Ongoing treatment for high blood pressure (ask a healthcare professional for advice)Dietary supplement based on quercetin dihydrate, a form of quercetin used in dietary supplements.

Quercetin is a member 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.

Found in many medicinal plants, including ginkgo and St. John's wort, it is often derived from sophora japonica, a tree native to Asia.

High consumption of quercetin-rich foods such as broccoli, capers, apples, citrus fruits and onions can provide the body with a certain amount of quercetin. However, to benefit from all the properties and advantages of this substance, quercetin supplementation is recommended.

The benefits of quercetin as a dietary supplement

Anti-allergic effect

With its therapeutic effects, quercetin has proven its effectiveness against allergies. In fact, 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 found 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, particularly in those suffering from allergic rhinitis (hay fever).

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

Cardiovascular support

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