Quercetin is a naturally occurring flavonoid found in onions, apples, and capers.

It’s known for its antioxidant properties and is commonly included in wellness routines that focus on seasonal changes, immune system awareness, or recovery from high-demand environments.

This formula uses Quercefit®, a clinically studied, high-bioavailability form of quercetin made using Phytosome™ delivery technology.

It’s designed to support better absorption compared to standard quercetin, and is delivered in a clean, vegan capsule with no unnecessary ingredients.

For persons over 18 years:
Take 1 to 2 capsules per day with food or as recommended by your healthcare professional.

Quercetin-phospholipid complex [Quercetin (Styphnolobium japonicum L. Schott), sunflower lecithin], capsule shell (hydroxypropyl methylcellulose), microcrystalline cellulose, magnesium stearate, silica.

Store in a cool, dry place below 25°C. Protect from light and moisture.

Quercefit® is made using Phytosome™ technology to improve quercetin’s solubility and bioavailability.

The formula is manufactured under GMP conditions and independently tested for quality and consistency.

COMPLEMENTARY PRODUCTS

Quercetin Bioactive is a natural flavonoid supplement that supports immune health, inflammation regulation, and histamine balance.

It’s commonly used for allergy relief, respiratory support, and antioxidant protection, especially during times of seasonal or environmental stress.

This formula uses Quercefit®, a patented quercetin bound to Phytosome™ delivery technology, enhancing absorption by up to 20 times compared to standard quercetin.

This means more active compounds reach your bloodstream, where they can provide fast and effective support.

Take one capsule daily with food.

During high-allergy seasons or immune challenges, some people take two per day—morning and evening.

For long-term antioxidant support, consistent daily use is most effective.

Yes. Quercetin is generally well tolerated, but it may interact with certain medications, especially antibiotics or blood thinners.

If you’re on prescription medication, consult your healthcare provider.

Mild digestive upset may occur in very sensitive individuals.

Absolutely. Quercetin is commonly used both year-round and seasonally to support immune modulation, oxidative stress reduction, and cellular resilience.

Long-term use is considered safe at recommended doses.

Yes. In fact, quercetin often works synergistically with vitamin C and zinc, enhancing immune and antioxidant activity.

This makes it a popular part of natural immune protocols during cold and allergy seasons.
