I'm 40 years old what vitamins is good for the bone.?

Vitamin D and K and. Vitamin d is the best-known vitamin for bone health, as it is essential for calcium absorption. Most adults need 2000-5000 units a day from oct.-april, or year round if you don't spend time in the sun. Less well known but also crucial is vit. K, which makes sure calcium goes into your bones-at least 1 mg/day, up to 45 mg for osteoporosis. And minerals like calcium, magnesium, boron & strontium help.
