Answer: The recommendation is 2 ounces per day.
Mornings: Drink 1/2 oz. (1TBSP) APeX concentrate and hold in mouth as long as you can; the longer the better, up to 30 minutes, and then swallow. Repeat this at least 30 minutes after your last meal of the day.
Daytime: Put 1 oz. (2TBSP) in 20 oz. to 1 liter of clean, filtered water. Drink this throughout the day, in addition to your normal water intake. Repeat daily. Note: 1TBSP is 1/2 oz.
