Effectiveness Rating: Alpha-Ketoisocaproic Acid vs Magnesium

The effectiveness rating is a measure of the supplements' ability to improve sports performance. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up magnesium to improve sports performance is much better than the evidence backing up alpha-ketoisocaproic acid. Magnesium should provide positive results while alpha-ketoisocaproic acid will not.

Confidence Rating: Alpha-Ketoisocaproic Acid vs Magnesium

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 alpha-ketoisocaproic acid and magnesium 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.
