The dairy cow knows the value of Vitamin D.
And now so do researchers.
Study participants were given Vitamin D supplements (typical infant multivitamins) from birth on and after a tracking period of 15 to 30 years it was found that they were 29% less likely to develop type 1 diabetes than those infants who did not receive the supplemental Vitamin D.

How Much Vitamin D Do We Need?
Per the Mayo Clinic:
“You’re unlikely to get too much vitamin D from the food you eat, and prolonged sun exposure doesn’t seem to cause vitamin D toxicity. Over time, however, megadoses of vitamin D supplements can cause
nausea, vomiting, poor appetite, constipation, weakness and weight loss. More seriously, excessive doses of vitamin D can raise the level of calcium in your blood — which can cause confusion and changes in heart rhythm. Generally, the upper limit for vitamin D is 2,000 IU a day.”
