I have had pneumonia seven times in my past. Colds were a constant problem, but no more.

For the last five years I have taken vitamin D3 daily. I take 4000 IU.

I suggest you try it, for it may make a difference in your health.

Go ahead and take it but recently studies have failed to show any benefit of supplemental D3.

An exception might be if blood levels are low, but you have to spring for a lab test to find that out.

My 97 YO mother just had her serum D tested -- was in normal range.

Although the researchers identified 137 different health outcomes associated with vitamin D levels, they found that only 10 of these outcomes had been comprehensively tested in trials, and only one outcome - that an infant's birth weight is linked to a mother's vitamin D levels in late pregnancy - had enough evidence to deem it a "benefit."
