Effectiveness Rating: Anthocyanins vs Peak O2

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 is great, while the evidence backing up peak o2 is good. Anthocyanins should be able to improve cardiovascular endurance more effectively, however both supplements should provide positive results.

Confidence Rating: Anthocyanins vs Peak O2

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 peak o2'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.
