huperzine a chinese club mossHuperzine A works mainly by raising acetylcholine levels, a neurotransmitter involved with learning, memory, sleep cycle regulation, and other brain functions. Huperzine A works by the same mechanism as the popular Alzheimer’s drug Aricept.
They both work by inhibiting an enzyme (acetylcholinesterase) that deactivates acetylcholine.
Huperzine A shows promise for delaying symptoms of Alzheimer’s, especially in the early stages.
It protects the patient’s brain against free radical damage and environmental toxins while promoting new brain cell generation. Huperzine A is so powerful that it’s been given the status of an approved drug for treating vascular dementia and Alzheimer’s in China.
Huperzine A Dosage
The general recommended dosage is 50 to 200 mcg twice daily and can be taken on an empty stomach.
