Huperzine A

Описание

Huperzine A is an alkaloid extract derived from the Chinese club moss Huperzia serrata. It is an acetylcholinesterase inhibitor. This means it helps promote higher levels of acetylcholine in the brain. Higher levels of acetylcholine support ones ability to perform cognitive tasks such as learning new things, memorizing information, and focusing at the task at hand. Huperzine A is considered to be a nootropic supplement because it supports cognitive function. It is considered a focus and memory nootropic similar to alpha gpc, bacopa, phosphatidylcholine, cdp choline, sulbutiamine, and uridine. It is also considered a brain booster as it is used for brain health and support.
Huperzine A for many years has been widely used in traditional Chinese medicine to enhance memory and to treat fever and inflammation. In the United States it is commercially available as a food supplement, but has not been approved by the FDA as a treatment for AD or other cognition disorders.

преимущество

Huperzine A can help support learning and memory by protecting acetylcholine, a neurotransmitter that acts as a messenger molecule in the brain. Huperzine A may be used for both short-term "brain boost" needs, such as preparing for a test, as well as more long-term needs, such as reducing the mild memory loss associated with normal aging.
ACETYLCHOLINESTERASE INHIBITOR - Huperzine A acts as a reversible Acetylcholinesterase inhibitor meaning it supports levels of the neurotransmitter acetylcholine which plays a key role in cognitive function.
SUPPORTS COGNITIVE FUNCTION - Supports working memory, motivation, and problem solving ability.
SUPPORTS ENERGY AND STAMINA - Huperzine A supports mental energy, stamina, and sustained focus.

Способ действия

Huperzine A is a reversible acetycholinesterase inhibitor that can cross the blood-brain barrier. This constituent can inhibit the activity of acetycholinesterase in the brain for several hours, which allows for increased levels of acetylcholine in different areas of the brain. Because of its effects on acetylcholine, Huperzine A is considered a beneficial therapuetic agent in the treatment of memory impairment, myasthenia gravis, and dementia.
