When you ask a doctor, "What is the most important function in our body?" They will tell you that your immune system is the thing to keep strong. Our immune system is supported by our blood, lymph nodes, and gut. Supplements high in antioxidants are a must, but also a good diet, exercise, and getting enough sleep are important in supporting your immune system.
The immune system is a complex network of cells and proteins that defends the body against infection. The immune system keeps a record of every germ (microbe) it has ever defeated so it can recognize and destroy the microbe quickly if it enters the body again.
By using plants and minerals to support your immune system, your body is able to recognize them, and how to use them best to support the body! This contributes to increased energy by keeping your immune system 'high' and out of the constant cycle of fighting off/recovery from illness after illness! If you get sick more than three times a year, you need to make some lifestyle changes to support your immune system. Period!
