Life Extension Acetyl-L-Carnitine 500mg (100 Capsules)
by Life Extension
"500mg ALCAR for mitochondrial brain energy — the acetylated carnitine that crosses the blood-brain barrier for neuroprotection and cognitive support"
Overview
Life Extension Acetyl-L-Carnitine provides 500mg of ALCAR per capsule. Unlike regular L-carnitine (which primarily supports fatty acid transport into mitochondria for energy production in muscles), the acetylated form crosses the blood-brain barrier and provides the acetyl group for acetylcholine synthesis — the neurotransmitter critical for memory and learning. ALCAR supports mitochondrial function in neurons, protecting against age-related cognitive decline. Clinical studies show benefits for mild cognitive impairment, neuropathic pain, and depression in elderly populations. The 100-capsule count provides over 3 months of daily supplementation.
