Effectiveness Rating: N-Acety-L-Cysteine vs Zinc Magnesium Aspartate (ZMA)

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 neither n-acety-l-cysteine nor zinc magnesium aspartate (zma) has the ability to improve cycling sprint performance. Neither supplement will provide positive results for this claim.

Confidence Rating: N-Acety-L-Cysteine vs Zinc Magnesium Aspartate (ZMA)

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 n-acety-l-cysteine and zinc magnesium aspartate (zma) 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.
