Natural ways to strengthen the immune system include: 1. Keep blood levels of Vitamin D between 50-70 ng/ml.
2. Avoid sugar, especially while sick as it weakens the immune system.
3. Sleep as much as possible.
4. Manage stress levels with prayer, meditation, yoga, bubble baths, or anything else that works!
6. Take Omega-3 fatty acids.
7. Wash hands frequently, but avoid antibacterial products
. 8. Avoid hospitals.
I would also add anything that is not processed or altered chemically!
