OrthoMune is a physician-formulated immune support supplement that targets multiple pathways of the immune response simultaneously — providing both the foundational micronutrients needed for baseline immune function and the specialized botanicals and cofactors that mount a rapid, effective response to acute immune challenges. Designed for year-round immune support and acute use during periods of increased immune demand.Vitamin C (as Ascorbic Acid and Calcium Ascorbate) at clinically meaningful doses supports the proliferation and activity of lymphocytes, neutrophils, and natural killer cells, and is a primary antioxidant defense against free radical damage during immune activation. Vitamin D3 (Cholecalciferol) modulates the innate and adaptive immune response through Vitamin D receptors expressed on virtually every immune cell — deficiency is strongly associated with impaired immune function and increased susceptibility to infections. Zinc (as TRAACS® Zinc Bisglycinate) supports T-cell development, cytokine regulation, and acts as a direct antiviral agent. Quercetin (as Quercetin Phytosome®) acts as a zinc ionophore — facilitating zinc's entry into cells — while independently providing potent anti-inflammatory and antiviral activity. N-Acetyl Cysteine (NAC) replenishes glutathione, the primary antioxidant defense during immune activation, and directly disrupts viral replication mechanisms. Elderberry Extract provides antiviral flavonoids shown to inhibit viral attachment and reduce symptom duration.120-capsule supply. Gluten-free, GMP certified.
