Maximum Strength Amino Acids.   Acetyl l-carnitine is an amino acid, made from l-carnitine. However, it is not a building block amino acid for protein production in the body, although is has other important roles. Acetyl L-carnitine  is created in the brain, liver, and kidneys from carnitine. While traditional l-carnitine is used for fat metabolism and athletic performance, acetyl l-carnitine can play an additional role.    Both l-carnitine and acetyl l-carnitine are antioxidants and can assist in protecting against undesirable free radical activities. Also, carnitine is critical for supporting the efficient use of fat for energy in cells through the body. Acetyl L-Carnitine can be converted to carnitine based on the needs of the cell. However, but the focus of acetyl l-carnitine is more on cognitive support*. Acetyl l-carnitine is often used to help support memory, mental focus, and overall mood by supporting the formation of neurotransmitters. * Neurotransmitters help maintain proper brain function. *   Support brain functions including memory, focus, and mood* Help formation of neurotransmitters in the brain* Assist in converting food to energy* Antioxidant properties that can help protect cells from oxidative stress* Rapid release
