Huperzine-A is a compound extracted from the herbs of the Huperziceae family. It is essentially an acetylcholinesterase inhibitor – it prevents that enzyme from breaking down acetylcholine, thus increasing the amount of this neurotransmitter.

Huperzine-A supports brain cell mitochondria, protecting them from free radical damage by acting as an antioxidant. It also bolsters neuron resistance to beta-amyloid induced dysfunction that could potentially lead to neurodegenerative diseases. Moreover, by acting as an NMDA receptor antagonist, it prevents glutamate excitotoxicity which has been associated with brain cell degeneration. Huperzine A also boosts the synthesis of NGF (nerve growth factor) which plays a critical role in brain cell development, maintenance and repair.

Products that combine huperzine A with certain drugs used for treating Alzheimer’s disease are being studied for their efficacy, as they might potentially have comparable therapeutic benefits at lower doses and, therefore, cause fewer side effects.

Huperzine A is often used by patients with Myasthenia Gravis.

Based on animal and human studies, huperzine A can be considered safe. It is generally well tolerated, with rarely any side effects at dosages routinely supplemented with.

Benefits of taking huperzine A

  • increased learning capacity;
  • improved attention and alertness;
  • maintaining the healthy functioning of the brain;
  • improved memory and recall;
  • enhanced, stable mood;
  • supporting memory and cognitive performance during aging;
  • mild, clear-headed stimulation;
  • lucid dreaming.

Side effects

Huperzine A can be toxic when used above the recommended dose range, or in individuals with high acetylcholine levels.

Side effects of huperzine A are rare, but they resemble the symptoms of choline overload.

  • nausea;
  • nasal obstruction;
  • hyperactivity;
  • vomiting;
  • diarrhea;
  • insomnia;
  • anxiety;
  • dizziness;
  • constipation;
  • thirst;
  • cardiac arrhythmia (very rarely).

Symptoms of acute toxicity are listed below

  • muscle tremors;
  • drooling;
  • tears;
  • bronchial mucous;
  • incontinence.


  • epilepsy;
  • asthma;
  • emphysema;
  • urinary tract or reproductive system blockage.

Those suffering from heart disease as well as those who take drugs used for treating Alzheimer’s disease should consult their doctor before using Huperzine A.

Popular nootropic supplements NAC and NACET possess acetylcholinesterase inhibitor properties, so their concomitant use requires special caution, and perhaps a dosage adjustment.


Huperzine A is taken orally, and the standard dose is 200 mcg.

It has a half-life of 10-14 hours, while some of its effects last much longer, which is why it is advised to cycle it. One can choose to either take it every 2nd day, or twice a week.
