Weight Loss Supplements That Work: An Honest List
Weight loss supplements that work do so only a little. The NIH fact sheet reports gains of about 1 kg or less over placebo for the best-studied ones, such as green tea, chromium and carnitine. No supplement replaces food and movement, and none works for everyone.

The list01
Which weight loss supplements that work have any evidence?
A few have small, uncertain effects. None has a strong record.
The NIH Office of Dietary Supplements pooled the trials. Even the best results are around a kilogram, which is about two pounds, over several months (NIH ODS, Supplements for Weight Loss).
| Ingredient | Reported extra loss | Catch |
|---|---|---|
| Green tea | 0.95 kg | Extracts linked to liver damage |
| Chromium | 1.1 kg | "Debatable clinical relevance" |
| Carnitine | 1.33 kg | Nausea and diarrhea possible |
| Garcinia | 0.88 kg | Not significant in the two rigorous trials |
Size of the effect02
How much weight can a supplement really take off?
About one kilogram is the best case in the table, and it is not a promise. For comparison, the NHLBI suggests aiming for 5% to 10% of your starting weight over about 6 months (NHLBI, Aim for a Healthy Weight).
Do the math with the calculator. A one-kilogram change is small beside a 5% goal.

- 10% goalType a weight to see it.
- At 1-2 lb a weekWeeks to the 5% goal.
NHLBI suggests aiming to lose 5-10% of your starting weight over about 6 months (NHLBI, Aim for a Healthy Weight), and the CDC says people who lose 1-2 pounds a week are more likely to keep it off (CDC, Steps for Losing Weight). A planning aid, not medical advice.
Not on the list03
Which supplements are sold for weight loss without proof?
Most of them. NCCIH found none of the studied supplements effective, and each had side effects (NCCIH, Weight Control).
Raspberry ketone has only been tested in combinations, and African mango trials were small and short (NIH ODS, Supplements for Weight Loss). Both appear on the seller's sales page, not on the bottle label.

Where does Jellutide fit among weight loss supplements that work?
Jellutide is not on the evidence list, because its two label ingredients, apple cider vinegar and BHB salts, are not in the NIH table. No trial has tested the gummy itself.
Vinegar at 15 or 30 mL a day, far more than a gummy holds, moved weight about 1 to 2 kg in one maker-linked trial, then faded after stopping (Kondo 2009, vinegar trial).
That is why we call the gummy a support, not a fix. The Supplement Facts page has the line-by-line math.

FAQ06
Questions
What is the best supplement for weight loss?
No supplement is the best. Green tea, chromium and carnitine show gains near one kilogram over placebo in pooled trials, and those gains may not matter in daily life. Food, sleep and movement still do the heavy lifting.
Do natural weight loss supplements work better?
Not by default. Natural does not necessarily mean safe, and NCCIH found no studied supplement shown to be effective (NCCIH, Weight Control). Judge each product by its ingredients, doses and trials.
Can I trust reviews of weight loss supplements?
Be careful. Fake and paid reviews are common enough that the FTC wrote a rule against them in 2024 (FTC, Fake reviews rule (2024)). Look for dosed ingredients and trials, not star scores.
