What is Huperzine A?

Huperzia serrata (synonym Lycopodium serratum) is a species of fir clubmoss that has been used in Traditional Chinese

Medicine (as Qian Ceng Ta). Huperzia serrata has several bioactive compounds, including lycopodium alkaloids, triterpenes,

flavones and phenolic acids. The most important and widely studied of these is the alkaloid huperzine A, which indirectly

supports healthy acetylcholine levels in the brain. Acetylcholine is a neurotransmitter and neuromodulator that plays important

roles in cognitive function, most notably, in the neural mechanisms of memory [1], but also in executive function, alertness,

attention, and learning. Acetylcholine supports different types of memory, from working memory to long-term memory,

and different phases of memory, from memory formation to consolidation and retrieval. By supporting acetylcholine

signaling, huperzine A supports cognitive function. Huperzine A has also been shown to support brain antioxidant defenses

and neuroprotective functions.
