Overview of VitaminDWiki

Although researchers, physicians, and clinical nutritionists can't agree completely on dose rates, recommended blood levels, and expected clinical outcomes, there is no question that vitamin D status plays an important role in reducing, preventing, and in some cases, treating a wide range of chronic degenerative medical conditions. The purpose of the VitaminDWiki is to provide a convenient, comprehensive, and authoritative resource to investigate how optimizing vitamin D status may be helpful for you or someone you care about. It's a big subject so we urge you to spend some time exploring and learning about this important nutrient.

Overview Diabetes and vitamin D appears to be due to a lack of Vitamin D

  • Diabetes is 5X more frequent far from the equator
  • Children getting 2,000 IU of vitamin D are 8X less likely to get Type 1 diabetes
  • Obese people get less sun / Vitamin D - and also vitamin D gets lost in fat
  • Sedentary people get less sun / Vitamin D
  • Worldwide Diabetes increase has been concurrent with vitamin D decrease and air conditioning
  • Elderly get 4X less vitamin D from the same amount of sun
        Elderly also spend less time outdoors and have more clothes on
  • All items in category Diabetes and Vitamin D 510 items: both Type 1 and Type 2

Vitamin D appears to both prevent and treat diabetes

  • Appears that >2,000 IU will Prevent
  • Appears that >4,000 IU will Treat , but not cure
  • Appears that Calcium and Magnesium are needed for both Prevention and Treatment
    • which are just some of the vitamin D cofactors

Overview Osteoporosis and vitamin D contains the following summary

  • FACT: Bones need Calcium (this has been known for a very long time)
  • FACT: Vitamin D improves Calcium bioavailability (3X ?)
  • FACT: Should not take > 750 mg of Calcium if taking lots of vitamin D (Calcium becomes too bio-available)
  • FACT: Adding vitamin D via Sun, UV, or supplements increased vitamin D in the blood
  • FACT: Vitamin D supplements are very low cost
  • FACT: Many trials, studies. reviews, and meta-analysis agree: adding vitamin D reduces osteoporosis
  • FACT: Toxic level of vitamin D is about 4X higher than the amount needed to reduce osteoporosis
  • FACT: Co-factors help build bones.
  • FACT: Vitamin D Receptor can restrict Vitamin D from getting to many tissues, such as bones
  • It appears that to TREAT Osteoporosis:
  •        Calcium OR vitamin D is ok
  •        Calcium + vitamin D is good
  •        Calcium + vitamin D + other co-factors is great
  •        Low-cost Vitamin D Receptor activators sometimes may be helpful

Groups typically needing more Vitamin D

Seniors need more vitamin D - 10 reasons

  1. Senior skin produces 3X less Vitamin D for the same sun intensity
  2. Seniors have fewer vitamin D receptors as they age
  3. Seniors are indoors more than than when they were younger
    • not as agile, weaker muscles; frail, no longer enjoy hot temperatures
    • (if outside, stay in the shade), however, seniors might start outdoor activities like gardening, biking, etc.
  4. Seniors wear more clothing outdoors than when younger
    • Seniors also are told to fear skin cancer/wrinkles
  5. Seniors often take various drugs which reduce vitamin D
  6. Seniors often have one or more diseases which consume vitamin D
  7. Seniors generally put on weight at they age - and a heavier body requires more vitamin D
  8. Seniors often (40%) have fatty livers – which do not process vitamin D as well
  9. Reduced stomach acid ==>less Magnesium needed to utilize vitamin D
    (would not show up on vitamin D test)
  10. Seniors with poorly functioning kidneys do not process vitamin D as well
    (would not show up on vitamin D test) 2009 full text online  Also PDF 2009
  11. Vitamin D is not as bioavailable in senior digestive systems (Stomach acid or intestines?)


Infant-Child category starts with

Having a good level of vitamin D cuts in half the amount of:

Need even more IUs of vitamin D to get a good level if;

  • Have little vitamin D: premie, twin, mother did not get much sun access
  • Get little vitamin D: dark skin, little access to sun
  • Vitamin D is consumed faster than normal due to sickness
  • Older (need at least 100 IU/kilogram, far more if obese)
  • Not get any vitamin D from formula (breast fed) or (fortified) milk
    Note – formula does not even provide 400 IU of vitamin D daily

Infants-Children need Vitamin D

  • Sun is great – well known for 1,000’s of years.
    US govt (1934) even said infants should be out in the sun
  • One country recommended 2,000 IU daily for decades – with no known problems
  • As with adults, infants and children can have loading doses and rarely need tests
  • Daily dose appears to be best, but monthly seems OK
  • Vitamin D is typically given to infants in the form of drops
       big difference in taste between brands
       can also use water-soluable form of vitamin D in milk, food, juice,
  • Infants have evolved to get a big boost of vitamin D immediately after birth
    Colostrum has 3X more vitamin D than breast milk - provided the mother has any vitamin D to spare
  • 100 IU per kg of infant July 2011, Poland etc.
    1000 IU per 25 lbs.jpg
    More than 100 IU/kg is probably better

Did you know that:

Getting Vitamin D into infants
Many infants reject vitamin D drops, even when put on nipple
I speculate that the rejection is due to one or more of: additives, taste, and oils.
Infants have a hard time digesting oils, 1999  1997   and palm oils W.A. Price 1 2 3
Coconut oil, such as in D-Drops, is digested by infants. 1,   2   3
Bio-Tech Pharmacal Vitamin D has NO additves, taste, nor oil
One capsule of 50,000 Bio-Tech Pharmacal Vitamin D could be stirred into monthly formula or given once a month
   this would result in ~1,600 IUs per day for infant, and higher dose with weight/age/formula consumption

Avoid Sun

Supplementation from Zika book (July 20, 2016)

Vitamin D Recommendations: based on hundreds of successful Vitamin D studies (with/without pregnancy)

  • 4,000 IU daily average minimum amount of Vitamin D
    Similar dosing is 50,000 IU bi-weekly (Daily is probably slightly better)
    It is 1/3 the cost and easier to remember than daily dosing.
    Note: Taking vitamin D also increases chance of pregnancy
  • More is needed if likely to have very low levels of vitamin D:
    6,000 IU daily average if:
    • having twins or had a recent birth,
    • health problems associated with low vitamin D
    • indoors a lot or avoid the sun
    • dark skin

    10,000 IU (50,000 IU every 5th day) if:
    • Obese


  • Normal weight     Obese     (50 ng = 125 nanomole)

Click here for 2014 obesity study

    • if diseases run in the family
  • May want to restore levels as quickly as possible with 350,000 IU loading dose
    during pregnancy, especially if there is the threat of Zika
    this gets a strong immune system quickly, not with months of delay using a daily maintenance dose
    • 50,000 IU daily for 1 week if not pregnant
    • 50,000 IU every second day for 2 weeks if pregnant
  • Start ASAP during pregnancy (even before) so as to both avoid Zika and have healthy pregnancy and infant
  • Should use a vitamin D which has no known adverse affects
    No additives, no oils (30% of oil-based Vit D which restrict vitamin D adsorption)
  • Most people (80%?) can take regular vitamin D capsules
    Options if:
    • Not want to take pills – use liquid Vitamin D or pour vitamin D powder from capsule into food/drink
    • Poor gut – several “gut friend” forms are available
    • Vegan – several forms of Vitamin D3 are made from plants such as lichen
    • Halal, Kosher, etc.
  • Magnesium Cofactor 100+ miligrams of element daily – tell why especially during pregnancy
    • Increases the benefits of vitamin D
    • Decreases chance of allergic-type reaction to Vitamin D (from ~ 3 in 1000 to 1 in 1000)
  • Omega-3 Cofactor
  • Vitamin K2 cofactor
  • Test for Vitamin D is nice but very expensive ($60) and not really essential
  • Take vitamin D just after evening meal
    • about~30% more benefit with evening meal, but most anytime is OK
  • Just concerned about average vitamin D during a 2 week time period
    4,000 IU taken daily is virtually identical to 50,000 IU once every two weeks
    OK to have missed your dose for a few days - just take nissed once all at once.

How often should I take 50,000 IU

How often should I take 50000 IU (1.25 mg) of vitamin D

10 minutes of sun not enough

No – 10 minutes per day of sun-UVB is NOT enough

  • 5-10 minutes provides only 1,000 IU ONLY IF you are near the equator
  • AND young
  •  AND not obese
  •   AND have light skin
  •    AND it is summer
  •     AND it is the middle of the day
  •      AND you have lots of skin exposed to the sun
  •       AND you are lying down
  •        AND you are not wearing sunscreen
  •         AND you have a healthy Liver
  •          AND no clouds and nor air pollution
  •           AND you have good response to sunshine (4X variation between individuals)

Loading Dose - to get the benefit as soon as possible

Overview Loading of vitamin D contains the following

Loading dose: 189 studies at VitaminDWiki

Vitamin D loading dose (stoss therapy) proven to improve health overview
If a person is or is suspected to be, very vitamin D deficient a loading dose should be given

  • Loading = restore = quick replacement by 1 or more doses
  • Loading doses range in total size from 100,000 IU to 1,000,000 IU of Vitamin D3
    • = 2.5 to 25 milligrams
  • The size of the loading dose is a function of body weight - see below
    • Unfortunately, some doctors persist in using Vitamin D2 instead of D3
  • Loading may be done as quickly as a single day (Stoss), to as slowly as 3 months.
    • It appears that spreading the loading dose over 4+ days is slightly better if speed is not essential
  • Loading is typically oral, but can be Injection (I.M,) and Topical
  • Loading dose is ~3X faster if done topically or swished inside of the mouth
    • Skips the slow process of stomach and intestine, and might even skip liver and Kidney as well
  • The loading dose persists in the body for 1 - 3 months
    • The loading dose should be followed up with on-going maintenance dosing
    • Unfortunately, many doctors fail to follow-up with the maintenance dosing.
  • About 1 in 300 people have some form of a mild allergic reaction to vitamin D supplements, including loading doses
    • it appears prudent to test with a small amount of vitamin D before giving a loading dose
    • The causes of a mild allergic reaction appear to be: (in order of occurrence)
    • 1) lack of magnesium - which can be easily added
    • 2) allergy to capsule contents - oil, additives (powder does not appear to cause any reaction)
    • 3) allergy to the tiny amount of D3 itself (allergy to wool) ( alternate: D3 made from plants )
    • 4) allergy of the gut to Vitamin D - alternative = topical

Cofactors are important if you take a lot of vitamin D for a long time

Vitamin D Cofactors in a nutshell
!!!!Cofactors need to be adjusted when taking a lot of vitamin D for more than a month
"A lot" is more than 4,000 IU Vitamin D daily (average)
There is virtually no agreement as how much of each cofactor is needed vs vitamin D level
The first three cofactors have, like vitamin D, greatly decreased in the human diet in the past 50 years
The goal is to restore Vitamin D, Magnesium, Omega-3, and Vitamin K back to where they had been

  • About 1 in 300 people have a poor reaction to increasing Vitamin D
       but the Vitamin D reaction (muscle pain) is almost always due to lack of Magnesium
  • Magnesium increases the benefits of vitamin D by about 30% (Mg and Vit. D are synergistic)
  • Magnesium provides a great many health benefits independent of Vitamin D
    • Magnesium is used at 8 stages of Vitamin D metabolism
  • 100 milligrams of Magnesium (say from Magnesium Chloride) seems to be enough, even with high levels of vitamin D
    Some people (not a consensus) believe that only 100 mg of Mg can be taken up by the gut at a time
    If possible, take your Magnesium several times during the day - not just once
    • Vitamin D appears to consume Magnesium
    • People with > 100 ng of Vitamin D (and do not supplement with Mg) are 2.5X more likely to have A-fib
    • Constipation due to low Magnesium after greatly increasing Vitamin D level (personal experience of founder of VitaminDWiki)
  • Overview Magnesium     Magnesium category has 320 items


  • Omega-3 increases active vitamin D - especially in people with poorly functioning livers or kidneys
  • 1 gram of Omega-3 seems to be enough. Note: different brands have widely different bio-availability
  • Overview Omega-3     Omega-3 category has 371 items

Vitamin K2

  • K2 Keeps Calcium in bones and out of arteries
  • Calcification due to K2 deficiency may be a reason for increased mortality for some diseases for high vitamin D
  • Probably need 100 micrograms per 2,000 IU of vitamin D (i.e. 500 micrograms for 10,000 IU of Vit D)
    • Perhaps Vitamin D consumes Vitamin K, so need more of it
  • Vitamin D decreases the uptake of Vitamin K1 by 50%
    • Perhaps should not take K2 concurrently with Vitamin D.
  • Overview Vitamin K2     Vitamin K category has 140 items


  • Too much Calcium is associated with cardiovascular problems years later, not stronger bones
  • Should have less than 750 milligrams of Calcium supplementation
  • Drinking a lot of water helps flush any excess Calcium from the Kidneys
  • Overview Calcium     Calcium category has 213 items

Boron - good, but not as essential

  • Boron increases Vitamin D and Magnesium in the body by ~ 20%
  • Most people Boron deficient now that commercial fertilizers are used
  • Should have 3-10 milligrams of Boron element daily
  • Boron can be extremely low cost, less than $0.01 a day
  • Boron category has 30 items

Zinc - good, but not as essential

  • Extra Zinc does not appear to increase D in the blood. but may increase D in the tissue
  • Zinc is, however, essential to make Vitamin D Receptors and utilize Omega-3
  • Low zinc is associated with many autoimmune diseases,infections, colds, etc
  • Zinc, like Boron, is extremly low-cost and safe
  • Zinc category has 78 items

Unfortunately cofactors as pills are costly and typically need to be taken daily

Vitamin D blood test misses a lot
Blood Test Misses a lot (VDW 3439)

  • Vitamin D from coming from tissues (vs blood) was speculated to be 50% in 2014, and by 2017 was speculated to be 90%
  • Note: Good blood test results (> 40 ng) does not mean that a good amount of Vitamin D actually gets to cells
  • A Vitamin D test in cells rather than blood was feasible (2017 personal communication)
  •    Commercially available 2019
    • However test results would vary in each tissue due to multiple genes
  • Good clues that Vitamin D is being restricted from getting to the cells
    1) A vitamin D-related health problem runs in the family
    2) Slightly increasing Vitamin D show benefits (even if conventional Vitamin D test shows an increase)
    3) Vitamin D Receptor test (<$30) scores are difficult to understand in 2016
    • easier to understand the VDR 23andMe test results analyzed by FoundMyFitness in 2018
