Effectiveness Rating: Arginine vs Branched Chain Amino Acids

The effectiveness rating is a measure of the supplements' ability to decrease protein breakdown. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up arginine is great, while the evidence backing up branched chain amino acids is good. Arginine should be able to decrease protein breakdown more effectively, however both supplements should provide positive results.

Confidence Rating: Arginine vs Branched Chain Amino Acids

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.

Branched Chain Amino Acids's confidence rating is higher than arginine's. This means branched chain amino acids's effectiveness rating from above is more valid. This does not necessarily mean that branched chain amino acids works better, it simply means the evidence (included in this database) backing up branched chain amino acids is more established.
