Vitamin D blood test misses a lot
- 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 shows benefits (even if conventional Vitamin D test shows an increase)
3) DNA and VDR tests - 100 to 200 dollars $100 to $250
4) PTH bottoms out ( shows that parathyroid cells are getting Vitamin d)
Genes are good, have enough Magnesium, etc.
5) 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&5

Vitamin D Receptor category has the following
530 studies in Vitamin D Receptor category Vitamin D tests cannot detect Vitamin D Receptor (VDR) problems
See also:
A poor VDR restricts Vitamin D from getting in the cells48 studies in the Resveratrol category It appears that 30% of the population have a poor VDR (40% of the Obese )
Health problems include: Autoimmune (
Several diseases protect themselves by deactivating the Vitamin D receptor. Example: Breast Cancer
- - - - - - - -
The Vitamin D Receptor is associated with many health problems19 studies), Breast Cancer ( 24 studies), Colon Cancer ( 13 studies), Cardiovascular ( 23 studies), Cognition ( 16 studies), Diabetes ( 24 studies), Hypertension ( 9 studies), Infant ( 22 studies), Lupus ( 6 studies), Metabolic Syndrome ( 4 studies), Mortality ( 4 studies), Multiple Sclerosis ( 14 studies), Obesity ( 17 studies), Pregnancy ( 24 studies), Rheumatoid Arthritis ( 10 studies), TB ( 8 studies), VIRUS ( 37 studies), Click here for details
Some health problems, such as Breast Cancer, Diabetes, and COVID protect themselves by reducing VDR activation
55 health problems associated with poor VDR
A poor VDR is associated with the risk of 55 health problems click here for details
The risk of 48 diseases at least double with poor VDR as of Jan 2023 click here for details
Some health problem, such as Breast Cancer reduce the VDRVDR at-home test $29 - results not easily understood in 2016
There are hints that you may have inherited a poor VDR
How to increase VDR activation
Compensate for poor VDR by increasing one or more:Increasing Increases 1) Vitamin D supplement Sun
Ultraviolet -BVitamin D in the blood
and thus in the cells2) Magnesium Vitamin D in the blood
AND in the cells3) Omega-3 Vitamin D in the cells 4) Resveratrol Vitamin D Receptor 5) Intense exercise Vitamin D Receptor 6) Get prescription for VDR activator
paricalcitol, maxacalcitol?Vitamin D Receptor 7) Quercetin (flavonoid) Vitamin D Receptor 8) Zinc is in the VDR Vitamin D Receptor 9) Boron Vitamin D Receptor ?,
etc10) Essential oils e.g. ginger, curcumin Vitamin D Receptor 11) Progesterone Vitamin D Receptor 12) Infrequent high concentration Vitamin D
Increases the concentration gradientVitamin D Receptor 13) Sulfroaphane and perhaps sulfur Vitamin D Receptor 14) Butyrate especially gut Vitamin D Receptor 15) Berberine Vitamin D Receptor Note: If you are not feeling enough benefit from Vitamin D, you might try increasing VDR activation. You might feel the benefit within days of adding one or more of the above
Far healthier and stronger at age 72 due to supplements Includes 6 supplements that help the VDR
13 reasons why many seniors need more vitamin D (both dose and level) - July 2023 has the following- Senior skin produces 4X less Vitamin D for the same sun intensity
- Seniors have fewer vitamin D receptor genes as they age
Receptors are needed to get Vitamin D in blood actually into the cells - Many other Vitamin D genes decrease with age
- Since many gene activations are not detected by a blood test,
more Vitamin D is often needed, especially by seniors - Seniors are indoors more than when they were younger
not as agile, weaker muscles; frail, no longer enjoy hot temperatures - Seniors wear more clothing outdoors than when younger
Seniors also are told to fear skin cancer & wrinkles - Seniors often take various drugs which end up reducing vitamin D
Some reductions are not detected by a vitamin D test of the blood
statins, chemotherapy, anti-depressants, blood pressure, beta-blockers, etc - Seniors often have one or more diseases that consume vitamin D
osteoporosis, diabetes, Multiple Sclerosis, Cancer, ... - Seniors generally put on weight as they age - and a heavier body requires more vitamin D
- Seniors often (40%) have fatty livers – which do not process vitamin D as well
- Reduced stomach acid means less Magnesium is available to get vitamin D into the cells
- Vitamin D is not as bioavailable in senior intestines
- Seniors with poorly functioning kidneys do not process vitamin D as well
- Glutathione (which increases Vitamin D getting to cells) decreases with age

Osteoporosis is characterized by low bone mass and microarchitecture deterioration of bone tissue, leading to enhanced bone fragility and consequent increase in fracture risk. Evidence is accumulating for an important role of calcium deficiency as the process of aging is associated with disturbed calcium balance. Vitamin D is the principal factor that maintains calcium homeostasis. Increasing evidence indicates that the reason for disturbed calcium balance with age is inadequate vitamin D levels in the elderly. In this article, an overview of our current understanding of vitamin D, its metabolism, and mechanisms involved in vitamin D-mediated maintenance of calcium homeostasis is presented.
In addition, mechanisms involved in age-related dysregulation of 1,25(OH)2D3 action, recommended daily doses of vitamin D and calcium, and the use of vitamin D analogs for the treatment of osteoporosis (which remains controversial) are reviewed. Elucidation of the molecular pathways of vitamin D action and modifications that occur with aging will be an active area of future research that has the potential to reveal new therapeutic strategies to maintain calcium balance.PMID: 27790378 DOI: 10.1038/boneres.2016.41

- “We and others have noted that renal CYP24A1, which limits the amount of 1,25 (OH)2D3 by accelerating the catabolism of 1,25(OH)2D3, increases with age.”
- “In addition, with age there is a defect in 1 α hydroxylation.”
- . . “there is also an age-related decrease in renal VDR and TRPV5 expression with age,” . .
- “Some individuals, however, do not respond to vitamin D supplementation with an increase in 25(OH)D. The factors controlling this lack of response are unknown.”
