An oral controlled-release multiparticulate dosage form comprises a plurality of individually enteric coated particulates containing an L-carnitine that independently disperse in a patient's stomach after oral ingestion and travel through the stomach and past the pyloric sphincter without substantially releasing the L-carnitine in the stomach. The individual particulates contain a solid core containing the L-carnitine, and an enteric coating. The dosage form may be used to treat conditions associated with a reduction of the amount of L-carnitine in the body.
