Effectiveness Rating: L-Carnitine L-Tartrate vs Whey Protein

The effectiveness rating is a measure of the supplements' ability to reduce muscle soreness. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up l-carnitine l-tartrate to reduce muscle soreness is much better than the evidence backing up whey protein. L-Carnitine L-Tartrate should provide positive results while whey protein will not.

Confidence Rating: L-Carnitine L-Tartrate vs Whey Protein

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 whey protein 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.
