I got these for my dad who has suffered from terrible constipation ever since ever. We first heard of these as part of Dr Groups liver cleanse. They work. They work really well. You just need to figure out how many you need for normal bowel movement and the big bonus with these is that they are non habit forming. They caused no side effects what so ever. Really do recommend these if you suffer from constipation. If used as part of the liver cleanse then we found that the number of tablets you need following the completion of the cleanse dramatically reduces with the more cleanses you do. It’s worth visiting Dr groups website and then ordering the liver cleanse kit from the Finchley clinic.
