Effectiveness Rating: Arginine vs Vitamin C

The effectiveness rating is a measure of the supplements' ability to improve recovery. This rating answers the question of whether or not a supplement does what it claims. The evidence shows arginine is better than vitamin c in its ability to improve recovery. Arginine should provide some positive results while vitamin c will not.

Confidence Rating: Arginine vs Vitamin C

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.

Arginine's confidence rating is higher than vitamin c's. This means arginine's effectiveness rating from above is more valid. This does not necessarily mean that arginine works better, it simply means the evidence (included in this database) backing up arginine is more established.
