How Much Probiotic Should I Take?
The number of colony-forming-units (CFU), species/strains, and frequency of taking your probiotics should be based on the individual needs and health history of each person. As a general preventive dose, 2 to 10 billion CFU of a mixed strain probiotic is likely a good place to start for children over 1 year of age. There are special probiotics for infants up to 1 year. For adults, 8 to 20 billion CFU is a good daily preventive dose.
Treatment doses and strains, e.g. for post-antibiotic complications, parasitic infections, immune system dysfunction, urinary tract infections and yeast infections (candidiasis), should be determined in consultation with your health care practitioner. Based on an ever-growing body of medical research, your practitioner can also guide you in the use of specific probiotic strains for particular health effects.
