- Test your vitamin D level today!
Vitamin D intake and status has repeatedly been shown to help predict or influence COVID-19 disease risk and outcomes. In fact, many studies have now demonstrated that COVID-19 disease tends to have a more severe course in patients with vitamin D deficiency, and that correcting deficiency, even after diagnosis, can help protect against death.
Simply put, vitamin D status is a major and easily modifiable factor that has been shown to reduce the incidence of COVID-19 and improve disease outcomes.

700,000 Covid-19 Deaths: Time for a Change in Treatment Strategy
Commentary by Dwight K. Kalita, Ph.D.
OMNS (Oct. 17, 2021) Tragically, there have been over 700,000 Covid-19 deaths in the United States. Perhaps it is time to consider that in addition to drug therapies, physicians in the United States might also want to use treatments that are based on optimum nutritional support for their patients. For example, in Spain, physicians are treating their Covid-19 patients with high doses of vitamin D, and they have discovered some amazing results. A 76-patient 2020 study in October 2020 discovered that of 50 hospitalized COVID-19 patients who were given oral calcifediol: (0.532 mg, ~20,000 IU, on admission and 0.266 mg, ~10,000 IU, several days thereafter) of vitamin D, only one (2%) needed treatment in the intensive care unit and there were no deaths. In contrast, among the 26-remaining COVID-19 patients who were not given vitamin D, 13 (50%) needed to be treated in the intensive care unit and two died. 
Obviously, if vitamin D is given in an optimum dose as well as for an effective period of time, it has potent immune-boosting powers to potentially fight off severe viral respiratory symptoms and even death associated with Covid-19. If it is not given, the results are far more troubling and deadly.
It is important to understand that if you are deficient in vitamin D, that does impact your susceptibility to viral infections as well as your ability to fight them. In fact, a 2021 study of 65 Covid-19 patients compared to a control group concluded that “a vitamin D serum deficiency is associated with more severe lung involvement, longer disease duration and risk of death.” 
Regrettably, measurable nutritional deficiencies do indeed exist in Covid-19 patients. For example, in a February, 2021 study of 227 patients who were hospitalized with Covid-19, 102 (45%) had catastrophically depleted vitamin D levels of 12 ng/mL or lower.  Vitamin D blood levels should range between 30-70 ng/mL. Some physicians believe that a level between 50-60 ng/mL is optimal. Hence, these 102 Covid-19 patients had extremely low, rickets-inducing vitamin D blood levels. In this same study, a whopping 213 (94%) of them had significantly depleted levels of vitamin D below 30 ng/mL. 
Unfortunately, about 42% of the US population is vitamin D deficient. And 60% of nursing home residents as well as 76% of African Americans are deficient in this essential immune-boosting nutrient. Needless to say, all physicians should be testing all of their Covid-19 patients for this particular nutrient deficiency. And if their Covid-19 patients are vitamin D deficient, they should be treating them accordingly. Based on the previously mentioned statistics, to do otherwise would be negligent.
In his book Biochemical Individuality, Roger Williams, Ph.D. explains that we all have unique nutritional requirements.  In order for everyone to maintain an optimum blood level of vitamin D, professional testing and additional supplements might be advised. As a nutrition / medical writer for over 40 years, I have learned that many people, including some doctors, are unaware of the important and life-saving link between vitamin D and our susceptibility to viral infections as well as our ability to fight them. Accordingly, it is time for all physicians to realize the very powerful treatment benefits of this essential, often deficient, relatively inexpensive, readily available, and immune-boosting nutrient which Mother Nature has given to us.

How Can You Use this Information for YOUR Health?
Having and maintaining healthy vitamin D and other nutrient levels can help improve your health now and for your future. Measuring is the only way to make sure you are getting enough!
STEP 1 Order your at-home blood spot test kit to measure vitamin D and other nutrients of concern to you, such as omega-3s, magnesium, essential and toxic elements (zinc, copper, selenium, lead, cadmium, mercury); include hsCRP as a marker of inflammation or HbA1c for blood sugar health
STEP 2 Answer the online questionnaire as part of the GrassrootsHealth study
STEP 3 Using our educational materials and tools (such as our dose calculators), assess your results to determine if you are in your desired target range or if actions should be taken to get there
STEP 4 After 3-6 months of implementing your changes, re-test to see if you have achieved your target level(s)
