Product Informations
Quercetin is a flavonoid, a type of plant pigment that is widely distributed in nature. It is found in various fruits, vegetables, grains, and herbs. 

Natural Sources: Quercetin is abundant in many plant-based foods. It is found in fruits such as apples, berries, grapes, and citrus fruits. Vegetables like onions, kale, broccoli, and tomatoes also contain quercetin. Other sources include tea, red wine, cocoa, and various herbs, including ginkgo biloba, St. John's wort, and green tea.

Antioxidant Properties: Quercetin is known for its potent antioxidant activity. It can scavenge and neutralize free radicals, which are highly reactive molecules that can cause damage to cells and tissues. By combating oxidative stress, quercetin helps protect the body against various diseases and supports overall health.

Anti-Inflammatory Effects: Quercetin has been studied for its anti-inflammatory properties. It may help reduce inflammation by inhibiting the production and activity of inflammatory mediators, such as cytokines and enzymes like cyclooxygenase (COX) and lipoxygenase (LOX). 

Bioavailability and Supplementation: Quercetin's bioavailability can be relatively low when consumed through dietary sources alone. However, certain formulations or combinations with other compounds (e.g., bromelain) may enhance its absorption. Quercetin supplements are available in various forms, including capsules, tablets, and powders, and are often used to achieve higher doses than what can be obtained from food alone.
