The name quercetin may not sound familiar to you, but the possible benefits it offers will. This plant flavonoid is found in many types of seeds, flowers, fruits, and vegetables, and it has antioxidant properties. Antioxidants are known for protecting cells from the possible damage of free radicals. And while the claims about quercetin's health benefits have limited scientific backing, some clinical studies have shown it's capable of reducing inflammation, which can occur with many health conditions and diseases.
In addition to getting quercetin from eating a healthful diet that includes a variety of plant-based foods, it can be consumed in the form of supplements. Available in capsule, powder, and liquid forms, quercetin supplements are formulated with flavonoids, vitamins, and plant extracts. Although these supplements should never be taken in place of medical advice or prescribed medications, they may help ease various symptoms of different ailments by calming inflammation in the body.
There are a lot of quercetin supplements on the market. We are here to help with our top picks and our informative shopping guide.
Flavonoids are molecules found in plants that benefit cells by strengthening them and protecting them from damage caused by free radicals. Most fruits and vegetables contain these compounds, which also give them their colors — yellow lemons, white onions, and red raspberries are some examples. Quercetin is one of these flavonoids, or plant pigments, that is rich in antioxidants.
In order to understand how taking a quercetin supplement may be beneficial to your health, it’s important to understand how antioxidants work.
Free radicals are molecules that can damage cells, potentially leading to numerous diseases, including cancer and heart disease. They form in the body as a result of the metabolic process, primarily when poor diets that consist of trans fats, processed foods, and excessive amounts of sugar are consumed. Environmental factors can also cause free radicals to develop, such as exposure to pollution, radiation, cigarette smoke, and various chemicals. A high level of free radicals in the body can lead to a process called oxidative stress, which in turn can lead to inflammation and various symptoms, ailments, and diseases.
One of the jobs of antioxidants is to tackle free radicals and reduce or eliminate their ability to cause cell damage. Antioxidants are found in numerous types of healthful foods, such as fruits, vegetables, grains, and seeds. They are also available in high concentrations in dietary supplements like quercetin.
The possible anti-inflammatory benefits of taking an antioxidant-rich supplement like quercetin may also ease symptoms and provide protection against developing certain diseases. That’s because inflammation is thought to play a role in causing these conditions. While quercetin supplements aren’t miracle cure-alls, here are some health concerns and how they may help.
Remember that taking quercetin supplements alone won’t prevent or cure health problems, nor will it provide total protection against inflammation. But combining them with a balanced diet that includes other fruits, vegetables, and whole grains will likely improve your antioxidant intake and give your body a disease-fighting boost.
As you explore the different brands and formulations of quercetin supplements, you will find capsule, powder, and liquid forms. Capsules have slick coatings that make them easy to swallow. A few brands make chewable formulas for children. Powdered quercetin is made to be mixed into beverage form, or it can be added to food. Liquid supplements are available in drops and sprays.
Some quercetin supplements are formulated with other ingredients, including extra flavonoids and plant extracts, to boost their antioxidant effects. For example, bromelain, an enzyme that comes from pineapple stems, is often added to quercetin supplements to enhance absorption. Vitamin C is another common addition that can help boost immunity.
Many quality brands of quercetin are made without GMO products, preservatives, artificial additives, sugar, gluten, or animal products.
The dosage of quercetin varies depending on the brand and strength, but for most products, the recommendation is two capsules per day. However, some high-strength options only require one dose daily.

Q. What does the FDA say about quercetin supplements?
A. The FDA doesn’t monitor dietary supplements for safety or make claims or recommendations about their uses to treat medical conditions. However, some clinical and scholarly studies of quercetin support its ability to reduce inflammation.
Q. Should some people avoid taking quercetin supplements?
A. Quercetin oral supplements aren’t likely to cause adverse reactions or side effects in most people, but some individuals have reported digestive upset after taking it. Other possible side effects include tingling sensations in the extremities and headache. In addition, some people with high blood pressure may experience an increase in heart rate when taking high doses of bromelain. If this is a concern, a quercetin supplement without bromelain should be chosen. Pregnant or nursing women shouldn’t take quercetin.
Q. How much quercetin should I take each day?
A. If you are new to taking quercetin, it’s best to begin with a low dose. Adults can start by taking 500 milligrams once a day and increasing to twice daily.

Additionally, extremely high doses taken over extended periods of time could cause kidney trouble.
