Pharmacology Action: Huperzine A may have cognition-enhancing activity, can maintains acetylcholine levels for healthy cognitive function and promotes enhanced memory and cell to cell communication, it is potentially ward off the devastating effect of the memory-robbing disease Alzheimer' s.
Dosage: Huperzine A is a highly potent compound with a recommended dose of only 100 to 200 micrograms twice a day for age-related memory loss. We recommend using it only under a doctor' s supervision.
Safety Issues: Perhaps because it works so specifically, huperzine A appears to have few side effects. However, children, pregnant or nursing women, or those with high blood pressure or severe liver or kidney disease should not take huperzine A except on a doctor' s recommendation. We also don' t know for sure whether huperzine A interacts adversely with any drugs; however, it seems likely that huperzine might interact with drugs that function in a similar fashion ( such as standard drugs for Alzheimer' s Disease) .
