What are flavon glycosides?

Flavon glycosides are flavonoids bound to one or more sugar molecules. The sugar affects solubility, absorption, and how the compound is metabolized in the body.

What are the main benefits of flavon glycosides?

They are best known for antioxidant activity and may help modulate inflammatory pathways. Some flavon glycosides may also support vascular function and overall cardiovascular health.

What foods contain flavon glycosides?

They occur widely in fruits, vegetables, and many herbs. Common dietary sources include plant foods with strong color or bitterness, as well as herbal preparations.

What is a typical dosage for flavon glycosides supplements?

A common supplemental range is about 200–500 mg per day, depending on the specific product and extract. Follow the label and consider medical advice if you have health conditions or take medications.

Description

Flavon (flavonoid) glycosides are a large class of natural compounds composed of a flavonoid backbone linked to sugars. Present in a wide range of fruits, vegetables, and herbs, they're valued for antioxidant properties and potential roles in supporting cardiovascular and inflammatory health.

benefits

Main effects with level of evidence

Moderate

Note on evidence

Evidence mainly comes from clinical studies on standardized extracts and observational data; most benefits are supported by preclinical and some human research.

Antioxidant Protection

Moderate

Flavon glycosides reduce oxidative stress by neutralizing free radicals, potentially protecting cells from damage linked to aging and chronic disease.

History of hypersensitivity to plant polyphenols
Pregnancy or lactation without medical guidance

interactions

Important interactions between active ingredient ↔ supplement / medication / food

Flavon glycosides can interact with drugs affecting blood clotting and may alter bioavailability of some medications.
