Effectiveness Rating: Glucomannan vs Soy Protein

The effectiveness rating is a measure of the supplements' ability to increase HDL (good) cholesterol levels. This rating answers the question of whether or not a supplement does what it claims. The evidence shows soy protein is better than glucomannan in its ability to increase HDL (good) cholesterol levels. Soy Protein should provide some positive results while glucomannan will not.

Confidence Rating: Glucomannan vs Soy 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.

Both glucomannan and soy protein have low confidence ratings. This means neither supplement has an adequate amount of research to back up this claim. A low confidence rating questions the validity of the effectiveness rating.
