How much vitamin D do I need?
In November 2010, the Institute of Medicine's expert committee set a new "dietary reference intake" for vitamin D.
Assuming that a person gets virtually no vitamin D from sunshine -- and that this person gets adequate amounts of calcium -- the IOM committee recommends getting the following amounts of vitamin D from diet or supplements (Note that the IOM's upper limit is not a recommended intake, but what the IOM considers the highest safe level):
Teriparatide (Forteo) is self-injected into the skin. Because long-term safety is not yet established, it is only FDA-approved for 24 months of use. It reduces spine fractures in women with known osteoporosis, but reduction of hip fracture risk is currently unproven.
Who Should Take Forteo?
Men who have osteoporosis and postmenopausal women can take Forteo.
Forteo is not used to prevent osteoporosis or to treat mild osteoporosis.
This drug should be used if you've had at least one bone fracture due to thinning bones, you are at high risk of fractures, or you haven't responded to other osteoporosis therapies.
