Effectiveness Rating: Coenzyme Q10 vs Glycerol

The effectiveness rating is a measure of the supplements' ability to improve cardiovascular endurance. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up glycerol is great, while the evidence backing up coenzyme q10 is good. Glycerol should be able to improve cardiovascular endurance more effectively, however both supplements should provide positive results.

Confidence Rating: Coenzyme Q10 vs Glycerol

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 coenzyme q10 and glycerol have great confidence rating. This means both supplement's effectiveness ratings above are valid.
