The Puritan's Pride acidophilus is a great value and great addition to your healthy lifestyle. So often I have needed a little something to help with my digestion and these capsules really take care of any digestive issues I may have. If you are someone that is on antibiotics for an infection, that also kills the good bacteria in your system needed for your overall digestive health. Taking these acidophilus capsules really takes care of any problems the antibiotic may cause you and keep you in good digestive health. Puritan's Pride carries quality vitamins and supplements at very affordable prices. They are a great company to order from for fast shipping too. Effectiveness I have found this brand to be more effective than store brands that you can buy. Ease of Use This acidophilus is very simple to use - just take a couple capsules - no mixing or powders. Immediacy These capsules work great and fast.
