Acetylcarnitine supplementation: pharmacodynamics, pharmacokinetics, and clinical efficacy in neuropsychiatric diseases Acetylcarnitine uptake from exogenous sources (e.g., food) The oral bioavailability of acetylcarnitine, similar to that of carnitine, is relatively low, with some studies reporting absorption rates as low as 510% of approximately 2000 mg, which is considered a saturating dose [107, 108]
It is appreciated herein that shorter alkyl and/or alkenyl chains forming cycloalkyl and/or cycloalkenyl, respectively, may add less lipophilicity to the compound and accordingly will have different pharmacokinetic behavior
