Acetyl L Carnitine is a supplement to help people burn unwanted or excess body fat. Acetyl L-Carnitine, also known simply as L-Carnitine, transports fatty acids across the inner mitochondra membrane where they are burned and used as energy. Without acetyl L-Carnitine, fatty acids pile up, leading to weight gain. L-Carnitine also helps enhance memory; some people take it to help combat Alzheimer's disease. Certain foods including meats, vegetables and fish contain this supplement.
Both red meat and pork contain acetyl L-Carnitine. Red meat contains a higher concentration of the supplement than white meat. A 3 oz. beef steak contains 81 mg of L-Carnitine. Ground beef contains about 80 mg, but white meats contain little to no concentration of L-Carnitine, although pork contains 24 mg.
The concentrations of acetyl L-Carnitine in fish and poultry are not as high as red meat. A 3 oz. piece of cod contains 5 mg. A 3 oz. piece of chicken breast only contains 3 mg.
Dairy products contain some L-Carnitine, but not as much as meat. One cup of milk contains 8 mg of the supplement, a 1/2 c. of ice cream contains 3 mg, a slice of American cheese contains 1 mg.
Vegetables contain the least amount of acetyl L-Carnitine. For example, mushrooms contain 2.6 mg, and carrots only contain 0.4mg. One medium avocado contains 2 mg of L-Carnitine.
You body produces some acetyl L-Carnitine, but the amount is small. The supplement is found in the heart and skeletal muscles. Deficiencies of the supplement include muscle fatigue and cramping.
