Effectiveness Rating: Methylsulfonylmethane (MSM) vs N-Acety-L-Cysteine

The effectiveness rating is a measure of the supplements' ability to reduce muscle damage. This rating answers the question of whether or not a supplement does what it claims. The evidence shows methylsulfonylmethane (msm) is better than n-acety-l-cysteine in its ability to reduce muscle damage. Methylsulfonylmethane (MSM) should provide some positive results while n-acety-l-cysteine will not.

Confidence Rating: Methylsulfonylmethane (MSM) vs N-Acety-L-Cysteine

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.

N-Acety-L-Cysteine's confidence rating is higher than methylsulfonylmethane (msm)'s. This means n-acety-l-cysteine's effectiveness rating from above is more valid. This does not necessarily mean that n-acety-l-cysteine works better, it simply means the evidence (included in this database) backing up n-acety-l-cysteine is more established.
