If i take probiotic supplements, will it help get rid of my cold faster?

Not likely but...: Some probiotics can boost immune function a bit but taking these probably won't have much effect on getting rid of a cold (though might help to prevent them!). The best way i know to get rid of a cold is pelargonium sidoides, widely available at health food stores & some pharmacies as umcka, a herb from South Africa proven to effectively treat colds, coughs & sinus infections.
