Best Huperzine A Supplements 2026
Huperzine A is a naturally occurring alkaloid extracted from Chinese club moss (Huperzia serrata). It works primarily by inhibiting acetylcholinesterase — the enzyme that breaks down acetylcholine — thereby increasing levels of this key learning and memory neurotransmitter. It is one of the most well-studied natural nootropics for cognitive enhancement and has been used in China to treat Alzheimer's disease.
