BreathiZen is four pumps, once a day, and each bottle is sold as a 30-day supply. So the simple answer is 120 pumps of daily use per bottle.
Two bottles is 60 days, three is 90, six is 180. That maps onto how long botanicals usually need to show their best — a few weeks for the first changes, a few months for the full picture — which is why the 3 and 6-bottle packs are the ones most people pick.
One bottle = 30 days of four daily pumps, as sold.
Keep it by your toothbrush, use it every morning, and judge it at the end of the first bottle rather than the first week.
