Metabolism and Excretion In a pharmacokinetic study where five normal adult male volunteers received an oral dose of [3H-methyl]-L-carnitine following 15 days of a high carnitine diet and additional carnitine supplement, 58 to 65% of the administered radioactive dose was recovered in the urine and feces in 5 to 11 days
The study was conducted on 32 male mice divided into four groups: a control (C) group receiving a standard diet with biotin, a biotin-deficient (BD) group on a biotin-free diet, a ketogenic control (KC) group on a ketogenic diet (low-carbohydrate and high-fat) with biotin, and a ketogenic biotin-deficient (KBD) group on a ketogenic diet without biotin
