L-Carnitine Supplements
While bioavailability of L-carnitine from the diet is quite high (see Dietary L-Carnitine), absorption from oral L-carnitine supplements is considerably lower. According to one study, bioavailability of L-carnitine from oral supplements (0.5-6 gram dosage) ranges from 14%-18% of the total dose (5). Less is known regarding the metabolism of the acetylated form of L-carnitine, acetyl-L-carnitine (ALCAR); however, bioavailability of ALCAR is thought to be higher than L-carnitine. The results of in vitro experiments suggest that ALCAR is partially hydrolyzed upon intestinal absorption (10). In humans, administration of 2 grams of ALCAR per day for 50 days increased plasma ALCAR levels by 43%, suggesting that some acetyl-L-carnitine is absorbed without hydrolysis or that L-carnitine is reacetylated in the enterocyte (5).
