Hydroxycitric acid (HCA) comes from the rind of Garcinia cambogia fruit. Supplements mainly target weight management.
HCA blocks an enzyme called ATP-citrate lyase. Your body uses that enzyme to turn carbohydrates into stored fat. People take it hoping to curb appetite or slow fat buildup.
Take HCA 30 to 60 minutes before meals. Capsules and tablets are the usual forms. Many weight-loss blends stack it with other ingredients.
Digestive upset and headaches show up as the most common side effects. HCA can shift blood sugar levels, so anyone on diabetes medication should check with a doctor first. Safety during pregnancy or breastfeeding remains unclear.
