Allergy Research Acetyl-L-Carnitine is 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 bee shown to support glutathione and CoQ10 levels. It mimics aceytlcholine and therefore may positively affect the brain chemistry involved with memory and moods, as well as energy production in the brain.Allergy Research Acetyl-L-Carnitine is a free form amino acid that is high in purity and well tolerated.Suggested Use:As a dietary supplement, 1 or 2 capsules two (2) to three (3) times a daily, or as directed by a health practitioner.Amount per Serving: Acetyl-L-Carnitine (as Hydrochloride) 500mgOther ingredients:Hydroxymethylpropyl mehtylcellulose, cellulose, silicon dioxide, L-leucine.Allergy Research Acetyl-L-Carnitine is of the highest quality and purity obtainable, free of all common allergens (antigens), and does not contain preservatives, diluents, or artificial additives.Note:Please check with your Practitioner before purchasing Allergy Research or Biotics Research products
