I have a very poor immune system i try to take a lot of vitamins but it doesn't seem to help, what can help my immune system grow strong?

Dr. John Chiu answered

No: Vitamins usually are not associated with much side effects and aside from possibly vitamin d3 do not do much for the immune system. Assuming that you are not deficient in any of the vitamins. Aerobic exercise may improve your immune system somewhat but if you have frequent sinus or lung infections, consult an allergist/immunologist.
