Additional Information

Acetyl-L-Carnitine (ALC) is a stabilized and more bioavailable form of the amino acid L-Carnitine and is utilized in many metabolic functions. ALC plays an important role in the transfer and utilization of long-chain fatty acids for the production of energy. As an antioxidant, ALC can protect neurons from damage caused by superoxide radicals. ALC is involved in other aspects of neuronal metabolism and may improve cognitive function and reduce the symptoms of depression in the elderly. Since levels of this nutrients decline with age, supplementation is the key to receive adequate amounts.
