Hey, greetings from slovenia. i'd love to know what's the best, the fastest, the most affective natural or anything thing to boost my immune system?

Not proven effective: Many "non-medical" supplements, foods, herbs, and techniques are claimed to "boost" the immune system, but none have been proven effective. The immune system is complex, and "boosting" it to make it act stronger is not always a good thing. In conditions like arthritis, thyroid disease, diabetes type 1, lupus, eczema, etc..., the immune system is over-acting and damaging the patient's own organs.
