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.

Microcrystalline cellulose, and stearic acid.

Poor Product Results

Helps me to focus

Posted by iHerb Customer on Jun 02, 2017 | Verified Purchase

I've been using Huperzine A for 2-3 weeks now. There's no drastic change but I noticed it improved my focus. I'm kind of an OC and with a slight ADD. So this really helped me focus. The downside however is that I noticed my skin kind of dried especially in the face. I can take that. I'll just use mosturizer so long as I can study well for my exams.

Thanks for your feedback!

Great stuff

Posted by iHerb Customer 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.

Thanks for your feedback!

Seems to work

Posted by iHerb Customer on Apr 25, 2017 | Verified Purchase

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