Quercetin is a natural flavonoid that supports heart and immune system health . It has anti-inflammatory properties that can improve cardiovascular health . Quercetin also supports skin health . Important for the prevention of allergic reactions and the immune system .
Quercetin belongs to a class of compounds called polyphenols. It can be found in various fruits , vegetables , grains and herbs . Foods rich in quercetin include onions , apples , berries , citrus fruits , broccoli , cabbage and green tea . Quercetin itself has relatively low bioavailability, meaning that a significant portion of the quercetin consumed may not be effectively absorbed by the body. Concomitant administration of quercetin with certain substances , such as bromelain , may increase its absorption and bioavailability .
Quercetin is known for its ability to promote a healthy inflammatory response in the body by inhibiting certain enzymes and signaling pathways associated with inflammation. Additionally, the antioxidant properties of quercetin contribute to its potential to reduce oxidative damage and promote a healthy aging process. Quercetin also supports cardiovascular health and proper blood vessel function.
Due to new research, quercetin has recently become very popular for its potential to alleviate allergies and provide relief to individuals with allergic conditions. This is due to the reduction of histamine , a compound that plays a central role in allergic reactions. An allergy involves an inflammatory response caused by an exaggerated response of the immune system to harmless substances.
Quercetin can also inhibit the activation of mast cells and thereby potentially reduce the release of inflammatory compounds and associated adverse allergic reactions.
One of the interesting aspects of quercetin is its ability to interact with zinc ions. Quercetin can act as a zinc ionophore , allowing zinc to be transported into cells . This interaction greatly increases the availability of zinc in the body, which plays a key role in immune function , cell growth and DNA synthesis . By supporting optimal zinc levels, quercetin can have a positive effect on immunity and overall well-being. Quercetin can also synergistically benefit from combinations with other compounds , increasing its potential benefits . For example, combinations such as quercetin with pycnogenol , quercetin with green tea , quercetin with black cumin seed oil , quercetin with bromelain and zinc , with curcumin , with resveratrol , vitamin C, omega-3 fatty acids and vitamin D3 offer potential synergistic effects for many areas .
