O witaminie D

Best ways to obtain Vitamin D

SUN - When one is exposed to the midday sun, the average person can produce
anywhere from 10,000 IU to 50,000 IU of vitamin D in the course of a
relatively short amount of time. As I stated above, it would take
significantly longer for persons with darker complexions to produce those
levels. If the skin overproduces vitamin D, the body will degrade the excess
on the spot. Therefore, one can never have high or toxic blood levels caused
by sun exposure alone. And remember, ALL of our ancestors got most of their
vitamin D from the sun. By the way, sun exposure increases the production of
endorphins which make us feel better and strengthen our immune systems.

So how do you accomplish "prudent sun exposure"? (Caution: This doesn't
apply to you if you are taking doxycycline! Avoid sun exposure until off the
medicine. Also if your skin is "Type I" or you have been told by your doctor
"no sun", then skip this next section. In either case, be sure to get a
vitamin D 25-OH blood test to see if you need to use diet and/or
supplementation to obtain your vitamin D.)

What I tell my patients to do is to plan on 10-30 minutes of sun exposure
(preferably in a bathing suit for larger skin exposure) 3-4 times a week
during summer months. The key thing to remember is that you should plan to
stop the exposure when you begin to notice a slight "pinkening" of the skin.
At the time you notice the pink, you can then apply sunscreen if you wish to
continue in the sun, or simply come out of the sun.

DIET - Although not the ideal way to get all of your vitamin D, certainly the
right foods could be helpful. In fact, in the Scandinavian countries,
apparently most people get their summer vitamin D from the sun and their
winter vitamin D from wild caught oily fish. Therefore, fish such as salmon
and mackerel would be very good sources of vitamin D and other excellent
nutrients such as omega 3 oils.

Another potential source is cod liver oil. A teaspoon of cod liver oil
contains about 400 IU of vitamin D, and it is believed that this fact resulted
in the government's establishment of 400 IU as the recommended amount of daily
intake of vitamin D. However, we now believe that 400 IU is woefully too low
a recommendation for vitamin D. One caution concerning the extensive use of
cod liver oil is the fact that it contains significant amounts of vitamin A.
High doses of vitamin A may have an adverse effect on the bones of some
people. Therefore, I recommend using some cod liver oil, but not making it a
major source of vitamin D for most people.

Perhaps the poorest dietary source is milk and for several reasons. First of
all, the amount of vitamin D in milk is inconsistent and is often not natural
vitamin D3, rather most often synthetic, non-human vitamin D2 is used.
Secondly, there is not enough in the average glass of milk to do the job, yet
people are lulled into a sense of complacency thinking that that is all they
need. Third of all, the majority of the world is lactose intolerant and
therefore avoids milk. So if you plan to get some of your vitamin D from
milk, don't count on too much from that source. Like cod liver oil, get some
vitamin D from milk if you can, but most dietary vitamin D should come from
fish sources.

Vitamin D Supplementation

The preferred form of vitamin D is human vitamin D, which is also known as
vitamin D3 (cholecalciferol). This is the form of vitamin D formed in the
skin when exposed to UVB radiation. A synthetic form is also available called
vitamin D2 (ergocalciferol). I don't recommend vitamin D2 unless there is no
choice except D2 because D2 is only 25-30% as effective as vitamin D3.

Before embarking on a vitamin D supplementation program, the first rule is
that you need to know your vitamin D 25-OH level. As I have stated before,
most experts do not recommend the 1,25-OH as a marker for vitamin D status.
Dr. John Cannell, Executive Director of the Vitamin D Council, states:
"Calcitriol [Vitamin D 1,25-OH] levels should never be used to determine if
you are deficient in vitamin D."

If your level is mildly low - 30 to 40 ng/ml - consider supplementation with
vitamin D3 at an amount of 1,000 to 2,000 IU per day.

When levels are moderately low - 20 to 30 ng/ml - consider using vitamin D3
2,000 to 3,000 IU per day.

If levels are very low - 15 to 20 ng/ml - consider using 3,000 to 4,000 IU per
day of vitamin D3.

Extremely low levels are less than 15 ng/ml, and this situation I suggest
supplementation with prescription 50,000 IU of vitamin D3 weekly for 4-8
weeks, followed by 4-5,000 IU of vitamin D3 daily. By the way, most
prescriptions of 50,000 IU of vitamin D are in the form of vitamin D2. You
may need to seek out and use a compounding pharmacy in order to get
prescription 50,000 IU vitamin D3. It is available but you may have to look
for it.

In extremely low levels, I routinely follow blood levels every 2-3 months
until levels are stable. All others, I check levels 2-4 times per year.
Adjustment in dosages should be made based on blood levels.

      Dzieki Artur za ten ciekawy artykul. Moj poziom witaminy D jest
      bardzo bardzo niski (7 ng/ml) wiec musze suplementowac. W tej chwili
      kapiele sloneczne odpadaja ( Paryz nie widzial slonca od kilku
      tygodni), zostaje wiec olej i suplementacja.
      A trzeba uwazac, bo mozna przeholowac.

            Ekspozycja na slonce, nawet na wzglednie krotko powoduje powstanie 10000 do
            50000 jednostek witaminy D. Osoby z ciemniejsza skora maja gorzej bo u nich
            produkcja witaminy D jest wolniejsza.
            Sloncem witaminy D nie da sie przedawkowac, bo wszelki nadmiar od razu w skorze
            jest niszczony.
            Przodkowie czlowieka uzyskiwali witamine D glownie ze slonca. Takze slonce
            powoduje powstanie endorfin, ktore polepszaja nasze samopoczucie oraz wzmacniaja
            system immunologiczny.
            Ekspozycja nie wchodzi w gre, jezeli ktos bierze leki uczulajace na slonce takie
            jak np doksycykline (lub inne tetracykliny lub levaquin). Sprawdz swoj poziom
            witaminy D 25 OH aby sie upewnic czy nie potrzebujesz suplementow tej witaminy.
            Pacjentom radze planowac 10-30 min slonca dziennie, najlepiej w kostiumie aby
            zwiekszyc ekspozycje skory 3-4 razy w tygodniu latem. Jezeli skora zaczyna by
            rozowawa nalezy zakonczyc ekspozycje lub nalozy krem ochronny.
            Dieta nie jest idealnym sposobem na zdobywanie witaminy D. W krajach
            skandynawskich ludzi e biora witamine D latem ze slonca a zima ze zlapanych
            dzikich ryb (przy okazji dostarczaja mega 3)
            Tran – lyzeczka zawiera zwykle 400 jednostek witaminy D i zapewne stad pochodzi
            poglad, ze tyle wlasnie czlowiek potrzebuje. Obecnie podejrzewa sie jednak, ze
            czlowiek potrzebuje tej witaminy znacznie wiecej. Problem z tranem jest taki, ze
            zawiera on tez ogromne ilosci witaminy A, ktora w nadmiarze jest szkodliwa a
            nawet trujaca. Dlatego tran tak i owszem, ale nie za duzo.
            Mleko i produkty mleczne to bardzo marne zrodlo witaminy D. Czesto jest to
            dodana sztucznie witamina D2 (mniej zalecana). Ryba (z tych tlustych) jest
            najbardziej zalecana. D2 syntetyczna jest marnym wyborem majacym 20-30%
            efektywnosci D3.
            D3 (cholecalciferol) tworzy sie wlasnie przy ekspozycji na slonce.
            Przed suplementacjami nalezy sie upewnic jaki jest poziom D 25 0H. Poziom
            1,25-OH jest mylacy.
            Jezeli masz - 30 to 40 ng/ml rozwaz suplementacje
            vitamina D3 1,000 to 2,000 jednostek dziennie.
            Przy poziomie - 20 to 30 ng/ml -
            2,000 to 3,000 jednostek dziennie.

            A jezeli bedzie tak nisko jak - 15 to 20 ng/ml – to 3,000 to 4,000 jednostek
            dziennie vitaminy D3.
            Jezeli test wykaze jeszcze nizsze wartosci to wtedy nalezy uzywac suplementacji
            50000 j tygodniowo przez 4-8 tygodni a potem 4-5000 j dziennie D3.
            Witamina D3 nie zawsze jest osiagalna (wszedzie jest D2) i czasami musi byc
            zrobiona w aptece na recepte.
            Poziom D we krwi trzeba sprawdzac 2-4 razy w roku i dopasowywac suplementacje do
            wynikow.

              A jak sprawidzic poziom witaminy D? Czy to badanie z krwi? Czy jest
              ono ogólnodostępne?

              Czy lekarz rodzinny może zlecić mi badania na poziom wit. D oraz
              żelaza?

          Witamina D poprawia funkcjonowanie ukladu odpornosciowego. W szczegolnosci
          powstaja bakteriobojcze polipeptydy, ktore moga nawet wywlolac reakcje Herxeimera.

          Reakcja Herxeimera niejednego lekarza juz zmylila odczytujac ja jako reakcja
          niekorzystna. Takze Marshall dal sie na to nabrac, kiedy zauwazyl, ze ekspozycja
          na slonce mu nasila objawy i stworzyl system leczenia w ktorym witamina D jest
          zabanowana. Pomimo, ze nie az tak duzo ludzi wskoczylo w tzw Marshall protokol
          to wiekszosc chorych z borelioza na wszelki wypadek unikala witaminy D. Do czasu
          az pewna odwazna pacjentka z Kanady zdecydowala sie isc pod prad i przywrocic
          swoj poziom witaminy D we krwi do normy, co spowodowalo u niej powrot do
          zdrowia. Od tego czasu MP zostal w zasadzie odrzucony a witamina D weszla do
          arsenalu srodkow uzywanych w chorobach odkleszczowych.
          Boreliozy widzi sie malo w miejscach bardzo naslonecznionych (tropiki) i byc
          moze wynika to z funkcji ochronnej witaminy D.

      The Vitamin Di Newsletter

      January 20, 2009

      The Institute of Medicine (IOM) has quietly announced composition of
      the next vitamin D Food and Nutrition Board (FNB), a committee that
      will set recommendations for both adequate intake and upper limits
      well into the next decade. The IOM allows public comments for the
      next nine days; see the bottom of the hyperlink below. Please take
      time to comment.

      www8.nationalacademies.org/cp/committeeview.aspx?key=49031
      Unfortunately, the scientists who have led the vitamin D revolution
      for the last ten years are all excluded. The debarred include, but
      are not limited to, Drs. Vieth, Giovannucci, Garland, Hollis,
      Heaney, Wagner, Norman, Hankinson, Whitting, Hanley, etc.. For
      example, Dr Hollis actually wrote and received an FDA
      Investigational New Drug ( IND) for vitamin D in 2003 that has
      allowed both himself and many other investigators to perform vitamin
      D studies with doses well above the current upper limits. Why is he
      not on the committee? Dr. Vieth has performed many of the recent
      upper limit pharmacological dosing studies in humans. Why did the
      IOM exclude Dr. Vieth?
      Has the chair of the new committee, Dr. Catherine Ross, ever
      published a paper on vitamin D? There is a difference between
      vitamin D and A. As editor of the Journal of Nutrition, I can only
      hope she understands the vitamin D revolution. Professor Patsy
      Brannon has researched nutritional genesi affecting the placenta and
      fetus. Let's hope she understands vitamin D's role in brain
      development. The brains of hundreds of thousands, perhaps millions,
      of fetuses - developing as you read this - are suffering the
      devastational damages of gestational vitamin D deficiency.

      Where are the investigators who have done the mass of the current
      work on vitamin D? Certainly, Drs. Aloia and Gallagher are
      excellent choices but what about the other members; do they
      understand the paradigm shift? In 2003, was Dr. Abrams a force
      behind the American Academy of Pediatrics idiotic reduction of the
      infant vitamin D requirement from 400 IU to 200 IU? Was he against
      the recent increase back to 400 IU last year? If so, history may
      record Dr. Abrams as one of the physicians responsible for the
      current childhood epidemics of autism, asthmai, and autoimmune
      diseasesi.

      Do Dr. Kovacs or Dr. Gallo have any experience in assessing dietary
      levels of vitamin D? How are these scientists going to represent
      obstetrics and pediatrics in a manner that protects pregnant women
      and children from the dangers of vitamin D deficiency? Dr. Jones is
      a excellent biochemist but again, has he published original data on
      vitamin D? Has Dr. Rosen? I hope Dr. Manson knows more about
      vitamin D than her studies with the Women's Health Initiative,
      incredibly expensive studies that simply showed meaningless doses of
      vitamin D are meaningless.

      Many of the excluded experts recently criticized the IOM using the
      strongest language to date:

      "Astonishingly, the FNB says that the adequate intake for vitamin D
      is the same for the largest pregnant woman as for the smallest
      premature infant (200 IU/d) — frightening advice for pregnant women,
      in light of animal studies that showed that gestational vitamin D
      deficiency causes both neuronal injury and autistic-like gross
      morphologicali changes in the brains of offspring. Furthermore,
      the FNB’s upper limits for a 1-year-old, 9-kg (20 lb) child and a 30-
      year-old, 135-kg (300 lb) adult are also the same — 2,000 IU/d — and
      are based on their selective focus on one flawed study; ample new
      data from well-conducted clinical trials support raising the upper
      limit to 10,000 IU. The 1997 FNB recommendations offend the most
      basic principles of pharmacology and toxicology, leading us to
      conclude that the current official guidelines and limitations for
      vitamin D intakes are scientifically indefensible."

      Cannell JJ, Vieth R, Willett W, Zasloff M, Hathcock JN, White JH,
      Tanumihardjo SA, Larson-Meyer DE, Bischoff-Ferrari HA, Lamberg-
      Allardt CJ, Lappe JM, Norman AW, Zittermann A, Whiting SJ, Grant WB,
      Hollis BW, Giovannucci E. Cod liver oil, vitamin A toxicity,
      frequent respiratory infections, and the vitamin D deficiency
      epidemic. Ann Otol Rhinol Laryngol. 2008 Nov;117(11):864-70.

      Are these statements the reason the IOM exluded these vitamin D
      experts? Perhaps the IOM dislikes criticism more than they love
      candor? When the new FNB vitamin D recommendations come out next
      summer, will those recommendations continue to "offend the most
      basic principles of pharmacology and toxicology?" If any member of
      the new board disagrees with the consensus of the board, will that
      scientist be allowed to produce a minority opinion without risking
      the loss of research grants in the future?

      Please take time to tell the IOM your thoughts. Tell them about
      your personal experience with vitamin D; how vitamin D affected your
      life and your health and the dose needed to do that.
