Huperzine A Benefits
Huperzine A is a natural nootropic supplement, derived from the Chinese club moss. Huperzia Serrata is known for its ability as a neuroprotectant. Huperzine A is shown to increase levels of acetylcholine and dopamine, which can improve your concentration, memory, and learning. Research shows that increasing acetylcholine levels can also reverse normal signs of cognitive decline that results from aging.
Huperzine A Dosage
Standard dose of Huperzine-A tends to range from 50-200mcg daily. Supplementation of huperzine-A does not require food, however it is recommended that this supplement is cycled on and off of, as it has a relatively long half-life.
Huperzine A 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.
Huperzine A Toxicity
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.
