Prevents gut dysbiosis and intestinal inflammation Contributes to reduction in systemic inflammatory response Improves outcomes in upper respiratory and lower respiratory infection Modulates antiviral activity via stimulation of native immunity in the gut.

Downregulates ACE2 receptors, altering gut microbiota Upregulates pro-inflammatory chemokines and cytokines, including fecal calprotectin and serum interleukin-6 Microbial dysbiosis with decreased Lactobacillus and Bifidobacterium species in patients with COVID Western diet is pro-inflammatory by impairing adaptive immunity and host defense against viral infection Mediterranean diet is rich in antioxidant functional foods, which help to support the systemic immune response Low protein intake contributes to increased infection risk, and higher protein intake is associated with lesser inflammatory state Greater dietary fiber intake is associated with reduced risk of death from respiratory or infectious causes Adiponectin, an anti-inflammatory chemokine, is higher in those consuming and adherent to Mediterranean diet.

Worsened outcomes in obese patients COVID quarantine measures worsen food intake quality and leads to weight gain in general population Malnutrition is highly prevalent in elderly patients with COVID and patients should be screened. Reduces pro-inflammatory cytokines Enhances antiviral immune response Omega-3 FAs attenuate inflammatory response in ARDS mouse and human models, though meta-analysis of human studies with nonsignificant effect.

Potential risk of increased bleeding Association with atrial arrhythmias Oxidation of Omega-3 FAs by reactive oxygen species may increase oxidative stress; co-treatment with antioxidants may mitigate this effect.

Antioxidant and enzyme cofactor May limit pro-oxidant effects when given in conjunction with other supplements Pro-oxidant properties at higher doses when given IV which may inhibit hyperactivation of over-stimulated myeloid and lymphoid cells. Oral: abdominal pain, diarrhea IV high-dose : hemolytic anemia in patients with G6PD-deficiency; glucose. Vitamin C levels are depleted during the acute stage of infection due to increased metabolic demands Many patients with severe COVID have elevated levels of the mediators interleukin-6 and endothelin-1 which may explain the propensity of COVID19 pneumonia for elderly, male, obese, hypertensive patients, as well as of persons of color and smokers.

Supports both innate and adaptive immune mechanisms Inhibition of T cell proliferation, production of cytokines, antibody synthesis by B lymphocytes Stimulate surfactant synthesis in alveolar cells. No significant adverse effects reported.

Mild gastrointestinal symptoms. Antioxidant involved in metabolic regulation and promoting cellular homeostasis. So the next step is to conduct randomized clinical trials, in which volunteers are assigned by lot to take either the supplement or an identical-looking placebo "dummy pill" while researchers track their health.

In the best studies, neither the volunteers nor the researchers know who is getting the real thing until the code is broken at the end of the trial. Everyone wants to know if supplements can help.

It's a good question. Here's where we stand today — but you should keep an eye out for new results, since recommendations will change as scientific studies trickle in.

Unfortunately, in most cases, the studies have failed to confirm our hopes, though there are exceptions. Many people take supplements in the belief that they will preserve health or ward off illness; many others use supplements in an attempt to treat specific conditions that have already developed.

We'll have a look at popular supplements in both categories, starting with preventive supplements used principally by healthy people.

Vitamin D. To get vitamin D the old-fashioned way, by producing it in the skin, we need lots of sunshine. But as work has shifted from the farm to the office and as we've learned to use sunscreens to reduce the risk of skin cancer and wrinkles, many people lack sufficient amounts of the "sunshine vitamin. Vitamin D is needed to absorb calcium from the intestines; that's why vitamin D is so important for healthy bones.

Current guidelines call for IU international units a day below age 71 and IU a day thereafter. But many experts recommend to 1, IU a day for most adults; daily doses up to 4, IU are considered safe, but more can be toxic. It's very hard to get the vitamin D you need from your diet; oily fish and fortified dairy products are the only important sources. So supplements do make good sense for most adults.

The form known as vitamin D 3 is usually recommended, but D 2 is also effective; for best results, take your vitamin D along with a meal that has some fat. If you want to be sure you need this supplement, ask for a blood test; levels of at least 30 nanograms per milliliter are considered best. Vitamin E, vitamin A, beta carotene, and vitamin C were the favorites of the s and early '90s. But many careful randomized clinical trials have not shown any benefit against heart disease, cancer, or other illnesses.

And that's not the worst of it. In fact, even moderately high doses of vitamin A increase the risk of hip fractures, and high levels of vitamin A have been linked to an increased risk of prostate cancer; beta carotene increases lung cancer risk in smokers; and vitamin E increases the risk of prostate cancer and has been linked to an increase in respiratory infections, heart failure, and the overall death rate.

Do not take antioxidant supplements. One exception: people with moderate or advanced age-related macular degeneration AMD benefit from special antioxidant supplements that also contain zinc. Unfortunately, though, this preparation does nothing to prevent AMD in people who have healthy eyes.

Vitamin B 12 is found only in animal-based foods, so strict vegetarians may need supplements.
