Effectiveness Rating: Caffeine Anhydrous vs Capsinoids

The effectiveness rating is a measure of the supplements' ability to improve sprint performance. This rating answers the question of whether or not a supplement does what it claims.

Confidence Rating: Caffeine Anhydrous vs Capsinoids

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.

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