What’s the Best Form of Quercetin and Where to Buy It


Quercetin is a bioactive plant-based pigment with antioxidant properties and anti-inflammatory properties that offers various health benefits. The effects of quercetin may vary. It is believed to help reduce inflammation associated with chronic disease, promotes cardiovascular health, lowers the risk of heart disease, eases allergy symptoms, promotes antiviral effects, supports the immune system, and lowers blood pressure. It may also decrease the risk of cancer and chronic brain disorders.

The pigment is found in several food products, but if you are not getting enough in your diet, you may consider taking a gluten-free, high-quality dietary supplement. 

Not all quercetin supplements are created equal. You must consider the form of quercetin you are taking in regards to the absorption of quercetin, as well as where to buy quercetin. This article will review the potential benefits of quercetin and your options to ensure you find a quercetin product that helps you reach your wellness goals.

Which Form of Quercetin is Best?

Consumers should invest in highly absorbable quercetin products.  Here’s a rundown of the various forms of quercetin and the level of bioavailability you can expect.

  • Quercetin Rutinoside (Rutin): This product has low bioavailability and may cause irritation and allergy symptoms.
  • Quercetin Chalcone: This form of quercetin is a hesperidin meaning it has antioxidant and anti-inflammatory effects. Unfortunately, it has an exceptionally short half-life and will not provide benefits unless it is taken every half hour.
  • Quercetin Dihydrate: This type of quercetin is insoluble in water but is fat-soluble and highly bioavailable. It seems to be the quercetin type with the highest bioavailability.

Other quercetin forms with bioavailability that range between dihydrate and rutin forms include glycosides and aglycone.

Bioavailability is also affected by the form of supplement you are taking. Some supplements have additives and formulations that make them more bioavailable. For example, quercetin phytosome supplements provide optimal absorbability.

Where to Buy Quercetin

Quercetin is available online and in brick-and-mortar drug store locations. Purchase it from a trusted provider to ensure its purity and potency. Both the brand and retailer should have stellar reputations.

  • Sustainable Manufacturing: Environmental consumers may prefer to source quercetin and other supplements from a brand that follows sustainable manufacturing methods. Look for a GMP-certified brand that uses recyclable and biodegradable packaging to ensure eco-friendliness.
