A healthy immune system is necessary for good health and to fight infections. Of course, a well-rounded diet with fruits and vegetables, daily exercise and good sleep contribute greatly to immunity, but natural supplements can help. These supplements assist in fortifying your body with everything from vitamins and minerals to potent plant-derived substances. Here are a few of the top natural immune modulators you can look for.

Nicotinamide Riboside, the Cellular Fuel

A prior one study found nicotinamide riboside (a form of vitamin B3) to boost health and immunity at a cellular level. Nicotinamide serves as a precursor to the coenzyme nicotinamide adenine dinucleotide (NAD+) which is critical to energy metabolism and DNA repair. Sufficient levels of NAD+ play an important role in immune cell functions, thus enhancing protection against pathogens. Nicotinamide riboside supplementation can assist the body more effectively fight infections and the body has to repair itself.

Vitamin C: The Old Standby of Immune Health

Perhaps the best-known immune-boosting nutrient is vitamin C. It is a strong antioxidant that protects immune cells from oxidative stress and increases white blood cell production, which is responsible for an immune response to pathogens. While fruits are the best source, such as bell-peppers, strawberries and citrus are all high in vitamin- C, but due to the flu season, you must fulfill your daily needs with supplements to meet up.

Nicotinamide Riboside and Immunity in Human Aging

While poor immunity is a natural consequence of aging, it nevertheless increases the risk of infections and chronic diseases. Studies indicate that increasing NAD+ levels using nicotinamide riboside supplementation support immune cell function and may help combat age-associated immune decline. Nicotinamide riboside contributes to the maintenance of a robust and responsive immune system in older adults by restoring mitochondrial function and reducing oxidative stress.

Zinc: A Key Player in Immune Function

Zinc is an essential mineral with many roles in the body, especially for immunity. Its an important hormone for the development and differentiation of t-cells which are an integral part of immune response. It also has anti-inflammatory, antioxidant properties that play a role in reducing the hyperactivity of the immune system. Zinc is provided by foods such as nuts, seeds, and legumes, yet there are circumstances under which supplementation is especially useful, such as with those that are deficient or have higher demands by the immune system.

Probiotics: Maintaining Gut Health to Fortify Immunity

Since most of the immune system is guts, gut health is crucial for immunity. Probiotics, or live microorganisms, are designed to balance the microbiome of the gut to support our immune system function. Yogurt, kimchi, and sauerkraut are examples of fermented foods that contain probiotics, but supplements can really bulk up this immune barrier with the added benefit of putting only the most beneficial doses of bacteria in a convenient and consistent format.

Elderberry: A More Natural Antiviral Treatment

For centuries, elderberry has been used to relieve cold and flu symptoms; Nutritionally, elderberry extract contains high levels of flavonoids and antioxidants, potentially combating respiratory infections with its antiviral properties that may lessen severity and duration of symptoms. Elderberry is another supplement that appears to have the potential to bolster an immune response and reduce inflammation, so it can be a worthwhile addition to any immune-strengthening protocol.

Vitamin D: The Vitamin Of Sun

Vitamin D — one of the critical immune boosters; we are often deficient in and most especially in the cold months. It regulates immunity and supports the production of peptides that help fight infections. Although getting some sun exposure is the ideal natural vitamin D source, vitamin D supplements can ensure sufficient levels throughout the calendar year (5).

The Powers of Adaptogenic Herbs: Ashwagandha & Reishi Mushroom

Adaptogenic herbs such as ashwagandha and reishi mushroom balance the immune system and increase stress resilience. This ability becomes compromised due to chronic stress that suppresses immune function allowing an individual more readily to fall ill. Reishi mushroom is an immunomodulator that supports white blood cell activity as well as overall immune defense; and ashwagandha provides adrenal support.

Allicin, present in garlic, possesses strong antimicrobial and antivirus properties and makes boosts the immune system. Garlic also has strong immune boosting properties, and you should consider consuming garlic more often for a lower risk of infections. Is a great food for a diet focused on immunity, raw, in food or in the form of supplements.

Track Your Progress Then You Can Adjust

Your supplement plan should change as your body— and life — changes. Stop periodically to see how you feel and if you believe the supplements have had a positive impact on your health and well-being. Talk to a health professional about how to make adjustments if you are not seeing the benefits or side effects.

Tests such as blood tests and nutritional assessments reveal deficiencies and inform a tailored supplement regimen to your body. The aim is to establish an efficient and habitual practice that improves you in all possible facets without the dependence on filler supplements.

Conclusion

Adding some natural supplements in your daily life can do a lot to strengthen your immune system in fighting off pathogens to keep you fit and healthy. Cellular-level immune-supporting powerhouses including nicotinamide riboside, vitamin C, zinc, probiotics, elderberry, and more. Supplements can be a great tool for support, but they are no substitute for a healthy lifestyle. As always, if you are thinking of adding any new supplement to your regimen, check with your physician to see if it is appropriate for your individual health concerns.
