Effectiveness Rating: Arachidonic Acid vs Chromium

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 arachidonic acid is better than chromium in its ability to increase muscle mass. Arachidonic Acid should provide some positive results while chromium will not.

Confidence Rating: Arachidonic Acid vs Chromium

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.

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