5 Effective Immune System Nutrients


1. Zinc is an essential trace mineral that supports the immune system, helps with wound healing, and acts as a powerful antioxidant. Some signs that you could be deficient in zinc are: frequent colds, poor concentration, slow wound healing, and fatigue.

2. Quercetin is a bioflavonoid antioxidant which helps to scavenge or get rid of free radicals. It also has anti-viral properties. 3. Vitamin C is an essential water-soluble vitamin which helps fight infections and viruses. 4. NAC (N-acetyl-cysteine) helps the body clear mucus. It is also the precursor to glutathione which is a strong antioxidant that helps the body detoxify.


5. Vitamin D is a fat-soluble vitamin that helps the immune system function optimally. If you are wondering how much vitamin D to take, it’s best to have your values checked.
