A good number of brands of Garcinia Cambogia supplements in the market have claims of 80% and even 95% HCA content. In fact, private label contract manufacturers are marketing these higher content claims big time now.
For full disclosure, we have our own brand of Garcinia Cambogia supplement - BIOTICZONE Garcinia Cambogia with 65% HCA, 1500 mg per serving and 90 Veggie capsules
Before, I start a discussion, here is an important definition of a Herbal Extract
A standardized extract is a process by which one active constituent is extracted from the original herb. In this case, herb is Garcinia Cambogia and active constituent is Hydroxy Citric Acid (HCA)
Here are some facts about Hydroxy Citric Acid (HCA)
- As the name speaks for itself, HCA is an acid in liquid form. To put it in capsules, a salt is added which makes it a powder and hence can be easily encapsulated. Salts may be Calcium, Potassium or Chromium
- HCA extract in liquid form can be as high as 95% content but once a salt is added to it, the content decreases. Depending on number of salts added, the HCA extract content is lower and is anywhere from 50-70%.
- The highest concentration of HCA extract when a salt is added is 70% and not a percentage more. It is scientifically not possible.
Based on the above facts, questions need to be asked of the private label contract manufacturers and brand owners who claim high HCA content
- If the label claims 95% HCA then does it mean that the capsules contain liquid instead of powder ? There are only two possible outcomes - either the capsules contain HCA liquid or the contract manufacturer/brand owner is blatantly misleading consumers about the HCA extract content claims
- Some contract manufacturers/brands claim that their HCA is a blend which makes it 80 %, 85% and 95% instead of a standardized extract. Do they define what the blend is and what ingredients go into their 'blend' ?
