The immune system is your body’s primary mechanism of defense, responsible for protecting you from potentially harmful invaders, including viruses. Certain lifestyle interventions can support your immune function, including:
Maintaining a balanced healthy diet, which focuses on whole, unprocessed foods high in antioxidants
Additionally, the following evidence-based dietary supplement ingredients may provide immune support.
The following are some of the top ingredients recommended on Fullscript for immune support.
Vitamin C, found in dietary sources such as citrus, broccoli, and kiwi, plays an important role in immune function by supporting both innate and adaptive immune systems. Vitamin C deficiency may result in reduced immunity and a higher risk of infections. Supplementing with vitamin C has been shown to be effective in treating respiratory and systemic infections.
Vitamin D is a fat-soluble vitamin required in mineral metabolism, bone health, and immune function. Research has demonstrated that individuals with vitamin D deficiency are at increased risk of contracting upper respiratory tract infections, such as the common cold, compared to individuals with normal vitamin D status. Further research suggests that vitamin D supplementation may support immune tolerance in autoimmune conditions and enhance the anti-microbial effect of certain immune cells.
The mineral zinc is commonly recommended to protect against the common cold. Zinc can be obtained in the diet from seafood, animal proteins, pumpkin seeds, yogurt, and cashews, as well as from dietary supplements. Research has found that zinc lozenges, when taken at the onset of a cold for a minimum of one to two weeks, may help reduce the symptoms and duration of colds in children and adults.
Probiotics are beneficial live microorganisms that may support immune health by modulating immune responses and inhibiting the growth of pathogens in the gastrointestinal tract. Probiotics may be obtained from fermented foods, including yogurt, kefir, sauerkraut, unpasteurized pickled vegetables, and kombucha. Probiotic supplements may help protect healthy individuals against respiratory infections, reduce the severity of colds.
