Hypertensive treatment ongoing, (consult a healthcare professional) Dietary supplement based on dihydrate quercetin, a form of quercetin used in dietary supplements.

Quercetin is part of the flavonoid family, a class of plant pigments belonging to the polyphenol family. Flavonoids are found in many plant sources such as fruits, vegetables, leaves, and grains, and their properties are highly valued for supporting the body.

Present in several medicinal plants including ginkgo and St. John's Wort, it is often derived from Sophora japonica, a tree native to Asia.

A high consumption of quercetin-rich foods such as broccoli, capers, apples, citrus fruits, and onions provides a certain amount of quercetin to the body. However, for full benefits of this substance, quercetin supplementation is recommended.

Benefits of Quercetin as a Dietary Supplement

Anti-allergic effect

With its therapeutic effects, quercetin has proven effective against allergies. Indeed, it acts as a natural antihistamine against seasonal allergies, for example.

For those suffering from eye irritation or other respiratory problems, quercetin has soothing properties.

Antioxidant properties

Quercetin, a powerful flavonoid present in plants, acts as a natural dietary supplement to combat free radicals. This function can reduce the risk of coronary disorders and protect the body from oxidative stress.

Anti-inflammatory effect

Thanks to its biochemical properties, it helps reduce inflammation in the body, especially in those suffering from allergic rhinitis (hay fever).

Its anti-inflammatory action also helps relieve any type of inflammation, such as symptoms of prostatitis (inflammation of the prostate).

Cardiovascular support

May reduce blood vessel permeability, support cardiovascular health, and lower blood pressure in individuals with vascular disorders.
