Formulation

Formula re: Contains

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.
