CAS PubMed Google Scholar Powell, R. However, many professionals within the health and science community argue that supplementing with Vitamin D is generally safe and could possibly help protect individuals from the virus Vitamin D is essential for immune function.
Healthy levels of this vitamin may help lower your risk for respiratory infections. This is because zinc is essential for immune system function. Zinc is needed for immune cell development and communication and plays an important role in inflammatory response.
Zinc also specifically protects tissue barriers in the body and help prevent foreign pathogens from entering Zinc deficiency affects around 2 billion people worldwide and is very common in older adults. Zinc deficiency is relatively rare in North America and in developed countries 17 , Nevertheless, many individuals in the United States have marginal zinc deficiency related to intake or absorption.
Older individuals are generally at an increased risk Numerous studies reveal that zinc supplements may protect against respiratory tract infections like the common cold 19 , In a study in 64 hospitalized children with acute lower respiratory tract infections ALRIs , taking 30 mg of zinc per day decreased the total duration of infection and the duration of the hospital stay by an average of 2 days, compared with a placebo group Supplemental zinc may also help reduce the duration of the common cold Additionally, zinc demonstrates antiviral activity 23 , Taking zinc long term is typically safe for healthy adults, as long as the daily dose is under the set upper limit of 40 mg of elemental zinc Supplementing with zinc may help protect against respiratory tract infections and reduce the duration of these infections.
Vitamin C is perhaps the most popular supplement taken to protect against infection due to its important role in immune health. This vitamin supports the function of various immune cells and enhances their ability to protect against infection.
Vitamin C also functions as a powerful antioxidant, protecting against damage induced by oxidative stress, which occurs with the accumulation of reactive molecules known as free radicals.
Oxidative stress can negatively affect immune health and is linked to numerous diseases Supplementing with vitamin C has been shown to reduce the duration and severity of upper respiratory tract infections, including the common cold Additionally, high-dose intravenous vitamin C treatment has been shown to significantly improve symptoms in people with severe infections, including sepsis and acute respiratory distress syndrome ARDS resulting from viral infections Still, other studies have suggested that the role of vitamin C in this setting is still under investigation 32 , The upper limit for vitamin C is 2, mg.
Supplemental daily doses are typically between and 1, mg Vitamin C is vital for immune health. Supplementing with this nutrient may help reduce the duration and severity of upper respiratory tract infections, including the common cold.
Black elderberry Sambucus nigra , which has long been used to treat infections, is being researched for its effects on immune health. In test-tube studies, elderberry extract demonstrates potent antibacterial and antiviral potential against bacterial pathogens responsible for upper respiratory tract infections and strains of the influenza virus 35 , A review of 4 randomized control studies in people found that elderberry supplements significantly reduced upper respiratory symptoms caused by viral infections However, this study is outdated and was sponsored by the elderberry syrup manufacturer, which may have skewed results Though it has been suggested that elderberry can help relieve symptoms of certain infections and the influenza virus, we also must be aware of the risks.
Some report that elderberries can lead to the production of excess cytokines, which could potentially damage healthy cells For that reason, some researchers recommend elderberry supplements only be used in the early course of COVID It should be noted no published research studies have evaluated the use of elderberry for COVID These recommendations are based on previous research done on elderberries.
A systemic review of elderberry 43 concluded:. Taking elderberry supplements may help reduce upper respiratory symptoms caused by viral infections and help alleviate flu symptoms.
However, elderberry also has risks. More research is needed. Medicinal mushrooms have been used since ancient times to prevent and treat infection and disease. Many types of medicinal mushrooms have been studied for their immune-boosting potential.
Over recognized species of medicinal mushrooms are known to have immune-enhancing properties In a Cochrane review of 12 randomized controlled trials, probiotics cut the number of respiratory infections nearly in half. You can find probiotics in kefir, yogurt and fermented foods like miso and sauerkraut look for unpasteurized products sold in the refrigerated sections of your supermarket.
But supplements are probably the best way to get the amount needed to fight infections. Many probiotics are heat-sensitive and should be refrigerated, both at home and in the store where you buy them. Look for brands that have been independently tested by a third party for purity and potency.
Unlike drug manufacturers, the Food and Drug Administration FDA does not require supplement makers to prove their product is safe or effective before selling them. For tips on choosing safe, quality supplements, click here.
Again, always talk to your doctor before starting a new supplement. Your doctor can help you choose the right product and dose as well as help you avoid any potential medication side effects. Get involved with the arthritis community.

Intrinsic antiviral immunity refers to a form of innate immunity that directly restricts viral replication and assembly, thereby rendering a cell nonpermissive to a specific class or species of viruses. Intrinsic immunity is conferred by restriction factors that are mostly preexistent in certain cell types, although these factors can be further induced by viral infection. Intrinsic virus-restriction factors recognize specific viral components, but unlike other pattern-recognition receptors that inhibit viral infection indirectly by inducing interferons and other antiviral molecules, intrinsic antiviral factors block viral replication immediately and directly.
