Why does my daughter get achy bones, fever and flu like symptoms more often then the average 12yr old...she has had bloodwork shes low on vitamin d.?

Needs D3: Vitamin d deficiency is widespread. The one to spot in the blood is 5-hydroxy (d3). We now know that this vitamin enters intgo the physiology of every cell in the body. At the age of 12 she is a physiological adult. Ask your pediatrician for the dose. The blood level should reach 60 to 80 units.

Let me help: Low vit d dose not cause all this problems you describe but low vit d should be corrected, ask her doctor what could be the cause because he know her more than any body else. Good luck thanks.
