Effectiveness Rating: Alpha-Ketoisocaproic Acid vs Vitamin E

The effectiveness rating is a measure of the supplements' ability to reduce muscle damage. This rating answers the question of whether or not a supplement does what it claims. Both alpha-ketoisocaproic acid and vitamin e have good (but not great) evidence showing they may be able to reduce muscle damage. Both supplements should provide some positive results.

Confidence Rating: Alpha-Ketoisocaproic Acid vs Vitamin E

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.

Vitamin E's confidence rating is higher than alpha-ketoisocaproic acid's. This means vitamin e's effectiveness rating from above is more valid. This does not necessarily mean that vitamin e works better, it simply means the evidence (included in this database) backing up vitamin e is more established.
