Q & A
Why is vitamin D considered the number one deficiency in the world?
-Vitamin D is considered the number one deficiency due to its critical importance in various bodily functions and the fact that many people do not get enough of it, leading to a strong correlation between low vitamin D levels and overall health.
What is the classic role of vitamin D in the body?
-The classic role of vitamin D is primarily associated with calcium and phosphorus regulation and bone health, aiding in the proper hardening and formation of bones to prevent conditions like rickets.
How has the understanding of vitamin D's non-classic roles evolved?
-The non-classic roles of vitamin D, such as its involvement in immune function, apoptosis, cell proliferation, and neurogenesis, have been largely understood in the last 10 years, highlighting its broader importance beyond bone health.
What is the connection between vitamin D and chronic disease or frailty?
-Vitamin D is considered a biomarker of chronic disease and frailty because low levels of vitamin D are strongly correlated with poor health outcomes and an increased risk of various diseases.
How does vitamin D influence the immune system?
-Vitamin D activates and regulates immune cells, playing a crucial role in immune function. Low levels of vitamin D can lead to impaired immune responses and increased inflammation.
What is the recommended daily intake of vitamin D, and why might it vary?
-The basic recommendation is at least 600 IU's per day for most adults and 800 IU's for those over 60. However, individual needs may vary due to factors like sun exposure, genetics, and overall health.
How does air pollution affect vitamin D production in the skin?
-Air pollution can interfere with the skin's ability to produce vitamin D through UV radiation due to the presence of pollutants that block or reduce the effectiveness of UV rays.
What dietary sources are rich in vitamin D?
-Rich dietary sources of vitamin D include cod liver oil, cod liver pate, and irradiated mushrooms. Other animal products like butter, cream, and eggs contain smaller amounts.
Why is it important to consume vitamin D with fat in a meal?
-Vitamin D is a fat-soluble vitamin, so consuming it with fat helps in its absorption. Eating it with a meal, especially the largest meal of the day, can increase absorption by up to 50%.
What is the role of the vitamin D binding protein (VDBP) in the body?
-VDBP is responsible for transporting vitamin D to various parts of the body where it is needed. Low levels of VDBP can lead to reduced vitamin D activity and an increased risk of certain cancers.
What are some factors that can lead to vitamin D toxicity, and how can it be avoided?
-Factors leading to vitamin D toxicity include excessive supplementation without monitoring. To avoid it, individuals should measure their vitamin D levels through blood tests, supplement appropriately, and stay within the optimal range of 50 to 80 nanograms per deciliter.

Hello Health Champions. Today we're going to talk about the number one vitamin D danger you
must know. You can make a very strong case for vitamin D being the number one deficiency in
the world and not only that but it's of critical importance and we're only just learning just how
important it is in fact some people have said that it's a biomarker of chronic disease and
Frailty in other words looking at nothing else like you only get one thing on the blood work
and there's a very strong correlation between your vitamin D status and how well you're doing
overall so we're going to talk about a number of critical steps that we all have to have in place
in order for us to utilize vitamin D properly and if you want to follow along and get a copy
of these slides then there's a link down below so that you can get that now when we're talking about
What vitamin D does there there is a classic role and a non-classic role so typically vitamin D is
primarily associated with calcium phosphorus and Bone about depositing getting vitamin D
gets calcium into the bone so it can Harden and make proper bone and this was found out in 1920
based on something called rickets if you have a severe deficiency of vitamin D as you're growing
up as your bones are growing and lengthening you can't make hard bone and you get what's
called osteomalacia Soft bones and they found out that vitamin D was completely responsible
for these soft bones and as soon as they provided some vitamin D they solve the problem of rickets
but that was only one thing that was the first thing that found but it's only one thing of
What vitamin D does so now we have learned more about its non-classic role and this has to do
with immune function about activating immune cells regulating immune cells has to do with
apoptosis the lifespan and the programmed cell death of cells vitamin D is critically important
to regulate inflammation so if vitamin D is low inflammation goes up it is also involved with
neurogenesis that means building new brain tissue making new brain cells new brain connections as
in repairing brain tissue after concussions maybe but also in terms of learning new things you have
to make new connections and vitamin D is critical for that so here where there's some controversy
that most of these non-classic roles we have learned in the last 10 years not all of it but
the vast majority that we know about vitamin D we've learned in last 10 years to compare with
the calcium stuff we found out over a hundred years ago but some people are kind of stuck in
this old thinking so when we ask if you're getting enough vitamin D some people kind of argue that
yeah you have enough vitamin D to make bone and that may be true but the question then is do we
have enough vitamin D for all these other critical functions but important as this stuff is there's
way way more so cell proliferation for example the production and the maturation of cells the cell
differentiation the ability of a cell to become a bone cell or a heart cell or a liver cell or
a brain cell that's all about differentiation and about Gene stability the stability of your genetic
makeup of your DNA so when this is working we have healthy tissue now there's something called cancer
and cancer is characterized by uncontrolled cell proliferation it is with poor cell differentiation
and with genomic instability with those three things in place as we could have with low vitamin
D that is called cancer so especially malignant bad cancer that is uncontrolled is associated
with low vitamin D another thing that is becoming rampant is autoimmune disease the most common one
is for thyroid and we test thyroid antibodies on all of our blood work and we find it probably in
20 30% of people there are thyroid antibodies but not just thyroid there is rheumatoid arthritis
there is lupus there is ankylosing spondylitis there is psoriasis or psoriatic arthritis and
the list goes on and on and on even type one diabetes is an autoimmune disease that can be
influenced by vitamin D and then we have all of the neurodegenerative diseases the breakdown of
nervous system tissue or insufficiency such as in Parkinson's or Alzheimer's dementia we also have
neuro psychiatric disorders like schizophrenia and depression that are also influenced by
vitamin D so I think you can begin to see just how important it is that there's virtually no
body function where vitamin D is not involved so to call it important is an enormous understatement
and just like we said before you could look at Vitamin D as a single biomarker and get a pretty
good idea of how healthy this person is and then a good question is is the vitamin D a cause or
result of the disease in other words are people sick because they don't get enough vitamin D or
is the vitamin D low because they're sick and can't process it or utilize it properly and the
answer is definitely both that if you're low in Vitamin D it can call cause all sorts of problems
and if you are sick you're not going to process vitamin D as well so it kind of becomes a vicious
cycle there so just how big of a problem is this worldwide well officially you're called deficient
if you are below 20 nano-grams per deciliter on a blood test and that's about 42 to 97% of the
world's population depending on different regions depending on the country so in some countries
where they fortify and they supplement the food more they can be as low as 40 but there's still
40% of the population in those places that are less than 20 nano-grams which is disastrously
low and in some areas especially in the Middle East you can find as much as 97% of people being
deficient and then someone said well that can't be right that many people can't possibly be deficient
so they tried to kind of change the guidelines a little bit and they said well you know we found
that even at 12.5 nano-grams most people still mineralize bone pretty well but see now they're
back into that classic role where they're mostly concerned with whether you can put calcium in the
bone or not they're not really addressing the bigger picture either way even 20 nano-grams is
way way too low and then the next level up they're not calling you deficient just insufficient and
that is when you're below 30 nano-grams per deciliter but like I hinted a lot of these
numbers are mostly concerned with the classic role are we able to mineralize Bone so the question
is what's really optimal if we really want the full benefit for hundreds and hundreds of these
critical functions how high do we really need to be so we're going to talk you through a few steps
where you can start understanding that a little bit better so I'm going to tell you a little story
about the steps necessary for utilizing vitamin D so classically the idea is that we are out in the
sun and we get sunlight and as our skin is exposed to the UV radiation now we make vitamin D in the
skin and all should be well but most people would agree today that what we can produce via the skin
is just not enough today because there's so many different factors that can interfere and one for
example is air pollution that because of the extensive amount of air pollution we're not
making vitamin D the way we used to another thing is that if you rent around naked in the sun all
day long you'd probably be okay but I have noticed most people tend to wear clothes and they tend to
spend quite a bit of time indoors and and also pigmentation the darker your skin the more you
kind of repel that UV radiation so the darker your skin the less you can convert and make vitamin D
latitude if you live really far from or quite far from the equator you also don't get as much sun
or not the same intensity of sun uh the intensity will change with the season and the time of day
if you're most F out in the sun like toward the end of the day then the sun isn't strong enough
to really convert a lot either then as we age the conversion goes down further and then there's all
these different conditions like insulin resistance which 80% of the population has to some degree
where they eat too many carbohydrates and too much sugar and the insulin stops working properly it's
not enough so we have to make more insulin and we be become insulin resistant that also interferes
with vitamin D production so for most people the only realistic alternative is to get vitamin
D also through diet and or supplementation and whether we get it through diet or supplementation
now of course we have to absorb it and in terms of diet there's very very few dietary sources really
it's a few animal products the only Rich product really is is cod liver oil and cod liver pate if
you eat those on a regular basis and the other one would be irradiated mushrooms that's a pretty
strong source so mushrooms that have been exposed to UV light there's a little bit in various animal
products and animal fats like butter and cream and animal fats and eggs but not really enough
so supplementation is really the only practical and reasonable way for most people to get their
vitamin D on a daily basis so now when we eat it as food or a supplement of course it gets into
the stomach and we have to break it down and in order to break it down we need digestive enzymes
to break down our food and because vitamin D is a fat soluble vitamin we also need to eat it with
fat if you eat a very low fat diet and you don't release enough bile for example you're not going
to break down and make use of that vitamin D very well in fact they found that by eating a vitamin D
supplement with the biggest meal of the day you could increase absorption by 50% because it's
absorbed as part of food as part of fat and if you have a bigger meal then there's going to be more
digestive enzymes and a more involved absorption process for that but then the vitamin D has to be
transported so just because it got in your stomach and you managed to absorb it and even get it into
the bloodstream it still doesn't do you any good and there is something called a vitamin
D binding protein VDBP for short and if that protein is is low that means that there's less
vitamin D activity because virtually no vitamin D is floating around by itself it's all carried to
where it needs to go by this VDBP so not only do you need to have enough vitamin D you also
need to have enough of this protein and if you don't for example they have found an increased
risk of malignant tumors especially as it relates to breast cancer prostate cancer and colorectal
cancer and there is a strong association with these Cancers and a low VDBP and then of course
if you don't have enough of the protein it's still going to help to take more vitamin D so
that you can saturate it better so that there's more available and in fact I found that in a
group of people just taking 1,00 international units per day which still isn't a whole lot they
reduce the risk of this cancer by 60 to 77% but the binding protein also isn't enough it can only
transport it but now we need to get it into the cell so we have all these different steps
that build on each other and the next is like I mentioned to get it into the cell and now we
have something called a vitamin D receptor so The Binding protein is going to take this Vitamin D
from the bloodstream or from the skin and take it to its Target organ and now we have these little
receptors on the surface of the cell and only if those VDR receptors are working can we get
the vitamin D in and express that biological function and these vitamin D receptors are
basically on every cell in the body but they're more highly expressed where the vitamin D is the
most important and these would be places like your kidney cells your immune cells your bone cells but
also in special places in your nervous system a lot of different places but among others the
substantia nigra which is associated with making dopamine and Parkinson so if you have low vitamin
D you can't really get the full activity out of your substantia nigra your dopamine goes down
and you're at increased risk for Parkinson. Hypothalamus is an area that regulates your
hormones and your hunger and your thirst and temperature and so forth so now when these
areas don't work now we have neuro-psychiatric effects like schizophrenia depression we have
neuro-cognitive like Parkinson's and various motor disorders and dementia and we even have a
lot of different endocrine disorders and hormone imbalances even diabetes has a very strong link
to vitamin D and they link it specifically to this vitamin D receptor both type one and type
two diabetes so when vitamin D is low now there is less insulin release we produce less so we can't
manage blood glucose as well but the main thing of course leading to diabetes to type two is in
insulin resistance when we have a lot of vitamin D then insulin resistance goes down when vitamin
D is low insulin resistance goes up and when our immune system is down if vitamin D is low immune
regulation goes down now we have less defenses against type 1 diabetes which is an autoimmune
disease and that brings us to co-actors so we can go through all these different steps we can get
the vitamin D into the cell but we still can't necessarily have vitamin D activity at least
not all of it because most nutrients most enzymes and co-actors they work together with other things
and the number one co-actor to help you process vitamin D is going to be healthy foods rich whole
healthy foods that are grown the right way and cooked the right way provide more nutrients more
co-actors than anything else possibly could if you eat processed food and a bunch of sugar now you're
missing a little bit of everything the number two thing is exercise believe it or not because
exercise optimizes the function it activates every cell in your body it allows it to live up to its
potential if you will now first and third place is is adequate vitamin D intake so whether you get it
from the Sun or whether you need to supplement uh obviously you have to get enough vitamin D one way
or the other number four is magnesium magnesium participates in hundreds of different chemical
reactions and Pathways in the body and it is the most important co- factor for vitamin D to do its
thing number five is omega-3 fatty acids the EPA and the DHA they are also essential for activating
and transporting vitamin D number six is zinc if you haven't noticed yet zinc tends to show
up in all sorts of places number seven is boron which is another essential mineral and number
eight is vitamin K2 now some people need to add that as a supplement some people can manufacture
it through the gut and we do get some through food as well a lot of times it is recommended
that you get your vitamin D3 in combination with a vitamin K2 I haven't found that to be optimal
most of the time I find that a lot of people need to start with vitamin D3 and do that for maybe 3
to six months and then maybe for some of them to start adding adding in vitamin K2 but how much
vitamin D do you need to take we've pretty much concluded that most people should supplement but
how much so the basic recommendation is that you should get at least 600 IU's per day international
units and if you're over the age of 60 or so you should get 800 IU's now if you're in a different
part of the world sometimes they measure this in micro-grams and then you divide the international
units by 40 to come up with the micro-grams and some nutrition labels will have both the standard
guidelines also say that 2,000 IU's is the max that you should ever get now here's the problem
that for a lot of people that is not going to be enough that 2,000 IU's might be okay for
some people and it's a lot of genetic factors it's about sun exposure Etc but 2,000 IU's is
not going to be enough for most people 5,000 is going to be okay for a lot of people but we also
have a lot of people in the clinic taking 5,000 IU's and they're still deficient on their blood
work even after months of taking that and we test vitamin D on everyone in the clinic some people
take 10,000 and it is probably too much for most people so in the clinic we find that the majority
of people probably Center in around 5,000 IU's if they take 10,000 that if they're really deficient
we probably put them on 10,000 for a month or two but in the long run 10,000 is going to put
you over it's going to put you into Vitamin D toxicity which is also something that you
really don't want so here's the thing because there's so many variables so much individual
variability and so many factors to weigh in you really don't know unless you measure you got to
get a blood test and you got to get the level so next time you do blood work you have to either
order it or insist that they they put it on there and once you get your results back from the blood
levels what are we talking about about what should a good level be well less than 20 nano-grams is
like we said it's deficient it is much under it's in the Red Zone basically and if you're in the US
typically they're going to measure nano-grams per deciliter if you're in other parts of the
world they might measure in nano-moles per liter and the way to get from one to the other is you
multiply the nano-grams by 2.5 so I'll give you both units here then in the orange Zone meaning
you're insufficient it's still too low but it's not critical that's 30 nano-grams which would
be 75 nano-moles now what most people who are involved with functional medicine with nutrition
with holistic practices that people that do a lot of blood work and specialize in that they will set
the lower limit at 50 nano-grams which would be 125 nano-moles and the upper end of optimal is
probably around 80 nano-grams or 200 nano-moles so that's the range that you're looking for optimal
is between 50 and 80 and the reason that we want to be in this range and for a lot of people you
probably want to be toward the higher end of that is that while some people can probably get by
with 30 like we just talked about there's so much individual Variability in terms of absorption in
terms of binding protein transport and vitamin D receptor and your availability of co-actors that
if you have one or more limitations along the way then you have to compensate by having some more so
if you are hovering around the upper end you're probably doing well but we also get people in on
the blood work and now they're over a hundred and this is where we want to back off because there
is such a thing as Vitamin D toxicity it can put your blood calcium is too high it can cause all
sorts of problems in your body so you really don't want to go too high either and that's why it's so
important to measure this stuff so 100 nano-grams would be 250 nano-moles and where it really gets
to be a problem is over 150 nano-grams or 375 nano-moles this is vitamin D toxicity and it's not
real easy to get there but you want to make sure you don't get even close you probably have to take
tens of thousands for quite a long time but like we said there's also some variability and we've
had people get to a hundred without taking a whole lot for some people that could be two three four
5,000 and other people need to take 10,000 and they still don't get there so you need to measure
it and you need to stay and monitor and then stay in a good range so I hope you see that vitamin D
is too important to ignore it's too important not to know where you are it governs so many critical
functions so you need to measure you need to know where you are you can't just take 2,000 or 5,000
and assume and then you supplement based on that measurement and then you recheck and you Monitor
and then you rinse and repeat as necessary after you have in the beginning you probably want to
check every two to three months until you get a handle on it and I think you should check blood
work anytime you try to make changes you should get blood work every three months once you get
some results and you learn your Baseline and you get stable you don't need to take blood
work nearly as often and the same holds true for vitamin D but you need to start understanding how
