Garcinia cambogia is an extremely popular “weight-loss” supplement in the US thanks in part to Dr. Oz, so much that one million Americans a month “google” the product.
According to the website WebMD, G. cambogia is a tropical fruit also known as the Malabar tamarind, is a popular weight-loss supplement. People say it blocks your body’s ability to make fat and it puts the brakes on your appetite.
They go on to say that hydroxycitric acid, or HCA, is the active ingredient.
Despite little scientific evidence supporting the efficacy of garcinia extract for weight loss/appetite suppression, weight-loss and dietary supplements are a multi-billion dollar business.
In a recent study by the supplement review service, LabDoor, they find that 70% of the top-rated Garcinia Cambogia Supplements do not contain their active ingredients, and there are additional label inaccuracies.
“Supplement manufacturers have been quick to jump on the weight-loss bandwagon, yet many of them lack accountability and provide little proof of product quality and the FDA isn’t solving these problems,” says Neil Thanedar, CEO of LabDoor. “Weight-management supplements have soared in popularity in recent years. Garcinia supplements are available for mass-market purchase, despite a lack of conclusive evidence of efficacy.”
LabDoor looked at 29 garcinia cambogia supplements to determine the actual content of HCA and contaminants like heavy metals.
They say the testing process is as follows:
Our scientists buy products in the same fashion as the average consumer – through retail stores and online sites.
These samples are run through a series of analytical chemical assays to measure active ingredient content and identify potential contaminants. All testing is performed in FDA-registered analytical chemistry laboratories.
Our algorithms then create ratings for each product along five axes – label accuracy, product purity, nutritional value, ingredient safety, and projected efficacy.
Their findings include the vast majority of tested products (21/29) recording negative label claim variances. Of the 21 products recording less HCA content than claimed, 12 products recorded at least 75% less HCA and 9 products recorded at least 85% less HCA than claimed.
The average product recorded 42.1% less hydroxycitric acid (HCA) content than claimed.
Samples of every Garcinia supplement passed all six heavy metal assays.
