Quercetin Complex

Thorne Quercetin Complex combines quercetin phytosome—quercetin bound to sunflower-sourced phospholipids for enhanced absorption—with bromelain, a pineapple-derived enzyme complex. Together, they support histamine balance, free-radical defense, and a healthy immune response as part of a consistent wellness routine.

Quercetin, one of the two primary ingredients in Thorne's Quercetin Complex, stabilizes the body's mast cells, which store and release histamine, so it supports individuals who suffer from allergies.*

Quercetin appears to have many other beneficial effects on human health, including protection of the gastrointestinal tract and the cardiovascular system, where it scavenges free radicals and inhibits oxidation of LDL cholesterol.*

Thorne's Quercetin Complex combines quercetin phytosome (quercetin bound to sunflower-sourced phospholipids, which increases the body's ability to absorb the quercetin) and bromelain, a compound of protein-digesting enzymes derived from the pineapple plant.* Bromelain also has immune-enhancing properties because it contains constituents that help maintain a healthy cytokine balance.* Bromelain helps reduce bruising and swelling after an injury or surgery.*

A number of quercetin's positive effects appear to be due to its antioxidant activity.* By itself, and paired with vitamin C, quercetin can reduce the incidence of oxidative damage to the skin and nerves caused by the natural depletion of glutathione.*

The advantage of quercetin phytosome is its advanced phytosome technology. Phytosome complexes are created by a patented process that binds a botanical extract to a phospholipid, which are key components of every cell membrane.

Bromelain, which is a mixture of proteolytic (protein-digesting) enzymes from the pineapple plant (Ananas comosus), has been shown to promote healing and reduce temporary and minor swelling and bruising following an injury or a surgical procedure – including dental surgery.* One study of patients with bone fractures found bromelain decreased swelling.*

Bromelain exerts some of its positive effects because of its significant proteolytic activity.* Plastic surgeons have shown interest in bromelain because of its ability to increase the resorption rate of hematomas following surgery.*

Suggested Use:

Take 1 capsule three times daily or as recommended by your health professional.

Warnings:

ALLERGY WARNING

This product is contraindicated in an individual with a history of hypersensitivity to any of its ingredients.

PREGNANCY

INTERACTIONS

Because bromelain has fibrinolytic effects that may potentially inhibit blood clotting, Quercetin Complex should be used with caution or avoided in individuals on anticoagulant therapy.

ADDITIONAL WARNINGS

It is not recommended to remove the Quercetin Complex powder from the capsule to take orally, as it can be irritating to the oral mucosa.

How Thorne Quercetin Complex Fits Your Wellness Routine

• Seasonal and environmental support: Quercetin helps stabilize mast cells that store and release histamine, making it a go-to addition for those looking to support comfort during allergy seasons.
• Antioxidant and cardiovascular defense: Quercetin scavenges free radicals and supports healthy LDL oxidation levels, contributing to everyday cardiovascular and cellular protection.
• Post-activity and recovery support: Bromelain's protein-digesting enzyme complex is commonly used to help reduce bruising and swelling after physical stress, injury, or surgical recovery.
• Immune and cytokine balance: Bromelain contains constituents that support a healthy cytokine balance, complementing quercetin's broad antioxidant activity for a well-rounded immune wellness approach.

Frequently Asked Questions

What makes Thorne Quercetin Complex different from standard quercetin supplements?

Thorne uses quercetin phytosome—quercetin bound to sunflower-sourced phospholipids—which is designed to increase the body's ability to absorb quercetin compared to standard forms. It is also paired with bromelain, a pineapple-derived enzyme complex, for complementary support.

Is Thorne Quercetin Complex a good option for allergy support?

Quercetin is known to help stabilize mast cells, which store and release histamine, making this supplement a popular choice for individuals seeking to support their body during allergy seasons. As with any supplement, it is best used as part of an overall wellness routine.

What is bromelain and why is it included in Quercetin Complex?

Bromelain is a compound of protein-digesting enzymes derived from the pineapple plant. In this formula, it complements quercetin by supporting a healthy cytokine balance and helping to reduce bruising and swelling associated with injury or physical stress.
