Effectiveness Rating: Branched Chain Amino Acids vs N-Acety-L-Cysteine

The effectiveness rating is a measure of the supplements' ability to improve cardiovascular endurance. This rating answers the question of whether or not a supplement does what it claims. The evidence shows neither branched chain amino acids nor n-acety-l-cysteine has the ability to improve cardiovascular endurance. Neither supplement will provide positive results for this claim.

Confidence Rating: Branched Chain Amino Acids vs N-Acety-L-Cysteine

Another factor to take into account when comparing supplements is the confidence rating. This rating is a measure of how valid each supplement's effectiveness rating is. Remember, the confidence rating is a measure of how much you can trust the effectiveness rating. This rating is based on how many studies are included in the database on a supplement's claims. Ideally, you want a high effectiveness AND confidence rating.

Both branched chain amino acids and n-acety-l-cysteine have low confidence ratings. This means neither supplement has an adequate amount of research to back up this claim. A low confidence rating questions the validity of the effectiveness rating.
