I don't usually do reviews, but I have had such great results from these supplements with my son, I felt like I had to. My 7 year old son has had chronic constipation off and on for the past few years. I hate to give him chemical products (like miralax) on a regular basis. I started these a few weeks ago and he is a different kid. I have heard that constipation causes fatigue and exhaustion (due to build up of toxins). Since taking these, he is having a poop daily and has so much more energy (don't know if that is the vitamin b in there too). He is a new kid, making healthier eating choices and all and all, so much better. So happy with his results, I may try the adult version. The only disadvantage is that he has to take 4 per day and his sister is taking 2, so we go through them pretty fast, but it is still worth it in my opinion.
