I was little skeptical when I read the product description which says supports the myelin sheath which surrounds certain nerve tissues. I don’t understand the meaning of the words certain nerve tissues. I think there is nothing bad about ingredients in and of themselves. And I think anything a person does to support health in body is good. Itâs my personal take on and I want to know what the meaning of this particular phrase is? It will be really nice if anyone can help me to find its description.
