Usefulness of Vitamin D supplements for bone health

Sweet spot doesn't mean higher numbers are bad. I interpret it as "30-50 is sufficient for most people." People with osteoporosis can use higher amounts to help the body absorb calcium, along with taking K2 to help the calcium get to the bones.
I believe vitamin D toxicity is associated with levels 150 and higher. Too much can cause hypercalcimia, which can result in plaque in the arteries.

rjd, njx58 has the answer. The National Institute of Clinical Health likes 30-50, but the Endocrine Society likes70 to 100. I have osteoporosis so I keep mine at 70. With endocrine disorders you'd want to maintain higher levels because it reduces the inflammation caused by autoimmune and such.
When I started Forteo, my levels dropped, so I increased intake.
Vitamin D has a half life of 12 to 13 days. An d can be stored at half levels for 2 to 3 months. If you are lucky enough to have extra fat, your body is able to store vitamin D longer.
I really like your question. We have to think our way through everything.
