Effectiveness Rating: Choline Bitartrate vs L-Carnitine

The effectiveness rating is a measure of the supplements' ability to decrease fatigue. This rating answers the question of whether or not a supplement does what it claims. The evidence shows neither choline bitartrate nor l-carnitine has the ability to decrease fatigue. Neither supplement will provide positive results for this claim.

Confidence Rating: Choline Bitartrate vs L-Carnitine

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 choline bitartrate and l-carnitine 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.
