I purchased Aliness Sodium Butyrate supplement which was delivered just over a week ago. I purchased this as I have for several years suffered persistent symptoms of irritable bowel symptom. I have tried many different strategies for reducing my symptoms, including withdrawing specific food substances and increasing my intake of probiotics, and enzyme supplements to help complex plant sugar groups. All of these methods have worked to an extent but the symptoms persisted. Having read several research studies about the potential protective role in the colon of the bacterial fermentation product butyrate, I started to look for a supplier and came across Aliness. So far after a week of treatment, I have seen real progress and a diminishment in my symptoms, particularly discomfort and bloating. My only reason for not giving a 5* score is that I have not been taking the supplement sufficiently long-term to know whether my symptoms will continue to dissipate. However, I will return with another review in the future. This company provide clear information with a well-organised website. They delivered the supplement in good time and it was well packaged. The cost of this supplement is also realistic and fair.
