Effectiveness Rating: Melatonin vs Zinc Magnesium Aspartate (ZMA)

The effectiveness rating is a measure of the supplements' ability to increase levels of growth hormone. This rating answers the question of whether or not a supplement does what it claims.

Melatonin should provide some positive results while zinc magnesium aspartate (zma) will not.

Confidence Rating: Melatonin 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.

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