Rating (out of 5): 3

Hesperidin, a flavonoid primarily found in citrus fruits, has been used both traditionally and in modern practice to support vascular health, particularly in conditions involving capillary fragility or weakness. The scientific rationale for its use is based on its ability to strengthen capillary walls and reduce their permeability. Several clinical studies have investigated the effects of hesperidin, often in combination with diosmin, in the treatment of chronic venous insufficiency and related disorders such as hemorrhoids and varicose veins. These conditions commonly involve symptoms linked to capillary weakness, like easy bruising, edema, and the formation of petechiae.

Research suggests that hesperidin helps stabilize capillary membranes, decreases capillary permeability, and improves microcirculation. For example, randomized controlled trials have shown that micronized purified flavonoid fractions (containing hesperidin and diosmin) reduce symptoms such as swelling and discomfort in patients with venous insufficiency, which is partly attributed to their action on capillaries. Additionally, hesperidin exhibits antioxidant and anti-inflammatory properties, which may further protect vascular tissue from damage.

While most studies use hesperidin in combination with other flavonoids, and direct evidence for isolated hesperidin in capillary fragility is limited, the overall body of evidence supports its utility in managing symptoms related to capillary weakness. However, it should be noted that more high-quality, large-scale clinical trials focusing specifically on capillary fragility are needed to fully establish its efficacy for this indication.
