Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Vitamin C (ascorbic acid) has a well-established scientific basis for supporting capillary health. This water-soluble vitamin is essential for the synthesis of collagen, the principal structural protein found in the walls of blood vessels, including capillaries. Collagen provides strength and elasticity to capillary walls, helping to prevent them from becoming fragile or permeable. Numerous studies, starting from the early 20th century, have demonstrated that vitamin C deficiency leads to scurvy—a disease characterized by weakened connective tissue, bleeding gums, and capillary fragility resulting in easy bruising and hemorrhages. Supplementation with vitamin C rapidly reverses these symptoms, underscoring its critical role in maintaining capillary integrity. Beyond deficiency states, some research suggests that vitamin C supplementation may help reduce capillary permeability and bruising in individuals prone to these issues, although evidence for benefit in people with adequate vitamin C intake is less robust. The European Food Safety Authority (EFSA) and other regulatory bodies recognize vitamin C's contribution to normal collagen formation for the normal function of blood vessels. In summary, the use of vitamin C to support capillary health is strongly supported by scientific evidence related to its physiological role in collagen synthesis and the prevention of capillary-related symptoms of deficiency.
