We still have several months of cold and flu season to weather. Protecting our immunity is vital during this season and the attack on our immune cells. Thankfully, our bodies have built-in immune complexes that go to work in our defense at the first sign of threat. However, we need to nourish those complexes so they work as they should and certainly not live in such a way that we weaken them. They have a difficult job because there are so many agents coming against our immunity in the way of chemicals, allergens, and toxins. In order to stay your healthiest, learn about key nutrients found in foods and supplements that can enhance your immune system and keep you feeling your best.
