Quercetin 300
This formulation incorporates the highest potency quercetin available, derived from a non-citrus, hypoallergenic plant source, and stabilized with additional antioxidants so as not to auto-oxidize (degrade spontaneously). Quercetin has been shown to support the integrity of mast cells, which play a key role in controlling the release of histamine.* In addition, Quercetin has been shown to reduce the production of prostaglandins and leukotrienes.*
Suggested Use: As a dietary supplement, 1 or 2 capsules one to three times daily with meals, or as directed by a health practitioner.
