Huperzine A is a phytonutrient that helps maintain proper memory function. It does this by slowing the breakdown of acetylcholine, a process that accelerates with aging. Acetylcholine plays a vital role in the cognitive function of the mind by enabling the delivery of messages from neuron to neuron in your brain. When there is too much Acetylcholine, it accumulates in the body. You may either have too much acetylcholine or too little. The more common problem is a deficiency, and diminished brain processing speed, but there are symptoms for each.
Too much can produce feelings of paranoia, and you can feel as though you are being taken advantage of.
Too little, and you can develop Alzheimer's symptoms. I will do some research for you, unless somebody else can answer this. I take HGHup 5 on, 2 off. i know the bottles doesnt say that, but thats how ive always dosed HGHup
