Effectiveness Rating: Epicatechin vs Fish Oil

The effectiveness rating is a measure of the supplements' ability to improve cycling performance. This rating answers the question of whether or not a supplement does what it claims. The evidence shows fish oil is better than epicatechin in its ability to improve cycling performance. Fish Oil should provide some positive results while epicatechin will not.

Confidence Rating: Epicatechin vs Fish Oil

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 epicatechin and fish oil 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.
