Quercitin
Quercetin is a bioflavonoid found in fruits, vegetables, and supplements. It is a pigment that belongs to a group of plant compounds called flavonoids and has antioxidant and anti-inflammatory effects that might help reduce swelling, kill cancer cells, control blood sugar, and help prevent heart disease. Quercetin is most commonly used for conditions of the heart and blood vessels and to prevent cancer.
Here are some benefits of quercetin:
- Fighting free radicals
- Reducing inflammation
- Reducing the risk of cancer
- Benefiting neurological health
- Relieving allergy symptoms
- Reducing the risk of infections
- Reducing blood pressure
- Improving exercise performance
- Managing blood sugar levels
There are many case studies and research articles that have been conducted to explore the potential benefits of quercetin. Some of these studies suggest that quercetin can help reduce inflammation, blood pressure, exercise performance, and blood sugar management. Quercetin has also been found to have brain-protective, anti-allergy, and anticancer properties. However, most of these studies have been conducted on animals or in vitro, and more research on humans is necessary to understand the benefits and side effects fully.
The dosage of quercetin used most often is in the range of 250-1000 mg by mouth daily for up to 12 weeks. In some instances, taking more than 1,000 mg of quercetin per day may cause mild symptoms like headaches, stomach aches, or tingling sensations. However, with medical supervision, quercetin has been safely used in amounts of up to 1 gram daily for 12 weeks.
Quercetin is generally considered safe, and there are no known side effects in doses of a few grams a day in either humans or animals. However, quercetin may interact with certain medications, so it is important to speak with a healthcare provider before taking quercetin.
