' is a very small serving next to the hundreds of milligrams used in most of the ingredient studies
- ✗Sales page claims like 'scientifically proven' and 'zero side effects' aren't backed by any published trial of the product
- ✗No single-bottle option: the smallest order is two bottles at $158 plus $9.95 shipping
