Widespread vitamin D deficiency poses risk: study

Still think they have any idea what a "safe" supplement is and how to dose it?

"Many young children do not get enough vitamin D, an often invisible deficiency that can show up later as broken bones or a weakened immune system prone to disease, researchers said on Monday.

Two out of five U.S. children aged 8 months to 2 years who took part in a 380-patient study at Children's Hospital Boston had less-than-optimal blood levels of vitamin D."

BTW, the researchers found that human breast milk is no good for infants:

"Also at risk for a vitamin D deficiency were breast-fed infants, because 'breast milk is the perfect food except that it lacks vitamin D,' Gordon said."

Researchers know better than evolution or intelligent design, whichever you believe.
