Rolle of HCA in weight loss supplements

Hydroxycitric acid (HCA) is otherwise known as Garcinia Cambogia and derives from the dried rind of the Garcinia Cambogia (family Guttiferae) fruit.

What does it do and what scientific studies give evidence to support this?

Hydroxycitric acid has been used for centuries as a food condiment in Southeastern Asia to make food more filling and satisfying. Hydroxycitric Acid (HCA) is a popular ingredient in commercial weight-loss preparations. Research has shown that HCA is effective at triggering safe weight-loss - even in untrained men and women. Animal studies have shown that HCA improves glucose function, increases serotonin levels, and is effective at weight restriction. HCA also shifts the bodies preferred energy source from carbohydrates to fats. 

In athletes, HCA increases lipolysis and may improve the synthesis of Ach - Acetycholine. Acetycholine is a neurotransmitter responsible for muscular contraction, and an improvement in its synthesis may improve athletic performance by increasing exercise endurence. By potentiating the effects of 5-HT, HCA may prove effective in the treatment of depression, insomnia and migraine headaches. When used in conjunction with pyruvate and carnitine, HCA may be more effective at promoting fat loss, and Hydroxycitric acid has been shown to elicit weight loss without stimulating the central nervous system. Research also demonstrates that HCA has antibacterial properties and may thus offer immune system protection.

All persons can benefit from hydroxycitric acid supplementation.

How much should be taken? Are there any side effects?

Strictly adhere to label recommendations. Research has shown that HCA supplementation is non-toxic to humans, even in high doses.
