While there is no known cure for this disorder, CystoProtek can help reduce bladder damage and pain, improving the overall symptoms in patients with IC/PBS. An all natural oral dietary supplement in a soft gel capsule. CystoProtek is a clinically tested supplement that does not require a prescription. Clinically Proven Effective IC/PBS is a chronic inflammation of the bladder that occurs more in women, but also affects men. Varying from fairly mild to extremely painful, symptoms can include urinary urgency, urinary frequency, nocturia and pelvic pain. The Interstitial Cystitis Association reports that recent data indicates there are more than 700,000 cases of IC in the U.S. For the hundreds of thousands whose lives are significantly impaired due to pain and the need to urinate excessively, CystoProtek was demonstrated in two clinical studies to be effective in reducing the pain and symptoms of IC patients. Anti-Inflammatory Properties This natural oral dietary supplement comes in a soft gel capsule form. Cystoprotek is made with anti-inflammatory properties glucosamine, quercetin and rutin to help reduce bladder damage and pain, and glucosamine sulfate, chondroitin sulfate and hyaluronate sodium help replenish the damaged glycosaminoglycan (GAG) protective layer in the bladder. Chondroitin sulfate is one of the main components of cartilage and muscosa layers, forming the connecive tissue that holds muscles, nerves, and blood vessels together. Sodium hyaluronate is another component of protective tissue, including the GAG layer of the bladder, and is essential in the rebuilding process. Extracted from the saphora plant, rutin is a non-acidic natural flavonoid that adds additional anti-inflammatory qualities and liberated quercetin in the intestine, making absorption easier. CystoProtek is not a cure for IC. At this time, there is no known cure for the condition. Additionally, it is important to understand that CystoProtek is not an analgesic. It may take three to four months to offer a relief of symptoms. In clinical study Cystoprotek was well tolerated by patients ingesting 4-6 softgel capsules per day for 4-6 months. Features
