HCA
Hydroxycitric acid (HCA) is a natural compound from Garcinia cambogia widely used for weight management, with modest evidence and important safety considerations.
Hydroxycitric acid (HCA) is primarily extracted from the rind of Garcinia cambogia and commonly marketed for weight loss and metabolic health. It is believed to work by inhibiting fat synthesis and suppressing appetite, though effects are generally modest. Safety concerns exist regarding rare but serious liver toxicity and drug interactions.
Evidence for HCA's weight loss effects is mixed and generally modest. Some clinical studies show small benefits in weight reduction and lipid lowering, but meta-analyses question its clinical significance and highlight high variability in results across populations. There are rare but serious cases of liver toxicity, prompting regulatory warnings.
Modest weight loss support
MixedSupplementation with HCA may produce a small reduction in body weight compared to placebo, though effects are inconsistent across studies.
Appetite suppression
LimitedSome evidence suggests HCA can help reduce appetite and food intake by potentially increasing brain serotonin levels.
Improvement in blood lipid profile
LimitedHCA supplementation may lower total and LDL cholesterol, though more evidence is needed to confirm long-term benefits and clinical relevance.
