Which is the best Garcinia cambogia supplement? Many people have asked this question of ConsumerLab.com since last October when The Dr. Oz Show aired a segment about using this herbal supplement for weight management but cautioned that Dr. Oz does not endorse any specific product.
To answer consumers' questions, ConsumerLab.com selected and purchased 11 Garcinia extract supplements on the market and tested each for its amount of hydroxycitric acid (HCA), a plant compound believed to be important to Garcinia's biological effects. ConsumerLab.com found that six of the supplements contained only 16% to 81% of the listed amount of HCA. Two products having the lowest percentages (16% and 22%, respectively) of their listed HCA appeared to be promoting false endorsement by Dr. Oz.
"Garcinia cambogia extract may have a modest benefit in weight management, but most products on the market don't actually deliver what's listed on their labels," said Tod Cooperman, MD, president of ConsumerLab.com. Garcinia is typically taken three times a day approximately one hour before meals, to provide a total daily dose of about 900 mg to 1,500 mg of HCA. However, one of the products which failed ConsumerLab.com's tests provided less than 100 mg of HCA per day. Even among products which contained what they listed, the amount of HCA in a suggested daily serving ranged from as little as 250 mg to as much as 3,150 mg of HCA. Unlike OTC products and prescription medications, for which dosing must be approved by the FDA, dietary supplement companies set their own suggested serving levels, which may or may not correspond to what has been shown to work.
Among the five products which passed testing, the cost to obtain an equivalent amount (1,500 mg) of HCA ranged from 74 cents to $2.08. In products which did not contain what they claimed, this cost was as much as $11.39 based on the amounts of HCA actually present.
