Supplements can help to support immune system functions by reducing inflammation and increasing immune cells that fight viral infections. Some key supplements include vitamins C, D, and the B family, zinc, magnesium, glutathione, and astragalus.

Getting enough sleep is crucial for keeping your immune system strong and reducing the risk of getting sick. Improve your sleep hygiene by having a consistent bedtime routine, limiting caffeine and alcohol, exercising, and taking calming supplements.
