Effectiveness Rating: Stinging Nettle Root vs Vitamin C

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 stinging nettle root to increase HDL (good) cholesterol levels is much better than the evidence backing up vitamin c. Stinging Nettle Root should provide positive results while vitamin c will not.

Confidence Rating: Stinging Nettle Root 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.

Both stinging nettle root and vitamin c 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.
