The immune system is responsible for defending the human body against harmful microorganisms that cause illness and disease. Without the immune system, the human body would be exposed to these microorganisms that cause illness and diseases. Even with the presence of the immune system, a weak immune system cannot defend the body from disease and illness. The weaker the immune system, the greater the chances of falling sick. Therefore, it is of utmost importance that we maintain a strong immune system all year round, especially during the cold, flu and allergy seasons.

With all the work the immune system does, chances are the immune system can become weakened, but the good news is that you can support your immune system through proper nutrition and supplementation. While it's always ideal to get important nutrients from food, some vitamins can be difficult to get enough of from diet alone. So, which supplements are really the best for immune system boosting?
