Discover how supplements like probiotics, vitamins, and beta-glucan can enhance your immune system and reduce illness severity for better health.
The immune system is a complex network that protects the body from harmful invaders, relying on both innate and adaptive immunity.
Innate immunity is the body’s first line of defense, acting quickly but nonspecifically through barriers like the skin and immune cells, such as macrophages and natural killer cells.
Adaptive immunity, on the other hand, responds more slowly but creates long-term protection through specialized T and B cells that remember past threats.
Factors like nutrition, age, activity level, and overall health influence the strength of these immune responses.
Several supplements have been shown to support immune function, reduce the number of infections, or reduce the length and severity of illness.
These supplements include probiotics, vitamins C and D, zinc, and elderberry extract. Beta-glucan, a yeast-derived polysaccharide, when taken prophylactically, can prime the immune system and help reduce the risk of infection.
