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.

Quite literally a godsend!

In January I was diagnosed with myasthenia gravis. My symptoms were muscle weakness in the extremities, double vision, drooping eyelids, terrible headaches, eye pain, pain all over my body as well. Suffice it to say, the double vision hampered my independence and I wasn't able to drive. I had read information on Huperzine A and that one of its uses was for myasthenia gravis. I didn't want to take drugs that were usually prescribed for this autoimmune disease especially after reading all the side effects they cause so I tried Huperzine A. My double vision was gone within minutes of taking my first dose. I now take 200 mcg./day. I'm also pleased to say that I can now safely drive again! One caveat however, you may find that the huperzine A efficacity wears off after a while, the remedy to that is to cycle it. The body builds a tolerance to it. Take the supplement for 3 weeks and stay off it for 1 week, then start up again. In my case, as it accumulates in the body, I found that the double vision didn't come back even during the week I was off it. I'm extremely pleased with this product and the price is reasonable as well.

I've seen improvements

This is the first type of Huperzine A produce I've tried and I honestly believe, for the price, is worth it. My memory has improved which is the sole reason for taking this. I usually take 1 before bed, I'm currently trying to have 2 split up AM PM, so far there's been no difference in effect. I'll be purchasing these again once I run out.

Provides mental clarity but you would need to stick to the recommended dose and never even exceed it!

Posted by 4817297259088007077 on Dec 03, 2016 | Verified Purchase

The product is effective, but the side effects could be serious if you don't follow instructions. I didn't feel well at all when I exceeded the recommended dose. Never ever exceed the dose! It's NOT one of those "natural" supplements when you safely go over recommended dose... After that negative experience - I stopped using it
