Acetyl L-Carnitine is a molecule that occurs naturally in the brain, liver and kidney and diminish as we age. Some of the primary used of acetyl L-Carnitine are as follows: May Enhance cognition. Involved in the metabolism of food into energy. Reports indicate that Acetyl L-Carnitine may be effective in the treatment of dementia. May improve visual memory and attention. May reduce severity of depressive symptoms in the elderly. May improve both spatial and temporal memory, and reduce the amount of oxidative damage to RNA in the brain's hippocampus, an area important in memory. Acetyl L-Carnitine is a stabilized and more absorbable form of the amino acid L-Carnitine. Acetyl L-Carnitine plays an important role in protecting and supporting brain and muscle function. As an antioxidant, Acetyl L-Carnitine protects neurons from damage caused by superoxide radicals. Acetyl L-Carnitine is involved in aspects of neuronal metabolism because its molecular structure resembles the neurotransmitter
