Allergies Home > Quercetin Supplements
Quercetin is a flavonoid found in a variety of different plants and is claimed to provide several health benefits. Although quercetin can be obtained through eating certain fruits and vegetables, supplements containing quercetin are also available.
Quercetin appears to have numerous different actions that could contribute to its medicinal activity. It seems to work as an antioxidant and may also have anti-inflammatory effects. It might inhibit the growth and division of certain cells, including cancer cells, and may have anti-estrogen effects (which could possibly contribute to some effect on hormone-related cancers, such as breast cancer). For allergies, quercetin might work by inhibiting the release of histamine.
Some people may be more likely to experience problems due to the supplements. Therefore, you should talk with your healthcare provider prior to taking quercetin medicinally if you have:
- Kidney disease, such as kidney failure (renal failure)
- Any chronic or severe medical condition
- Any allergies, including allergies to foods, dyes, or preservatives.
