Effectiveness Rating: Psyllium vs Vitamin C

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 is great, while the evidence backing up vitamin c is good. Psyllium should be able to lower LDL (bad) cholesterol levels more effectively, however both supplements should provide positive results.

Confidence Rating: Psyllium vs Vitamin C

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 vitamin c'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.
