Effectiveness Rating: Vitamin E vs Whey Protein

The effectiveness rating is a measure of the supplements' ability to increase muscle mass. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up whey protein to increase muscle mass is much better than the evidence backing up vitamin e. Whey Protein should provide positive results while vitamin e will not.

Confidence Rating: Vitamin E vs Whey Protein

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.

Whey Protein's confidence rating is higher than vitamin e's. This means whey protein's effectiveness rating from above is more valid. This does not necessarily mean that whey protein works better, it simply means the evidence (included in this database) backing up whey protein is more established.
