Product Overview


  • Dietary Supplement
  • For Learning and Memory

Huperzine A is a natural compound extracted from the Chinese club moss Huperzia serrata. Worldwide studies have shown that Huperzine A supports learning and memory by protecting acetylcholine, a neurotransmitter that acts as a messenger molecule in the brain. Huperzine A may be used for both short-term "brain boost" needs, such as preparing for a test, as well as more long-term needs, such as reducing the mild memory loss associated with normal aging.

Suggested Use

1 tablet 1 to 2 times daily.

Great stuff

Posted by 5459016201272341701 on May 16, 2017 | Verified Purchase

Great substitute for Mestinon (remedy for Myasthenia Gravis), but also good for muscle weakness or brain fog due other causes.

If taken on empty stomach, should drink a lot of water. It may cause some pain in stomach.

Wonderfull stuff, great for removing side effects of anticholinergic drugs

Posted by 5708847573405819396 on Apr 03, 2017 | Verified Purchase

I was on a pharmaceutical cholinergic for a year prior to trying Hup-A, but Hup-A actually works better, although whether it is due to the different dosage and uptake speed is debateable. Either way, it's a great product. I am on two anticholinergic drugs and use Hup-A to counter that effect (anticholinergics produce dry mouth and dry eyes, dry skin, reduced ability to sweat, alongside causing constipation and fatigue, possibly also increasing risk for Alzheimer's). Start with the 100mg tablets, or cut these guys in half with a sharp knife and start with the halves. Hup-A is serious stuff, be careful to avoid overdose (more is not better - excess acetylcholine results in nausea, vomiting, shivers, possibly seizures). I wouldn't recommend it for folks with regular acetylcholine levels for this reason. But for those with MG or on anticholinergic drugs with undesirable side effects, this stuff can be the answer to your problems, when taken safely.
