Huperzine-A
Huperzine A does increase brain memory
Huperzine A is an extract from a club moss (Huperzia serrata) that has been used for centuries in Chinese folk medicine. Huperzine's action has been attributed to its ability to strongly inhibit acetylcholinesterase, the enzyme that breaks down acetylcholine in the synaptic cleft. Acetylcholine is involved in memory and learning. By inhibiting the enzyme that breaks it down, more acetylcholine becomes available to stimulate neurons. Alzheimer’s disease is a condition where there’s a relative shortage of acetylcholine.
Huperzine A Benefits for Mental Performance
Huperzine A works similar to some drugs used to treat Alzheimer's and Parkinson's disease (Wang et al, 2009). For this reason, it has been well studied as a potential drug to treat such neurological diseases. In healthy people, there is evidence to show that Huperzine A may improve memory and learning. When given to teenage students, Huperzine A resulted in significant improvements in memory and test scores compared to a placebo (Sun et al, 1999). Huperzine A may therefore be beneficial to those seeking a mental boost at work or school, or even for bodybuilders and athletes wanting more focus during their training.
Huperzine A Negatives & Side Effects
Because Hupersize shows promise as a treatment for Alzheimer's, its safety has been well studied in clinical trials. Compared to similar acting drugs, Huperzine A actually shows a higher degree of safety and tolerance (Wang et al, 2009). Some reported side effects include chest pain or tightness, rash, upset stomach, diarrhoea, vomiting, hyperactivity and vomiting. However, no serious side effects have been reported.
Studies done in China in 1991-1995---both using placebos and double-blind, randomized methods—found that huperzine A was effective in treating both Alzheimer’s and other memoery-degenerating conditions.Subsequent Chinese studies showed less promising effects,but a 2008 review of clinical trials conducted in that country found that,overall,huperzine A does have some beneficial effects.
