L-Carnitine's core function is to transport long-chain fatty acids into the mitochondrial matrix for β-oxidation. Since long-chain fatty acids cannot cross the inner mitochondrial membrane directly, they require the coordinated action of carnitine palmitoyltransferase I/II (CPT-I/II) and the carnitine-acylcarnitine translocase. This "fatty acid shuttle" mechanism is essential for generating energy from fat metabolism.
Acetyl-L-Carnitine (ALCAR) is the acetylated form of L-carnitine, offering unique neuroprotective benefits. As ALCAR can cross the blood-brain barrier, it exerts multiple effects in the central nervous system: enhancing acetylcholine synthesis to improve memory and cognition, supporting mitochondrial function to reduce oxidative stress, boosting nerve growth factor (NGF) expression for neural repair, and regulating glutamate metabolism to prevent excitotoxicity.
Clinical studies show that daily supplementation of 1-2g ALCAR for 3-6 months significantly improves cognitive function (memory, attention, executive function), reduces depressive symptoms, and alleviates pain and numbness associated with diabetic peripheral neuropathy. Due to its neuroprotective effects, ALCAR is a key ingredient in functional medicine for supporting emotional and cognitive brain health.
In functional medicine product development, ALCAR is a key ingredient in the Mitochondrial Energy Complex of the Energy & Mitochondrial Series (ALCAR + CoQ10 Ubiquinol + PQQ + NADH). It is also used in the Mind-Body Resilience Series for daytime cognitive support and relaxation formulas. Dynas Group Hong Kong supports custom capsule and powder formulations.
