Effectiveness Rating: Green Coffee Extract vs Olive Leaf Extract

The effectiveness rating is a measure of the supplements' ability to improve insulin sensitivity. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up olive leaf extract to improve insulin sensitivity is much better than the evidence backing up green coffee extract. Olive Leaf Extract should provide positive results while green coffee extract will not.

Confidence Rating: Green Coffee Extract vs Olive Leaf 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 green coffee extract and olive leaf 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.
