Effectiveness Rating: Flaxseed Oil vs Grape Seed Extract

The effectiveness rating is a measure of the supplements' ability to lower total cholesterol levels. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up grape seed extract to lower total cholesterol levels is much better than the evidence backing up flaxseed oil. Grape Seed Extract should provide positive results while flaxseed oil will not.

Confidence Rating: Flaxseed Oil vs Grape Seed Extract

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 flaxseed oil and grape seed extract 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.
