November 3 at the University of Toronto, Ontario, Canada, noted
doctors Cedric Garland and Tracey O'Connor are running a seminar
on how vitamin D can be used to prevent breast cancer as well
as infectious diseases, type 1 diabetes, hypertension, colon cancer,
and falls in the elderly.
will include some of the best-known vitamin D researchers/practitioners,
such as Robert P. Heaney, Reinhold Vieth, John White and Susan Whiting.
It is estimated
that 25 to 50 percent of any healthcare budget could be saved with
adequate vitamin D serum levels.
will look at the current research and practice with vitamin D to
enable everyone to take action today based on what's known to solve
the deficiency epidemic, and to start the prevention of many diseases.
As more and
more scientific evidence emerges, confirming that currently recommended
daily allowances (RDA) of vitamin D are grossly insufficient for
young and old alike, many have asked me to clarify the recommended
dosages, especially as it pertains to children.
Information about Adult Vitamin D Requirements
Before I begin,
I want to emphasize that under summer conditions it is frequently
possible to generate about 20,000 units of vitamin D by exposing
your skin to the sun. That fact makes these recommendations seem
more in line with reality.
the U.S. RDA for vitamin D is 400 IU (international units) for the
majority of the population. (IU is frequently shortened to just
units.) This dose was recommended to prevent rickets,
which works well, but does nothing to give the far more important
protection from cancer, heart disease and infections.
the healthy blood levels in the graph below, most adults will need
about FIVE THOUSAND units of vitamin D every day. Interestingly,
the majority of people I see in my travels that are taking vitamin
D are taking 1,000 units, and they believe they are taking high
doses. Dont fool yourself, as an adult, you likely need about
5,000 IUs a day.
worry that if they are in the sun that they will overdose on vitamin
understand that about 10 percent or more of the people reading this
need significantly more than 5,000 units. I have seen people requiring
over 30,000 units of vitamin D a day to reach therapeutic levels
of 25 hydroxy D in their blood.
that the ONLY way to know for sure is to get your blood level tested,
which Ill go over in just a moment.
RDA Guidelines for Vitamin D are Outdated in Light of New Research
Based on the
most recent research, the current recommendation is 35 IUs
of vitamin D per pound of body weight.
So for a child
weighing 40 pounds, the recommended average dose would be 1,400
IUs daily, and for a 170-pound adult, the dose would be nearly
important to realize that vitamin D requirements are highly individual,
as your vitamin D status is dependent on numerous factors, such
as the color of your skin, your location, and how much sunshine
youre exposed to on a regular basis.
these recommendations may put you closer to the ballpark of what
most people likely need, it is simply impossible to make a blanket
recommendation that will cover everyones needs.
So how do
you ensure optimal vitamin D levels for yourself, your child, and
is the ONLY Reliable Way to Determine How Much Vitamin D You or
Your Child Needs
Yes, the only
way to determine the correct dose is to get
your blood tested since there are so many variables that influence
your vitamin D status.
using Lab Corp in the U.S. If you get it done by Quest, youll
need to divide your result by 1.3 to get the real number.
For your convenience,
by years end we hope to offer a blood test that those in the
U.S. can do locally and does not require a doctors order.
test your doctor needs to order is 25(OH)D, also called 25-hydroxyvitamin
D, which is the better marker of overall D status. This is the
marker that is most strongly associated with overall health.
Determine Your OPTIMAL Level of Vitamin D
its important to realize the difference between what conventional
medicine considers to be normal, versus what is optimal.
25-hydroxyvitamin D lab range is between 2056 ng/ml. As you can
see in the chart below, this conventional range is really a sign
of deficiency, and is too broad to be ideal.
In fact, your
vitamin D level should never be below 32 ng/ml, and any levels
below 20 ng/ml are considered serious deficiency states, increasing
your risk of as many as 16 different cancers and autoimmune
diseases like multiple sclerosis and rheumatoid arthritis, just
to name a few.
value that youre looking for is 5065 ng/ml.
applies for everyone; children, adolescents, adults and seniors.
are based on healthy people in tropical or subtropical parts
of the world, where they are receiving healthy sun exposures. It
seems more than reasonable to assume that these values are in fact
reflective of an optimal human requirement.
worthwhile to clarify here that ng/ml are U.S. units of measure.
Much of the world uses nmol/l. If your test results are measured
in nmol/l, simply multiply the above values by 2.5 to get the correct
your skin is, the farther away from the equator you are, and the
further away you are from the summer months, the less likely it
is that you will produce adequate vitamin D levels from sun exposure
In these cases,
supplementing with vitamin D is acceptable, but I strongly recommend
you monitoring your blood levels regularly when taking oral vitamin
D supplements to make sure youre staying within the optimal
with the Right Kind of Vitamin D
There is one
other thing you need to be aware of if you choose to use an oral
vitamin D supplement and that is that there are basically two types
one is natural and one is synthetic.
one is D3 (cholecalciferol), which is the same vitamin D your
body makes when exposed to sunshine
one is vitamin D2, which is sometimes called ergocalciferol
form of the vitamin is in your body, it must be converted to a more
active form. Vitamin D3 is converted 500 percent faster than vitamin
D2, and is clearly a better alternative.
aware that nearly all the prescription-based supplements contain
synthetic vitamin D2, so if you receive a prescription for vitamin
D from your doctor, youre most likely receiving the inferior
the Word Out about the Benefits of Optimizing Vitamin D Levels
When it comes
to the benefits of optimizing your vitamin D levels, the evidence
is simply overwhelming. Research shows you can drastically reduce
your risk of cancer and countless other chronic diseases by getting
safe sun exposure, using a safe tanning bed, or taking a high-quality
Yet, a great
deal of people around the world have heard nothing of this great
discovery. Its even likely that your doctor is
among them, which is why its so important to educate yourself.
As a result
of flawed assumptions about sun exposure, and the subsequent recommendations,
a vast majority of people are deficient in vitamin D. Its
thought that over 95 percent of U.S. senior citizens may be deficient,
along with 85 percent of the American public.
word needs to get out but the mainstream media is slow to react.
Plus, theres no money to be made on selling vitamin D (its
one of the most inexpensive supplements around) and sun exposure
is free! So dont count on any major corporations or drug companies
to help get the message out (rather, count on them to try and suppress
this lifesaving information).
this information goes largely unnoticed, the more people who will
die unnecessarily from potentially preventable cancers and other
GrassrootsHealth D*action is on a mission to get the word out and
solve the vitamin D deficiency epidemic in just one years
Project: How YOU Can Make a Difference
has launched a worldwide public health campaign to solve the vitamin
D deficiency epidemic in a year through a focus on testing and education
with all individuals spreading the word.
And you are
all invited to join in this campaign!
With Dr. Garland
at the helm, The D*Action Project will be monitoring, for five years,
the health outcomes of individuals who get their vitamin D levels
to the levels of 4060 ng/ml. I would highly recommend that
you optimize your levels to the high end of this spectrum, as optimal
vitamin D levels are 5065 ng/ml, or 6590 ng/ml if you
are treating cancer.
Baggerly, director of GrassrootsHealth:
will be tracking the incidence of many diseases, from cancer to
diabetes and muscular function as well as pain levels to see what
effect the higher vitamin D levels may have.
to see a significant reduction in the incidence of breast cancer
(and its recurrence), colon cancer, diabetes and myocardial infarction,
compared with the general population. With the expansion of the
project by individuals, we could substantially reduce this epidemic
in a few years!
a health questionnaire and test your vitamin D levels two times
per year during the 5-year program to help demonstrate the public
health impact of this nutrient.
is sponsoring the use of blood spot test kits (laboratory analysis
done by ZRT Labs) for a $40 fee to each individual. The tests are
to be done twice a year by each individual along with the submission
of some basic health data. The fee includes:
D blood spot test kit to be used at home (except in the state
of New York)
are sent directly to you
You will be
asked to take a quick health survey and also to take action to adjust
your vitamin D levels to get into the desired ranges, ideally in
consultation with a knowledgeable health care professional.
you provide in the health survey will then be used in a five-year
study to evaluate the results of the program in disease prevention,
and to help create a long-term plan for public health.
depends on a true “grassroots” health movement. Together we can
stop the vitamin D deficiency epidemic in its tracks and improve
the health of millions of people.
100 of you joining today, and getting two friends to join in two
weeks (and those two friends getting two more), by week 42 there
could be 400,000,000 people who are vitamin D “replete” (more than
the United States population)!
