Keeping the immune system supported every day, not just during cold and flu season, can help protect the body against future colds. To do that, Schwartz suggests sleeping eight hours each night, staying hydrated, moving your body regularly, and eating a diet high in lean proteins, healthy fats, and veggies. You can also consider immune-essential targeted nutrients and bioactives like vitamin C, vitamin D, zinc, lactoferrin, and probiotics.
