For the past 90 days, I have been taking a high quality 60 billion strain probiotic daily....and it has virtually eliminated my AS pain. I have stopped all NSAIDS. I am truly amazed. I hope others will try this approach to gut healing and will also have the superb results that I have experienced. Probiotics seem far safer to me than the biologics pushed by mainstream medicine. This source of probiotics works well for me www.renewlife.com I am sure there are others too. Best to all !
