What is Huperzine A?

Huperzine A is an extract of the Chinese Club Moss plant Huperzia serrata. It is an acetylcholinesterase inhibitor, which means it prevents the breakdown of acetylcholine. [1] This also means it is a cholinergic, as it supplements the amount of acetylcholine in the brain.* [2]

Huperzine A Benefits

Huperzine A’s primary benefit is as a nootropic. Its ability to supplement acetylcholine affords numerous cognitive benefits as acetylcholine is the neurotransmitter responsible for learning and memory. [3] It can also benefit focus and attention.* [4]


Huperzine A is an effective memory supplement. One study showed Huperzine A was able to benefit memory and learning performance in students complaining of memory inadequacy.* [5]

Huperzine A Dosage

Individuals should start with 8mg of Huperzine A 1% and increase up to 20mg over time. Starting with a smaller dose will allow you to assess how your body reacts to the supplement before increasing the dosage. Huperzine A is water soluble so you do not need to take it with food.
