Vitamin D is actually a hormone that has many important functions to your overall health so it’s vital to know what your levels are.  I’m going to post highlights from some of the published studies shown at the bottom of this page.


  • Optimal levels of 60-80 ng/mL is based on the reports done by Dr. Stasha Gominak M.D. a Neurologist on over 5000 patients. It has been a very consistent observation for more than 7 years of testing. Most patients test an average of 3-4 times per year in order to keep their sleep and health at its best.



  • Of note: Canadian researchers reviewed 14 studies involving 31,424 participants and found a strong correlation between depression and a lack of Vitamin D. The lower the Vitamin D level, the greater the chance of depression.


  • Darker skinned people have a harder time converting UVB rays into Hormone D.  Melanin reduces the penetration of UVB and thus contributes to vitamin D insufficiency in individuals with darker skin.  High prevalence of vitamin D deficiency is present in all races, even in temperate areas, and is particularly high among Black Americans. A recent survey found, for example, that 42% of Black women had seriously deficient 25(OH)D levels (< 15 ng/mL)


  • Emerging health disparities data regarding African American and homeless populations suggest that vitamin D insufficiency (VDI) may be an underlying driver of COVID-19 severity. To better define the VDI-COVID-19 link, we determined the prevalence of VDI among our COVID-19 intensive care unit (ICU) patients.


  • Methods: In an Institutional Review Board approved study performed at a single, tertiary care academic medical center, the medical records of COVID-19 patients were retrospectively reviewed. Subjects were included for whom serum 25-hydroxycholecalcifoerol (25OHD) levels were determined. COVID-19-relevant data were compiled and analyzed. We determined the frequency of VDI among COVID-19 patients to evaluate the likelihood of a VDI-COVID-19 relationship.


  • Results: Twenty COVID-19 patients with serum 25OHD levels were identified; 65.0% required ICU admission. The VDI prevalence in ICU patients was 84.6%, vs. 57.1% in floor patients. Strikingly, 100% of ICU patients less than 75 years old had VDI. 8% were between 20-30 ng/mL, 65% had levels below 20 ng/mL and 27% below 10 ng /mL Coagulopathy was present in 62.5% of ICU COVID-19 patients, and 92.3% were lymphocytopenic.


  • Conclusions: VDI is highly prevalent in severe COVID-19 patients. VDI and severe COVID-19 share numerous associations including hypertension, obesity, male sex, advanced age, concentration in northern climates, coagulopathy, and immune dysfunction. Thus, we suggest that prospective, randomized controlled studies of VDI in COVID-19 patients are warranted.


  • Hormone D is made from the sun UVB light. When your skin is exposed to sunlight, it makes vitamin D from cholesterol. The sun’s ultraviolet B (UVB) rays hit cholesterol in the skin cells, providing the energy for vitamin D synthesis to occur.  There is no UVB light in the winter months.


  • What you will need to have, in order to use vitamin D safely, is a blood test called the vitamin D3 25 OH blood level. In the past our vitamin D blood level fluctuated with the seasons, high in summer, low in winter. Because humans are hairless we developed our own sunscreen (melanin) to block the sun and the formation of D. In the summer, as we stay in the sun day after day we make vitamin D but we also make a tan, which blocks the formation of more D, regulating the amount we make.


  • Most people can make 20,000 IU of vitamin D on a summer day, lying by the pool in a bathing suit. Darker-skinned people need longer sun exposure to make the same amount of D. There are break- down processes in the skin that prevent the D blood level from rising above 80 ng/ml from just sun exposure. So that level appears to be the “natural” upper limit. Supplementing vitamin D as a pill can easily take the D blood level above 80 ng/ml and it turns out that a D level over 80 usually makes sleep worse.


  • The association of living at upper (and lower) latitudes (i.e., above or below the 35th parallels of latitude) with increased risk of dying from cancer, type 1 diabetes, multiple sclerosis and hypertension is well documented.  It has been assumed that living beyond the temperate zone at higher latitudes increases risk of vitamin D deficiency because of decreased sun exposure on account of longer winters and the angle of sun, which is such that there is decreased ultraviolet B radiation. It is also recognized that every tissue and cell in the body including immune, brain, colon, prostate, and breast cells, among many others, have a vitamin D receptor (VDR).


  • Your Vitamin D blood level it should be tested by using D3 25 OH, (LCMS technique, not immunoassay) and not the D 1,25 OH level.


  • Vitamin D status differs by latitude and race, with residents of the northeastern United States and individuals with more skin pigmentation being at increased risk of deficiency. A PubMed database search yielded 63 observational studies of vitamin D status in relation to cancer risk, including 30 of colon, 13 of breast, 26 of prostate, and 7 of ovarian cancer, and several that assessed the association of vitamin D receptor genotype with cancer risk.

    The majority of studies found a protective relationship between sufficient vitamin D status and lower risk of cancer. The evidence suggests that efforts to improve vitamin D status, for example by vitamin D supplementation, could reduce cancer incidence and mortality at low cost, with few or no adverse effects.


  • The findings of the clinical trial, published today in the Journal of the American Geriatrics Society, could help reduce one of the leading causes of serious illness, debilitation and death among patients in nursing homes and other long-term care facilities. “After studying these patients for a year, we found a 40 percent reduction in acute respiratory illness among those who took higher doses of vitamin D,” said the study’s lead author, Adit Ginde, MD, MPH, professor of emergency medicine at the University of Colorado School of Medicine.


  • “Vitamin D can improve the immune system’s ability to fight infections because it bolsters the first line of defense of the immune system.”Ginde said in older people that first line of defense is often impaired. But vitamin D can reinforce it and prevent illnesses like pneumonia, influenza and bronchitis.






  • Patients diagnosed with any of the Vitamin D related diseases (cancer, diabetes, hypertension, heart disease, multiple sclerosis, systemic lupus erythematosus, depression, Alzheimer’s, Parkinson’s, epilepsy, and other others)

  • Patients with osteoporosis or rickets

  • Persistent and nonspecific musculoskeletal pain

  • Signs of depression or lack of energy

  • Patients with gastrointestinal disease and/or who have had a cholecystectomy

  • Elderly individuals

  • Overweight individuals with a BMI >25

  • Infants that are exclusively breastfed or children without a well-balanced diet

  • Individuals taking Vitamin D supplementation greater than 50 mcg (2,000 IUs) per day

  • Individuals that reside above 42 degrees north latitude (a line approximately between the northern border of California and Boston)

  • Individuals with medium to dark complexions or who do not regularly receive 20 minutes of direct sunlight each day

  • Patients having problems sleeping
