then i have a long ways to go just to get to 50i am starting on an over the counter vitamin d next week after i finish my perscription and i have seen where you have said d3 is better for bringing the levels in your blood so that is what i goti read the label and made sure. Your advice has been most helpful however i will not take b 12 again because as soon as i started taking it my RLS went out of control. it is way better since i went off it not completely but almost.Again thank you for you wonder helpful advice
