Vitamin D Supplementation Reduces
Asthma Attacks in Adults and Children
In the first study, asthma flare-ups were
reduced by 37%. In the second study,
flare-ups were reduced by 72%. That's
pretty impressive. And, equally
impressive, this reduction is achieved
merely by supplementing with a vitamin
that is good for you in so many other
ways as well. Sounds like a win-win
situation to me.

What is Asthma?
In asthma, the smooth muscle walls that
surround air passageways to the lungs swell,
tighten, and inflame, restricting the flow of
air. There are many things that can trigger an
asthma attack, including pollen, pets, mold,
respiratory infection, smoke, exercise, and
inhaling cold air.
Two recent studies show that vitamin D can
prevent or ameliorate asthma attacks.
Vitamin D supplements lead to fewer emer-
gency room visits.
Low levels of vitamin D may increase
chances for asthma attacks, but this is the first
review of results from placebo-controlled
asthma studies using vitamin D supplements.
Doctors analyzed findings from seven studies
covering 435 children, and two studies cov-
ering 658 adults, most with mild or moderate
asthma, and fewer with severe asthma.
Participants were ethnically diverse, coming
from North America, Europe, and Asia, and
studies lasted anywhere from four to 12
months.
Overall compared to placebo, those taking
vitamin D saw the rate of asthma flare-ups
requiring corticosteroid treatments decrease
by 37 percent. Chances of being hospitalized
or requiring an emergency room visit for
severe asthmatic episodes declined by 61
percent, with the number of hospitalizations
declining from 6 per 100 participants to 3
per 100 participants.

Fewer asthma flare-ups in kids
with the Common Cold
This was a study of vitamin D and acute
respiratory infections--specifically, the com-
mon cold in children younger than 18.
Doctors reviewed seven controlled vitamin
D supplement trials covering both healthy
kids and those with recurring acute respirato-
ry infections. While vitamin D did not reduce
the chances of respiratory infection, kids with
asthma and colds who took vitamin D saw
72 percent fewer asthma flare-ups during the
cold compared to kids with asthma who did
not take vitamin D.
