My doc put me on foilc a few weeks ago i don't feel any different but when she had done my last blood work up it came back that i was really low on that and being so inactive i now have to take cholesterol pills. But when i asked about the foilc she said that it helps the nerves heel. Until then i never heard of this i knew that pregnant woman need it but did not know why. As far as vitamins go the only time i take them is when i don't eat right which has been a lot because of my depression. But i also believe that one can overdose with all these vitamins and supplements. But i wonder why they help some and not others?
