Acetyl-L-carnitine capsules contain 500 mg of pure acetyl-L-carnitine. Acetyl-L-carnitine plays a key role in maintaining normal brain and nerve function during the normal aging process. In most tissues of the body, both L-carnitine and acetyl-L carnitine are involved in fatty acid oxidation. The activity of this important enzyme has a tendency to decline during the normal aging process, causing low acetylcholine levels which in turn, are thought to contribute to the impairment of brain function that is associated with aging. Besides maintaining normal acetylcholine levels, several studies indicate other neuroprotective benefits of acetyl-L-carnitine.
Acetyl-L-carnitine has been shown to maintain cellular membrane stability, and to restore age-related membranal changes. Acetyl-Lcarnitine can also act as an antioxidant, scavenging harmful superoxide radicals. Acetyl-Lcarnitine preserves normal levels of nerve growth factor in brain tissue during aging.
Human studies showed up to 3 grams of supplemental acetyl-L-carnitine supports normal brain and nerve function during the normal aging process through various mechanisms. These include its actions on acetylcholine synthesis, membrane stability and nerve growth factor production. Acetyl-L-carnitine capsules may be a useful nutritional adjunct for individuals who wish to support the body’s nervous system and brain function.
