Keep in mind that in order to have good VITAMIN D absorption it is important to take it with food and have good fats in the diet. See the videos and articles below for more information. Also, it is advisable to check the Vitamin D level in the blood at least once per year.

Vitamin D Is Important for Optimal Immune Function
In the video above, Dr. Roger Seheult reviews how vitamin D works, and the benefits of vitamin D, both for respiratory infections in general and as it pertains to COVID-19.
Importantly, vitamin D is a steroid hormone that can pass through cellular membranes into the nucleus and controls the expression of genes. So, it’s not just a mere vitamin required as a cofactor. It can actually modify how the cells in your body behave and function.
Vitamin D receptors are found in a large number of different tissues and cells, including your immune cells. This means vitamin D plays an important role in your immune function specifically. If vitamin D is lacking, your immune system will be impaired, which in turn makes you more susceptible to infections of all kinds. As noted by Seheult, vitamin D:
- Stimulates “the innate immune response, which provides frontline protection against infectious agents”
- Increases expression of antimicrobial peptides in your monocytes and neutrophils — both of which play important roles in COVID-19
- Enhances expression of an antimicrobial peptide called human cathelicidin, “which is of specific importance in host defenses against respiratory tract pathogens”
A growing body of evidence shows that vitamin D plays a crucial role in disease prevention and maintaining optimal health. There are about 30,000 genes in your body, and vitamin D affects nearly 3,000 of them, as well as vitamin D receptors located throughout your body.
For a more detailed and comprehensive analysis of the connection of vitamin D and COVID-19, please review the report I created that could be used to address any health care professionals who would disagree with this recommendation. Also included is a shortened version of the document which will be better to educate those that you would like to convince of the importance of getting your vitamin D levels optimized.
Vitamin D Helps Protect Against Cancer and Other Diseases
According to one large-scale study, having optimal vitamin D levels can slash your risk of cancer and can help prevent at least 16 different types of cancer, including pancreatic, lung, ovarian, prostate and skin cancers.
Vitamin D from sun exposure also radically decreases your risk of autoimmune diseases such as multiple sclerosis (MS) and Type 1 diabetes. Sun exposure also helps prevent osteoporosis, which is a significant concern for women in particular.
Magnesium Is Necessary to Activate Vitamin D
Since over half the population does not get enough magnesium and far more are likely deficient, magnesium supplementation is recommended when taking vitamin D supplements. This is because magnesium helps to activate vitamin D, as the enzymes that metabolize vitamin D in your liver and kidneys require magnesium.
What GrassrootsHealth observed in testing and analyzing nutrient intakes from over 15,000 patients is that about half of those taking vitamin D supplements were unable to normalize their vitamin D levels until they started to take supplemental magnesium.
They also found that those who do not take supplemental magnesium need, on average, 146% more vitamin D per day to achieve a healthy blood level of 40 ng/ml (100 nmol/L), compared to those who take at least 400 mg of magnesium along with their vitamin D supplement.
Omega-3 Fats Are Crucial to Your Well-Being
Meanwhile, recent research suggests high doses (4 grams) of the omega-3 fats EPA and DHA may help improve healing after a heart attack. Other benefits of omega-3 fats include prevention of lupus and Parkinson’s disease, decreased anxiety, healthier and stronger bones, as well as fighting fats in the body.
However, you can’t tell by looking in a mirror if you are deficient in vitamin D, magnesium or omega-3s. The only real way to know if you are deficient in these nutrients is to get tested.
