Quercetin is a flavonoid, a natural pigment present abundantly in many fruits, vegetables, and red wine. It’s anti-inflammatory, and antioxidants help to prevent several diseases. Quercetin is known to control blood sugar, help reduce swelling, kill cancer tissues, prevent bladder infections and heart diseases. Humans cannot make Quercetin in their bodies. Hence, they take it in supplements or add fruits, vegetables, and plants containing the natural pigment in their diet as it functions as antioxidants within the body. Antioxidants bind and neutralize free radicals. When free radical levels are high, they cause cellular damage, linked to several chronic diseases. In addition to this, the antioxidants properties in Quercetin helps to reduce inflammations and allergies.
Foods contatining Quercetin

Why is Quercetin essential for our body?
The antioxidants and anti-inflammatory properties of Quercetin helps to manage a variety of infections that include the following
- Heart problems
- Blood vessels problems
- Control Blood Pressure
- Respiratory infections
Limited studies state that consuming quercetin-rich foods lowers the risk of heart diseases in older men, reduces cancer risk, and decreases prostate infection pain. Although research for killing cancer cells in animal models is promising, the study is still flourishing in human trials.
Athletics take Quercetin to improve their endurance performance. Although animal studies are compelling, humans’ studies are less promising. The most significant benefit for them is protection from URI after intense workouts.
Generally, the studies that state the effectiveness of Quercetin is on animals or in cell cultures. More research is needed to get to the benefits of Quercetin in humans when taken as supplements.
Quercetin dosage information
You can purchase Quercetin supplements online or at a physical store. It is available in the form of capsules and powders. Typically, the dosages of the supplements range from 500mg to 1000mg. Still, the absorption capacity is comparatively less as it has low bioavailability. That is why Quercetin is clubbed with other supplements like Vitamin C or Bromelain, a digestive enzyme to increase absorption. In addition, Quercetin tends to show a synergistic effect when clubbed with flavonoid supplements like resveratrol, catechins, and genistein.
Risks and Side Effects of Quercetin
When Quercetin-rich foods are consumed, it is likely to be safe other than getting the amounts through supplements. Also, the supplements are safe when reasonable doses like 500mg daily for a limited period of only 12 weeks. However, risks and side effects tend to increase when taken for more extended periods and taking high doses of Quercetin like 1000mg. The most common side effects are headache, tingling sensation in arms and legs, and nausea.
Moreover, FDA does not regulate supplements. Quercetin interacts with other medications and supplements, so it is essential to let your doctor know to check on the associated potential risk before taking this supplement.
Benefits of Quercetin
Protect from free radicals
Quercetin has antioxidant properties and is powerful than Vitamin C, Vitamin E properties. Antioxidants protect our body from free radicals, which are unstable molecules that increase the risk of infections. The mechanical life we are living in today and stress factors contribute to more radicals, including pollution, smoking, drinking, radiation, and chemical toxins.
Inflammations help our body heal from infections, but persistent or chronic inflammations tend to be harmful and contribute to serious health issues, including cancer, heart and kidney diseases. Research studies claim that in male athletes, Quercetin lowers inflammations, showing anti-arthritis properties. But it did not prove to be positive in females with rheumatoid arthritis.
Lowers down the cancer risk
Quercetin is rich in antioxidants, hence may contain anti-cancerous properties that help prevent the risk of cancer. Research studies have shown that intake of foods rich in Quercetin help to prevent the spread of tumor cells, reducing the risk of many types of cancer. Though test tube and animal studies are promising with proven results of Quercetin suppressing the cell growth of cancer cells in the liver, lung, breast, prostate, colon, blood, and adrenal, human studies are required to recommend Quercetin as a medication for cancer.
Prevent neurological disorders
Neurodegenerative diseases like Alzheimer’s and Parkinson’s occurs by oxidative stress when there is an imbalance in free radicals. Quercetin‘s antioxidants properties help fight oxidative stress caused by free radicals. The research studies on rat quercetin lower oxidative stress and prevent the toxic effect of metals on the nervous system.
The anti-inflammatory properties of Quercetin may provide relief to allergic symptoms. Test tube research studies on animals found that Quercetin suppresses the enzymes involved in inflammations. In addition, studies on rats and mice proved that the supplement stopped the peanut-related anaphylactic reactions when given. Yet, the research studies are in progress to recommend the medicine as anti-allergic medication to confirm that the compound has the same effect on humans as that on mice.
Prevents bacterial and viral infections
The anti-bacterial properties of Quercetin are effective against the bacteria types that cause infections in the stomach, intestines, skin, respiratory and urinary. In addition, Quercetin with other flavonoids prevents viral infections caused by adenovirus, herpes simplex, and Japanese encephalitis.
Controls blood pressure
Quercetin supplements work a great way of controlling blood pressure. Research studies showed that 150mg of Quercetin per day decreases the harmful cholesterol levels in the blood, thereby reducing the systolic blood pressure. Although the studies are impressive, more studies on human studies are required for prescribing Quercetin actively for controlling the high blood pressure levels.
Generally, Quercetin is safe as a supplement with little or no side effects. However, its interactions with other medications are alarming factors for pregnant, breastfeeding women, and people with chronic diseases. Therefore, it is advisable to talk to the doctor before using the supplements.
