L-Huperzine A is extracted from a Chinese herb called Huperzia Serrata. L-Huperzine A inhibits the breakdown of Acetylcholinesterase that aids in raising the level of Acetylcholine, a memory neurotransmitter. It also helps in strengthening the brain’s NMDA receptors (N-methyl D-aspartate) that enhances the communication between the brain cells resulting to enhanced concentration, focus, learning and other brain functions. L-Huperzine A also stimulates the synthesis of nerve growth factor that is responsible for maintaining and promoting youthful and healthy brain function. L-Huperzine A quickly and potently boosts the memory, learning and the concentration functions of the brain for a short period of time.
