Bioflavonoids, often known simply as flavonoids, are a class of very powerful phytochemicals. They have their own impressive health benefits but they also help the body get the most out of the vitamin C you have consumed. While there is a variety of different bioflavonoids, they are all water-soluble, like vitamin C.

Research in the U.S. shows that bioflavonoids have a great range of medicinal actions including antiviral, anti-inflammatory, antioxidant and antitumor properties.

Citrus bioflavonoids are powerful antioxidants derived from citrus fruits. The antioxidant properties of flavonoids have been recognized for more than 40 years. Like other antioxidants, these compounds reduce oxidative stress, which in turn reduces inflammation, pain, and your susceptibility to disease. Increasing intake of bioflavonoids helps prevent free radicals from causing harm in the body. The antioxidant and anti-inflammatory benefits of citrus bioflavonoids have been shown to support metabolic, circulatory, cognitive, and joint health.

Citrus bioflavonoids support balanced immune cell activity for better immune response, and support for respiratory health. They also have a synergistic function with vitamin C for enhanced immune support, and have been shown to increase absorption of vitamin C.
