Effectiveness Rating: Betaine vs Creatine Nitrate

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 shows creatine nitrate is better than betaine in its ability to increase strength. Creatine Nitrate should provide some positive results while betaine will not.

Confidence Rating: Betaine vs Creatine Nitrate

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.

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