Problems Formulating With Quercetin
Improving the bioavailability of quercetin is a highly sought-after benefit to brands trying to formulate with quercetin and consumers who want effective results and smaller pills.
Our Solution: SunActive IsoQ
Water-Soluble Quercetin
SunActive® IsoQ is derived from rutin, which is extracted from the dried flower buds of the Japanese Pagoda tree using a solvent-free, enzymatic process. The result is a water-soluble dietary ingredient, chemically identical to isoquercitrin found in nature.
This solubilized form of quercetin is 25 times more bioavailable than quercetin itself. This high bioavailability is achieved through an encapsulated matrix that makes it completely water soluble, enabling it to reach the gut where it is converted to quercetin and rapidly absorbed by the gut lining.
SunActive® IsoQ contains the equivalent of at least 11% quercetin, which means that 100 mg of SunActive® delivers an equivalent of 275 mg of quercetin in the body.
SunActive® IsoQ is Generally Recognized as Safe (GRAS) by a panel of independent experts, Kosher, vegan and Informed Ingredient certified.
Is Quercetin Water Soluble?
Most quercetin products are not water soluble because quercetin itself is not soluble. This affects bioavailability. Improved solubility means versatile formulation and increased bioavailability. Some formulators counter the solubility issue by using SunActive® IsoQ, a water-soluble form of isoquercitrin.

It is a fully soluble replacement for standard quercetin to lower dose size in all formulas. It is ideal for multi-ingredient formulas, and formulations requiring soluble ingredients. Plus, SunActive® IsoQ’s higher bioavailability allows for smaller doses to deliver desired quercetin benefits. Formulators can replace a standard 500 – 1,000 mg dose of regular quercetin with just 180 – 360 mg of SunActive® IsoQ.
