THORNE Quercetin Phytosome Supplement — 60 Capsules, Enhanced Absorption Phospholipid Complex for Immune & Respiratory Support

THORNE Quercetin Phytosome is a highly absorbable quercetin supplement in a phytosome delivery system formulated to support immune response, respiratory comfort, and cellular antioxidant defenses.*

Quercetin is a plant-based flavonoid found in many fruits and vegetables. THORNE’s Quercetin Phytosome combines quercetin with a phospholipid complex to enhance absorption compared with standard quercetin powders. Each bottle contains 60 capsules intended for regular use as part of a wellness regimen; the formulation targets bioavailability so smaller, consistent doses deliver more usable compound to cells.

How does the phytosome form improve quercetin absorption?

The phytosome process binds quercetin to phospholipids, which increases compatibility with cell membranes and supports better uptake in the digestive tract. Improved absorption can help the body utilize the compound more efficiently than non-complexed quercetin powders.

• Phospholipid complex enhances membrane passage
• Smaller doses can be more effective due to better uptake
• Designed for consistent daily supplementation

Can this product support seasonal or respiratory wellness?

THORNE Quercetin Phytosome is formulated to support healthy inflammatory balance in the respiratory tract and to help regulate histamine release, which may benefit people during seasonal changes. The product is intended as a nutritional support, not a treatment for conditions.

• Promotes healthy respiratory inflammatory responses*
• Supports balanced histamine activity for seasonal sensitivity*
• Formulated for year-round supplemental use

What role does this supplement play in antioxidant and cellular support?

Quercetin is a naturally occurring antioxidant that helps cells manage oxidative stress. THORNE’s formulation aims to provide cellular-level support for healthy aging and overall cellular health when used alongside a balanced diet and lifestyle.

• Provides antioxidant support to mitigate oxidative stress*
• Supports cellular resilience and long-term wellness goals*
• Suitable for daily use to complement nutrition and lifestyle

How should I incorporate THORNE Quercetin Phytosome into my routine?

Follow the suggested use on the product label or your practitioner’s guidance for dosing and timing. Consistent daily intake typically achieves the best maintenance effects because the product is formulated for steady bioavailability rather than large intermittent doses.

• Take as directed on the label or by a healthcare professional
• Works well alongside a nutrient-rich diet and lifestyle
• Store in a cool, dry place to preserve potency
