Promotes a Healthy Immune Response
EnviroDefender* includes ingredients shown in research to help support balanced immune activity.* Boswellia helps block the 5-LOX pathway, a key driver of immune overreactions (Safayhi et al).* Bromelain influences white blood cell signaling between the innate and adaptive immune systems, helping support a healthy immune response (Secor et al).*
Helps Put the Brakes on Histamine
EnviroDefender* features ingredients that work across the histamine cycle—its production, release, and breakdown.*
Grapeseed extract helps inhibit histidine decarboxylase, the enzyme that produces histamine.*
Quercetin may slow histamine release and has been shown to support eye comfort in human studies (Remberg; Hirano; Shishehbor).*
Nettles may help stabilize mast cells and support nasal comfort (Thornhill; Kelly; Roschek; Mittman).*
Vitamin C helps break down histamine that has already been released and bioflavonoids may enhance its activity (Marcin; Sampson).*
Supports & Regulates the Immune System
Vitamin D and zinc both play essential roles in immune regulation.* Vitamin D supports both innate and adaptive immune cells and helps modulate cytokines (Tian; Cheng).* Zinc influences T-helper cell gene expression (Prasad).* A 2016 review of 62 studies found that low levels of zinc and vitamin D were associated with greater seasonal discomfort in children (Nur-matov et al).*
