Studies dating back to the 60's in animals and recently in humans suggest that the amino acid L-carnitine blocks the effects of excess thyroid hormone in some of the body's tissues. L-carnitine does not affect the thyroid gland itself but effectively reduces symptoms of hyperthyroidism in the autoimmune hyperthyroid disorder Graves' disease because of its ability to block the effects caused by excess thyroid hormone.

L-carnitine insufficiency may therefore result from inadequate protein intake (and specifically that of Lysine & Methionine), impaired intestinal absorption, increased protein losses (in urine, stool or from loss of blood or plasma, etc) or possibly impaired L-carnitine synthesis.
Sep 03, 2019· L-carnitine inhibits both triiodothyronine and thyroxine entry into the cell nuclei. This is relevant because thyroid hormone action is mainly mediated by specific nuclear receptors. In one randomized trial, 2 and 4 grams per day of L-carnitine reversed hyperthyroid symptoms. In another study, L-carnitine relieved a "thyroid storm" .
Sep 22, 2016· Twelve weeks of supplementation with 1980 mg of L-carnitine significantly improved physical fatigue levels by 22.9% in participating subjects when compared to control. Hypothyroidism, a condition in which the thyroid gland doesn't produce enough thyroid hormone, is estimated to affect as many as 1 in 20 Americans (1, 2, 3).
Under-active thyroid (hypothyroidism): There is some concern that acetyl-L-carnitine might interfere with thyroid hormone. Don't use acetyl-L-carnitine if you have an under-active thyroid.
In brief, l-carnitine has 1) an antagonist action on the thyroid hormone-elicited increase of serum AST, ALT, GGT, SHBG, and ferritin; 2) a neutral effect on the thyroid hormone-driven decrease of serum TSH and total cholesterol, and increase of urinary excretion of OH-P; and 3) a potentiating effect on the thyroid hormone-driven increase in .
