I am having a problem with my memory . I am 73 yrs old and find in the morning my mind is foggy, I sometimes get confused and forgetful. I used to have a very good memory. I just bought a vitamin by Natrol called brain spped memory. Contains 50 MG thiamin, 125 mg niacin , 10MG B6,1,000 MG folic acid , 500 MG B12,125 pantothenic acid . My doctor does not believe in natural medications. What do you think?
