Fortunately, I have no need for this product. However, one of the loves of my life does need this product and is benefiting from using, **Nature's Way Primadophilus OPTIMA** for his diverticular disorder. **Warning, please do not take this product for a medical condition, until you first talk to your doctor about this supplement.** My love had for the past two years symptoms of nausea, vomiting, gas, bloating, constipation alternating with diarrhea. Activa Yogurt, and a diet high in fiber was my hubbys' doctors' recommendation. Ginger (as a supplement) he took for the nausea and it worked beautifully. However, the gas, bloating, constipation alternating with diarrhea persisted. **If you are uncomfortable (as is my husband) about discussing, hearing or reading about bodily fluids and functions, please stop here.** Pain, frequent loose, watery and bloody stools became symptoms that were impossible for my husband to ignore. You see, in the inner lining of my husbands' large bowel over time, pouches developed. Whenever food got caught in these pouches, they'd become inflamed and infected. Waste matter, or stool would move slowly in his colon, thus, allowing time for food particles to become trapped and causing inflammation and infection. Unfortunately, diverticular disorders run in his family; but, generally, this is a disease of lifestyle (lack of exercise and a low-fiber diet). A less invasive form of surgery was performed on his colon, and instructions to increase his fruits and veggies, and whole grains. This has helped immensely with the bloating and gas; because, this bulk keeps his waste moving quickly through his bowels. **Nature's Way Primadophilus OPTIMA**** **I discovered at WHOLE FOODS, and consulting with his doctor she agreed it might help with his occasional flare-ups, and it has! This acidophilus product is being taken to boost his levels of "friendly bacteria" in the gut, as a means of replenishing beneficial intestinal microorganisms that diarrhea flushes out of his body, which, is in the long-run meant to improve his bowel health. **Nature's Way **has several **Primadophilus **products on the market. One difference between these products is the true potency of the probiotic; ie 10 bacterial strain formula versus a 14 bacterial strain formula, or 5-10 billion versus 35 billion therapeutic organisms (CFU's). **Nature's Way** claims **Primodophilus OPTIMA **provides a broad diversity of strains commonly found in the human digestive tract; also, it is said, each strain is said to provide its own unique benefits. To protect the potency of this product you must keep it refrigerated. Also, it is said to be designed to meet the needs of all ages. The list of supplemental facts is lengthy,so read the facts ...... again, i**f you or a loved one have a medical condition, talk to your doctor before taking this supplement.** This is our second bottle of this product, and I only purchased it initially because of it's potency, 35 billion CFU's (colony forming units). This second bottle is because my husband says, `it's worth the price, it works.' My husband rates it 4-STARS because, `it hasn't cured me, totally', he says.
