Optimal Nutritional Status For A Well Functioning Immune System Is An Important Factor To Protect Against Viral Infections

This research review examined how nutrition affects our immune system's ability to protect us from viral infections. The scientists analyzed numerous studies to understand which nutrients are most important for maintaining strong immune defenses against respiratory infections like influenza and COVID-19, which cause millions of deaths worldwide each year.

The researchers found that several specific nutrients play crucial roles in supporting immune function: vitamins A, B6, B12, C, D, E, and folate; minerals like zinc, iron, selenium, magnesium, and copper; and omega-3 fatty acids (EPA and DHA found in fish oil). These nutrients work together in complementary ways to help your immune system recognize threats, mount appropriate responses, and recover from infections. Unfortunately, many people don't get adequate amounts of these nutrients from their diets alone, which can weaken their natural defenses.

The study concluded that taking supplements containing these immune-supporting nutrients is a safe, effective, and affordable way to optimize immune function. For certain nutrients like vitamins C and D, the researchers found that taking amounts higher than the standard recommended daily allowances—but still within safe limits—may provide additional protection. This is particularly relevant for metabolic health because chronic inflammation and poor immune function often go hand-in-hand with metabolic disorders.

In clinical practice, this research supports a comprehensive approach to health that includes nutritional optimization alongside other preventive measures. At VALIA Health, we can assess your individual nutrient status and develop personalized supplementation strategies to support both your immune system and overall metabolic health, helping you build resilience against infections while promoting longevity.
