How safe is garcinia cambogia (HCA) for weight loss?

The garcinia cambogia plant and its fruit have been eaten safely for years. The hydroxycitric acid (HCA) extract is also likely safe in normal amounts.

However, don’t take this supplement if you are pregnant or breastfeeding. If you are taking a diabetic medication (like insulin or glyburide), talk to a doctor before taking this to make sure this is right for you, otherwise this supplement may allow your blood sugar to fall even lower than normal.

Those taking a statin (a cholesterol-lowering drug) should use this supplement with caution because it can increase the risk of harmful side effects, like rhabdomyolysis or muscle degradation. Those with Alzheimer's disease or other forms of dementia shouldn’t take HCA because of the risk of worsening dementia.
