What is quercetin?

Quercetin is a natural compound found in foods such as onions, apples, and berries. It belongs to the category of phytonutrients (plant-derived compounds) and specifically to the flavonoid family. These compounds give colour to vegetables and fruit, and in the plant itself play a role in protection against environmental stress, such as UV radiation and pathogens.

European legislation protects consumers by setting strict rules for health claims. Because there are currently no approved EFSA claims for quercetin, we can only share factual product information, not health benefits.

Quercetin as a supplement

Quercetin is widely used around the world as a dietary supplement. The compound appeals to people who are mindful of their diet and take the quality of their supplements seriously.

It is a compound that is not obtained in large amounts through diet, even with a healthy eating pattern. That makes supplementation a logical addition for many people, especially during periods when they pay extra attention to their intake.

Through a typical Western diet, average daily quercetin intake ranges between 10 and 30 mg. Those who eat plenty and a wide variety of vegetables and fruit will get more, but the compound is unevenly distributed in food and difficult to dose through meals alone.

Quercetin is not a medicine. It is a dietary supplement that falls within the flavonoid category, alongside other plant-based polyphenols such as resveratrol and EGCG from green tea.

Why liposomal?

Quercetin is naturally poorly soluble in water. This has a practical consequence: the gastrointestinal tract absorbs regular quercetin only to a limited extent. A large proportion of a standard quercetin capsule or tablet passes through the body without being fully absorbed.

In liposomal quercetin, the active compound is enclosed in liposomes: microscopically small spheres made up of phospholipids, the same building blocks found in your own cell membranes. This structure protects the quercetin from breakdown by stomach acid and makes it easier for the compound to pass through the intestinal wall.

The result is a higher bioavailability compared with regular quercetin in powder or tablet form.

Who is liposomal quercetin for?

This supplement is developed for people who consciously choose a high-quality form of quercetin, where absorption is central rather than just the dosage on the label.

Liposomal quercetin is often chosen by:

• People who already have experience with quercetin supplements and are looking for a better-absorbed form
• People with limited variety in their vegetable and fruit intake who want to supplement their flavonoid intake
• Athletes and people with an active lifestyle who are mindful of their supplement use
• People looking for a pure, plant-based supplement, free of animal-derived ingredients

Quercetin is not a substitute for a varied diet, but a complement to it. It is a dietary supplement and no medical claims are made in connection with it.
