Acetyl-L-Carnitine - Improves energy levels, enhances and maintains memory and supports heart health

Acetyl-L-Carnitine is a form of carnitine that can effectively help improve and maintain memory and enhance heart health. It improves overall energy levels, as well as improving mental focus, learning, mood, and cognitive function. It promotes eye and vision health and speeds up recovery time from exercise. It guards against oxidative stress and neurotoxicity, together with improving mitochondrial function and structure.

Carnitine is an amino acid that carries fuel into the mitochondria of every cell for energy production (adenosine triphosphate - ATP). Acetyl-L-carnitine is the acetylated ester form of L-carnitine and both are easily and efficiently absorbed into the bloodstream but, it is the processed form of carnitine, Acetyl-L-carnitine, that is able to cross the blood-brain-barrier (BBB) to help energise the brain, protect against neurotoxicity and oxidative damage that is so associated with ageing and disease.

L-carnitine is widely used by people who lead a high-active and demanding lifestyle and include sport and exercise into their weekly regime.

Acetyl-L-carnitine provides support for the nervous system, cardiovascular system and muscle. It is needed for the transport of long-chain fatty acids into the heart of the cells, for the production of cellular energy (ATP). Acetyl-L-carnitine may help prevent DNA degeneration and promote DNA repair from mutations that can occur from free radical production. It is the form of carnitine that has been seen to effectively maintain memory and assist in recovery from a stroke.

Carnitine is manufactured from lysine (an essential amino acid - lysine helps the body produce antibodies, hormones, and enzymes), and methionine (an essential amino acid) in the liver, kidneys and brain.

Vitamin C, Iron, niacin (vitamin B3) folic acid (vitamin B9) and vitamin B12 (cobalamin) are also essential for the manufacture of carnitine.  


  • Most amino acids come in two forms; D- or L- (such as L-tyrosine or D-tyrosine). D-amino acid is a mirror image of the L- amino acid - in other words the D- form is a backward image.
  • Both can be taken. However, the L- form is preferable as it is the exact image of the amino acid in its natural form found in the body. The L- form is considered the more effective for overall human health. 

As with most amino acid supplements your body needs vitamin B6 (pyridoxine) as a cofactor to ensure correct amino acid metabolism.

As a dietary supplement, adults take one capsule daily. Take 30 minutes before a meal with a glass of water for best results, or as directed by a healthcare professional.

Store in a cool, dry place, away from direct light.

Do not exceed the recommended daily dose.

Keep out of reach of young children.

Children, pregnant women, and women who are breastfeeding should consult their doctor before use.

Nutritional supplements should not replace a varied and balanced diet and a healthy lifestyle.

Check with simultaneous intake of medicines with your physician or healthcare professional. No long-term use without professional advice.


If you have kidney or liver disease, please contact your doctor before starting a carnitine supplementation.
