Huperzine A is a natural nootropic supplement that is known for its ability as a neuroprotectant. Huperzine A promotes healthy memory and cognitive ability.
Standard dose of Huperzine-A tends to range from 50-200mcg daily.
Mode of Action
Huperzine A is derived from the plant Huperzia Serrata, it is a natural acetylcholinesterase inhibitor. Acetylcholinesterase is responsible for the breakdown of the neurotransmitter acetylcholine, therefore by and so by inhibiting acetylcholinesterase, more acetylcholine is available to the brain. This in turn, promotes better overall cognitive function and memory.
Research shows the LD50 (dose needed to acutely kill half a population of rats) was 2-4mg per kg bodyweight in females and 4mg/kg in males. There is currently no toxicity data for humans.
