I was REALLY disappointed to see Carrageenan as an ingredient. HORRIBLE ingredient. Do your research. I avoid that ingredient...causes inflammation. And you know what inflammation contributes to? ...high blood pressure, diabetes... It's actually used to 'create' inflammation in testing...I would NOT buy this toothpaste. It also has glycerin in it and it's the FIRST ingredient. Terrible taste, I felt like my teeth were not being cleaned. Mind you, I brush my teeth for two minutes at least twice a day. I also began to experience toothaches after a while. I'll stick to my dentist approved toothpaste, thank you! The mouthwash was even worse.
