Probiotics: Probiotics are live microorganisms that provide health benefits when consumed in adequate amounts. They have been shown to modulate the immune system and improve gut health, which is essential for overall immune function (La Fata et al., 2020). Studies have identified the benefits of probiotic supplementation in reducing the incidence and severity of respiratory infections, especially in children (La Fata et al., 2020; Wang et al., 2016).
Conclusion: Nutritional supplements can provide additional support to the immune system, especially when the body is under stress or lacks proper nutrition. Vitamin C, zinc, and probiotics have been shown to have immune-boosting properties and can help reduce the severity and duration of infections. However, it is important to note that these supplements should not replace a balanced diet and should only be used under the guidance of a healthcare professional.
