Synopsis

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

Vitamin K (Phylloquinone) is scientifically validated as crucial for normal blood coagulation, and its role in supporting the capillaries relates primarily to its involvement in the synthesis of clotting factors and proteins that help maintain vascular integrity. Specifically, vitamin K is required for the gamma-carboxylation of certain glutamate residues in proteins to form gamma-carboxyglutamate (Gla) residues, a process essential for the function of clotting factors II, VII, IX, and X, as well as proteins C and S. Deficiency in vitamin K can result in increased bleeding tendency, easy bruising, and, in severe cases, hemorrhagic disease, all of which are related to capillary and vascular fragility.

Clinical and biochemical evidence supports vitamin K’s role in preventing capillary bleeding and bruising. For example, studies have demonstrated that vitamin K supplementation corrects prolonged prothrombin time and prevents bleeding in populations at risk for deficiency, such as newborns and individuals with fat malabsorption syndromes. However, while vitamin K is clearly essential for maintaining overall vascular health, there is limited direct evidence for its use specifically to "support capillaries" in otherwise healthy individuals beyond its established role in coagulation. Most clinical use centers on preventing or treating deficiency states rather than optimizing capillary function per se.

In summary, vitamin K’s support of the capillary system is scientifically validated in the context of preventing abnormal bleeding due to deficiency, but its role in enhancing capillary health in the general population is less directly established.
