Effectiveness Rating: Garlic Extract vs Quercetin

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. Both garlic extract and quercetin have good (but not great) evidence showing they may be able to lower blood pressure. Both supplements should provide some positive results.

Confidence Rating: Garlic Extract vs Quercetin

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.

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