As per the title, I am not sure I want my COPD exacerbations improved. They are annoying enough already. I would much rather they be reduced or weakened.

hat Vitamin D supplements can protect against chronic obstructive pulmonary disease exacerbations. The study was published in the journal The Lancet Respiratory Medicine.

THE CAPTION WAS MISLEADING.....

An ounce of prevention is worth a pound of cure.

Doesn't improved mean reduced/weakened/less violent. I'll take any of those.

LOL @ gnott
gosh, it has been known for years that most people are low vitD & that it automatically be screened any time CBC is done.
most people get a yearly physical & that includes a cbc (mine does anyway), that checks your vit D and also calcium levels~~~calcium & vit d go together.
also it needs to be vitD3 or it isn't absorbed & is a waste of your money.

mayo clinic has a list here of how much supplement to use for just about any condition;

i found it interesting that vit d can affect blood sugar levels so needs to be used with caution with diabetes---hmmmm

Yeah, comorbidities are a real annoyance. Most of us (especially if more seasoned) do suffer from more than one disease. So for anyone that is following this thread and is newly DX with COPD always reading the fine print when it comes to any kind of herbal / vitamin / mineral supplement is darn good advice. What was essentially benign in the old days can cause all kinds of subtle problems under the right (or wrong) conditions.

Big Pharma rules the "medical community" in their quest for billions every year in obscene profits. They spend hundreds of millions of dollars every year lobbying Congress and paying off both parties to prevent preventitive medicine and ignore consumer safety concerns.
