My symptoms of depression get noticeably worse every time without?
This is a tough one. I do know that B vitamins should be taken together and a large dose of only one can cause a deficiency of the others > I always have people take a B50 complex, even if I can diagnose, lets say a B6 deficiency. B1 and niacin have everything to do with mental health. Take 2 B-50s a day. Remember that your urine will turn bright yellow-no cause for alarm.
