Supplement Forms/Alternate Names



Citrus bioflavonoids are compounds found in citrus fruits like tangerines, oranges, and grapefruit. They come in combinations or can be taken individually. Citrus bioflavonoids have been used to improve blood flow and ease swelling in the body. They can be taken as a pill or powder. Citrus bioflavonoids can also be applied to the skin as a cream. They have been used to fight signs of aging.

Safety Notes

It is likely safe to use citrus bioflavonoids on the skin and to take them orally in small doses for a short time. Not enough studies have been done to say whether it is safe to use for a long period. It is also not known whether it is safe to take by women who are pregnant or breastfeeding.
