[3]What exactly about this alkaloid is piquing the interest of researchers?Well, in the case of treating Alzheimer’s disease, the compound works by inhibiting acetylcholine esterase – an enzyme that degrades the neurotransmitter. This action, however, is reversible. Through this very mechanism, the alkaloid is also able to block the signaling of Nuclear Factor- kβ. The end result is a reduction in inflammation; hence the anti-inflammatory properties of Chinese club moss.

How to take Huperzine A

Despite the extensive laboratory manipulation resulting in Huperzine A being a highly purified compound, it is considered a dietary supplement in the States. If you want to improve the memory of adolescents, you need to administer 100 mcg of the supplement twice a day. On the other hand, if you are combating senility or presenile dementia, administer 30 mcg twice a day. In the case of using Huperzine A to treat Alzheimer’s disease, the dose can be between 50 to 200 mcg twice daily. All this is via the oral route and it does not need one to take with food. This is because the compound is readily absorbed from the stomach into the bloodstream. Huperzine A is also of interest in the treatment of myasthenia gravis. In such a case, the supplement is given as a shot directly into the muscle.

Huperzine A Side Effects

As I already mentioned earlier, Huperzine A is a fairly safe nootropic supplement when compared to others with a similar goal. However, that is not to say that it does not bring with it a number of side effects, including:· Upset of the gastrointestinal tract· Headaches· Nausea· Slowed heart rateThese are symptoms that are commonplace with continued cholinergic stimulation.

Huperzine A feedback and reviews

Plenty of people have used Huperzine A. I have collated some of the feedback they had on their experience with the supplement. “I have been using Huperzine A for about one month. I only take 50 mcg every other day and I have noticed very significant increase in focus, thought process and energy while having no negative effects. I noticed the effect after the first dose and have continued to experience improvement. I believe if you do not notice any changes when taking this product then you don't have acetylcholine deficiency and do not need it but if you do notice changes then you likely have a deficiency”“I have used hup A for 2 months taking one capsule per day. I felt my memory had improved considerably and brain fog had lifted. My self-confidence had returned. Then I ran out and have had difficulty finding it in stores. In the meantime I have experienced once again searching for words. I will have to order it online or go out of town to buy since it seems the stores in the area aren't selling it. ”“I have noticed a somewhat improved cognitive function but also noticed increase in energy”“It works instantly for me. Probably depends if acetylcholine is the problem. Brain fog vanishes, dreams become vivid, memory improvement, motivation and mood improvement very noticeable on the same day.

The downside for me is it makes me so alert I am awake longer at night and it gives me a minor headache so I cut back to every other day so I get those side effects every other day. My mother and grandfather have and had Alzheimer's and I was feeling very slow tired and foggy as I neared 70 and now I am back to 30 mentally. Worth the side effects. ”
