Rutosides, also known as rutin, are a group of flavonoid compounds found in various plants, most notably in buckwheat, citrus fruits, and certain berries. Their use to support the capillaries and vascular health has been investigated in both traditional and scientific contexts. Scientific studies suggest that rutosides exhibit antioxidant, anti-inflammatory, and vasoprotective properties. Clinical trials, particularly in Europe, have examined their efficacy in treating chronic venous insufficiency, capillary fragility (such as in patients with purpura or easy bruising), and hemorrhoids.

In these studies, rutosides have been shown to reduce capillary permeability and increase capillary resistance, which can help decrease swelling (edema) and improve symptoms related to weak capillaries. The European Medicines Agency recognizes rutosides as a traditional herbal medicinal product for the relief of symptoms of chronic venous insufficiency, based on a well-established use in Europe. Some randomized controlled trials have demonstrated modest improvements in symptoms like leg swelling and discomfort.

However, the overall quality of evidence is moderate, with some studies limited by small sample sizes or methodological weaknesses. Thus, while rutosides are not a miracle cure, there is a reasonable scientific basis for their use in supporting capillary health, especially as an adjunct to other therapies. More rigorous, large-scale studies would help clarify their efficacy further.
