Effectiveness Rating: Betaine vs Creatine Citrate

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 creatine citrate to increase strength is much better than the evidence backing up betaine. Creatine Citrate should provide positive results while betaine will not.

Confidence Rating: Betaine vs Creatine Citrate

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 citrate'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.
