It depends...: There are many good brands but i prefer high potency with minimal additives such as pure encapsulations, thorne and new chapter, available online & in some stores. I advise everyone take vit. C 1-2000 mg 2x/day & a quality mulitivit. That includes the 5-mtfh form of Folic Acid & 5000 units of vit. D in winter months .To prevent osteoporosis at least 1 mg of vit, k & perhaps a quality calcium/mag.
