ALCA™ 500 combines the amino acids Acetyl-L-Carnitine and L-Arginine in a unique molecular structure to form Acetyl-L-Carnitine Arginate. Acetyl L-Carnitine (also known as Acetylcarnitine, acetyl L-carnitine, acetyl L-carnitine, or L-acetylcarnitine) is a form of L-Carnitine, but more bioavailable. Acetyl L-Carnitine transports nutrients into cells that are necessary for energy production, yielding the energy molecule ATP. Similarly, the acetyl group of acetyl L-carnitine aids in the formation of acetyl-CoA, a very important link in processing energy from amino acids, fats, and carbohydrates, and is used to make the necessary brain chemical acetylcholine. As an antioxidant, Acetyl-L-Carnitine protects neurons from damage caused by superoxide radicals.

L-arginine helps rid the body of ammonia and is used to make compounds in the body such creatine, L-glutamate, and L-proline. L-arginine can be converted to glucose and glycogen. L-arginine is also used to make the nitric oxide, a compound in the body that relaxes blood vessels and aids circulation.

Suggested Use: Take 1 to 2 capsules per day, or as directed by your qualified health care consultant.

Notes: ALCA™ 500 contains Acetyl-L-Carnitine Arginate, a novel molecular combination of the amino acids Acetyl-L-Carnitine and L-Arginine. Acetyl-L-Carnitine is a more bioavailable form of L-carnitine, an amino acid found in high concentrations in human brain, nerve, heart, liver and sperm cells. Acetyl-L-Carnitine supports energy production, participating in metabolizing fatty acids to yield the energy molecule ATP in the mitochondria.* As an antioxidant, Acetyl-L-Carnitine protects neurons from damage caused by the corrosive superoxide radical.* L-Arginine is utilized to produce nitric oxide, an important compound involved in circulation, and creatine, a compound needed to regenerate ATP stores.* Store in a cool, dry place. Do not refrigerate.

Other Ingredients: Cellulose, magnesium stearate (vegetable source) and silicon dioxide. Capsule consists of gelatin. No wheat, no gluten, no soy, no dairy, no egg, no fish/shellfish, no nuts/tree nuts.
