Quick answer: The ingredients are plant extracts with long histories of use. Research on each for weight is limited or mixed, amounts are not published, and we know of no clinical trials on the finished product.
African mango
Small studies exist, mostly short and of mixed quality. See African Mango Explained.
Green tea extract
Reviews suggest at most a modest effect on weight, and there are rare liver safety reports. See Green Tea Extract Explained.
Garcinia cambogia
Research results are mixed and modest overall. See Garcinia Cambogia Explained.
Maca root
Maca has traditional use as an energy tonic, and evidence for weight is limited. See Maca Root Explained.
Where it falls short
The seller does not publish per-serving amounts, so the formula cannot be compared with research doses. We do not claim the product melts fat or causes weight loss on its own.
Bottom line
A familiar set of ingredients with limited evidence for any specific outcome. See our worth-it review and the references.
