Vitamin D Needs
The recommended Daily Value (DV) for vitamin D is 800 international units (IU), or 20 mcg per day for all adults and children over 4 years old. For children aged 1–3, it’s 600 IU or 15 mcg per day (1). Other factors, such as having obesity or underweight, being physically inactive, and having certain genetic mutations, can also put you at risk of having lower vitamin D levels
And vitamins (A, C and K) are also involved. Vitamin D and certain minerals, in fact, play an important role in calcium homeostasis and calcium absorption.
