Effectiveness Rating: L-Carnitine L-Tartrate vs Phosphatidic Acid

The effectiveness rating is a measure of the supplements' ability to increase strength. This rating answers the question of whether or not a supplement does what it claims. The evidence shows phosphatidic acid is better than l-carnitine l-tartrate in its ability to increase strength. Phosphatidic Acid should provide some positive results while l-carnitine l-tartrate will not.

Confidence Rating: L-Carnitine L-Tartrate vs Phosphatidic Acid

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 l-carnitine l-tartrate and phosphatidic acid 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.
