Acetylcarnitine (ALCAR) and its Unique Benefits to Longevity and Brain Health


Last Updated on


Acetylcarnitine is the acetylated form of l-carnitine, and in this form it provides more stimulatory and nootropic effects than l-carnitine by itself. This is due to the addition of an acetyl group, which allows it to more easily to cross the blood brain barrier.

When supplemented, ALCAR is used to promote longevity and reduce the harmful effects of aging. ALCAR achieves this by supporting the mitochondria and providing neuroprotective and antioxidant effects. ALCAR is also typically used to raise energy levels – it has been shown to reduce physical and mental fatigue12, and improve anaerobic exercise performance17

ALCAR is an incredible nootropic. In many ways it is the epitome of a true nootropic: it has incredibly powerful neuroprotective qualities by preventing  damage from oxidative stress and alcohol, and can help maintain a youthful brain over time.1 It also enhances cognition 3, improves attention5, and is well-tolerated.

ALCAR also modestly increases levels of several key neurochemicals including acetylcholine, serotonin, norepinephrine, and NGF7

Most interestingly, however, is ALCAR’s ability to provide choline to the brain. While not typically thought of as cholinergic, it is able to promote acetylcholine synthesis in the brain through indirect mechanisms. This thread on LongeCity explains it extremely thoroughly and is well-cited, if you’re interested in the details.


Cholinergic mechanisms of ALCAR


In short, ALCAR is unlike other cholinergics in that it is not a precursor for acetylcholine synthesis in the brain, but instead indirectly causes high amounts of acetylcholine to be reliably synthesized. There have been numerous studies which have confirmed ALCARs ability to rapidly raise levels of ACh in the brain 20

Overall ALCAR is a very unique nootropic that can provide various mental and physical benefits, with increased energy and neuroprotection being the most significant.

ALCAR Dosage Information

The recommended ALCAR dose is 250mg to 1000mg. I would recommend you start with smaller doses and up them until you find the sweet spot, as higher doses can be less effective. I found 650 mg to be the sweet spot. ALCAR can be taken with or without meals, but is best absorbed on an empty stomach.
