Effectiveness Rating: Krill Oil vs Soy Protein

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

Confidence Rating: Krill Oil vs Soy Protein

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.

Soy Protein's confidence rating is higher than krill oil's. This means soy protein's effectiveness rating from above is more valid. This does not necessarily mean that soy protein works better, it simply means the evidence (included in this database) backing up soy protein is more established.
