I'd suggest that you try to get as many probio lite in your system as possible, this way, you will be able to keep your immune system in tip top shape. The colds that other people get won't really harm you, because you will be able to fight them off. Additionally, with a strong defense against colds, you'll notice a lack of eczema if you happen to have that as well. https://walkinghealth.org/probio-lite/
