thA healthy immune system requires essential vitamins and nutrients, but many people don’t hit this goal.  So if you tend to fall short, using supplements to boost the immune system can help compensate.

Your immune system protects your body from diseases and viruses that you encounter each day. A weakened immune system hinders your ability to ward off those foreign substances. With a weakened immune system, you will get sick more often. Besides that, you might experience worse symptoms than you would with a strong immune system.

Replenishing your vitamins and nutrients each day is essential to boosting and maintaining immune health. You can’t eat healthy one day or take one supplement and expect to experience the benefits. Work on implementing a regular healthy dietary routine, and then you can add immune system supplements to your eating plan.

1. Vitamin C

Vitamin C can help prevent infection and help you overcome illness quicker. You should consume between 75 and 90 mg of this vitamin each day. Vitamin C contains antioxidants that help reduce inflammation, preventing respiratory distress.
