Protects cell membranes from oxidative stress

Quercetin has anti-inflammatory, antihistamine and capillary-stabilizing properties, strengthens blood vessels and protects cells from free radicals. It is used to support immunity, treat allergies, cardiovascular diseases and gastrointestinal tract. Quercetin is a powerful natural antioxidant-flavonoid (vitamin P) found in vegetables and fruits. I liked the product from this manufacturer.
