having chronic substrate deficiency. If
it is 30 ng/ml, you have a 75%
chance of having chronic substrate
deficiency. The results of Dr.
Heaney’s study are graphed in Figure
1.
Passwater: Dr. Cannell, you and
many, if not most, vitamin D
researchers are convinced by the
body of scientific evidence that
5,000 IU of vitamin D should be the
recommended intake for optimal
health. Previously, people had been
led to believe that only 400 IU was
adequate. Now, when people read
recommendations for 5,000 IU, they
worry that this larger amount may be
harmful. Perhaps, 5,000 IU seems to
be a large number to them.
Cannell: It is larger than 400, but in
the case of vitamin D, 5,000 IU is
only an eighth of a milligram of
cholecalciferol; that’s only 125
micrograms. Micrograms, not mil-
ligrams! There are 1,000 micrograms
in a milligram. Perhaps if the dosage
was stated in micrograms, they
wouldn’t worry.
Passwater: Last month, we dis-
cussed that in 1972, the U.S. Food
and Drug Administration (FDA) was
trying to lower the amount of vita-
min D available in supplements to
400 IU because of the FDA’s “con-
cerns” that more would be toxic.
How do you respond to those who
remark that at 5,000 IU, vitamin D i
toxic?
Cannell: They might think it’s toxi
but they can’t find a case in the
medical literature in the history of
the world that shows it is. They can’
even find a case of where somebod
taking 10,000 IU of vitamin D a
day—for no matter how many
years—caused vitamin D toxicity.
Passwater: That was true in 1972
when the FDA tried to ban any sup-
plement having more than 400 IU
(making them available by prescrip-
tion only) and in 1986 when I
reviewed vitamin D safety in this col
umn (1).
Where does vitamin D intoxicatio
begin?
Cannell: Vitamin D toxicity would
generally start to appear if someone
was taking 50,000 IU a day for man
