Bioflavonoids, or simply flavonoids, are compounds found in almost all fruits and vegetables. You may have heard of them from health and wellness articles, research studies, and the labels of your favorite supplements! But, what exactly are they and what are they good for?
What Are Bioflavonoids:
Citrus bioflavonoids can be found in citrus fruit flesh and rinds, such as oranges, lemons, limes, and grapefruits. Flavonoids in these fruits are responsible for their color and taste. Also, citrus bioflavonoids have a special relationship with Vitamin C. They work together to strengthen their antioxidant and immune health function7. Additionally, Vitamin C has also been shown to absorb quicker with citrus bioflavonoids7.
What Do Bioflavonoids Do?
Over 6,000 unique bioflavonoids have been identified and studied for their roles in promoting health.1 From the mid-1930s to the mid-1950s, bioflavonoids were known as Vitamin P even though they are not technically vitamins. However, studies over the years have shown them to have antioxidant and anti-inflammatory healing properties attribute to nutrients classified as vitamins.
There are over 10 types of citrus bioflavonoids2 and each of them have been researched to promote healing and preventative health benefits. Here are several of the more common bioflavonoids in citrus fruits and peels:
- Quercetin: helps fight inflammation, allergens and free radicals2
- Diosmin: supports healthy capillary function and circulatory function3
- Rutin: promotes a defense against allergens, inflammation, carcinogens, and malignant cells4
- Tangeritin: promotes cellular strength and defends against free radicals.5
- Naringin: promotes cardiovascular health by defending against common risk factors (e.g. cholesterol, hypertension, obesity).6
- Hesperidin: promotes healthy cholesterol levels, defends against inflammation and free radicals2
The antioxidant and anti-inflammatory benefits of citrus bioflavonoids have also shown to support metabolic, circulatory, cognitive, joint health and respiratory health in research studies. Additionally, they can be ingested in different forms due to their natural preservative and suspension qualities.7
