Anthocyanins are naturally occurring flavonoid pigments found in fruits like berries, cherries, and grapes. Their use for varicose veins is supported by a moderate level of scientific evidence. Anthocyanins exhibit potent antioxidant and anti-inflammatory properties, which are thought to improve vascular health. Several preclinical and clinical studies have explored the effects of anthocyanin-rich extracts (such as those from bilberry and grape seed) on venous insufficiency and varicose veins.

Anthocyanins are believed to strengthen capillary walls, reduce capillary permeability, and promote microcirculatory blood flow. Studies have shown that supplementation with anthocyanin-rich extracts can reduce symptoms such as leg swelling, heaviness, and discomfort associated with chronic venous insufficiency (CVI), a condition closely related to varicose veins. For example, randomized controlled trials using Vaccinium myrtillus (bilberry) extract have demonstrated improvements in venous tone and a reduction in edema.

However, most clinical studies involve complex extracts containing anthocyanins rather than purified compounds, and sample sizes are often small. While these results are promising, more robust, large-scale trials are needed to confirm efficacy and clarify dosing. In summary, the use of anthocyanins for supporting venous health and treating symptoms of varicose veins is grounded in some scientific research, but the overall strength of evidence is moderate at best.
