Carnitine Side Effects and Warnings
Side Effects and Warnings
L-carnitine in its three forms appears to be quite safe. However, individuals with low or borderline-low thyroid levels should avoid carnitine because it might impair the action of thyroid hormone. ^ Individuals on dialysis should not receive this (or any other supplement) without a physician's supervision.
The maximum safe dosages for young children, pregnant or nursing women, or those with severe liver or kidney disease have not been established.
