Good preparation, a small dosage. I plan to take to improve memory concentrating under intensive training loads. DMAE, one of the most important means to prolong life. It is assumed that the extension of life based on the following effects from the use of DMAE: 1) DMAE when ingested converted into acetylcholine. In the body, there is one of the most important substances - acetylcholine. This neurotransmitter or neurohormone responsible for regulation and transfer signals from one nerve cell to another, both in the brain and throughout the CNS. That is, it makes our body acetylcholine one. Lack degrades acetylcholine adjustment and the whole body - actually the body decomposes faster than usual. Note that up to 75% of the population may have a deficiency of acetylcholine. That is, many do not even have enough to meet the physiological needs. To extend the life of acetylcholine required several times more. From a lack of acetylcholine occur: weakness, fatigue, depression, slow response, difficulty in thinking, poor memory, irritability and so on. 2. DMAE possess a pronounced antioxidant effect and inhibits the cross-linking molecules. 3. With age in brain cells, CNS, heart, skin, etc. Accumulated toxic lipofuscin pigment, which poisons the cells. Under age each cell may be at 30% packed lipofuscin. DMAE in a period of several months to 2 years, removes up to half or more of this garbage. 4. DMAE significantly improves the properties of blood; capture and transfer of oxygen to the tissues. Side effects and contraindications. Because DMAE ingredient of natural origin and is present in some foods and in the body, and the side effects are possible only in cases of extreme overdose. Press YES if my review helpful to you. Thank you!
