NutriBiotic Deodorants are long-lasting and contain grapefruit seed extract, witch hazel, and aloe. Made without Aluminum chloride, which is in antiperspirant deodorants to block sweat ducts and keep perspiration from escaping. Aluminum chloride can be easily absorbed, so it can be found circulating throughout the body. Aluminum is a toxic metal, which is why NutriBiotic Deodorants choose not to include this in their deodorants.
