Citrus Bioflavonoids Extract Facts

Citrus bioflavonoids are a group of naturally occurring plant compounds found in citrus fruits such as oranges, lemons, limes, and grapefruits. They belong to a larger class of phytonutrients called flavonoids, which are responsible for many of the color, taste, and health-supportive properties of fruits and vegetables. In the body, citrus bioflavonoids are known for supporting antioxidant activity, vascular health, and overall wellness.

Key Benefits of Citrus Bioflavonoids Extract:

Citrus bioflavonoids offer broad benefits:

  • Works synergistically with vitamin C to support normal immune system activity.
  • May support collagen formation and tissue integrity, which are important for healthy skin, gums, and connective tissue.
  • Provide antioxidant activity that helps the body stay resilient against everyday stressors.


Why it Matters:

Vitamin C is essential for immune defense and collagen formation, but up to 40% of adults fall short on intake ¹. Bioflavonoids help vitamin C work more effectively, amplifying these benefits.
Daily stressors, diet, and environmental exposure generate free radicals. Bioflavonoids add antioxidant support that helps maintain normal cellular balance and tissue health.
Found naturally in citrus peels, they are hard to obtain in meaningful amounts from a modern diet, since most people consume the fruit pulp but discard the peel.
