• Broad-Spectrum Support for Healthy Immune Function
• Support Healthy Respiratory Function
• Maintains Normal Inflammatory Balance

Shield is a targeted blend of nutrients designed to provide a broad-spectrum support to the body’s immune reserves. The formula includes quercetin, a powerful bioflavonoid that aids in supporting the immune system. Vitamin C and N-acetyl cysteine are potent antioxidants that promote respiratory function and support the function of quercetin. Vitamin D and zinc are important micronutrients needed to create a robust immune reserve. This powerful combination works to promote healthy respiratory and immune function.

Quercetin

Quercetin is best known for its antioxidant activity in scavenging free radicals. Additionally, quercetin helps balance cytokine levels and improve T-lymphocyte balance.

N-Acetyl Cysteine

N-acetyl cysteine (NAC) is the precursor of the master antioxidant, glutathione. NAC has been shown to support mucus clearance and normal respiratory function, through its ability to cleave disulfide bonds in mucus.

Immune Nutrition Base

Shield contains the synergistic nutrient blend of zinc, vitamin C, and vitamin D, which each play a major role in maintaining immune system reserves.
