Zadi toothpaste is seriously the best toothpaste I have ever used. There is no sticky toothpaste residue that other brands leave in your mouth after brushing. Zadi toothpaste has some sort of magical property where my mouth is clean even AFTER eating meals! Plaque buildup is MUCH LESS than before, with less brushing required. Also, my mouth is much cleaner when I wake up in the morning, even before brushing. Makes you think: what do the OTHER brands have that ENCOURAGES a dirty mouth?! Either way, Zadi toothpaste is very pure and I am happy to have it.
