Magnesium Bicarbonate Instructions

  1. Chill a 1 liter bottle of carbonated water. The colder the better but not frozen.
  2. Measure out 1000mgs (a level 1/4 Teaspoon) of magnesium hydroxide
  3. Very gently remove bottle from fridge or freezer. The more you move the bottle around, the more carbonation will escape.
  4. Remove bottle cap and pour in magnesium hydroxide, quickly replace cap tightly.
  5. Shake the mixture for 30 to 60 seconds.
  6. Refrigerate or put the bottle in the freezer. 1 hour in the fridge or 30 minutes in the freezer, set a timer so you do not forget!
  7. Take bottle out and shake it again for 30 to 60 seconds. This makes sure that the maximum amount of reaction takes place. Place back in fridge for another hour. Water will turn from cloudy to clear.
  8. Experience the awesome powers of magnesium bicarbonate water!
  9. One ounce of bicarbonate water contains approximately 16mgs of super-absorbable magnesium. We like to add our magnesium bicarbonate to juices. Example, apple juice or orange juice.
  10. Start low and slow. One ounce at a time is a good place to start.
  11. Always keep refrigerated and cap on tight.
  12. No need to shake anymore. If there are flakes on the bottom leave them and do not drink as those flakes did not react. Next time, use a bit less magnesium hydroxide, or shake a bit harder and longer during the shaking process.
  13. Bottle should be good for about a week and then the magnesium starts settling out. We drink a bottle every two or three days.
  14. You can experiment and see if you are able to add more then 1000mgs of magnesium hydroxide to the bottle.

Always mixes perfectly!

This magnesium always dissolves completely when I make magnesium bicarbonate water. It’s really fast too unlike some powders I’ve used before.

Game Changer

This magnesium hydroxide is exactly what I needed in my life. I recommend mixing 2 servings per 1L & shaking for 5 min. Tastes funny so I recommend serving with a little grapefruit juice over ice.

Makes the best deodorant

Just add water to make a thick consistency and apply a small dab with fingers. It does not stain clothes and works wonderfully.

Mg Water Works

Its hard to find food grade MgOH so I was happy to get the double sealed package so quickly. The instruction sheet was very helpful. So easy to do! Because our water is so hard I use distilled water and thought at first it would taste bland but found it has a pleasant, almost sweet taste. My wife just adds a little piece of lemon to hers. I sleep better and my tendonitis is almost gone now after a couple weeks.
