Effectiveness Rating: Casein Protein vs HMB

The effectiveness rating is a measure of the supplements' ability to increase strength. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up casein protein is great, while the evidence backing up hmb is good. Casein Protein should be able to increase strength more effectively, however both supplements should provide positive results.

Confidence Rating: Casein Protein vs HMB

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.

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