Effectiveness Rating: Anthocyanins vs Eicosapentaenoic Acid (EPA)

The effectiveness rating is a measure of the supplements' ability to improve cardiovascular endurance. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up anthocyanins to improve cardiovascular endurance is much better than the evidence backing up eicosapentaenoic acid (epa). Anthocyanins should provide positive results while eicosapentaenoic acid (epa) will not.

Confidence Rating: Anthocyanins vs Eicosapentaenoic Acid (EPA)

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 eicosapentaenoic acid (epa)'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.
