Boost your immune system with the enhanced, plant-based antioxidant power of quercetin.

Quercetin is a flavonoid, a plant pigment found in fruits and vegetables like apples, onions, berries, and tea. Flavonoids act as antioxidants, neutralizing harmful free radicals caused by daily oxidative stress. Free radicals can lead to cellular damage, premature aging, and chronic health issues.

Thorne’s Quercetin Phytosome delivers the antioxidant and immune-boosting benefits of quercetin while Aiding a healthy inflammatory response. Quercetin typically has low bioavailability, but Thorne’s phytosome technology significantly increases absorption—making Quercetin Phytosome up to 20 times more bioavailable than standard quercetin extracts.

Who Benefits from Quercetin Phytosome:

• Those seeking to enhance immune function  
• Individuals dealing with seasonal allergies or hives  
• Those wanting to Aid respiratory health and recovery  
• Biohackers aiming to optimize sirtuin function and reduce senescent cells  
• Anyone interested in healthy aging  

Immune and Allergy Support:

Quercetin Phytosome provides robust immune Aid, offering relief for allergy sufferers and promoting respiratory health. 

• Enhances immune cell function for an optimized immune response  
• Regulates histamine release to aid allergy management 
• Supports a normal inflammatory response, especially in the respiratory tract  

Unique Benefits for Healthy Aging:

Recent research highlights quercetin’s role in healthy aging by reducing cellular senescence—damaged cells that stop dividing but don’t die, contributing to aging and age-related issues. Quercetin is one of the few nutrients shown to decrease these cells. It also:

Activates sirtuins, which regulate cellular health and Aid metabolic functions  

Combines antioxidant, sirtuin, and senescence benefits to promote healthy aging at the cellular level
