Effectiveness Rating: Betaine vs Fenugreek

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 fenugreek is better than betaine in its ability to increase strength. Fenugreek should provide some positive results while betaine will not.

Confidence Rating: Betaine vs Fenugreek

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 fenugreek'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.
