Flavonoids like quercetin are polyphenols, a type of antioxidant with the additional benefit of anti-inflammatory effects. Antioxidants neutralize free radicals that would otherwise cause damage in your body, increasing the risk of conditions like heart disease, <\/span><span style=\"font-weight: 400;\">cancer<\/span><span style=\"font-weight: 400;\">, or diabetes. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Quercetin is found in the highest concentrations in foods such as capers, onions, apples, berries, grapes, red wine, green tea, and citrus fruits. It\u2019s also available as a supplement. For healthy adults, a daily intake of 500 mg to 1,000 mg of quercetin is <\/span><span style=\"font-weight: 400;\">generally recommended<\/span><span style=\"font-weight: 400;\">. This dosage range is considered <\/span><span style=\"font-weight: 400;\">safe and effective<\/span><span style=\"font-weight: 400;\">, particularly when taken in combination with a balanced, nutritious diet.<\/span><\/p>\n<h2 id=\"how-much-quercetin-should-you-take-daily\"><span style=\"font-weight: 400;\">How much quercetin should you take daily?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Thanks to its antioxidant properties, quercetin has many <\/span><span style=\"font-weight: 400;\">potential<\/span><span style=\"font-weight: 400;\"> benefits, such as <\/span><span style=\"font-weight: 400;\">lowering blood pressure<\/span><span style=\"font-weight: 400;\">, reducing the risk of cardiovascular disease, <\/span><span style=\"font-weight: 400;\">improving cholesterol,<\/span> <span style=\"font-weight: 400;\">preventing allergies<\/span><span style=\"font-weight: 400;\">, killing cancer cells, aiding muscle recovery, and even the potential to <\/span><span style=\"font-weight: 400;\">prevent neurodegenerative disorders like Alzheimer\u2019s disease<\/span><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It\u2019s important to note that taking quercetin supplements will not give you instant relief. <\/span><span style=\"font-weight: 400;\">\u201cIn reality, the beneficial effects of quercetin may take time to manifest and may vary depending on individual circumstances,\u201d <\/span><a href=\"https:\/\/www.linkedin.com\/in\/sean-ormond-443073169\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Sean Ormond<\/span><\/a><span style=\"font-weight: 400;\">, MD, a physician based in Phoenix, Arizona<\/span><span style=\"font-weight: 400;\">.

In other words, even though quercetin is found in food and the supplements are sold over the counter, it\u2019s possible to consume too much.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cA <\/span><span style=\"font-weight: 400;\">common misconception is that because quercetin is a natural compound found in common foods, it must be completely safe to consume in supplement form,\u201d <\/span><span style=\"font-weight: 400;\">explains Dr. Ormond.<\/span><span style=\"font-weight: 400;\"> \u201cWhile natural sources of quercetin are generally safe, concentrated doses in supplement form may have different effects and potential risks.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Specifically, very high doses of quercetin have been investigated for their potential to cause kidney damage and hair loss (though research on hair loss as a direct consequence of excessive quercetin intake is limited). To avoid adverse effects of quercetin supplementation, it\u2019s crucial to adhere to recommended dosages and consult with a healthcare provider, especially when considering higher or more frequent doses.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\t\t<div class=\"singlecare-dynamic-newsletter-wrapper sin-newsletter-wrapper\">\n\t\t\t<span class=\"heading\">Get our allergies newsletter<\/span>\n\t\t\t<form class=\"form-wrapper\" data-newsletter-form=\"1\" data-subsource=\"Allergies Newsletter\">\n\t\t\t\t<div class=\"input-wrapper\">\n\t\t\t\t\t<label for=\"dynamic-email\">Email<\/label>\n\t\t\t\t\t<input type=\"email\" id=\"dynamic-email\" class=\"email\" required>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"input-wrapper\">\n\t\t\t\t\t<input class=\"submit-form-btn\" type=\"submit\" value=\"Click to sign up\">\n\t\t\t\t<\/div>\n\t\t\t<\/form>\n\t\t\t<p class=\"success-message\" aria-live=\"polite\"><\/p>\n\t\t<\/div>\n\t<\/span><\/p>\n<h2 id=\"when-is-the-best-time-of-day-to-take-quercetin\"><span style=\"font-weight: 400;\">When is the best time of day to take quercetin?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">You can take quercetin at any time of day. However, you should consider taking it at mealtimes because foods containing vitamin C, bromelain, and healthy fats can aid its absorption. Additionally, \u201c<\/span><span style=\"font-weight: 400;\">some individuals may prefer to take it with meals to minimize potential gastrointestinal discomfort,\u201d says Dr. Ormond. Taking quercetin on an empty stomach can increase the risk of potential side effects such as nausea. Plus, syncing your dose with your breakfast or dinner makes it part of your daily routine, which can help with consistency\u2014an important part of any supplement\u2019s effectiveness.

Notably, it may enhance the effects of blood thinners like warfarin, raising bleeding risks. It can affect the metabolism of medications processed by the cytochrome P450 enzyme system, including certain antibiotics (like <\/span><a href=\"https:\/\/www.singlecare.com\/prescription\/ciprofloxacin\"><span style=\"font-weight: 400;\">ciprofloxacin<\/span><\/a><span style=\"font-weight: 400;\">) and chemotherapy agents.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">People with kidney disease or those pregnant or breastfeeding are advised against using quercetin due to potential risks and the lack of safety data.<\/span><\/p>\n<h2 id=\"bottom-line\"><span style=\"font-weight: 400;\">Bottom line\u00a0<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Overall, the recommended daily intake of 500 mg to 1,000 mg\u2014especially when paired with vitamin C, bromelain, and healthy fats\u2014optimizes its effectiveness while minimizing potential side effects associated with higher doses. However, individuals should exercise caution and consult healthcare professionals before starting supplementation to navigate any possible interactions or contraindications based on personal health conditions or medication use. With mindful incorporation into one&#8217;s routine and adherence to advised dosages, quercetin can be a valuable addition to achieving overall wellness.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Quercetin is a flavonoid, a type of natural plant pigment that helps to give fruits, vegetables, and flowers their color.
