Vitamin D is discussed frequently, and for good reason. ☀️
If you’re supplementing, vitamin D3 is typically recommended. When we check blood levels, the sweet spot is usually between 30 and 50 in the units your lab uses. For most people, around 2,000 IU per day is enough to get there.
Vitamin D is essential because it helps your body use calcium properly to support bone health. Calcium and vitamin D alone don’t build bone, and they’re not treatments for osteoporosis, but without enough of them, even osteoporosis medications don’t work as well.
I once heard a lecture showing that nearly half of women on osteoporosis medications had insufficient vitamin D levels—not a deficiency, but still insufficient. That matters.
Vitamin D deficiency causes rickets in children and osteomalacia in adults, but insufficiency is different and much more common.
That’s why I generally recommend that all women be on vitamin D supplementation as part of their overall bone health plan.
As always, talk with your doctor about what’s right for you.
