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

Beta Alanine should be able to improve sports performance more effectively, however both supplements should provide positive results.

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 creatine monohydrate works better, it simply means the evidence (included in this database) backing up creatine monohydrate is more established.
