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

Vitamin C (ascorbic acid) is scientifically validated as important for supporting the health of capillaries and the broader vascular system. Its role centers on collagen synthesis, a critical structural protein that maintains the integrity and elasticity of blood vessel walls, including capillaries. Deficiency in vitamin C leads to weakened collagen structures, resulting in fragile capillaries that are prone to rupture, manifesting clinically as easy bruising, petechiae, and bleeding gums—a classic sign of scurvy. Numerous studies have demonstrated that adequate vitamin C intake helps maintain capillary strength and reduces capillary fragility. For example, controlled studies have shown that supplementation with vitamin C can decrease capillary bleeding time and improve vascular health. Furthermore, vitamin C’s antioxidant properties protect endothelial cells lining the capillaries from oxidative damage, which could otherwise compromise capillary function. Historical evidence also supports its use: the connection between vitamin C and capillary health was first established in the 18th century during investigations into scurvy among sailors. In summary, the use of vitamin C to support capillary health is underpinned by robust scientific evidence relating to its biochemical function and clinical studies, warranting a relatively high rating for evidence.
