The results of animal studies and double blind, placebo controlled human clinical studies, reveal that hydroxycitric acid (HCA) not only reduces weight, but also is safe. No treatment-related side-effects were reported in these studies. Furthermore, the authors conclude that HCA at a dose of up to 2800 mg/d is safe for human consumption. (4)
A laboratory evaluation of rats supplemented with 0, 0.2, 2.0 and 5.0% HCA-SX (Hydroxycitric acid Super CitriMax, derived from the Garcinia cambogia fruit), a popular supplement for weight loss, revealed that HCA-SX reduced body weight without affecting major organs, blood results, or tissue diagnosis of disease.
