Scientists are still discovering all of the ways flavonoids work.

Research shows that they can act as an antioxidant and may also have anti-inflammatory, antimutagenic, and anticancer effects. All of these effects mean that flavonoids can help protect cells from harmful chemicals.

One of the most widely discussed benefits of flavonoids is their antioxidant properties. This means that flavonoid compounds can neutralize harmful cells in the body that may cause a range of damage.

Flavonoids can also prevent cell growth, which means they are sometimes used in cancer treatments. They are a vital part of many medicines and treatments for certain illnesses, and many manufacturers include them in cosmetics and anti-aging products.

There are six types of flavonoid. Different foods contain different types.


This group of flavonoid has antioxidant properties and can help prevent vascular disease. Flavonol-rich foods and drinks include:


Flavones have antioxidative, anti-inflammatory, and anticancer properties. Flavone-rich foods include:


Flavanones can effectively neutralize harmful cells in the body. They are generally found in citrus fruits. Flavanone-rich foods include:


Isoflavonoids have properties that help treat and prevent various diseases and improve vascular health. Foods containing isoflavonoids include:


Also called flavanols and catechins, this subtype of flavonoid is commonly found in nutrient-rich foods. Foods containing flavan-3-ols include:


Anthocyanins are the pigments that make up the colors in plants, fruits, and flowers. They may be beneficial for cardiovascular health. Foods rich in anthocyanins include:

A nutrient-dense, balanced diet typically provides all the flavonoids a person needs.

Some people choose to take certain supplements to increase their flavonoid intake. This may be because a person is unsure whether they are getting enough flavonoids in their diet, or because they think this will improve their health.

According to a 2015 review, five subgroups of flavonoids have been found to help lower blood pressure. This can provide benefits such as improving heart health and protecting the kidneys.

Additionally, some research suggests that flavonoids may have a use in the prevention and treatment of cancer. Research into the safe use of flavonoids to treat cancer is ongoing.

Flavonoids are a group of natural compounds found in fruits, vegetables, and other plants. The antioxidative properties of flavonoids are vital in the research concerning their potential beneficial health effects.

Research is ongoing into the potential benefits of consuming flavonoids, but they are already an important component in many medicines and medical research.

A person can typically maintain a sufficient intake of flavonoids by eating a nutritious, balanced diet that includes flavonoid-rich foods.
