I have not tried it but I have never found any OTC product to be too useful in treating UC. Some have great luck with certain supplements, probiotics and herbals but nothing with this type of slick marketing that makes claims of curing every illness from dental issues to reproductive health and everything in between. Did you see their website? It looks like a big scam. I wouldn't order that product. I wouldn't take it if it were given to me for free. I hate companies that lie to people and deceive them with false gaurantees.
When I search google for Digestacure, the 3rd link down is ripoffreport. Never a good sign! Also, the saved searches were "digestacure fraud" digestacure complaints"
