Taxifolin (also known as dihydroquercetin) is a flavonoid found in various plants, including larch trees and milk thistle. Its use to support the veins and vascular system is supported by a growing body of preclinical and early clinical research. Taxifolin exhibits potent antioxidant, anti-inflammatory, and vascular-protective properties. In vitro and animal studies have shown that taxifolin can protect endothelial cells, reduce oxidative stress, and improve microcirculation. These effects are relevant because oxidative damage and endothelial dysfunction are key factors in the development of chronic venous insufficiency and varicose veins.

A handful of small-scale clinical trials, mostly conducted in Russia and Eastern Europe, have reported that taxifolin supplementation may improve symptoms such as leg swelling, heaviness, and microcirculatory disturbances in patients with chronic venous disorders. However, these studies are limited in size, often lack rigorous controls, and are not widely cited in Western medical literature. While the mechanism of vascular support is plausible and some positive results have been observed, large, well-designed human trials are still lacking.

In summary, there is scientific rationale and some early evidence supporting the use of taxifolin for vein health, but more robust clinical validation is needed before strong conclusions can be drawn. The evidence currently rates as moderate (3/5).
