The immune system naturally declines after age 20, making individuals more susceptible to infections, studies show.
While chronic illnesses such as diabetes and hypertension are widely known to weaken the immune system, research indicates that even healthy individuals experience a decrease in T cells, a type of white blood cell essential in fighting infections. Scientists attribute this decline to the body’s reduced ability to release T cells after adolescence.
Lifestyle factors, including lack of sleep, poor diet, and chronic stress, may further compromise immune function. Some studies suggest that incorporating Vitamin C and Zinc into daily routines can help support immune responses.
Vitamin C acts as an antioxidant, protecting cells from damage, while Zinc plays a crucial role in immune cell function. However, experts note that Zinc can degrade Ascorbic Acid (Vitamin C), potentially reducing its efficacy before absorption.
According to Unilab, maintaining a balanced intake of Vitamin C and Zinc through diet and supplementation may contribute to better immune defense. The company offers ImmunPro, a Vitamin C and Zinc supplement developed with ZincPlus® Technology, which helps stabilize the combination for better absorption.
R&D organization Synapse also states that proper nutrition, regular exercise, and adequate sleep are key to maintaining overall health.
Health experts emphasize that regardless of age or medical condition, strengthening the immune system is essential to reducing the risk of infections.
