Effectiveness Rating: L-Citrulline vs Vitamin B5 (Pantothenic Acid)

The effectiveness rating is a measure of the supplements' ability to improve cycling performance. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up l-citrulline to improve cycling performance is much better than the evidence backing up vitamin b5 (pantothenic acid). L-Citrulline should provide positive results while vitamin b5 (pantothenic acid) will not.

Confidence Rating: L-Citrulline vs Vitamin B5 (Pantothenic Acid)

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 l-citrulline and vitamin b5 (pantothenic acid) 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.
