乙醯左旋肉鹼（ALCAR）是左旋肉鹼的乙醯化形式，與一般左旋肉鹼相似，但能穿越血腦屏障。左旋肉鹼是人體自然產生的化合物，在粒線體氧化長鏈脂肪酸的過程中扮演關鍵角色。
作為補充品使用時，ALCAR 有助於提升運動耐力與持久力，尤其適用於阻力訓練。由於 ALCAR 能穿越血腦屏障，與非乙醯化的左旋肉鹼不同，它還能支援認知功能與專注力。
Felt a noticeable lift in mental clarity within the first week of taking one capsule each morning, and the fact it crosses the blood-brain barrier makes it work faster than the regular carnitine I used to take. The energy boost is steady, not jittery, and it pairs well with my coffee routine.
The fact that this form crosses the blood-brain barrier is why I picked it over regular carnitine, and my afternoon mental clarity has been noticeably steadier since I started. Capsules are easy to swallow and I haven't had any stomach issues.
Started taking this for the brain fog that hits me mid-afternoon, and the fact that it's acetylated means it actually gets past the blood-brain barrier, which is exactly why I picked it over regular carnitine. Three weeks in, I'm noticeably sharper during my 2pm slump without feeling jittery.
