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 acetylcholine. Supplementing with Acetyl L-Carnitine may improve acetylcholine production and stimulation of protein and membrane phospholipid synthesis.
 •Acetyl L-Carnitine facilitates the metabolism of fatty acids for energy generation. A greater reliance on fat for energy can result in a sparing of muscle glycogen, an enhancement of exercise performance and a reduction in stored body fat. Acetyl L-Carnitine has profound effects on endurance and exercise performance by reducing the respiratory exchange ratio and reducing lactic acid accumulation in muscles extending exercise capacity before fatigue.
 •Carnitine comes in both L- and D-carnitine forms. However, only the L- form is biologically active. The D- form is completely inactive and in large quantities and particular conditions, the D- form may inhibit the utilization of L-carnitine. NutraBio L-Carnitine supplements contain no synthetic D-Carnitine or DL-Carnitine. D-Carnitine and DL-Carnitine are less effective than L-Carnitine. D-Carnitine and DL-Carnitine are not recommended because of their adverse physical side effects.
