BCAA REPORT

Labdoor analyzed 12 of the best-selling BCAA supplements in the United States. Our analysis quantified levels of individual amino acids, minerals, and heavy metals.

Isoleucine was the active ingredient with the most inaccuracies in this category. Eighty-two percent of the product in this category overstated isoleucine content, measuring on average 24.3% less isoleucine compared to label claims. Leucine was the most accurate active ingredient in the BCAAs that were tested. On average, products measured 1.0% more leucine than claimed on the label.

Samples of every BCAA supplement passed all four heavy metal assays (Arsenic, Cadmium, Lead and Mercury).
