I bought a pack of 30 from Walmart a few days ago. I've had problems with IBS for most of my life and diverticulitis. I've had Methotrexate chemotherapy shots recently for 7 weeks in a row (for Rheumatoid arthritis) and it really flared up my stomach - with bloating, gas, acid reflux, diarreah, and constant pain and swelling on the right side (yeah, I've been having a great time of it!!!! LOL). I've tried eating low-fiber, low residue foods, DanActive yogurt drinks, Aloe juice, Zantac 150, etc etc. Finally, my stomach is settling down and the pain has subsided. I am eating more normally now without suffering. I highly recommend this particular product - The Enzymatic Pearls Elite. NOTE: All their probiotics are not the same formula. Here's the ingredients: Serving Size: 1 capsule Amount per capsule Proprietary Probiotic Blend Lactobacillus plantarum, Bifidobacterium lactis, Lactobacillus acidophilus and Bifidobacterium longum 5 billion CFU ** **Daily Value not established. The one Walmart sells on the package says: Enzymatic PROBIOTIC PEARLS HIGH POTENCY Digestive Health. The same exact formula as the Enzymatic Pearls Elite. Same thing. Good luck and happy tummy to you - it really works
