I've been reading a COPD blog that Caroloctober kindly linked to in a recent reply and the blogger mentioned that taking 5000 IU of Vitamin D daily has helped in that it builds up the immune system, meaning less general illness and seems to keep most colds away, also any cold clearing quickly and most likely without giving an exacerbation.
I'm just wondering if anyone else has tried Vit D and found it helps in any way at all? And is it Vit D3?
I take Osteocare which has D3 in it at the rate of 10 mcg per dose of two tablets daily. Not sure how that compares with 5000 IU.
