Effectiveness Rating: Sodium 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 backing up sodium to improve cycling sprint performance is much better than the evidence backing up zinc magnesium aspartate (zma). Sodium should provide positive results while zinc magnesium aspartate (zma) will not.

Confidence Rating: Sodium 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.

Sodium's confidence rating is higher than zinc magnesium aspartate (zma)'s. This means sodium's effectiveness rating from above is more valid. This does not necessarily mean that sodium works better, it simply means the evidence (included in this database) backing up sodium is more established.
