For powerful, year-round respiratory and immune system support, count on Solaray. An ideal supplement during seasonal changes, quercetin may be beneficial to the respiratory system by supporting the bodys modulation and release of histamine.

In Solaray Mega Quercetin, we combine it with two other powerful bioflavonoids rutin and hesperidin. Responsible for the bright pigments in fruits and vegetables, bioflavonoids may help support antioxidant processes in the body for healthy immune system function, sinus, circulation and respiratory health. Our potent formula also includes bromelain “ a plant enzyme known to help breakdown protein" and vitamin C, intended to help support healthy immune function, collagen synthesis, capillary and blood vessel integrity, and more.

Mega Quercetin 600 mg is vegan, and like all Solaray products, is lab verified for potency and purity. Confidence in the Solaray name is just one of the reasons we've been around so long and maintain our place as a leader in the industry. Unlike many other companies, we manufacture almost all our own products, which gives us the ability to thoroughly test and screen raw ingredients for the slightest amount of impurities and manage the production process to provide the best possible quality.

Rest assured, only the purest formulas ever reach your cabinet. And because we are always committed to leaving the world a little better than we found it, we now package our products in 100% post consumer recycled plastic bottles. Count on Solaray Mega Quercetin 600 mg for the quality difference you can feel.
