What exactly is Quercetin?
A defined flavonol extracted from a named botanical source.
Quercetin is a naturally occurring plant compound classified as a flavonol. The Crown Supplements formula supplies it as a concentrated extract with a declared 98% Quercetin specification.
The botanical source is identified as Sophora japonica, a name widely used for the Japanese pagoda tree. The currently accepted botanical name is Styphnolobium japonicum, while Sophora japonica remains a familiar synonym used across ingredient and product descriptions.
Each capsule contains 173mg of the 98% extract. Two capsules provide 346mg of extract and represent 339.08mg of Quercetin at the declared specification.
The defined plant compound
Quercetin is the named flavonol that accounts for 98% of the stated extract specification.

The botanical source name
Sophora japonica is the familiar botanical synonym used within the product and ingredient name.

Why choose these Quercetin Sophora Japonica Extract capsules?
The 98% extract should lead the formula.
British shoppers buying Quercetin capsules are paying for the Quercetin extract. Crown Supplements keeps the formula centred on the defined 98% Sophora Japonica extract rather than filling capsule space with materials added for bulk, binding or machinery convenience.
Defined Quercetin extract
The formula identifies Quercetin as the core plant compound inside the capsules.
98% specification
The Quercetin percentage is stated directly rather than hidden behind general plant wording.
Named botanical source
Sophora japonica is identified within the full ingredient description.
346mg serving
Two capsules provide 346mg of the defined botanical extract.
HPMC capsule shell
The 98% extract is enclosed inside HPMC hypromellose capsule shells.
No production clutter
No fillers, binders or machine flow agents are added by Crown Supplements.
The Crown Supplements formula standard
Built around Quercetin—not machinery convenience.
When botanical capsule formulas include fillers, binders, bulking materials or flow agents, part of the ingredient list is built around production rather than the Quercetin extract printed on the front.
They may help the machine. They are not the reason the customer buys the capsule.

Customers across Great Britain can choose 90, 180, 270 or 360 capsules. At two capsules taken twice per day, four capsules provide two complete servings and 692mg of extract across the recommended day.
