My dietician recommended Flinestones Complete, 1 at a time, 2 times daily. Those are supposed to be taken separately from my Calcium (2 times a day, with meals) and My D3 is 2 pills a day and they never said to split them up so I do them at one time. I give myself B12 shots once a month.
Well, that's what I've done so far and what they've recommended.
