2. Take a probiotic every day
I have taken probiotics daily for years. In addition to improving digestion and intestinal health, they boost your immunity and can protect you from colds and flu. A 2009 study published in the journal Pediatrics reported that children who took a probiotic daily for six months decreased their incidence of viral infections, shortened the duration of infections they got and decreased the need for antibiotic prescriptions. Ask your pharmacist or family doctor for a recommendation if you aren’t sure which one is right for you. And follow the recommended dosage on the label.
