A major cause of aging is the deterioration of the energy-producing components of the cell which results in reduced cellular metabolic activity, the accumulation of cellular debris, and eventual death of the cell.*

The amino acid L-carnitine helps to maintain cellular energy metabolism by assisting in the transport of fat through the cell membrane and into the mitochondria within the cell, where these fats are oxidized to produce the cellular energy ATP.*

Acetyl-L-carnitine is the acetyl ester of the amino acid L-carnitine. Acetyl-L-carnitine is absorbed into the bloodstream more efficiently than L-carnitine, passes more easily through cell membranes, and is utilized more efficiently in the mitochondria of the cell.*

For some people, L-carnitine, especially acetyl-L-carnitine, may have a stimulating effect. Therefore, it may be unwise to take it in the evening.
