NEW: Quercetin Phytosome® Quercefit® - 20x Bioabsorption - 60 Capsules

Why have you changed from traditional quercetin to Quercefit®?

We have upgraded our quercetin formula to Quercefit®, a specialised form of quercetin made using Indena’s Phytosome® delivery technology. Traditional quercetin has notoriously low oral bioavailability, meaning only a small proportion of the amount consumed is absorbed. Quercefit® is designed to improve quercetin bioabsorption by combining quercetin with a phospholipid-based delivery system. Studies report bioabsorption rates up to 20 times that of unformulated quercetin.

Is the new formula stronger than the old formula?

Quercefit® should not be compared directly with conventional quercetin on a milligram-for-milligram basis. It uses Phytosome® technology to improve quercetin absorption, so a lower dose can achieve substantially greater systemic exposure than a larger dose of unformulated quercetin.

In human pharmacokinetic research, a single 250mg dose of Quercefit® produced markedly higher quercetin plasma exposure than 500mg of unformulated quercetin. This is why the formula is built around a 250mg capsule, rather than simply increasing the headline milligram amount. The 250mg format also allows the daily intake to be adjusted flexibly according to the recommended serving.

What does Phytosome® mean?

Phytosome® is Indena's food-grade delivery technology for botanical compounds with naturally limited oral bioavailability. The technology associates botanical constituents with phospholipids, helping improve characteristics such as dispersion, solubility and absorption. In Quercefit®, this technology is used specifically to improve the bioabsorption of quercetin. You can read more here.
