Highly Absorbable Quercetin for Immune, Antioxidant & Healthy Ageing Support
Thorne Quercetin Phytosome provides an advanced, highly bioavailable form of quercetin designed to overcome the naturally poor absorption of standard quercetin supplements.
Quercetin is a naturally occurring plant flavonoid found in foods such as onions, apples, berries, grapes and leafy green vegetables. It is well known for its antioxidant activity and its ability to support healthy immune function, a balanced inflammatory response and healthy histamine release.
What makes Thorne Quercetin Phytosome different is its use of phytosome technology. Quercetin is bound to sunflower-derived phospholipids, helping it pass more efficiently through the intestinal barrier. Research on this delivery system has demonstrated up to 20 times greater blood levels of quercetin compared with unbound quercetin, allowing effective nutritional support from a relatively small capsule.
Key Benefits
- Supports healthy immune system function
- Helps maintain a balanced seasonal immune response
- Supports healthy histamine release and mast-cell function
- Provides powerful antioxidant protection against free radicals
- Supports a healthy inflammatory response
- Helps support respiratory tract health
- Supports healthy cellular ageing
- Provides quercetin in a highly absorbable phytosome form
- Uses sunflower-derived phospholipids
- Gluten free, dairy free and soy free
Although quercetin occurs naturally in many healthy foods, conventional supplemental quercetin has one significant limitation – it is poorly absorbed by the body.
Thorne addresses this problem using advanced Phytosome® technology.
A phytosome combines a botanical compound with phospholipids – natural components similar to those found in cell membranes. In Thorne Quercetin Phytosome, quercetin is complexed with sunflower-derived phospholipids, creating a form that can cross the intestinal barrier more efficiently.
This enhanced delivery system has been shown to provide up to 20 times greater bioavailability than standard unbound quercetin.
This means you can obtain the benefits of quercetin without relying on the very large doses commonly found in conventional quercetin products.
Immune & Seasonal Support
Quercetin has been extensively studied for its role in immune health.
It helps support a balanced immune response and healthy function of several types of immune cells. Quercetin is also particularly interesting for people seeking nutritional support during times of seasonal environmental sensitivity.
Quercetin can help support the stability of mast cells – immune cells involved in the storage and release of histamine – helping the body maintain a healthy and balanced histamine response.
For this reason, quercetin is commonly included in nutritional protocols focused on seasonal wellness, respiratory health and immune balance.
Powerful Antioxidant Protection
Quercetin belongs to a family of plant compounds called flavonoids.
Flavonoids act as antioxidants, helping neutralise free radicals generated by normal metabolism and everyday environmental exposure.
Excess oxidative stress can affect cellular structures and contribute to the normal ageing process. Quercetin provides nutritional antioxidant support to help protect cells from oxidative stress while supporting overall cellular health.
Supports a Healthy Inflammatory Response
A normal inflammatory response is an important part of the body's natural defence and recovery processes.
Quercetin helps support healthy inflammatory signalling and may be particularly useful for individuals looking to support immune, respiratory and general cellular health.
Its combination of antioxidant and inflammatory-response support also makes quercetin popular among active individuals and people focused on long-term wellness.
Quercetin & Healthy Ageing
Quercetin has attracted growing scientific interest in the field of healthy ageing and cellular longevity.
Research has investigated quercetin's potential role in cellular processes associated with ageing, including cellular senescence and sirtuin activity.
Senescent cells are ageing or dysfunctional cells that have stopped dividing but can remain within tissues. Their accumulation is one of the processes researchers are studying in relation to biological ageing.
Combined with quercetin's well-established antioxidant properties, these emerging areas of research make quercetin an increasingly popular nutrient for people interested in healthy ageing and long-term cellular wellbeing.

What is Thorne Quercetin Phytosome?
Thorne Quercetin Phytosome is a highly absorbable form of quercetin, a naturally occurring plant flavonoid with antioxidant properties. Quercetin supports healthy immune function, a balanced inflammatory response, healthy histamine release, respiratory health and healthy ageing.
Unlike standard quercetin supplements, Thorne uses phytosome technology to improve absorption.
What is special about Quercetin Phytosome?
Standard quercetin is naturally difficult for the body to absorb. Quercetin Phytosome combines quercetin with sunflower-derived phospholipids to help it pass more efficiently through the intestinal barrier.
Research on this phytosome form has demonstrated up to 20 times greater blood levels of quercetin compared with unbound quercetin.
Why does each capsule contain only 250 mg of Quercetin Phytosome?
More milligrams do not necessarily mean better absorption.
Standard quercetin is poorly absorbed, which is why conventional products often contain 500 mg, 1,000 mg or more per serving. Thorne uses an enhanced phytosome delivery system designed to substantially improve quercetin bioavailability.
Each capsule provides 250 mg of Quercetin Phytosome, a phospholipid complex derived from sunflower.
What is a phytosome?
A phytosome is a delivery system in which a plant compound is combined with phospholipids – components similar to those naturally found in cell membranes.
This helps certain botanical compounds that are normally difficult to absorb cross the intestinal barrier more efficiently.
In Thorne Quercetin Phytosome, the phospholipids are sourced from sunflower.
Can quercetin help support a healthy histamine response?
Yes. Quercetin is commonly used nutritionally to support a healthy histamine response.
Quercetin helps stabilise mast cells – immune cells that store and release histamine – and supports the normal regulation of histamine release.
For this reason, quercetin is frequently used as part of nutritional support for people wanting to maintain seasonal, respiratory and histamine balance.
Is Quercetin Phytosome suitable for seasonal support?
Yes. Quercetin is particularly popular during times of seasonal environmental exposure because it supports healthy immune function, mast-cell stability and normal histamine release.
Thorne specifically recommends Quercetin Phytosome for supporting healthy seasonal immune system function.
Does Thorne Quercetin Phytosome contain bromelain?
No. Thorne Quercetin Phytosome does not contain bromelain.
It contains Quercetin Phytosome as its active ingredient.
Customers looking for a Thorne formula that combines quercetin with bromelain may wish to consider Thorne Quercetin Complex, which is a different product.

What foods naturally contain quercetin?
Quercetin occurs naturally in many plant foods, including:
- Onions
- Apples
- Berries
- Grapes
- Leafy green vegetables
Onions are particularly rich dietary sources of quercetin.
Is Quercetin Phytosome an antioxidant?
Yes. Quercetin is a flavonoid with significant antioxidant activity. It helps protect cells against oxidative stress caused by free radicals and supports normal cellular function and healthy ageing.
Does quercetin support healthy ageing?
Quercetin is increasingly being researched for its potential role in healthy ageing and cellular health.
In addition to its antioxidant activity, researchers are studying quercetin in relation to cellular senescence – the accumulation of ageing or dysfunctional cells.
For customers interested in longevity, it can therefore provide nutritional support as part of a broader healthy lifestyle rather than being viewed as a treatment for ageing.
What is the difference between Thorne Quercetin Phytosome and regular quercetin?
The main difference is absorption.
Regular quercetin is poorly absorbed by the gastrointestinal tract. Thorne combines quercetin with sunflower phospholipids using phytosome technology, which can significantly increase the amount of quercetin that reaches the bloodstream.
This means comparing quercetin products based only on the number of milligrams on the label can be misleading. A larger dose of conventional quercetin does not necessarily provide greater absorbed quercetin than a smaller amount delivered using an enhanced absorption system.
