Amino Acids - Carnitine - Contraindications / Precautions / Warnings

A number of studies show that L-carnitine is safe and there are no significant side effects.

Vegetarians are likely to be deficient in carnitine as it is primarily obtained from meat. To ensure adequate production of carnitine, take supplements or eat grains, such as cornmeal, that have been fortified with L-lysine.

It is not recommended to take a single amino acid for an extended period of time without supplementing with other amino acids as well. Long-term isolated amino acid supplementation can create an imbalance in the body.
