Effectiveness Rating: Flaxseed Oil vs Psyllium

The effectiveness rating is a measure of the supplements' ability to lower LDL (bad) cholesterol levels. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up psyllium to lower LDL (bad) cholesterol levels is much better than the evidence backing up flaxseed oil. Psyllium should provide positive results while flaxseed oil will not.

Confidence Rating: Flaxseed Oil 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.

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