Vitamin D & Children’s Allergies

A few words from Dr. Chaney tell us that Vitamin D is important for children as well as adults:

“With the beautiful Spring flowers comes a whole new
allergy season.
And, of course, not all allergies are seasonal.
Allergies to foods, animal dander, mold and dust mites
occur all year around.
If your children suffer from allergies, here is
something that you should know:

Dr. Michal Melamed and colleagues have just reported a
major clinical study (Journal of Allergy and Clinical
Immunology, published online February 16, 2011) showing
that children and adolescents with low blood levels of
vitamin D are much more likely to suffer from allergies
than those with adequate blood levels of vitamin D.

They looked at vitamin D status (as measured by 25-
hydroxy vitamin D levels in the blood) and sensitivity
to 17 different common allergens in 3136 children and
adolescents aged 1 to 21 in the NHANES (National Health
and Nutrition Examination Survey) database from 2005
and 2006.

The data were adjusted for age, gender, ethnicity,
obesity, socioeconomic status and hours spent watching
television, playing video games or on the computer (a
measure of activity level – or more strictly speaking
inactivity level).

They found that children and adolescents with low blood
levels of vitamin (< 15 ng/ml of 25-hydroxy vitamin D)
were significantly more likely to suffer from 11 of the
17 allergies tested than those with adequate blood
vitamin D levels (> 30 ng/ml of 25-hydroxy vitamin D).

For example, they were significantly more likely to
suffer from allergies to peanuts, ragweed, oak, dog
dander and dust.

This is an important finding because previous studies
by Dr. Melamed and others have shown that up to 70% of
children in this country have low blood levels of
vitamin D and that the incidence of vitamin D
deficiency has increased significantly in recent years
– perhaps linked to all the video games & computer use
of today’s children.

Dr. Melamed suggested that it is perhaps no coincidence
that many children suffer from allergies and that the
incidence of allergies in children is also increasing.

Around 16 million children (16% of the population)
suffer from allergies, and the incidence of children
suffering with allergies has increased by 18% in just
the last 10 years.

So, if your children suffer from allergies, one thing
that you could do for them is to make sure that they
are getting sufficient levels of vitamin D in their

Dr. Melamed states: “The latest dietary recommendations
calling for children to take in 600 IU of vitamin D
daily should keep them from becoming D deficient.”
Of course, vitamin D is not a magic bullet. It is just
one of many things that you can do to reduce the risk
of allergies in your children.

A holistic approach to allergy reduction would include
a good diet that provides all of the essential
nutrients and a supplemental source of friendly
bacteria to support a healthy intestine and immune
It would also include non-toxic cleaning products to
reduce environmental allergen exposure.”

Dr. Chaney has taught biochemistry to medical and dental students for more than 30 years and has won several awards for teaching excellence.

He runs an active cancer research program and has published over 100 scientific articles and reviews in peer-reviewed scientific journals. He has also written two chapters on nutrition for a popular medical biochemistry textbook.

Shaklee’s Incredivites provide your children with
the recommended 600 IU of vitamin D along with all of
the other essential nutrients they need.
