Certified Naturals™ Bioavailable Quercetin Capsules features Quercefit®, the most researched quercetin form on the market. Quercefit® has solved the absorption issues associated with quercetin and has demonstrated benefits for relief of allergy symptoms, histamine reaction, asthma, viral infections and improving athletic performance in clinical settings.

What is Quercetin?

Flavonoids are organic compounds found in plants. They act as antioxidants and antimicrobial agents that help plants grow and defend themselves. Quercetin is a specific flavonoid from the flavonol sub-group.

Quercetin is abundant in nature and can be found in many of the plant-based foods that humans consume. Onions, tomatoes, apples, berries, grapes, peppers, tea, seeds, nuts, flower buds and capers all contain quercetin. Most of us do get some quercetin daily, but the amount is not high enough to fully capitalize on its many health benefits. On average, human’s intake less than 14 mg of quercetin in the daily diet.

The major challenge in unlocking the benefits of quercetin is its poor absorption. Quercetin has poor solubility in water and is inefficient in crossing cellular membranes into the bloodstream. Studies indicate that only 1-2% of quercetin consumed orally by humans is absorbed by the body.

Quercefit® - the most absorbable form of quercetin

Using Phytosome® technology to complex quercetin sourced from the flower buds of the Japanese Pagoda plant (Sophora japonica L.) with sunflower sourced lecithin, significantly improved absorption has been achieved. This phospholipid complex known as Quercefit® is the chosen source of quercetin used in the Certified Naturals® Bioavailable Quercetin formulation.

Superior absorption

The lecithin utilized in the Phytosome® technology protects quercetin from degradation by water and shuttles the quercetin through the intestinal tract more efficiently. This mimics how taking quercetin with a fatty meal would improve absorption. By using the Phytosome® delivery method, quercetin levels in the blood tested 20 times higher in blood measurements when patients take Quercefit® vs standard quercetin at comparable 500 mg doses. Quercefit® delivers levels of quercetin that one would get from a very quercetin-rich diet.

AUC Improvement

In a recent published study, the Quercefit® Phytosome® formulation was shown to be 20X more absorbable when taken at a 500 mg dose vs. an equivalent dosage of quercetin alone. This greater absorption is key to getting the best effectiveness from quercetin supplementation.

Quercefit®’s superior absorption makes it the quercetin of choice for anyone seeking the many benefits of this powerful flavonol.
