Effectiveness Rating: Garlic Extract vs Psyllium

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 backing up psyllium to increase HDL (good) cholesterol levels is much better than the evidence backing up garlic extract. Psyllium should provide positive results while garlic extract will not.

Confidence Rating: Garlic Extract vs Psyllium

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 garlic extract and psyllium 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.
