Garcinia cambogia is an extract from a tropical fruit whose active ingredient is hydroxycitric acid (HCA). HCA inhibits the enzyme ATP citrate lyase involved in fatty acid synthesis and raises serotonin levels in the brain, reducing appetite and emotional overeating. A typical dose is 500-1000 mg of HCA three times daily, taken 30-60 minutes before meals.
Garcinia's effect on weight loss has been modest in studies — averaging 1-2 kg more than placebo over 8-12 weeks. Best results come from studies using at least 50% HCA content and doses above 1,500 mg HCA daily. Garcinia works best alongside dietary control and regular exercise, not as a standalone solution.
Garcinia should be taken on an empty stomach, 30-60 minutes before main meals. This gives HCA time to absorb and exert its appetite-suppressing effect before eating. Split your daily dose into three portions (morning, lunch, dinner). Take the capsule with a glass of water to promote absorption and reduce stomach discomfort.
Most people tolerate Garcinia well at recommended doses. Possible mild side effects include headache, digestive upset, and dry mouth. Garcinia should not be taken alongside certain antidepressants (SSRIs) because HCA raises serotonin levels. Pregnant and breastfeeding women are advised against using Garcinia.
