Garcinia Cambogia Dried Fruit Extract
Also known as: Garcinia gummi-gutta, Malabar tamarind, Brindleberry, Garcinia cambogia
Overview
Garcinia cambogia is a tropical fruit native to India and Southeast Asia, known for its distinctive rind, which is a popular component in cooking and traditional medicine. The fruit extract is commonly utilized as a dietary supplement primarily aimed at weight loss. The active ingredient in Garcinia cambogia is hydroxycitric acid (HCA), which is believed to have anti-obesity properties, such as inhibiting fat synthesis and suppressing appetite. Although research into Garcinia cambogia is extensive, findings can be contradictory, with some systematic reviews and meta-analyses offering solid support for its use while acknowledging uncertainties in quality and efficacy. Forms such as capsules or tablets are typical for supplementation.
Benefits
Evidence suggests that Garcinia cambogia may contribute to weight loss, with a systematic review reporting a mean weight reduction of -1.34 kg, a decrease in BMI of -0.99 kg/m2, and a reduction in waist circumference of -4.16 cm compared to placebo. These outcomes indicate a potential benefit primarily in overweight and obese individuals. However, the effect size is small, and clinical significance remains a topic of debate. Some studies also hint at possible improvements in metabolic parameters and fat reduction, although results vary widely. Generally, benefits are observed over 8 to 12 weeks of supplementation.
How it works
Garcinia cambogia exerts its effects primarily through its active compound, HCA, which is thought to inhibit the enzyme citrate lyase. This enzyme plays a crucial role in fatty acid synthesis, thereby potentially reducing fat accumulation within the body. Additionally, HCA may modulate appetite regulation through its interaction with serotonin receptors, contributing to overall decreased food intake. The precise bioavailability of HCA is not well-established, and it is generally recognized that HCA absorption is relatively low.
Side effects
Garcinia cambogia is generally regarded as safe for short-term use; however, its long-term safety profile lacks robust data. Common side effects (occurring in over 5% of users) include gastrointestinal disturbances such as nausea and diarrhea. Less frequently reported side effects (1-5%) comprise headaches and dizziness. Very rare instances (<1%) of potential liver toxicity have been documented, yet a direct causal link remains unconfirmed. Caution is advised for individuals on diabetes medications or blood thinners, and it is contraindicated in pregnant or breastfeeding women, as well as those with certain medical conditions like diabetes. Special care should also be taken by individuals with liver disease or when combining with other pharmaceuticals.
Dosage
The commonly recommended dosage of Garcinia cambogia ranges from 500 to 2,000 mg of HCA per day, with most clinical studies utilizing a range of 1,000 to 2,000 mg daily for optimal effectiveness. It is often advised to take the supplement before meals to enhance appetite suppression. The upper limit of safety for Garcinia cambogia is not well established; however, doses exceeding 2,000 mg daily are infrequently studied. Bioavailability can be influenced by food intake, suggesting that taking the supplement with meals may improve absorption.
