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.

Inconsistent product

Posted by 5477134530709370979 on Apr 28, 2016

I bought this product twice and the second batch looked and tasted nothing like the first one and I am not sure their effectiveness whereas strong either as the first batch. It's hard to believe that it's even the same product. Even in the first order I felt like there was a discrepancy in effectiveness from pill to pill.

So i've been taking these things for about 2 weeks now, and i'm starting to notice the effect it's having, so far there have been no side effects whatsoever and i'm feeling great, if anything my appetite has increased after using it. The best effect for me is when i take one right after waking and one right before going to sleep, it's said that it has a half life of 8-12 hours, so that way it's always working around the clock. The effect is unbelievable really, i started learning a new subject, quite deep learning curve and complex, about a week ago that has so far included hours of material and i practically remember all of it down to details. I would recommend it for recreational use.

i could really feel the effects of this product within a very short period of time brain i took down one start cause of one negative effect the on the brain gave me very vivid dreams (which were easier to remember also) but made it difficult to sleep properly(harder to fall asleep and easy to be woken up) but after i started to break the pills in half this side effect seem to be lessen the company to really consider making the pills smaller
