  • For learning and memory

  • Supports neurotransmitters

  • 200 mcg per tablet
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 working with neurotransmitters that act as messenger molecules 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.

Rated 5 out of 5 by from Minding My P's & Q's A reliable product in my opinion. Eating lots of fruits and veggies along with exercise is also essential for we more mature people on earth.

Rated 5 out of 5 by from Terrific Service After surfing the web, I found Swanson who offered a much lower unit price than I've ever paid before, and my shipping was free. Delivery was fast. I am very pleased with this company and with this product.

Rated 5 out of 5 by from Huperzine A this is a wonderful product for us middle agers. I use this twice a day in conjunction with Acetyl L-Carnitine. Give me clarity in cognition; I notice the difference without the two.

Rated 5 out of 5 by from Huperzine A This worked for me in a week. Faster recall and short term memory definitely got remarkably better. I don't fear aging so much any more. Maintaining brain function is my goal towards a healthy retirement.

Rated 5 out of 5 by from Best Price Around If you are interested in taking Huperzine A, this is the best product available due to it's small size, high potency, and great price.

Rated 5 out of 5 by from Just chasing memories I cannot tell if these work well yet. I aced one exam and did below par on another on the same day so I'm not sure if the momory claims work. Either way, I'll be using these from now henceforth because it is about time I started taking a memory supplement with how much intense studying I have to do.

Rated 5 out of 5 by from Actually Works This is one of those supplements that's the "real deal" as far as standing up to all the claims and hype. It really does work. It brings about a nice clean alertness and I feel much more energetic when taking it. A word of caution though, if you take it too close to bedtime it can interfere with a good night's rest. For me, it caused a lot of frantic busy dreaming when I finally was able to sleep. I love to dream, but didn't like the busy feeling of the dreams this caused - it was like not getting any sleep at all.

Rated 4 out of 5 by from memory help our holistic doc recommended these. i take one each am. not sure if i've seen a definitive difference yet. maybe need some more time to build up in my system.

Rated 5 out of 5 by from Life Saver My mother's memory suffers when under stress -and this is a terrible time. A younger relative told me about Huperzine A, and the difference is night and day. I trust Swanson products, but this is one of the few items I prefer Source Naturals for; she likes the small pill form rather than Swanson capsule. On this item only, I found Swanson's didn't work as well. Thank you Swanson for the affordable price. I've tried this myself and it works. Highly recommend

Rated 5 out of 5 by from It works Used this for a few months, names and other hard to remember things came flooding back after being on this a couple of weeks. Used it all up and decided to see if anything changed, after a couple weeks off, memory was not as good. Back on it again and memory is back to very good again, am pretty sure this is the stuff that makes it happen. It is like it reconnects the brains wiring. Great price for this at Swansons.

Rated 2 out of 5 by from Didn't work for me I saw no differents after taking Huperzine A. I was hoping it would help my short term memory.

Rated 5 out of 5 by from Better Concentration This product helps me stay alert and concentrate better thrughout the day. Very good value also.

Rated 5 out of 5 by from Dramatic Improvement!! I have nearly finished my first bottle of Huperzine A. I must say that I am truly impressed with the results. I have always been able to remember faces, but not names, until now! It's incredible how easy it is to not only remember names, but to remember quotes as well! I can even hold my own with my wife in a "friendly debate" now. I love this stufff!!
