Diosmin is a natural compound belonging to the group of flavonoids, which are known for their effects on various biological processes in the human body. It is most often extracted from citrus fruits, especially their peels, where it is found in association with other flavonoids such as hesperidin. Chemically, it belongs to the glycosides, which means that it contains a sugar part that affects its solubility and absorption in the body.

Diosmin is a natural substance for the human body that enters the body primarily through diet, although its concentrations in common foods are relatively low.

After ingestion, diosmin undergoes a process of metabolism in the digestive tract, where it is converted into its more active form – diosmetin. This transformation takes place mainly in the intestines under the influence of intestinal microflora, which cleaves the glycosidic bond and allows for its better absorption into the bloodstream.

Diosmetin then enters the liver, where it undergoes further stages of metabolism, converting it into various compounds that are further distributed throughout the body or excreted in urine and bile. This process is important for its bioavailability, as not all flavonoids are equally well absorbed and utilized by the body.

In the body, diosmin interacts with the vascular system, especially capillaries and veins. It influences some biochemical processes related to the permeability of the vascular wall and blood circulation in small vessels.

This property is associated with its influence on certain enzymes and cellular mechanisms that regulate vascular structure and function. Diosmin is also the subject of research focused on its interaction with various proteins in the body that affect the structure of vascular tissues.

Because of these properties, it is often combined with other flavonoids, such as hesperidin, which may enhance its absorption and effectiveness in the body. Additionally, some forms of diosmin are micronized, meaning they are processed into smaller particles to improve their solubility and bioavailability.

Since flavonoids are a natural part of plant foods, diosmin is also found in some foods, although in smaller amounts. It is mainly present in citrus fruits, but in the normal diet it is consumed in amounts that may not be sufficient to achieve significant physiological effects. Therefore, it is often extracted and used in higher concentrations in various forms.

Diosmin is also interesting in terms of its excretion from the body. The main part is metabolized in the liver and excreted in the urine, while a certain proportion can also enter the bile and subsequently in the feces. This process depends on individual factors such as metabolic rate, liver health and kidney function. The rate of elimination of diosmin from the body is also influenced by its chemical structure, which determines how easily it binds to various transport mechanisms in the body.
