I've been a natural deodorant user for 10+ years. I recently saw Doc Spartan on Shark Tank and loved that it's natural, made in Portsmouth, OH, and Veteran-owned. It's a great product. Smells good and keeps me smelling fresh all day. If you are transitioning from non-natural, it may take your body some time to adjust (i.e., you may smell for a bit before it truly works).
