Which nutrients are known to improve immune system function?

The nutrients that enhance immune system function encompass a variety of components that play specific roles in supporting and optimizing immune response. Glutamine is an amino acid that serves as a crucial fuel source for immune cells, particularly during periods of stress or infection. Protein, in general, is essential for the growth and repair of tissues and aids in the production of antibodies and immune cells, vital for defending against pathogens.

Vitamin C is well-documented for its immune-boosting properties, as it is involved in various cellular functions of both the innate and adaptive immune system. It acts as an antioxidant and can enhance the production of white blood cells, key players in immune defense. Zinc also plays a critical role in immune function; it is necessary for the development and function of immune cells and has been shown to reduce the duration of colds when supplemented. Echinacea, an herbal supplement, is commonly used to prevent or treat colds and other respiratory infections due to its purported immune-stimulating properties.

When these nutrients are combined, they work synergistically to boost the immune system, making this selection the most comprehensive and beneficial in terms of supporting immune health.
