Effectiveness Rating: Phosphatidylserine vs Tyrosine

The effectiveness rating is a measure of the supplements' ability to improve cycling performance. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up phosphatidylserine to improve cycling performance is much better than the evidence backing up tyrosine. Phosphatidylserine should provide positive results while tyrosine will not.

Confidence Rating: Phosphatidylserine vs Tyrosine

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.

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