Origin & History
Isoquercitrin is a potent flavonoid glycoside, a bioactive compound abundantly found in elderflowers (Sambucus nigra), as well as in apples, onions, and berries. While elderflowers are native to Europe, North Africa, and parts of Asia, isoquercitrin itself is a ubiquitous plant metabolite. It is highly valued in functional nutrition for its strong antioxidant, anti-inflammatory, and immune-supporting properties.
“While elderflowers have a rich history in European traditional medicine for immune and respiratory support, isoquercitrin itself is a modern biochemical compound. Its identification and study as a key bioactive in elderflowers and other plants have propelled its use in contemporary health and wellness formulations.”Traditional Medicine

Frequently Asked Questions
What is Isoquercitrin?
Isoquercitrin is a powerful antioxidant compound called a flavonoid, found naturally in foods like elderflowers, apples, and onions. It is known for its ability to help manage allergy symptoms and reduce inflammation throughout the body.
How much Isoquercitrin should I take for allergies?
Clinical studies suggest a dosage of 200-500 mg per day for supporting the body's response to seasonal allergies. It's best to start at a lower dose and take it with food for optimal absorption.
Is Isoquercitrin better than Quercetin?
Isoquercitrin is a form of quercetin that is attached to a sugar molecule, which makes it much easier for the body to absorb. Studies show it has significantly higher bioavailability, meaning you get more of the active compound into your system compared to standard quercetin supplements.
