Product Overview


  • For Learning and Memory
  • Dietary Supplement

Huperzia 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.

It works, for quitting Nicotine!

Posted by Vizion on Jul 05, 2016

I am trying Huperzia Serrata to quit nicotine and still keep my acetylcholine levels high. Nicotine really helps with concentration and memory, this has a similar effect, without the addictive nature. It is shameful that the anti-smoking campaigns don't offer an acetylcholine substitute, they just tell you that there's no reason to smoke, which isn't the truth. Please like my review if this information was helpful.

Appears to work

Posted by Reviewer1260182 on May 03, 2016

I started taking Huperzine A after reading about it in a Consumerlab article on supplements that aid memory. I am 74 and and have been taking it for over two years. I feel that it boosts my short-term memory. There's no way for there to be a placebo effect in this case.

Produces vivid dreams!

Posted by 5359042171288643262 on Feb 11, 2016

By combining this with 5HTP and choline before bed, you can have incredibly vivid dreams, which really helps with attaining lucid dreams. Allegedly this also helps with memory and learning, but I have not used it for that purpose so I can't testify about that.
