Apparently, children reared in cold and humid climates have a higher incidence of asthma than those raised in sunnier climates. In addition, children drinking mil also show higher incidents of allergies. Sun provides vitamin D. headed by epidemiologist Alberto Arnedo-Pena, published these findings in the 2010 International Journal of Bio-meteorology. American Journal of Respiratory and Critical Care found that asthmatics with low vitamin D levels had more severe attacks than those with normal levels.
How much Vitamin D to Take?
So how much should you take? Base it on blood levels. Take vitamin D until your blood levels fall between 30 and 74 ng/ml, or you feel remarkably better. Shoot for 50-70. If you supplement with D, measure your blood levels at least twice yearly to make sure you’re not getting too much. In 1999, Dr. Reinhold Vieth determined it’s practically impossible to become toxic on 2,000 IUs a day. You’ll find D supplements at the pharmacy and health food store with dosages of 5,000 or 10,000 IU per capsule preferably D3.
Over the Counter Supplements:
Over-the-counter vitamin D3 (aka cholecalciferol) is different from the drug that is vitamin D2 (aka ergocalciferol). D2 is synthetic and less potent than natural D3 supplements. Cod liver oil provides natural D3 plus healthy essential fatty acids. But the best and cheapest way to get vitamin D3 is from sunshine.
