Quick answer: AlkaMelt names four ingredients: apple cider vinegar, green tea extract, berberine and cayenne pepper. Per-serving amounts are not published, and its official reference list cites some ingredients that are not in the formula.

Each ingredient and the evidence
Apple Cider Vinegar
Acetic acid is the active part. A 12-week Japanese trial found adults taking 15 to 30 ml of vinegar a day lost a little more weight than placebo. Other results on appetite and after-meal blood sugar are small and mixed.
ACV research on PubMedGreen Tea Extract
Catechins such as EGCG may slightly raise energy use and fat burning. Reviews find small effects. Very high doses of concentrated extract have been linked to rare liver problems.
NCCIH on green teaBerberine
A plant compound with real human research on blood sugar and cholesterol, usually at about 1,000 to 1,500 mg a day. It can interact with several medicines and is not for pregnancy.
Berberine research on PubMedCayenne Pepper
Capsaicin gives a short burst of warmth and may add a small amount of daily calorie burn and reduce appetite slightly. The effect is modest.
Capsaicin research on PubMedHow research doses compare
| Ingredient | Typical research dose |
|---|---|
| Apple cider vinegar | 15 to 30 ml vinegar a day |
| Green tea catechins | about 300 to 600 mg a day |
| Berberine | 1,000 to 1,500 mg a day |
| Capsaicin | 2 to 6 mg a day |
Our take: a 30 ml bottle lasting a month cannot hold 15 ml of vinegar per day, so AlkaMelt is certainly not dosed like the vinegar trials. The other amounts are unknown.
The reference list mismatch
The official site cites studies on glucomannan, chromium picolinate, L-carnitine, green coffee extract and caffeine. None of these are in AlkaMelt. Read why this matters.
