Can Vitamin D Lower Covid Risk? — Dr. David Meltzer shares findings from his study on the show “The Doctors”
Today, we are sharing another video in which Dr. Ian Smith of the show The Doctors interviews Dr. David Meltzer from the University of Chicago about the findings of his recent study, which found that patients who had tested vitamin D deficient (less than 20 ng/ml or 50 nmol/L) were about 77% more likely to test positive for COVID-19 than patients whose vitamin D level was not deficient.
Our hope is for you to share this quick video clip along with our responses and details below with those around you and those who are in places of making a difference, to further the education about vitamin D and its role in helping to protect against COVID-19, and the steps to take to ensure a healthy vitamin D level.

After watching the video, be sure to make note of our added details below!
Can Vitamin D Lower Covid Risk?
Here is a quick summary of what this video discusses, along with additional information and details about vitamin D:
- Vitamin D is a hormone – but it is important not to exclude its role as a vitamin or nutrient and what is called a signaling molecule
- Vitamin D may be most well-known for its role in bone health, however it also helps to enhance immune and inflammatory responses – there are many ways vitamin D is involved in the immune response, from increasing white blood cells to fighting infection, modulating the expression of immune regulating genes, and decreasing inflammation
- Dr. Meltzer’s recent study found that vitamin D deficient people (whose vitamin D level had tested below 20 ng/ml or 50 nmol/L within the past year) were 77% more likely to test positive for COVID-19 than those who were not deficient
- An earlier study mentioned showed a 70% lower incidence of viral respiratory tract infections among those who had been vitamin D deficient but were randomly assigned to take vitamin D, compared to those who did not receive vitamin D – some infections in this study were likely due to a coronavirus infection
- At least half of the population does not have enough vitamin D!
- Sunlight can be a source of vitamin D – however, several factors influence if and how much vitamin D you can make from sun, including where you live, time of day, season, skin color, clothing and sunscreen. Always important to remember not to burn!
- Can you take too much vitamin D? Toxicity is very rare and difficult to achieve. The current RDA of 600-800 IU per day is way too low. 4,000 IU per day is considered safe, however, may not be enough for many to reach the scientists’ recommended 40-60 ng/ml (100-150 nmol/L) vitamin D level.
What does the Research Say about Vitamin D & COVID-19?
It’s TIME to start saving lives! If you can help PREVENT the majority of the death, it’s time! What’s it costing you/us not to take action NOW?
There is much published research that supports a clear link between vitamin D and COVID-19 showing that higher vitamin D levels are related to:
Be sure to educate yourself on the benefits and importance of vitamin D for immune health, and take steps to ensure you and your loved ones are getting enough.

What Does it Take YOU to Get Your D to 40 ng/ml (100 nmol/L)?Did you know your health could be greatly affected by making sure you have a vitamin D level of at least 40 ng/ml (100 nmol/L)? Help us help you.
STEP 1 - Do you know what your vitamin D level is? If not, be sure to test today to find out.
STEP 2 – Determine your target level. Are you at your target level? Experts recommend a level of at least 40-60 ng/ml (100-150 nmol/L).
STEP 3 – Need to boost your level? Use the D*calculator to see how much vitamin D it may take to reach your target. Opt for the Loading Dose for a quicker boost.
STEP 4 – Optimize how your body absorbs and utilizes vitamin D with co-nutrients and these simple steps.
STEP 5 – Re-Test! This is an important step to make sure you have reached your target level, and to ensure you are not taking too much! Re-testing after 3-4 months is recommended.
STEP 6 – Adjust, Repeat…
Give your immune system the nutrients it needs to support a healthy you and protect yourself from unnecessary diseases, especially COVID-19.
The first Randomized Controlled Trial on vitamin D and COVID-19 has shown a 96% lower risk of ICU admission for those receiving vitamin D (as 25(OH)D to quickly boost vitamin D blood levels) along with the standard treatment, compared to those receiving standard treatment alone.
These results support many previous observational studies showing a relationship between vitamin D levels and intake and COVID-19 severity.
GrassrootsHealth Nutrient Research Institute has launched the new Immune Boost project with the use of our myData-myAnswers nutrient health system that nearly 15,000 people are already using for their health. Specific markers that influence immune health are suggested for testing as part of this project including:
- Vitamin D
- Omega-3 Index
- Essential elements magnesium, selenium, and zinc
Our goal is to demonstrate how one can use the Nutrient Research Model established by Dr. Robert Heaney to show the effect of vitamin D serum levels of at least 40 ng/ml (100 nmol/L) on risk reduction for all ethnicities in the population. Status and intake of other nutrients will also be analyzed for any type of relationship to immune status and symptom severity. Join the project today!
Please let us know if you're interested in helping sponsor this project.
Through GrassrootsHealth Nutrient Research Institute, you can also test your essential elements magnesium, copper, zinc and selenium, toxins such as lead, mercury and cadmium, as well as your omega-3 levels, inflammation levels and thyroid stimulating hormone (TSH) level. Find out your levels today! Log on to the test selection page (click the link below) to get your tests and see for yourself if your levels can be improved.
Make sure you track your results before and after, about every 6 months!
How can I track my nutrient intake and levels over time?
To help you track your supplement use and nutrient levels, GrassrootsHealth has created the Personal Health Nutrient Decision System called
For each specific supplement, you can track what days you take it, how much, and many other details. This will help you know your true supplemental intake and what patterns of use work for you to reach and maintain optimum nutrient levels. Check it out today!
