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).
