Bordas’ Diosmin: an active ingredient for vascular health

12 Feb 2026

With the arrival of spring and rising temperatures, circulation-related discomforts such as heaviness or tiredness in the legs are common. Diosmin, a natural flavonoid derived from citrus and micronised, is a key ingredient for vascular wellbeing.

What is Diosmin and Why is it Important for Circulation?

Diosmin is a natural flavonoid obtained from citrus fruits. Its relevance in vascular care lies in its ability to improve venous tone, favour venous return, and support the proper functioning of microcirculation.

From a physiological standpoint, Diosmin acts primarily on the venous system, helping to reduce capillary hyperpermeability and protect blood vessels from oxidative stress.

Seasonal Application: Spring and High Temperatures

Heat causes vasodilation, which can worsen the sensation of tired legs. Spring is an ideal time to support vascular wellbeing by incorporating active ingredients such as Bordas Diosmin into preventive and maintenance formulations.

As leading manufacturers at the European level, Bordas’ ability to adapt allows Diosmin to be applied in a stable and efficient manner across different formats and formulation strategies aimed at vascular wellbeing, both for continuous and seasonal use. Its natural origin and technical profile make it a benchmark active ingredient within citrus flavonoids.

The high-quality standards imposed by Bordas ensure that Diosmin has a good safety profile and generally high tolerability when used in accordance with usual recommendations.

Mechanism of Action in the Vascular System

This flavonoid contributes to an improved response of the vascular system, particularly in individuals experiencing circulatory issues in the legs, a situation that often intensifies with the heat.

• Relief for tired legs: Diosmin helps reduce symptoms such as heaviness, tightness, and oedema in the lower limbs, particularly those associated with chronic venous insufficiency.
• Improvement of venous return and microcirculation: Its venotonic and capillary-protective action allows for more efficient circulation, contributing to daily vascular comfort.
• Synergy with other citrus flavonoids: In many formulations, Diosmin is combined with other flavonoids, such as hesperidin, enhancing its benefits and broadening its spectrum of action.

The Importance of Bioavailability: Micronised Diosmin

Not all Diosmins behave in the same way within the body. Bordas’ Micronised Diosmin undergoes a technological process that reduces particle size, allowing for improved absorption and bioavailability.

Clinical evidence shows that micronised formulations are more effective, as the body can better absorb and utilise the active ingredient. For this reason, Bordas’ Micronised Diosmin is particularly suitable for formulations aimed at the relief of tired legs and continuous vascular care.

Preparing for Summer: Vascular Wellbeing from Within
