Effectiveness Rating: Anthocyanins vs Fish Oil

The effectiveness rating is a measure of the supplements' ability to decrease fatigue. This rating answers the question of whether or not a supplement does what it claims. Both anthocyanins and fish oil have good (but not great) evidence showing they may be able to decrease fatigue. Both supplements should provide some positive results.

Confidence Rating: Anthocyanins 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.

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