Acetyl L-Carnitine — 1,000 mg, 100 Capsules
Acetyl L-Carnitine — 1,000 mg, 100 Capsules — Supports Brain & Nerve Cell Function*
Acetyl L-Carnitine (ALCAR) is an acetylated form of L-carnitine that crosses the blood-brain barrier and is studied in humans for cognitive support, nerve health, and energy metabolism. It helps shuttle fatty acids into mitochondria for cellular energy and supports antioxidant defenses. Produced in FDA-registered, GMP-certified facilities and
3rd-party tested for purity & potency.*
