Effectiveness Rating: Anthocyanins vs Creatine Monohydrate

The effectiveness rating is a measure of the supplements' ability to improve running performance. 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 creatine monohydrate is good. Anthocyanins should be able to improve running performance more effectively, however both supplements should provide positive results.

Confidence Rating: Anthocyanins vs Creatine Monohydrate

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 anthocyanins and creatine monohydrate 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.
