Synopsis

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

Vitamin C, including its buffered form calcium ascorbate, is scientifically validated to support capillary health. Its primary function is as a cofactor for enzymes involved in the biosynthesis of collagen, a structural protein essential for the integrity of blood vessel walls, including capillaries. Deficiency in vitamin C leads to scurvy, a condition characterized by weakened capillary walls resulting in bleeding and easy bruising. Numerous studies have demonstrated that adequate vitamin C intake helps maintain the strength and function of capillaries by facilitating proper collagen formation and acting as an antioxidant, protecting vascular tissues from oxidative stress. While severe vitamin C deficiency is rare in developed countries, suboptimal intake may be linked to increased capillary fragility. Clinical trials and observational studies support the role of vitamin C in reducing capillary bleeding and improving vascular function, especially in populations at risk for deficiency. Therefore, the use of vitamin C (including calcium ascorbate) for capillary health is supported by robust scientific evidence, particularly regarding its role in collagen synthesis and maintaining capillary integrity.
