Effectiveness Rating: D-Aspartic Acid vs Glycerol Monostearate

The effectiveness rating is a measure of the supplements' ability to increase muscle mass. This rating answers the question of whether or not a supplement does what it claims. The evidence shows glycerol monostearate is better than d-aspartic acid in its ability to increase muscle mass. Glycerol Monostearate should provide some positive results while d-aspartic acid will not.

Confidence Rating: D-Aspartic Acid vs Glycerol Monostearate

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 d-aspartic acid and glycerol monostearate 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.
