NuMedica® Seasonal Shield® is an advanced, broad-spectrum nutritional formula designed to support your body's natural defenses during times of seasonal environmental challenges.* Featuring a synergistic blend of Vitamin C, Vitamin D3, Zinc, Quercetin, Bromelain, Nettle Extract, and N-Acetyl L-Cysteine (NAC), this formula helps maintain healthy immune function, support balanced histamine levels, and promote clear airways and normal mucus viscosity.*
The foundation of Seasonal Shield® rests on three key immune-supporting nutrients: Vitamin C, Vitamin D3, and Zinc. Together, they strengthen immune defenses, provide antioxidant protection, and support healthy inflammatory responses.*
Seasonal Shield® goes beyond basic vitamins and minerals. It includes Quercetin, Bromelain, and Nettle Extract, a combination known to support balanced histamine levels and healthy mucus viscosity-two key factors in seasonal comfort.*
Additionally, N-Acetyl L-Cysteine (NAC) helps maintain healthy levels of glutathione (GSH)-the body's master antioxidant-further supporting respiratory and immune health.*
When the seasons change, environmental factors like pollen, mold, animal dander, and dust can trigger immune responses that lead to discomfort. Seasonal Shield® is formulated to address these challenges by supporting your body's natural defenses, promoting clear airways, and helping maintain comfort during seasonal transitions.* For additional strategies on managing seasonal changes, explore our article on Seasonal Allergies - Understanding and Managing Your Symptoms.

Seasonal Shield® is designed to support the body's natural defenses during seasonal environmental changes. It combines vitamins, minerals, and phytonutrients that work synergistically to promote immune balance, clear airways, and histamine support when pollen, mold, or other irritants are at their peak.*
Unlike many over-the-counter allergy products that focus only on symptom relief, Seasonal Shield® provides a comprehensive nutritional foundation. It includes Vitamin C, Vitamin D3, and Zinc for immune support, plus Quercetin, Bromelain, Nettle Extract, and NAC to promote healthy histamine levels, mucus viscosity, and respiratory comfort.*
Seasonal Shield® is formulated to stand alone as a broad-spectrum seasonal support formula, but many people use it alongside other targeted immune products for additional support. Always consult your healthcare practitioner when combining supplements, especially if you use prescription medications or have chronic health conditions.*
For best results, begin taking Seasonal Shield® 2-4 weeks before the start of your typical allergy season. This gives your body time to build up nutrient levels and prepare its natural defenses. Daily use throughout the season supports consistent immune balance and respiratory comfort.*
