Seed oil contains sesquiterpenes, alkaloids (celastrine, paniculatin), and polyunsaturated fatty acids that demonstrate dose-dependent cholinergic activity by inhibiting acetylcholinesterase (AChE) and increasing acetylcholine levels in hippocampal and cortical regions. Provides neuroprotection against oxidative stress through elevation of glutathione (GSH), catalase (CAT), and superoxide dismutase (SOD). Seed extracts attenuate hydrogen peroxide- and glutamate-induced excitotoxic injury in neuronal cells, and exhibit anti-inflammatory and anxiolytic properties.

Potent, selective, and reversible inhibitor of acetylcholinesterase (AChE), derived from the club moss Huperzia serrata. Exhibits preference for the tetrameric G4 form of AChE predominant in the mammalian brain. Eight-fold more potent than donepezil and two-fold more potent than rivastigmine at AChE inhibition. Crosses the BBB efficiently. Also antagonizes NMDA receptors at high concentrations and provides neuroprotection via attenuation of oxidative stress, regulation of apoptotic proteins (Bcl-2, Bax, P53, caspase-3), and upregulation of NGF.
50-200 mcg twice daily
Morning and early afternoon. With or without food.
Cycle 2-4 weeks on, 1-2 weeks off to prevent AChE downregulation
