A derivative of the supplement Carnitine, Acetyl L-Carnitine (also known as ALCAR) acts as a different form of enhancer due to its impact on a user’s mental state rather than their physical capabilities. Its greater bioavailability (ability to enter efficiently into the bloodstream and reach the brain) separates itself from L-Carnitine, and once it does it breaks down into a compound called Acetyl-COA to combine with choline. This forms the powerful neurotransmitter Acetylcholine.



After reaching the brain and combining with the compound choline, Acetyl L-Carnitine helps to create the powerful neurotransmitter Acetylcholine, which is essential in boosting the synaptic processes found within the central nervous system. However, this process cannot take place without appropriate levels of choline already established in the body, which ensures that ALCAR cannot be considered a direct precursor to Acetylcholine. It is only a supplement that assists in the increased production of that crucial neurotransmitter. The benefits of a higher level of Acetylcholine include an improvement in the creation and recall of long-term memory, reasoning abilities, and mental clarity. In addition, ALCAR acts as a potent antioxidant that can help to remove harmful toxins from the brain, ensuring the possibility of neural maintenance and elevated brain health.

Side Effects

ALCAR can be produced naturally by the human body, a fact that makes it a generally safe compound when consumed for the purpose of cognitive enhancement. There are mild side effects that can be recognized in the form of headaches, stomach pains, nausea, and diarrhea. Rare side effects come in the forms of rancid body odors and
unpleasant breath. It is advised for those pregnant and/or breastfeeding, as well as those with a history of seizures, to consult a qualified physician for more clarification on their eligibility to use ALCAR.


Average doses of ALCAR are recorded to be in the realm of 500-1000 mg. Doses are advised to be taken two to three times daily. Despite the fact that this supplement has cognitive benefits when taken on its own, taking ALCAR with supplements classified as choline sources such as Alpha GPC or Citicoline will boost its effects.
