In the meantime, general healthy-living strategies make sense since they likely help immune function and they come with other proven health benefits.

Beyond The Common Cold

Although supplements can’t ward off the common cold, vitamin C is still important to your health. It serves essential roles in the human body and supports normal immune function, according to a 2017 report in the journal Nutrients.

Vitamin C acts as an antioxidant, meaning it neutralizes free radicals generated by the body’s normal metabolism and by exposure to environmental stressors, including ultraviolet radiation and air pollution. Free radicals are charged particles that can damage cells, tissues and genetic material if left unchecked, and thus trigger harmful inflammation.

Besides stopping free radicals, vitamin C helps to activate several key enzymes in the body, which go on to synthesize hormones and build collagen, a tough protein found in skin and connective tissues, according to the 2017 report. These hormones help control the response of the cardiovascular system to severe infections, while collagen fortifies the skin against injury.

Vitamin C may also bolster the fatty membranes in skin and connective tissue, thus protecting organs like the lungs from pathogens, according to cell culture and preclinical studies. When bugs do infiltrate the body, vitamin C helps direct immune cells called neutrophils to the site of infection and defends these cells against free radicals, the 2017 report noted.
