What It Actually Is
Garcinia cambogia is a small tropical fruit, and supplements use an extract of the rind standardized for HCA content.
What Research Generally Shows
HCA is studied for its potential to inhibit citrate lyase, an enzyme tied to converting excess carbs to fat, and for supporting appetite signals. Clinical results across studies are mixed.
The Honest Gap
MetaboSwitch's HCA percentage and total garcinia amount aren't disclosed on the packaging we reviewed.
