Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Vitamin C, including its buffered form calcium ascorbate, has scientific support for its role in supporting the health and function of mucus membranes. Mucus membranes line the respiratory, gastrointestinal, and genitourinary tracts and serve as a barrier against pathogens. Vitamin C is essential for the synthesis of collagen, a protein that provides structural support to epithelial tissues, including those that make up mucus membranes. Deficiency in vitamin C can lead to weakened mucus membranes, making them more susceptible to damage and infection, as seen in the symptoms of scurvy, which include gum bleeding and oral mucosal breakdown.

Several studies have indicated that adequate vitamin C intake supports the maintenance and repair of epithelial barriers. Vitamin C’s antioxidant properties also help protect mucus membranes from oxidative damage caused by environmental toxins and pathogens. Some clinical research has shown that vitamin C supplementation may reduce the severity and duration of respiratory infections, likely due to its role in maintaining epithelial integrity and immune function.

However, while there is biological plausibility and indirect clinical evidence, direct high-quality trials specifically measuring the effect of vitamin C (including calcium ascorbate) on mucus membrane health in healthy, non-deficient individuals are limited. The evidence is stronger in cases of deficiency or increased demand (e.g., during infections or inflammation).
