How it scores
Every score is derived from publicly verifiable facts. See the full methodology and Value Index formula.
Ingredients & doses
| Ingredient | Dose | Pathway | Notes |
|---|---|---|---|
| Glucomannan | 3000 mg | Fiber satiety (fullness) | Headline soluble fiber, dosed at the EU/EFSA satiety level of 3 g/day (per full 6-capsule serving). |
| Choline | 82.5 mg | Blood-sugar stability | Contributes to normal fat metabolism (EU structure/function claim). |
| Green coffee bean extract | 40 mg | Sustained energy (anti-crash) | Below typical clinical-trial doses. |
| Acai berry extract | 50 mg | Leptin & fat signaling | Antioxidant; preclinical support only. |
How it claims to work
Built around glucomannan, a viscous soluble fiber that absorbs water and expands in the stomach to promote fullness, paired with B-vitamins, choline, chromium, and plant extracts marketed to support normal metabolism.
The evidence
Glucomannan has human RCT data and an EU/EFSA satiety claim at 3 g/day, though a 2014 meta-analysis found no significant weight loss; the green coffee, acai, and B-vitamin additions are largely preclinical or under-dosed.
Strengths
- Glucomannan dosed at the full 3 g/day EFSA satiety level, fully disclosed.
- Caffeine-free.
- Other actives are disclosed (no hidden blend).
Watch-outs
- At 3 g/day, glucomannan sits at the very top of the studied range — large glucomannan doses carry a documented risk of throat, esophageal, or GI blockage if not taken with enough water.
- Six capsules a day, in three pre-meal doses, is a heavy routine.
- The guarantee only applies to the 4-bottle bundle and carries a fee.
Price & value
Taste & format: Six capsules a day — taken as 2 capsules three times daily with a full glass of water before meals.
