Fat burner ingredients: the common ten and what the evidence found
Fat burner ingredients are mostly caffeine sources and plant extracts, and the evidence for them is weak. NIH finds small effects for green tea and chromium, no weight change for forskolin in trials, and too little research for raspberry ketone. This guide rates the common ten in plain terms.

The basics01
What are the most common fat burner ingredients?
Caffeine and caffeine plants lead the list. Chromium, capsicum and a few extracts fill most of the rest.
NIH reviews these one by one and quotes the GAO that little is known about whether weight loss supplements are effective (NIH ODS, Weight Loss). NCCIH adds that natural does not necessarily mean safe (NCCIH, Weight Control).
The ten02
How are the ten common ingredients rated?
None earns a strong rating. The best are small, and several show nothing.
| Ingredient | What was found |
|---|---|
| Caffeine | Up to 400 mg a day is considered safe for healthy adults; stacking stimulants can intensify effects (NIH ODS, Weight Loss) |
| Guarana | Its effects are tied to its caffeine; no weight-loss evidence shown (MSKCC About Herbs, Guarana) |
| Green tea | About 0.95 kg more loss than placebo across 14 trials; liver injury reports with extracts (NIH ODS, Weight Loss) |
| Chromium | About 1.1 kg more across 9 trials, of debatable clinical relevance (NIH ODS, Weight Loss) |
| Capsicum | Less eaten per meal, but no change in body weight at 4 mg a day (NIH ODS, Weight Loss) |
| Forskolin | 500 mg a day for 12 weeks did not reduce body weight (NIH ODS, Weight Loss) |
| African mango | Small trials, mostly by the same authors (NIH ODS, Weight Loss) |
| Raspberry ketone | Insufficient research; studied only in combinations (NIH ODS, Weight Loss) |
| Bitter orange | Studied, but not shown effective for weight loss (NCCIH, Weight Control) |
| Chitosan | Studied, but not shown effective for weight loss (NCCIH, Weight Control) |
Stacking03
Which fat burner ingredients add up to too much caffeine?
Caffeine, guarana and green tea add up, and labels rarely say how much comes from each.
All sources
The 400 mg figure covers coffee, drinks and pills together.
Plant names
Guarana seeds contain caffeine, so a plant name can mean a stimulant (MSKCC About Herbs, Guarana).

Which of these are in Jellutide?
None of the ten. The Jellutide bottle label lists apple cider vinegar and BHB salts in a 525 mg blend.
The sales page names a longer herb list that includes several of the ten. We follow the label and suggest you read the bottle that arrives. See the sales-page formula for that list.
Keep taking any prescribed medicine, and ask a pharmacist before adding a stimulant.

FAQ05
Fat burner ingredient questions
Which fat burner ingredient has the most research?
Green tea and chromium have the largest trials in the NIH review: 14 trials for green tea and 9 for chromium (NIH ODS, Weight Loss). Both showed small gains of about 1 kg over placebo, and the chromium result was called of debatable clinical relevance.
Is bitter orange a safe fat burner ingredient?
NCCIH says bitter orange has been studied for weight loss but not shown effective, and that each studied ingredient has side effects (NCCIH, Weight Control). Ask a pharmacist first, because it is often sold alongside caffeine.
Does guarana count as caffeine?
Yes. MSKCC says guarana seeds contain caffeine and many of its effects are credited to caffeine (MSKCC About Herbs, Guarana). If a label lists guarana, add it to your daily caffeine count.
