In most cases, it's fine to enjoy probiotic drinks daily. However, you should keep in mind that probiotics are not a cure or medical treatment for any serious health condition. If you're dealing with serious digestive issues, persistent yeast infections, or another problem that may be improved upon with probiotics, you should speak with your doctor. A healthcare professional can help you determine whether probiotics might help and if there's any reason to be concerned about drinking probiotic beverages too often. If you're in good health, a daily probiotic drink may help you maintain your health. Some people have loose stools the first day or two when they start enjoying probiotic drinks, but this will usually resolve quickly. If you have this problem, try enjoying your probiotic drink after a meal to lessen the symptom.
