Very interesting article.For many of us with osteoporosis caused by the dreaded steroids we are precribed VitD3 .Who would have thought it could be protecting our lungs also ? An additional dose in an inhaler or added perhaps to the ones we use already sounds like a good idea.I hope further research is done on this re dosage and most effective way to be administered as anything that can offset the severe effects that colds etc have on us 'lungies' could literally be a lifesaver.Thank you for posting this. xx

Very interesting. My husband and I take Vitamin D but I’m not sure what dose is best for him. I am also concerned that it might be a factor in causing his kidney stones .

Taking vitamin K2 [Mk-7] along with D3 should ensure that the D3 is activated for take up to the bones and not the organs.

If you are 50 and over, you need more vitamin D3. Part of the reason for this is that your parathyroid glands are usually less efficient at converting the storage form of vitamin D, D3, into the active form of vitamin D, D2.

Keeping enough vitamin D2 in your bloodstream requires having more D3 stored in skin and fat. Taking a supplement of up to 1,000 IU of vitamin D a day acts as "insurance" that your tissues will always have the activated vitamin D they need.

How much vitamin D3 should I take if I am deficient? Children and adults at any age can become deficient in vitamin D3, even if they get lots of sun. One study found that 1 in 3 professional surfers on the north shore of Maui, where the sun shines nearly every day, had a vitamin D3 deficiency.

Since toxicity symptoms are unknown below daily dosages of 40,000 IU per day, the US Institute of Medicine recommends taking up to 4,000 IU per day as an unquestionably safe dosage. The idea behind setting the limit low is making sure that even if a vitamin manufacturer accidentally made the product 10 times too strong or even if the consumer accidentally took more than one dose per day, there still would be no injurious side effects. Actually, you can take 5,000 to 10,000 IU per day will no ill effects.

Thanks for this. 5 years ago, following yet another exacerbation which landed me in hospital, my GP told me daily D3 would be likely to help me avoid exacerbations. I was cynical. I had not had my levels tested so don't know whether I was deficient or not. But I do know that during the last 5 years my exacerbations have reduced a lot. I shall continue taking D3!

Interesting 2greys My ulcers in my colon have cleared up and left; my respiratory illnesses have certainly lessened and my joint inflammation has lessened too since taking the vitamin d3 I don't take K2 - wondering whether I should x
