Acetyl-L-carnitine (ALCAR) is an acetylated form of L-carnitine, which is far superior to normal L-carnitine in terms of bioavailability. ALCAR is absorbed by the gastrointestinal tract, enters cells and crosses the blood-brain barrier more readily than unacetylated carnitine.
ALCAR has a broad range of uses including combination with alpha lipoic acid to comprise a patented formulation that has been evidenced to "rejuvenate" the mitochondria of aging mice in studies conducted by Bruce Ames and others. Accordingly, Acetyl-L-carnitine has potential as a life extension supplement probably capable of improving the quality and possibily also extending the average life-span of humans.
Other attributed uses for ALCAR include using it as a treatment for depression (250 mg per day for several weeks) and for clearing plaque/fatty deposits out of the veins and arteries.
