Huperzine A is a compound extracted from Huperziceae herbs, and is known as a potent acetylcholinesterase inhibitor. When taken, Huperzine A increases relative levels of acetylcholine by inhibiting enzymes that cause it's degradation.
Acetylcholine plays an important role in many cognitive processes including memory, intelligence, and mood. Higher acetylcholine levels have been shown to improve cognitive performance.
Huperzine A supplementation tends to be in the range of 50 - 200 mcg daily. Our tablets are 200 mcg each, but can be easily broken into halves or quarters for those wishing to take smaller doses.
Huperzine A has a long half-life (10-14 hours), so cycling this product is often recommended. Usually a Huperzine A cycle lasts between 2-4 weeks, with a break of 1 week between each cycle.
When taken at recommended doses Huperzine A is well tolerated and presents few side effects. Rarely, side effects including nausea, diarrhea, and loss of appetite may occur. Adverse side effects are more likely when exceeding the recommended dosage.
Huperzine A is not recommended for people suffering from heart conditions, consult your physician before taking this product
