The effectiveness rating is a measure of the supplements' ability to improve muscular endurance. This rating answers the question of whether or not a supplement does what it claims.

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.

This does not necessarily mean that beta alanine works better, it simply means the evidence (included in this database) backing up beta alanine is more established.
