Effectiveness Rating: Alpha-Ketoisocaproic Acid vs Caffeine Anhydrous

The effectiveness rating is a measure of the supplements' ability to improve muscular endurance. This rating answers the question of whether or not a supplement does what it claims. The evidence shows caffeine anhydrous is better than alpha-ketoisocaproic acid in its ability to improve muscular endurance. Caffeine Anhydrous should provide some positive results while alpha-ketoisocaproic acid will not.

Confidence Rating: Alpha-Ketoisocaproic Acid vs Caffeine Anhydrous

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 alpha-ketoisocaproic acid'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.
