Boost the antioxidant defense of your cardiovascular system and the whole body with the natural power of Swanson Quercetin, which helps fight the free radicals. Quercetin is a natural antioxidant, a flavonoid, found in onions, apples, green tea, and other plant sources. Quercetin provides valuable protection from free radicals to your blood vessels and other vital tissues in the body.

The useful effects of flavonoids, such as quercetin, derive from their ability to function as antioxidants in the body. Antioxidants are compounds that can bind to and neutralize free radicals. Free radicals are unstable molecules that can cause cellular damage if their level becomes too high. Damage caused by free radicals is linked to numerous chronic conditions. Quercetin is the most common flavonoid in food. It is estimated that the average person daily ingests 10-100 mg of quercetin from different food sources, which is not enough, so quercetin should be added as a supplement.

It can decrease inflammation in the body

Free radicals can do more than simply damage your cells. Research shows that high levels of free radicals can activate genes that stimulate inflammation. High levels of free radicals can cause an increased inflammatory response. While a certain level of inflammation is needed to treat and combat infections, persistent inflammation is linked to medical problems (cardiovascular disorders, kidney disorders). Research shows that quercetin can help alleviate inflammation. An 8-week study with 50 women with rheumatoid arthritis showed that participants who took 500 mg of quercetin perceivably reduced morning rigidity and pain after physical activity.

Can quercetin increase athletic performance?

Various minor studies confirmed that quercetin helps to improve vo2max, increase aerobic capacity, and increase time to fatigue. The differences are minimal, but they can be important in critical moments when every second matters. 

Can quercetin help reduce high blood pressure?

According to the study of the American Heart Association from 2016, taking quercetin as a dietary supplement is an effective way to reduce blood pressure. Other studies have shown that overweight persons who took 150 milligrams of quercetin per day had lower levels of bad cholesterol in the blood and also lower systolic blood pressure, which measures the pressure in the blood vessels during the heartbeat.

Quercetin also has the potential to preserve normal levels of blood sugar, alleviate problems related to aging, reduce blood pressure, and improve cognitive functions. For the last potential of quercetin, unfortunately, only studies on animals have been performed.

More on flavonoids

Flavonoids - or bioflavonoids, if you prefer - are natural compounds that are widely present in the vegetal world. Flavonoids are a large group of phenolic compounds, composed of more than 6000 different molecules. Bioflavonoids can perform various biological activities, which can be very useful to the body. This is why these compounds are considered important for health. Among the features of flavonoids that arouse interest are definitely their antioxidant characteristics, protection of microcirculation, and anti-inflammatory effect.
