Acetyl-L-carnitine or ALCAR, is an acetylated form of L-carnitine. ALCAR has been claimed to be superior to normal L-carnitine in terms of bioavailability. However, at least one study has suggested that the acetylated form may have a lower oral bioavailability.[1]

Chemical derivation
Acetyl-L-carnitine is an acetylated derivative of L-carnitine. L-Carnitine is derived from the amino acids lysine and methionine.
Health claims
ALCAR supplementation has been shown to be neuroprotective in instances of cerebral ischemia in rats[2] and may be useful in treating peripheral nerve injury.[3] It may have some neuroprotective benefit in the treatment of Parkinson's disease, but further research is required.[4] Research into the compound's safety and efficacy in humans is required. ALC has been shown to be more effective than tamoxifen in improving the curvature and reducing the pain and plaque sizes for men who sought treatment for their Peyronie's disease early and having low curvature deformities.[5]
