Vitamin D & Immune Function

How to improve your immune system with vitamins amid COVID-19 pandemic

Vitamin D is slightly different to other vitamins because it is a hormone made by your body in a chemical reaction which occurs when your skin is exposed to sunlight.

For this reason, it is often referred to as the sunshine vitamin. However, it is only created by your body if youre exposed to adequate levels of sunlight. Supplementing with vitamin D during the months with less sun could help you boost your immune system.

Vitamin D and your immune system play crucial roles in many functions within your body. Your immune system is your bodys first line of defense against infection and disease so its important to ensure that youre not experiencing low levels of nutrients like vitamin D. Low levels could lead to deficiencies which can cause detrimental side effects.

Vitamin D plays a role in the proper functioning of t cells, b cells and dendritic cells which are all key to immune function and protecting your body from disease.

In addition, Vitamin D helps your body to effectively absorb calcium which helps your body to maintain healthy bones.

Effects Of Antioxidant Vitamins On Immunity

It has been known for more than 30 years that some vitamins with antioxidant properties, including vitamin A, vitamin B6 , vitamin C and particularly vitamin E, have protective effects on animal models of atherosclerosis and ischaemia-reperfusion injury . Vitamin E collectively refers to eight related compounds , of which -tocopherol has the greatest bioavailability and is the best characterized. Vitamin E decreases the release of reactive oxygen species by monocytes and the expression of CD11b and very late antigen 4 , thereby decreasing monocyte adhesion to the endothelium. Vitamin E also blocks the release of pro-inflammatory cytokines, including IL-1, IL-6, TNF and the chemokine IL-8, by monocytes and macrophages,. Moreover, vitamin E prevents the upregulation of the adhesion molecules vascular cell-adhesion molecule 1 and intercellular adhesion molecule 1 on the endothelium induced by oxidized low-density lipo protein and IL-1, as well as the upregulation of E-selectin and some chemokines. Reactive oxygen species activate the nuclear factor-B pathway, which initiates many pro-inflammatory events. Therefore, the therapeutic antioxidant effect of these vitamins could be explained, at least in part, by their capacity to decrease NF-B activation.

What Can You Do To Boost Your Immune System

The idea of boosting your immunity is enticing, but the ability to do so has proved elusive for several reasons. The immune system is precisely that a system, not a single entity. To function well, it requires balance and harmony. There is still much that researchers don’t know about the intricacies and interconnectedness of the immune response. For now, there are no scientifically proven direct links between lifestyle and enhanced immune function.

But that doesn’t mean the effects of lifestyle on the immune system aren’t intriguing and shouldn’t be studied. Researchers are exploring the effects of diet, exercise, age, psychological stress, and other factors on the immune response, both in animals and in humans. In the meantime, general healthy-living strategies make sense since they likely help immune function and they come with other proven health benefits.

Immunity in action. A healthy immune system can defeat invading pathogens as shown above, where two bacteria that cause gonorrhea are no match for the large phagocyte, called a neutrophil, that engulfs and kills them .

Le Lien Qui Existe Entre Votre Sant Intestinale Et Votre Systme Immunitaire

La santé de votre tractus gastro-intestinal est directement liée à la santé et au fonctionnement de votre système immunitaire. Le microbiome, lui, est un ensemble de micro-organismes que lon trouve principalement dans lintestin. À titre dexemple, vos bactéries intestinales jouent de nombreux rôles importants dans votre organisme. En effet, elles régulent votre métabolisme, votre humeur, vos fonctions cognitives, votre appétit, votre digestion et votre immunité1. Tout comme pour le microbiome, qui vit en majorité dans lintestin, environ 70 % du système immunitaire sy trouve aussi1.Et cest parfait ainsi puisque cest par là même où de nombreux agents pathogènes, y compris les virus, les parasites et les bactéries nocives, pénètrent dans lorganisme.

Une relation symbiotique

Le système immunitaire et lintestin entretiennent une relation symbiotique.Cela signifie que le système immunitaire et le microbiome humains bénéficient tous deux de cette connexion.Les bonnes bactéries qui font partie du microbiome entraînent les cellules immunitaires à reconnaître les agents pathogènes, tandis que lintestin signale au système immunitaire de générer les réponses immunitaires appropriées2. Le système immunitaire, quant à lui, contribue à maintenir un microbiome diversifié et en santé2. Cette délicate communication bidirectionnelle entre votre intestin et vos cellules immunitaires peut être favorisée par des choix de vie judicieux et des nutriments spécifiques.

Sunlight Exposure And Vitamin D

Vitamin D is associated with the sun for a reason — your body can produce its own vitamin D when you expose your skin to the sun for a period of time. About 15 minutes of sun exposure per day is what many experts say is sufficient to make vitamin D. This means you want to have a good amount of skin uncovered by clothing or sunscreen since those things inhibit Vitamin D production, according to Tolentino.

How much sun you should get is also a bit complicated. “UVB radiation from the sun triggers vitamin D synthesis in our bodies, but there are a lot of factors to consider here,” says Tolentino

She continues, “Where you live , sunscreen usage and coverage and the amount of melanin in your skin can all impact vitamin D absorption. That makes it really difficult to provide generalized guidelines for the appropriate amount of sun exposure. What may be a sufficient or healthy amount of time in the sun with no sun protection for one person might not be advisable for another person.”

You body can easily absorb a liquid vitamin D or tincture since you can take the drops under your tongue.

Whats The Best Supplement

One more thing to note: The safety and effectiveness of vitamins are not regulated by the Food and Drug Administration, so before stocking up at the store, you should look for at least one of two endorsements, says Dr. Chan:

  • United States Pharmacopeia : This non-profit organization independently tests and reports on supplements. They analyze the product and then certify the consistency of the product, according to the label, says Dr. Chan. If you look for a product with USP certification, at least you have more of a guarantee that youre getting what you intend to purchase.
  • Consumer Reports: The product-testing publication also periodically does its own independent testing of supplements and reports the results.
  • Dosage differs for each, so check with your physician or pharmacistand always mention any supplements you take when filling a prescription.

    Increase Immunity The Healthy Way

    Many products on store shelves claim to boost or support immunity. But the concept of boosting immunity actually makes little sense scientifically. In fact, boosting the number of cells in your body immune cells or others is not necessarily a good thing. For example, athletes who engage in “blood doping” pumping blood into their systems to boost their number of blood cells and enhance their performance run the risk of strokes.

    Attempting to boost the cells of your immune system is especially complicated because there are so many different kinds of cells in the immune system that respond to so many different microbes in so many ways. Which cells should you boost, and to what number? So far, scientists do not know the answer. What is known is that the body is continually generating immune cells. Certainly, it produces many more lymphocytes than it can possibly use. The extra cells remove themselves through a natural process of cell death called apoptosis some before they see any action, some after the battle is won. No one knows how many cells or what the best mix of cells the immune system needs to function at its optimum level.

    Vitamins to boost immune system from COVID-19

    During the winter months, you’ve likely seen ads for products that claim to give your immune system a boost to help you ward off colds and the flu. But can something in a bottle, whether a vitamin formulation or probiotic, really rev up your immune system to help you stay healthy?

    “Unfortunately, the reality is that those kinds of products aren’t really offering you any benefit,” says Michael Starnbach, a professor of microbiology at Harvard Medical School. “There’s no evidence that they help in fighting disease.”

    To understand why, you need to know a little about how the immune system works. The very idea of boosting the immune system is flawed.

    “The immune system is very finely tuned,” says Starnbach. There is a balance between an immune system that is effective at limiting the ability of bacteria, viruses, and parasites to cause infection, and a hyperactive immune system that can cause such problems as allergies, diabetes, and other types of autoinflammatory and autoimmune disorders.

    “If there were a wholesale boost to the immune system, it could trigger autoimmunity and other problems,” he says.

    Vitamin Metabolites And Lymphocyte Homing

    Roles of retinoic acid and 1,252VD3 in tissue-specific lymphocyte homing

    Although vitamin A deficiency decreases the number of T and B cells in the small bowel lamina propria,,,, it does not affect lymphocyte migration to the colon. Analogously, GALT-resident DCs imprint T and B cells with homing capacity for the small bowel, but they do not induce colon-homing T cells. Therefore, retinoic acid is neither necessary nor sufficient to imprint colon-homing lymphocytes. The molecular signals that are responsible for lymphocyte homing to the colon and the reasons why T-cell migration to this compartment is controlled differently from homing to the small bowel are still to be determined.

    Regarding the migration of ASCs, it has been proposed that CCR10 might have a role in the homing of IgA+ ASCs to the colon, mammary glands and probably to other mucosal compartments . However, it is currently unclear how CCR10 expression is induced by ASCs. Recent reports indicate that IgA+ ASCs might acquire CCR10 expression in colonic patches or in iliac lymph nodes following rectal immunization and that the expression of this receptor can also be induced by 1,252VD3 in human ASCs. However, 1,252VD3 does not induce CCR10 expression in murine ASCs in vitro and VDR-deficient mice have normal numbers of CCR10+ IgA+ ASCs, which indicates that 1,252VD3 might not be necessary for the induction of CCR10 expression by B cells in vivo, at least in mice.

    The Role Of Nutrition In Immune Health

    Research shows when the body has optimal nutrition, it initiates an effective response against pathogens and is more successful in combating any underlying chronic inflammationChilds C, Calder P, Miles E. Diet and Immune Function. Nutrients. 2019 11:1933. .

    The gut is home to one of the largest reservoirs of our immune system, and poor nutrition quite simply increases the risk of infection and transforms that once-protective gut barrier into the equivalent of Walmart on Black Friday, says Dr. Fenster.

    This internal chaos created from eating less-than-nutritious foods can also become a bit of a vicious cycle. When the immune system is activated in the face of potential threats , theres a greater demand for energy, and a proper supply of nutrients is required to fight an active infection. Without those nutrients, your body doesnt have the stores from which to pull that could help you get well sooner.

    Adequate and appropriate nutrition is required for the cells of the body to function optimally, and this includes cellular immune health, says David Friedman, a naturopathic doctor, clinical nutritionist and board-certified alternative medical practitioner based in North Carolina. When the body is exposed to disease-causing germs, the best defense is a healthful diet and nutrition.

    Long story short, if you want to stay healthy this holiday season, pay attention to what makes it to your plate.
