New Research on Vitamin
D, Part 2: How Much
Vitamin D Do We Need for
Optimal Health? |
WholeFoods Magazine
by: Richard A. Passwater, Ph.D.
In the previous section, Dr. Passwater
chatted with John J. Cannell, M.D.,
about the function of vitamin D and the
recent developments that affect our need
to increase our dietary intake of vitamin
D. This month, they discuss optimizing
our vitamin D intake.
Passwater: Dr. Cannell, how do we
know how much vitamin D is
required for our optimal health?
Cannell: We have learned a lot
about this question by studying the
amount of a compound called 25-

polymorphisms in the vitamin D
receptor simply mean more vitamin
D is needed by some SNP to activate
sufficient numbers of these receptors
on the genes. All of the vitamin D
receptor polymorphisms are func-
tional; it is not as though some work
and some don’t. However, variation
in the functionality of these polymor-
phisms is one of the reasons why we
recommend a 25-hydroxy-vitamin D
level of 50 ng/ml in the blood rather
than the IOM’s recommendation of
20 ng/ml. We want to be sure every-
one gets a benefit.
Passwater: Let’s look at how you
and most scientists arrive at your rec-
ommendation and how the IOM
arrived at theirs in June’s column.

more than 40 books and 500 articles on

gle nuclear polymorphisms (SNP)?
Are they an important factor?
Cannell: There are indeed SNPs.
When mutations become so com-
mon that 10–20% of us have them,
they’re no longer called mutations,
but are called polymorphisms. There
are many shapes of the vitamin D
receptor. It appears that some of the
vitamin D receptors are more func-
tional than others, although this has
never has been properly researched
and it’s not clear what this means at
this time. There is very little consis-
tent SNP research on vitamin D
receptor polymorphisms and the
results are not clear at this time.
In all likelihood, variations in any
