Highlights of Vitamin D Wiki

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.

Kidney

Overview Kidney and vitamin D contains the following summary

• FACT: The Kidneys are not the primary way to activate vitamin D, the tissues are
• FACT: When the Kidney has problems, there is less active vitamin D (Calcitriol) for the body
• FACT: When the Kidney has problems, there is increased death due to many factors - many of which are associated with lack of Calcitriol
• FACT: There are many on-going intervention clinical trials trying to determine how much of what kind of vitamin D is needed to treat the problem
• FACT: One Randomized Controlled Trial has proven that Vitamin D treats CKD
• FACT: 38% of seniors have Chronic Kidney Disease and most are unaware of it CDC statistics 2020
• FACT: Taking extra Vitamin D, in various forms, does not cause health problems - even if poor kidney
• Suggestion: Increase vitamin D getting into body now - and increase co-factors so that the vitamin D can be better used
    Sun, UV lamp, Vitamin D supplement - probably > 5,000 IU,
  Calcitriol - which bypasses the need for the kidney to activate vitamin D
    Problems with Calcitriol however: typically only lasts for a few hours, also, possible complications

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
   • (The effect of low Vitamin D receptor genes does not show up on vitamin D test results)
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 **+fear skin cancer/wrinkles, sometimes avoid bright light after cataract surgery
5. Seniors often take various drugs which reduce vitamin D (some would not show up on vitamin D test) statins, chemotherapy, anti-depressants, blood pressure, beta-blockers, etc
6. Seniors often have one or more diseases which consume vitamin D ( osteoporosis, diabetes, MS, ...)
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. Seniors not have as much Magnesium needed to use 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?)

 Infants-Child

Infant-Child category starts with

• No consensus on MINIMUM International Units (IU) for healthy infant of normal weight
• 400 IU Vitamin D is no longer enough
  Was OK in the past century, but D levels have been dropping for a great many reasons.
  FDA doubled the vitamin D level in milk in July 2016
• No consensus: range is 600 to 1600 IU – based on many randomized controlled trials
• Review of 400 IU to 2000 IU daily and higher if non-daily
• Fewer pre-infants were vitamin D deficient when they got 800 IU – RCT Feb 2014
• 1600 IU was the conclusion of three JAMA studies
     1000 IU recommended in France and Finland – 2013 - appears to be a good level
• 5X less mite allergy after add vitamin D
• Child bone fractures with low vitamin D were 55X more likely to need surgery
• 75 % of SIDS had low vitamin D
• Children stayed in ICU 3.5 days longer if low vitamin D – Dec 2015
• 5 out of 6 children who died in pediatric critical care unit had low vitamin D – May 2014

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

• Asthma, Chronic illness, Doctor visits, Allergies, infection
  Respiratory Tract Infection, Growing pains, Bed wetting

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.
  
  More than 100 IU/kg is probably better

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

Vitamin D supplementation

Amount of vitamin D needed vs:

More vitamin D needed -nutshell category has the following

Age	Latitude	Season
Obesity	Skin color	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:

• 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.

Loading Dose - to get the benefit as soon as possible

Overview Loading of vitamin D contains the following

Loading dose: 175 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
   in a nutshell = summed up = condensed

Supplements categories in VitaminDWiki include

Supplement	# of studies		Increase D to tissue
Omega-3	349	Many benefits	30%?

Magnesium

• 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 271 items

Omega-3

• 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 349 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 131 items

Calcium

• 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 201 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 69 items

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

• The cost of cofactors is 10X to 100X more than the vitamin D when taken as pills
• Bulk supplementation of Vitamin D, Magnesium, Zinc, B-12, K2, Boron etc. - lower cost and easier than pills
  • just 40 cents per day as a powder
• Many of the cofactors need be taken daily (vs Vitamin D can be taken weekly or bi-weekly)

Genes can restrict Vitamin D from getting to the cells

Even if vitamin D levels are OD (e.g. > 40 nanogram)
Genetics category listing contains the following

282 articles in the Genetics category

• 147 articles in Vitamin D Binding Protein = GC

Vitamin D blood test misses a lot

• Snapshot of the literature by VitaminDWiki as of early 2019
• 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
  • especially if it is one of 51+ diseases related to Vitamin D Receptor
  
  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
  
  4) Back Pain
  • probably want at least 2 clues before taking adding vitamin D, Omega-3, Magnesium, Resveratrol, etc
    • The founder of VitaminDWiki took action with clues #3&4
