A group from The Stockton College of New Jersey tested six (very) popular protein supplements for their actual Branched Chain Amino Acid Content and compared that with the BCAA claims made on the package. The group was comprised of the GNC house brand, Muscle Milk, BSN’s Syntha 6, Isoflex, Cellucor, Optimum Nutrition’s Gold Standard Whey (which I use to recommended until now), and their Hydrowhey (another product I used to recommended until seeing these tests).
Here’s a look at the subjective (or jump ahead to the graph below, which breaks down merchandise claims versus real sums):
The following chart represents the results from the study, with the product name to the far left, the actual (tested) milligrams of BCAA in the center column, and the amount of claimed milligrams to the right:
None of the products were even close to their promised level of BCAAs…
I can’t comprehend why Syntha 6 isn’t very high, also how does GNC claim 15mg and then only contain two grams of BCAA. But the proof is out there, as is the poster demo, so these firms have some explaining to do, and a few evaluations to refute ( in case that they can), because right now they seem grossly fraudulent.
And Lanham Act suits and the way class action happen to be flying around the business, I wouldn’t be surprised to find BCAA-established measurements soon.
Here’s the poster demo:
