Effectiveness Rating: Glycine-Arginine-Alpha-Ketoisocaproic Acid (GAKIC) vs Zinc Magnesium Aspartate (ZMA)
The effectiveness rating is a measure of the supplements' ability to increase strength. This rating answers the question of whether or not a supplement does what it claims. The evidence shows neither glycine-arginine-alpha-ketoisocaproic acid (gakic) nor zinc magnesium aspartate (zma) has the ability to increase strength. Neither supplement will provide positive results for this claim.
Confidence Rating: Glycine-Arginine-Alpha-Ketoisocaproic Acid (GAKIC) 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 glycine-arginine-alpha-ketoisocaproic acid (gakic) 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.
