Effectiveness Rating: Betaine vs Whey Protein

The effectiveness rating is a measure of the supplements' ability to decrease body fat. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up betaine is great, while the evidence backing up whey protein is good. Betaine should be able to decrease body fat more effectively, however both supplements should provide positive results.

Confidence Rating: Betaine 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 betaine'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.
