Great question! Many people have opinions about "how" to boost the immune system. Practically speaking, there is no correct answer to this. The immune system is very complex and I am not aware of anything in particular that will globally "boost" this. A good diet, regular exercise, and an appropriate amount of sleep are good things along with the things that you are doing.
No magic pill. Many people are looking for some "magic pill" to "boost their immune system". There is no such pill. However, there is a way to boost your immune system, live a healthy lifestyle. Proper diet, proper sleep- wake cycles, healthy environment, proper exercise are the foundation of good health and good immune health. Supplements should be used selectively to supplement a healthy diet.
