乙酰基-左旋肉鹼能影響大腦中乙酰膽鹼的水平，乙酰膽鹼是腦部主要負責記憶和適當腦功能的神經遞質。乙酰基-左旋肉鹼也能影響神經元水平，促進其合成和增強其功能。乙酰基-左旋肉鹼更能促進神經元釋放更多多巴胺(一種神經遞質），並幫助它粘合多巴胺受體，從而發揮重要功效。
大腦衰老過程中，合成和利用乙酰膽鹼和多巴胺的能力都明顯減弱。補充乙酰基-左旋肉鹼能有效延緩腦退化。研究人員還發現，乙酰基-左旋肉鹼能進一步作為大腦內的一種抗氧化劑，穩定細胞膜，並增強腦細胞內的能源生產。
Many authorities point out that acetyl-L-carnitine more readily crosses the blood-brain barrier than do other forms of L-carnitine. This is one explanation sometimes given for the greater activity found with acetyl-L-carnitine than with other forms of L-carnitine in conditions involving the brain.
Acetyl-L-carnitine influences neuronal levels of acetylcholine, a major neurotransmitter responsible for memory and proper brain function, but supporting its synthesis and functions. Acetyl-L-carnitine also enhances the release of dopamine from neurons and helps it bind to dopamine receptors.
As the brain ages, the ability to synthesize and utilize acetylcholine and dopamine declines. Researchers have discovered that acetyl-L-carnitine further acts as an antioxidant within the brain, that is stabilizes cell membranes, and enhances energy production within brain cells.
