What is Huperzine A? Huperzine A is a natural alkaloid compound that is purified and extracted from the green moss known as Huperzia serrate. It is a natural nootropic that has been used in traditional Chinese medicine as an herbal supplement for hundreds of years. Huperzine A is known as an acetylcholinesterase inhibitor. This means that it works to stop an enzyme from breaking down acetylcholine in the brain. It is also known for its neuroprotectant abilities, especially relating to memory enhancement and protection from cognitive decline. How does Huperzine A work? Huperzine A works as an acetylcholinesterase inhibitor, blocking cholinesterase from breaking down acetylcholine in the brain. The result of this is increased levels of acetylcholine in the brain. Acetylcholine (ACh) is a vastly important neurotransmitter neurotransmitter in the brain responsible for half of the nerve messages sent along the parasympathetic nerve system. It controls all of the neuromuscular (brain-to-skeletal muscle) nerve connections and It is also required for proper memory function and cognition. High acetylcholine levels ultimately lead to greatly enhanced memory and cognitive function. Huperzine A also promotes neurogenesis–the birth of new neurons in the brain–and acts as a neuroprotective agent as well–protecting neurons that are already in the brain from damage. Why use Huperzine A? Improves memory Protects against decline in memory caused by aging Promotes neurogenesis Boosts acetylcholine levels Improves information retention Improves studying ability Inhibits Somatostatin in the body, resulting in greater HGH levels in the body, which have a multitude of benefits for body composition and anti-aging How to use Huperzine A? Huperzine A works best for most individuals at dosages between 50-200mcg. It also stacks very well with other nootropics such as AlphaSize and Vinpocetine (All 3 are main ingredients in Red Focus). Taking Huperzine A in combination with AlphaSize can increase the amount of acetylcholine in the brain, which greatly enhances the effects of Huperzine A. Classes of Huperzine A Huperzine A is also known as Selagine. Possible Side Effects of Huperzine A Huperzine A is considered safe to use and is generally well tolerated. On rare occasions, Huperzine A can cause an upset stomach, nausea, vomiting and diarrhea, but this is typically the result of taking too high of a dose. Huperzine A can cause the heart to slow down and affect blood pressure, so individuals with heart disease should use it cautiously.
