Synopsis

Rating (out of 5): 4

Vitamin C, also known as ascorbic acid, has substantial scientific evidence supporting its role in maintaining capillary health. Vitamin C is essential for the biosynthesis of collagen, a key structural protein in blood vessels, including capillaries. Collagen provides strength and integrity to the vascular wall, helping prevent capillary fragility and rupture. Deficiency in vitamin C leads to scurvy, a condition marked by weakened blood vessels and capillary bleeding, underscoring its importance in capillary integrity.

Multiple studies have demonstrated that adequate vitamin C intake improves endothelial function and reduces capillary permeability. For instance, clinical evidence shows that vitamin C supplementation can decrease the risk of bleeding and bruising associated with capillary fragility, especially in individuals with marginal vitamin C status. Furthermore, vitamin C acts as a potent antioxidant, protecting the vascular endothelium from oxidative stress and inflammation, both of which can compromise capillary function.

In summary, vitamin C’s use in supporting capillary health is well-founded in both basic physiological research and clinical observation, and its role is recognized in both medical and nutritional guidance.
