Effectiveness Rating: Potassium vs Resveratrol

The effectiveness rating is a measure of the supplements' ability to lower blood pressure. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up potassium to lower blood pressure is much better than the evidence backing up resveratrol. Potassium should provide positive results while resveratrol will not.

Confidence Rating: Potassium vs Resveratrol

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.

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