Poor Vitamin D Binding Protein is more associated with dark skin than Heart Disease
Wonder how many of the participants in this study had dark skin
- Vitamin D-binding protein and vitamin D status of black Americans and white Americans – Nov 2013
- Bioavailable Vitamin D is the same blacks and whites, but measured vit D is not – Oct 2014
- Blacks have lower vitamin D levels, but OK active vitamin D levels (VDBP) - Feb 2015

Vitamin D blood test misses a lot
- Snapshot of the literature by Vitamin D Life 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 Vitamin D Life took action with clues #3&4

Objective—To comprehensively evaluate the independent associations and potential interactions of vitamin D–related biomarkers including total and bioavailable 25-hydroxyvitamin D (25OHD), VDBP (vitamin D binding protein), and parathyroid hormone (PTH) with risk of coronary heart disease (CHD).
Approach and Results—We prospectively identified incident cases of nonfatal myocardial infarction and fatal CHD among women in the Nurses’ Health Study during 20 years of follow-up (1990–2010). Using risk-set sampling, 1 to 2 matched controls were selected for each case. The analysis of 25OHD and PTH included 382 cases and 575 controls; the analysis of VDBP included 396 cases and 398 controls. After multivariate adjustment, plasma levels of total 25OHD, bioavailable 25OHD, and PTH were not significantly associated with CHD risk.
VDBP was associated with a lower CHD risk with an extreme-quartile odds ratio of 0.60 (95% confidence interval, 0.39–0.92; P trend=0.02). When examining the biomarkers jointly, a significant, inverse association between 25OHD and CHD was observed among participants with higher PTH levels (P for interaction=0.02).
The odds ratio (95% confidence interval) comparing the highest quartile of 25OHD to lowest was 0.43 (0.23–0.82; P trend=0.003) when PTH levels were above population median (35.3 pg/mL), whereas among the rest of participants the corresponding odds ratio (95% confidence interval) was 1.28 (0.70–2.36; P trend=0.43).
Conclusions—Our data suggest that higher 25OHD levels were associated with a lower CHD risk when PTH levels were high, whereas no association was observed for participants with low PTH levels. VDBP but not bioavailable 25OHD was independently associated with lower CHD risk.
