Effectiveness Rating: Anthocyanins vs Beetroot Juice

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.

Confidence Rating: Anthocyanins vs Beetroot Juice

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.

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