Acetyl L-Carnitine is a powerful amino acid that supports both mental clarity and physical energy. In the brain, it helps boost the production of acetylcholine—a key neurotransmitter for memory, focus, and learning—while also protecting brain cells from oxidative stress. In the body, ALCAR helps convert fat into energy, supporting cellular metabolism, endurance, and recovery. It’s especially valued for promoting sharp thinking, reducing mental fatigue, and improving physical performance—all from one highly absorbable, brain-friendly form of carnitine.
