Effectiveness Rating: Astaxanthin vs Leucine

The effectiveness rating is a measure of the supplements' ability to reduce muscle damage. This rating answers the question of whether or not a supplement does what it claims. The evidence shows astaxanthin is better than leucine in its ability to reduce muscle damage. Astaxanthin should provide some positive results while leucine will not.

Confidence Rating: Astaxanthin vs Leucine

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 astaxanthin and leucine 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.
