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.

My mom has Alzheimer’s disease; she is in the late stages. She would not eat, drink or talk; she sat in a blank stair. She has been taking Source Naturals, Huperzine A, for over a year. She started back eating (must be fed), drinking and talking again. I done expect her to be healed but I thank God that the disease process was slowed down and I can continue to enjoy the company of my mother. I can only wonder what the effect would have been if I had known about it when my mom first started to have symptoms.

No better choline source
I find I react better to inhibitors than precursors. Huperzine inhibits the chemical that breaks down choline, so that you have more choline to use. This is similar to the way SSRIs inhibit the chemical that breaks down serotonin. DO NOT USE huperzine with a choline precursor, such as CDP-choline (citicoline), choline citrate, DMAE, etc. This will result in an overload of choline in the brain, which will have unknown effects but at the very least will give you brain fog and have many of the opposite of the intended effects. For me it takes 3 days or so for this to really kick in. For most it takes only a few hours. If you aren't getting good results from this after a week, it isn't for you. Try CDP-Choline, or perhaps a difference avenue of cognitive enhancement other than choline increase.
