Many things can compromise the immune system:

• Many nutritional deficiencies have been shown to directly impair immune function.
• Air pollution can cause widespread inflammation. While inflammation is a necessary short-term response for eliminating pathogens and initiating healing, chronic inflammation burdens the immune system and makes the body vulnerable for infections.
• Stress and lack of sleep can weaken the immune system by making the body produce excess cortisol, which impairs the immune system.
• A sedentary lifestyle impairs the immune system, but too much strenuous exercise without proper recovery can also expose the body to infections.
• Exposure to environmental UV radiation can also affect the cells responsible for triggering immune responses.
• A diet high in saturated fat impairs the immune system, and excess salt and sugar might also have negative effects. Even a single bout of binge drinking can reduce the immune system’s response capacity. Also tobacco smoke exposure can make the respiratory system vulnerable to live viruses.

Immune system is closely associated with nutritional status. Evidence suggests that with select micronutrients, increased intake can help support and optimize immune function, including resistance to infection.

Rohtos Labs Immune Support Bundle contains two supplements with ingredients that demonstrate immune-supporting and inflammation-suppressing properties. 

• Maintain consists of anti-inflammatory, immune-supporting botanicals in a single easy-to-take formula. The bioactive catechins from green tea are known to exert a broad spectrum of immune-supporting and antiviral activities. Bioactive compounds of broccoli support the immune response. Quercetin possesses anti-inflammatory properties and has been shown to inhibit viral infections.
• Shield is designed to support the production of glutathione within the body and support its metabolism with auxiliary antioxidant compounds such as vitamins C + E and zinc. Glutathione is a master antioxidant that is central to the mechanism by which the body reacts to compounds that cause inflammation. Glutathione can be effectively replenished with supplementation.
• Together, these supplements provide comprehensive immune support based on the joint activity of secondary, exogenous antioxidant compounds and compounds that support the endogenous immune processes within our body.
