in the blood.
There are several ways to think
about this. One is regarding public
health for the entire population,
understanding that the more melanin
you have in your skin, the lower
your vitamin D levels will be. Some
people have so little melanin and are
very efficient at making vitamin D
that a short walk to the mailbox will
generate quite a bit.
But the more melanin you have in
your skin, the lower the level of 25-
hydroxy vitamin D you will have. So,
when you think about a public
health situation, you have to think
about all these people who have
very low levels such as African
Americans. That’s one of the reasons
that we recommend 5,000 interna-
tional units (IU)/day because 95% of
the people who take 5,000 IU of
vitamin D/day will get the full health
benefits of vitamin D and no one will
get toxic effects.
Intake of 5,000 IU of vitamin
D/day will generally lead to a 25-
hydroxy vitamin D level of about
50–70 ng/ml, although that amount
varies considerably from person to
person. There’s a large genetic facto
in the determination of your vitamin
D level, and this surprises a lot of
people. You inherit your vitamin D
machinery and this affects how high
or low your actual vitamin D level is
in the blood. If you think about it in
terms of public health involvement,
it’s a Gaussian distribution where
you want to shift the curve to the
right so that nobody’s levels are
down around 15 or 20 ng/ml; at the
same time, nobody has levels of 15
ng/ml.
Levels of 50 ng/ml are ideal for on
other reason. Think of vitamin D as
being like a lake on top of a moun-
tain. There are many streams that
flow down the mountain from the
lake. As you go down the mountain,
there are hundreds of pools that are
being fed by this lake at the top.
When the lake gets low, the pools
dry up. This is much like the way
vitamin D synthesis works. Vitamin
in the form of 25-hydroxy vitamin
is the lake on top of the mountain.
This lake is involved with calcium

hydroxy vitamin D (or 25-(OH)D).
After vitamin D is formed in the skin
or put in your mouth, it goes to the
liver where it is hydroxylated by two
enzymes to form 25-hydroxy vitamin
D, which can be measured in the
blood. This is used to determine vita-
min D adequacy.
For years and years, the range in all
major reference labs was about
20–100 ng/ml. It was found people
having levels of 10 ng/ml or less
often had rickets or osteomalacia,
the adult form of rickets. So, 20
ng/ml is high enough not to get rick-
ets, but 20 ng/ml is still on the low
end.
On the other hand, we have life-
guards in Miami Beach in August
who have levels near 100 ng/ml. This
is high on the normal range of
20–100 ng/ml. As more and more
research came out, the lower range
moved from 20 to 25 to 30 ng/ml.
Now, most labs list 30 ng/ml as the
lower limit of normal.
So, the question is not what is the
best vitamin D intake, but what is
the ideal 25-hydroxy vitamin D level
