Certain research studies on garcinia have shown that the supplement can help to lower cholesterol and promote weight loss, while others have concluded that garcinia can cause liver problems, headache, diarrhea and vertigo, according to WebMD. It is always best to consult with a physician prior to using the supplement.
Studies have shown that daily intake of up to 2,800 milligrams of garcinia is considered safe for human consumption, according to Healthline. However, the supplement may cause low blood sugar levels, especially in individuals with diabetes or those taking medications that alter blood sugar levels. Garcinia is not recommended for children under the age of 18 or pregnant women.
