Allergy Research Group Acetyl L-Carnitine 250mg 60c is -an acetyl derivative of the amino acid carnitine, and a naturally occurring metabolite. Taken orally it crosses the blood-brain barrier more readily than does carnitine and supports energetics and homestasis. The acetyl derivative of L-carnitine. Like L-carnitine, acetyl-L-carnitine is involved in the metabolism of protein, carbohydrates and fats, as well as the conversion of fats into energy and triglyceride metabolism. Acetyl-L-carnitine crosses the blood brain barrier more readily than L-carnitine, has antioxidant properties, and because it has an affinity for nerve cells, may especially provide antioxidant protection for neuronal integrity. Acetyl-L-carnitine supplementation has been shown to support glutathione and CoQ10 levels. It mimics acetylcholine and therefore may positively affect the brain chemistry involved with memory and moods, as well as energy production in the brain. Free form amino acid, high purity, well tolerated.
