Effectiveness Rating: Arginine vs Beta Alanine

The effectiveness rating is a measure of the supplements' ability to improve cycling sprint performance. This rating answers the question of whether or not a supplement does what it claims. The evidence shows beta alanine is better than arginine in its ability to improve cycling sprint performance. Beta Alanine should provide some positive results while arginine will not.

Confidence Rating: Arginine vs Beta Alanine

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 arginine and beta alanine 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.
