Effectiveness Rating: Glutamine vs Phosphorus

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 shows phosphorus is better than glutamine in its ability to improve cardiovascular endurance. Phosphorus should provide some positive results while glutamine will not.

Confidence Rating: Glutamine vs Phosphorus

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.

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