Huperzine A 1% is a naturally occurring sesquiterpene alkaloid compound found in the firmoss Huperzia serrata and in varying quantities in other food Huperzia species, including H. elmeri, H. carinat, and H. aqualupian.[3] Huperzine A has been investigated as a treatment for neurological conditions such as Alzheimer's disease, but a meta-analysis of those studies concluded that they were of poor methodological quality and the findings should be interpreted with caution.[4][5] Huperzine A 1% inhibits the breakdown of the neurotransmitter acetylcholine by the enzyme acetylcholinesterase. It is commonly available over the counter as a nutrient supplement, and is marketed as a cognitive enhancer for improving memory and concentration.

HELPING WITH MEMORY
Most people who take nootropics want to support their memory. Huperzine A might help with that objective.* In a study of teenage students, a small dose of huperzine A (50 mcg) taken twice daily for 4 weeks improved several aspects of memory and learning performance.*1 huperzine a 1% has also received significant research attention for supporting memory and cognitive performance during aging.*2 If you happen to be struggling with certain aspects of memory, or if want a little boost to pick up a new skill or learn a new subject, huperzine A may be worth investigating.*
IMPROVING ACETYLCHOLINE SIGNALING
Acetylcholine is a neurotransmitter and neuromodulator (i.e., a messenger molecule released by nerve cells to signal and regulate other nerve cells). It plays important roles in cognitive function, most notably, in the neural mechanisms of memory. In addition to this memory function, acetylcholine is involved in supporting alertness, attention, and learning.
One of huperzine A’s most recognized biological actions is its involvement in acetylcholine signaling. Huperzine A has improved acetylcholine levels in animal and human studies and influences cholinesterase enzyme activity.*3-6 The net effect is an increase in acetylcholine.* This involvement with acetylcholine signaling might explain its reported benefits on memory and cognition.*
LUCID DREAMS AND NEUROPROTECTION
Huperzine a 1% might offer other benefits. It has a reputation for increasing REM sleep (dreaming stage of sleep) and lucid dreaming*—this reputational effect has not been studied but would presumably be related to acetylcholine. The compound also has some neuroprotective qualities which are important for maintaining a healthy brain.*
1. As pharmaceutical raw materials for clearing heat, anti-inflammation, detumescence and so on, it is mainly used in pharmaceutical field;
2. As the raw material of product for benefiting stomach, increasing energy and boosting the immunity, widely used in health industry.
