How to Make Structured Magnesium Bicarbonate as a Drinking Water Additive


Making a structured magnesium bicarbonate solution to use as a health promoting water additive is both an easy and affordable task!

Supplies needed:

1. A single liter of chilled, generic soda water, which is simply carbonated distilled water (CO2 in distilled water)

Milk of Magnesia2. One container of Milk of Magnesia – Please make certain you purchase pure milk of magnesia with no additional flavoring or additives. One desires simple and plain magnesium hydroxide ( Mg(OH)2 ).

For a supply of pure magnesium hydroxide, alternatively, you can purchase the powder from here: Pure Magnesium Hydroxide Powder (250 grams)   .  Follow the same directions as given below, only, use 3.6 grams of the powder per liter of CO2 Water (just under one teaspoonful).  Add the powder directly to the seltzer water.  If you experience problems getting the magnesium to mix/react, then simply add the magnesium powder to a few ounces of water first.  Mix well, and then add the solution to the carbonated water!

How to prepare:

Shake the bottle of Milk of Magnesia well. Measure out three tablespoonfuls of the white, milky solution.

Open the bottle of soda water, and quickly pour out about three tablespoonfuls of soda water. Then, pour in the three tablespoonfuls of milk of magnesia. Quickly put the cap of the soda water back on. Shake vigorously. Then, place the modified soda water in the refrigerator for thirty minutes. After thirty minutes or so, remove the water, and shake vigorously once more. The solution should become cloudy.

Refrigerate once more. After another 30 minutes or so, the magnesium bicarbonate solution will be ready to use. It should, at this point, be crystal clear. If there is any undissolved magnesium resting at the bottom of the bottle, simply ignore it.

The chemical reaction that produces the magnesium bicarbonate:

Mg(OH)2 + 2CO2 —> Mg(HCO3)2

In essence, the magnesium hydroxide comprising the “milk of magnesia” reacts with the CO2 in the “soda water” to form magnesium bicarbonate.

There are individuals out there who slowly drink this solution straight, drinking small amounts at a time. However, we prefer to use this as a concentrate, adding small amounts (about an ounce or per gallon) to high quality drinking water, as specified in my post An Introduction to Drinking Water.

Unlike other forms of magnesium, magnesium bicarbonate is about 50% bio available through internal use. 50% is adsorbed into the body where it becomes available to cells, and about 50% enters the colon.  Therefore, drinking magnesium bicarbonate water can help re-hydrate the colon and reduce constipation.

Similar water, with trace minerals added, sells for about $32.00 a Liter in Australia, under the commercial name “Amazing Micro Water”.

According to noted magnesium author Marc Sircus, bicarbonates are the perfect delivery system to transport magnesium directly into the mitochondria.

To quote Sircus:

“It was actually the dedicated work of Dr Russell Beckett, a veterinarian with a PhD in biochemical pathology that paved the way to understand the significance of bicarbonate acting in conjunction with magnesium. He has formulated “Unique Water” which, it has been asserted, slowed the aging process and increased the length of life of humans and other mammals and could be used to treat all inflammatory and degenerative diseases. Unique Water is water containing magnesium bicarbonate at an alkaline pH value. Dr. Beckett’s theoretical and experimental research has resulted in the understanding how important both of bicarbonate and magnesium ions are in human physiology and how they work together to optimize human health and the ability to recover from disease.

Bicarbonate ions working alongside magnesium would naturally create the conditions for increased glucose transport across cell plasma membranes. Bicarbonate ions without doubt create the alkaline conditions for maintaining the enzyme activity of pancreatic secretions in the intestines. Bicarbonate neutralize acid conditions required for inflammatory reactions hence sodium bicarbonate would be of benefit in the treatment of a range of chronic inflammatory and autoimmune diseases…”

“…Magnesium does not readily reach the mitochondrion, but if plenty of bicarbonate is available the bicarbonate will act as transport into the mitochondrion. The only problem is that the few magnesium bicarbonate products available for sale are expensive compared to using magnesium chloride and sodium bicarbonate individually. It is possible though, that one can always make their own magnesium bicarbonate.”

Making magnesium bicarbonate a part of a balanced and vibrant drinking water is an exceptional idea. Please note, however, that individuals with chronic inflammatory conditions or calcification of arteries may have to go slow, and limit the amount of magnesium bicarbonate taken on a daily basis until the body goes through a cleansing crisis. This is one reason why we suggest using smaller amounts of magnesium bicarbonate added to drinking water, rather than drinking the concentrated form directly.

That, and just the right amount of magnesium bicarbonate added to good drinking water makes the water taste simply perfect! Be sure to view the article/post on an introduction to drinking water in order to learn how to make the perfect water for your individual preferences.

As with all magnesium products, the symptoms of excessive use are loose bowels and muscle cramps.  Reduce dosage if either of these symptoms occur.

16 ounces of the magnesium bicarbonate concentrate will contain about 1500 mg of elemental magnesium.  No more than 16 ounces (1500 mg.) of the concentrate should be consumed daily.

Improving the Water Quality – Adding Structure and Trace Minerals

From a holistic/naturalist standpoint, magnesium bicarbonate water is not very natural.  Furthermore, any time that you push excess magnesium through the body, it is a good idea to balance things out by ingesting other healthy alkaline minerals.  This isn’t a real issue, since nearly everyone in modern society is magnesium deficient.  It’s difficult to deliver too much magnesium into the body via mag bicarb.

That said, why not improve the health benefits of this water?

To do so, simply blend in some high quality salt sole once the magnesium bicarbonate is ready.  Making a very high quality salt sole is easy, and you might be surprised at the difference doing so makes.  The following is a link to a blog post and tutorial on how to make water to use with therapeutic healing clay.

Simply follow the instructions on how to prepare Bamboo Dragon Sole, Himalayan Salt Sole, or both.  This involves purchasing very specific natural salts, and creating “brine” (sole).  Then, you simply add about 0.5 – 1.0 ml to your magnesium bicarbonate; even just a few drops will do!

How to make a high quality water using salt sole

Conversely, many high quality structured drinking waters lack bicarbonate content.  Bicarbonates act as buffers, helping to neutralize acidic waste.  It is a great idea to add a small amount of magnesium bicarbonate to purified and structured water.  An example would be high pH water where the pH is shifted with minerals such as potassium hydroxide.  Potassium hydroxide drinking water can be used to flush the body of acids, whereas magnesium bicarbonate drinking water can be used to help neutralize acidic waste.

Both of these “central ideas” can be utilized together.  Water can be created to both replenish the main alkaline minerals used by the body and help neutralize acidic waste!

52 thoughts on “How to Make Structured Magnesium Bicarbonate as a Drinking Water Additive”

  1. I want to produce magnesium bicarbonate from magnesium oxide adding it in the first step to water for getting magnesium hydroxide out of it.
    But I am not quite sure if there is no problem with this additional step and with the fact that the magnesium oxide is “only” 70-75% chemically pure.
    Could anybody help me with that issue and also tell me what proportions should I use in every single step?

    1. Hi Matt:

      I wouldn’t be able to help you there. What you could do is simply slowly keep adding magnesium until it starts to crystallize and fall out of suspension to the bottom of the bottle, making careful note of how much you’ve added to the seltzer water.

  2. Is there a reason why you don’t drink the concentrate straight? I have been drinking it straight but wonder now if I’m missing out on the benefits by doing so. Any information on this would be appreciated.
    Thank you in advance.

    1. Hi Donna:

      No specific reason; after adjusting to the effects of Magnesium Bicarbonate, you are certainly welcome to use it straight, many people do. Using it as a water additive is a way to make sure you have bioavailable magnesium titrating through your system throughout the day, and without the “strong” taste of using it straight.


    Good evening Jason,

    I have been making magnesium bicarbonate from your blog tutorial ever since you posted it. The first couple of times, it turned out great — nice, clear, perfect. But these past 2 times I’ve done it, all I get is milky seltzer. It never turns clear, not like before. Would you be able to troubleshoot this? I’m puzzled, since I’ve followed the same procedure each time.

    Fresh bubbly chilled seltzer water – 1 L
    Plain milk of magnesia – 3 T

    Remove 3 T seltzer water. Add in 3 T milk of magnesia. Cap & shake. Frig 30 min. Shake. Frig 30 min. And voila!

    But no! It’s still cloudy!??

    I use this as an essential component of electrolyte water that I use daily, so I need this to work. Any suggestions?


    1. Hi Janis-Marie:

      Usually, this is due to a problem with the seltzer water. If seltzer water sits on the store shelves for too long, it slowly starts to lose its carbonation. If used to make a carbonated drink, one might not notice, as the actual level of carbonation is hard to gauge visually and/or by taste. I would suggest trying a different brand, or trying a different store, and see if that helps!

    2. I wonder if some brands selling milk of magnesia neglect to list other ingredients. I don’t see why other ingredients would be necessary… or if they’d affect the reaction between CO2 and magnesium. Does it taste the same as your better batches? Is it possible the water source has changed for the brand that sells your carbonated water? And if so, would that affect how the magnesium bicarb acts in solution? I haven’t really thought about it – just posing some questions. I’ve only made a couple batches myself, and it turned out a little different each time with the same ingredients (but still good both times).

  4. In case anyone else was thinking of precipitating or otherwise collecting magnesium bicarbonate and turning it into a fine, dry powder… I just read that it only exists in aqueous solution. (darn) It apparently decomposes during drying to product magnesium carbonate and CO2. So don’t waste time trying to figure it out like I did!

    My question, though, is if the crystals I see all over the side of my glass pitcher are mag bicarb or the simpler mag carbonate. If it’s magnesium carbonate, with the stuff in solution still mag bicarb, I wonder how/why it happens, and how I’d prevent it from happening. I did add extra purified water after the fact, figuring that would give my science experiment more room to breathe. I didn’t add water to the last batch, and it never crystallized.

    1. Hi Colby:

      Yes, it is only an actual bicarbonate in hydrated form. Any excess magnesium in the solution will simply settle out at the bottom of the container; it’s not a big issue. I’m not sure the exact form of the precipitate, but it’s probably simply oxidized magnesium.

  5. Hi,
    I made the magnesium bicarbonate using seltzer water & MOM (that has just pure water with no additives). On the 2nd day the seltzer appears to have gone flat.
    My question:
    Does the magnesium remain a bicarbonate even after the seltzer is flat or should the seltzer still have fizz to keep the magnesium a bicarbonate??

  6. Hi eytonsearth,
    Many thanks for the info and the quick answer!!
    Definitely appreciated!
    Another question, If I use a Soda Stream Source to make seltzer water, I’m not sure how much carbonation would be adequate for making magnesium bicarbonate. The SSS has three levels of carbonation light to high. Would the light (bottom lower pump) be enough cO2 for a one liter bottle or should I use the highest level?
    Love your site BTW It’s very helpful.

    1. Hi June:

      You can use a a Soda Stream, but there is no real way to get the numbers perfect without trial and error. The good news is: If you use too much MOM/magnesium oxide, the only thing that will happen is that the extra magnesium will fall out of suspension and rest at the bottom of the container. Use the cleanest water you can (distilled water).

  7. Hi again,
    Sorry I didn’t frame my question well enough in my previous message.
    How much of the magnesium bicarbonate solution (as described in your article) would I add to 4 litres of distilled water for daily drinking.

    1. “we prefer to use this as a concentrate, adding small amounts (about an ounce or per gallon) to high quality drinking water, as specified in my post An Introduction to Drinking Water.”

  8. Hello,
    Sorry for asking the question in my previous messages. I had only skimmed over your article yesterday. Of course the answer is about an ounce per gallon.
    Thank you for this information.
    I have been drinking distilled water for about 5 years, so no doubt I am in dire need of magnesium bicarbonate.

    1. Hi Sharon:

      You can use Pelligrino, but I don’t know exactly how much CO2 there is in the water compared to commercially produced water; I therefore don’t know how much magnesium hydroxide to add to the Pelligrino. You could, of course, experiment.

  9. Hi there, this is my first time here. I followed your recipe and one from Dr. Sircus and made the magnesium bicarbonate as a water additive. Today, I noticed you add only about an ounce of the additive to drinking water. I put 1/3 liter (about 11 ounces) per Dr. Sircus measurement of this additive which brings the water up to 8.5 pH.. If I add only 1-2 ounces to a gallon of water, how much pH would this add up to be? The only water available to me is distilling my own water.

    Another question: I drink 9 glasses of this water daily. Is this too much? If I am only to drink it for four days, (I don’t remember where I read the 4 days) the only water I have is distilled. Wouldn’t it be better to drink all my water made with this additive so I don’t have go back to drinking distilled water as is?

    1. Greetings, Angel:

      This particular article is about using Magnesium Bicarbonate as a drinking water additive as apposed to using it to try to achieve a therapeutic effect (like the Sircus article).

      As such, it recommends a “do it and forget about it” dosage level.

      You can use more, but as you amp the amount, watch out for loose stools and/or cramping. It’s pretty rare, but I’ve run into a few folks who reach their magnesium threshold, and either develop loose stools or start getting leg cramps.

      When I get the chance, I’ll measure the pH. We don’t recommend/suggest using magnesium specifically to raise the pH of water due to its general lack of absorption. Individuals who DON’T need to correct pH imbalances or who DON’T have detox issues should probably be drinking water with a pH of about 7.5.

      If the pH is higher (for LONG term use), then it would be better to make sure that there is potassium, calcium and sodium present as well, or use potassium since it is easily flushed through the body.

      All of that said, I’m sure that many people drink higher pH water with magnesium bicarbonate over the long term and have no issues at all.

  10. Thank you for replying so quickly! I have been making and using Magnesium oil over the last month; and it has benefited me hugely. I use Himalayan salt; and will make the Sole to add to my distilled water per “Improving Water Quality” in the article above.

    I have been drinking magnesium bicarbonate in my distilled water for about 3 weeks now. Two nights ago, all joints on both of my hands hurt when I bent the fingers. This scared me a little. I re-read your article on magnesium bicarbonate and started adding more distilled water to the water I had left in my gallon jar so that I would be getting less of the additive in my drinking water. I am not sure if the joint pain on all my fingers was a result of adding too much of the additive into my gallon of drinking water; but it took two days for the joint pain to stop. The next time I make the additive, I will follow your recipe and use only 1-2 T of the additive.

    I am most interested in restructuring my distilled water and am hoping that using less of the additive will still do that; however, I don’t know how to reach 7.5 pH in my distilled water by using the additive. Perhaps when you check this out, I will know the answer to that as well. Thanks again! Love your site!

    1. Hi Angel:

      Chances are, the magnesium bicarb is dissolving calcium deposits. This is a good thing. It will still happen if you use LESS Mag Bicarb, but chances are it will happen so slowly that you won’t notice it.

      I just made some magnesium bicar myself, so I will check out the pH. Since your joints reacted like they did, you might benefit from drinking a more alkaline water for quite some time. I would check out my other two blog posts on the “symphony of biochemistry” and the follow up article on alkalizing. You might want to do the saliva pH challenge test, and test your saliva throughout the day for a week or so to see if it is a stable 7.0.

      1. Hi Angel:

        Adding 1 tbs of Mag Bicarb to one gallon of water yielded an end solution with a pH of 9.0.

        To be clear, when I said the best drinking water is about 7.5 pH, this is for people who are completely healthy, with healthy eating habits as well.

        For individuals with chronic issues, it might be one, two, or even three years of alkalizing/remineralizing before the body reaches its natural homeostasis. For people with SAD dietary habits, it may always be a good idea to drink water with a higher pH!

  11. Thank you! I will follow through on your suggestions, and update you as to my progress and success in the weeks ahead.

    A few minutes ago, I read all about you. When I taught elementary school, it was quite a challenge working with an occasional young lad who needed freedom in his studies to express himself, excel and go beyond what most boys accomplished at his age. I am glad that you have been successful in knowing yourself, in seeking knowledge and wisdom, and in putting these to use in reaching out to others with your experience and expertise. I am sure you are an inspiration to many others! Blessings on you!

  12. I practice the 8 laws of health. NEW START: Nutrition, Exercise, Water, Sunlight, Temperance, Air (fresh), Rest and Trust in God. I have been healthy through out my life. I am vegan and have eaten that way for over 21 years, I keep a daily journal of everything I eat, and drink. I eat most of my food organic. I do not eat processed foods nor sugar. I do not have any chronic health issues. I also take supplements, but have been rethinking my use of those , thinking using liquid and similar type supplements might be more useful to my body. Although I have recently learned about magnesium oil and am using that now in place of capsules, I do believe that I got benefit from taking magnesium orally; however, I believe magnesium oil assimilates best in my body and is the better way to go!

    The down side is that ten years ago I started drinking distilled water due to poor available drinking water where I lived in Colorado USA at that time. I also took a course of study relating to health. During the two years, I spent more time sitting than exercising, because of such an interest in my studies and research that I was consumed. Staying up late studying and not exercising on a consistent basis was not wise. During the last few years, I have worked hard to get to bed early: “Early to bed, early to rise, makes a woman healthy, wealthy and wise.” I don’t know about the wealthy part though. And I exercise daily, especially doing a lot of stretching moves.

    If I broke my leg, I’d see a doctor. Other than that, I am my own doctor, seeking wisdom in research and reading, and listening to those who have found natural remedies that make sense and have shown success in healing. I am thinking that drinking distilled water has affected my health in small ways in that my middle finger joint of my left hand looks swollen, but is hard. I do not have pain in it or in any other joints in the fingers of my hands except recently which I already mentioned. Also, over the last year, I have begun to experience arthritis in my hip joints (hip bursitis); but stretching and keeping limber totally remedies that. I wonder now if drinking distilled water over ten years may have played a part in what I am now beginning to experience in my joints?

    Where I now live in rural Michigan, USA. I have well water with a high amount of lime. The water was tested recently for impurities and has none whatsoever. Amazing, I think! I still was afraid to drink it due to all the lime I find in my distiller after purifying the water. The white lime in my distiller is the only color I have deposited in the distiller after it is finished making pure water. I am not sure of much else regarding well water. Perhaps I should be drinking it.

    1. Hi Angel:

      If you read my article, “Water, the Universal Solvent”, you’ll no doubt realize that I take the unpopular position of stating that BOTH sides are right: Distilled water can be good and cleansing, and distilled water can be unhealthy.

      The cleaner you eat, the less you need to use something like distilled water. Luckily, you can use distilled water and modify it to suit, adding minute amounts of trace minerals, and substances like magnesium bicarbonate and/or magnesium chloride.

      It is very hard to eat healthy and be a Vegan. Kudos! Many Vegans run into problems with fatty acid imbalances; way too many Omega 6 compared to Omega 3. This can cause joint issues, as well. The only way to know “for sure” is to have a fatty acid profile test done. It’s expensive, but doesn’t cost a fortune. Unfortunately, you need a natural MD or alternative MD to do the testing.

      As far as drinking lime water? Not the best idea, but this is completely dependent upon how much lime is in the water. If you purchase some pH strips or a pH meter, you can get an idea. If your intuition and taste buds tell you this water is good, then you can trust that; I would still dilute the water down to a reasonable pH. You can also use a PWT meter to dilute the water down to the point that it is not considered “mineral water” any longer.

      I like my base drinking water to be close to distilled; under 50 PPM. Then, I’ll add structure/minerals back into it.

      Some people crave mineral water. This usually indicates that there is something in the water that they are lacking.

      One thing that I do teach is “water awareness”. You can activate the body’s innate water awareness by purchasing a bunch of different types of water. Taste test each one. Ask yourself which water the body accepts/likes the most.

      This is usually the healthiest water “for now”. If the body craves a high mineral content water, or if the body craves pure distilled water, then this water awareness test should be done every few months. The body’s response will change.

      You can even purchase INDIVIDUAL MINERALS, and then add each one into purified water. Body Bio Balance has a kit and instructions on how to do a taste test. This should probably be considered “over kill” and may be a sign of “water paranoia” for some (LOL), but the fact that it does work is very fascinating. If you have four people doing the same mineral testing, the four results will be completely unique. When these same people do a test three months later after correcting mineral intake, the results again will be highly unique, and will demonstrate what one would expect: The body stops craving the minerals that were at one time out of balance.

      All of that said, using a bit of Himalayan crystal salt, or 9XBS salt, is probably the best idea, since it provides naturally balanced minerals in a form that the body readily accepts. If you flush the body with a lot of minerals, *****as long as all of the minerals are in the proper proportion*****, the body is very capable of flushing out what it doesn’t need, unless there is problem with absorption, which would be due to things like electrolyte imbalance, heavy metal toxicity, and sometimes even a genetic component!

      Your well water might be very high quality, aside from perhaps too much lime. You’d have to study the geology of the water table to really get a grasp on the end quality, AND you’d have to test the water to NSF standards to really see what is in it. “Basic” water tests are usually not detailed enough.

  13. Hi .. Can you suggest a rough expiary date for the concentrate? I assume it should be kept in the fridge if not consumed.. Also safty wise, when you mix a tbs of the concentrate with a galon of water .. How many glasses one can have of this mixer on a daily basis and for how long ?

    As you can tell I’m new to this , however
    I cannot thank you enough for your posts .. You are doing so much more good than you imagine .. I am finally able to understand my illness and the reason behind my muscle atrophy which is the result of chronic stress

    1. Hi Anna:

      I would use the concentrate within 60 days to be on the safe side. It’s not expensive to make, so use it as fresh as possible. And yes, please refrigerate the concentrate.

      This article is about using the magnesium bicarbonate as a drinking water additive to make healthy drinking water that can be always be used, without having to worry about anything. It doesn’t go into detail about how to use it as a stand alone therapy.

      The quick answer is that you can drink as much as you’d like for short periods of time. Watch for loose stools and muscle cramping (which would mean you are taking too much).

      Most people won’t be able to drink too much, but I have found a few people who managed to! Remember that if you consume too much of any one single mineral, you risk causing imbalances with other minerals. Most people really need a lot of magnesium, but there will come a point where the body has recovered from magnesium deficiency; where less de-calcification needs to be done in the body; where the excess magnesium is no longer promoting better health. This “point” will be different for every single person.

      So, a strategy of drinking “a lot” of magnesium bicarbonate water for short periods of time; three days to a week for example… is one good strategy, because you can then listen to how the body is responding (by how you feel).

      You can also study the other blog posts about re-mineralizing the body and balancing the body’s electrolytes, as well.

  14. Hi again. Because my Milk of Magnesia contains bleach as a preservative, I purchased, magnesium hydroxide powder as suggested by you as an alternate to using Milk of Magnesia for making Magnesium Bicarbonate. You wrote that if we use magnesium hydroxide powder, we’d need to use about 1 teaspoon. Before reading your recipe for making Magnesium Bicarbonate, I watched someone on YouTube making it using magnesium hydroxide powder. He used 4 grams, telling everyone that was about 3 3/4 t. of the powder to a liter bottle of carbonated water. You say almost 1 t. of magnesium hydroxide powder to a liter of carbonated water, so this man’s amount is almost 3 times more. Is he correct?

    1. Hi Angel:

      …no need to trust me over him (or vice versa). If you use too much magnesium hydroxide powder, it will crystallize and fall out of solution (sink to the bottom). This excess magnesium can simply be discarded after use.

      If, on the other hand, there is no excess crystallized magnesium, this means that you either used the maximum amount, or perhaps could have even used more.

      This will all vary depending on the quality of the carbonated water. Storing carbonated water eventually reduces the amount of carbonation.

      All of that said, I personally like to use the maximum amount of magnesium hydroxide possible, in order to get the highest amount of magnesium bicarbonate. I usually have a small amount of crystallized magnesium left over in mine.

      However, less magnesium hydroxide can be used if desired.

    1. Greetings, Jeffrey:

      As a general rule of thumb, it is better to drink water away from food if possible. This helps to prevent the dilution of stomach acid when digesting food. BUT, this is just a general rule of thumb.

      1. Is the dilution of stomach acid when digesting food the main concern, because my main concern is the absorption of the magnesium bicarbonate?

        1. Hi Jeffrey:

          Most people are highly individual. People with iron digestive systems likely can ignore the issue all together. However, those who are ill may need to pay more attention to the digestive system.

          Magnesium bicarb “digestion” is self limiting. This is probably a good thing. The way to improve absorption is then all about titration. Find a concentration that works for your goals, and poor 2 liters of fluid through the body a day. While it is hard to get too much mag bicarb in the body, it can happen. Watch for general symptoms of too much magnesium: cramping, loose stools. Also, when amping up the concentration, please realize that you will be dissolving calcium deposits. That’s why I recommend people go slow and simply utilize magnesium bicarb and a healthy water additive, and reap the benefits over months and years.

          You, however, are welcome to approach the subject as a therapeutic endeavor. I can’t comment much more than this because I don’t have the data via enough case histories to identify possible problems with this approach. You always need to apply common senses when pushing “too much” of any particular mineral into the body!

  15. Is there some research or data regarding the dilution of stomach acid when digesting food (or not digesting food), and the addition of alkaline fluids?

    1. Hi KB:

      This will be an issue with a very tiny percentage of the population (usually the elderly). This is why this article recommends using the magnesium bicarbonate…as a water additive only… Used in this manner, the formulation is not alkaline enough to cause issues with those whose digestive system is in dire shape (low to no stomach acid/bile production).

      That said, if the magnesium bicarbonate is being used for a actual magnesium THERAPY… meaning, much more is being consumed directly… then one can compensate for this potential problem:

      Drink the magnesium bicarbonate at least an hour away from meals. After consuming the dose of magnesium bicarbonate, wait 20 minutes and then drink some lemon water. The juice of 1/4 – 1 lemon diluted in 8 ounces or more of water (or diluted by 50% in a shot glass and “shot” like whiskey). Use about an ounce of apple cider vinegar just after, or during, every meal (diluted by twice the amount of water).

      Not only will this provide the body with beneficial acids, but also a good balance of minerals to compensate for drinking the magnesium bicarbonate. Using lemon and ACV is also corrective for individuals with weak digestion. However, iodine therapy may be required if iodine depletion is responsible for the body’s lack of stomach HCL production.

      Thanks for posting!

  16. — ignore my last post, this one fix the wrong word used, it should be Mg Bicarbonate concentrate not MoM concentrate

    45ml (3 Tablespoons) of plain Milk of Magnesia containing about 1500 mg of elemental
    magnesium [dissolved in 1L of water], so 2 oz of *Mg Bicarbonate* concentrate contains 90mg of elemental magnesium, not 4 oz as mentioned in your article, is that right? Just to make sure…

    1. Hi Heman:

      Thanks for pointing this out. I copied the numbers from another source without checking them.

      That said, there is 3600 mg of magnesium hydroxide in ~3 tablespoonfuls of milk of magnesia. This will contain about 42% of actual elemental magnesium.

      This means that for each 16 ounce container, there will be about 1512 mg of actual magnesium.

      The figures that I used showed how much magnesium hydroxide would be in the 16 ounces, not how much elemental magnesium.

      I have made the correction to avoid further confusion. Thanks for taking the time to post.

  17. I made up this concentrate and added it to my tap water which is 7.4, the concentrate took it down to 7. I also tried it in carbonated water and it lowered it to 5.6. Is this normal or should PH be higher? What is the ideal PH?

    1. Hi Derek:

      Just like distilled water will test acidic after steam distillation, even though it is very close to pH 7.0, the shift in pH with the magnesium bicarbonate can only be due to excess carbon dissolved into the water. Carbonic acid is not actually acid-forming, and will not negatively impact the body, while the magnesium content is still alkaline forming in the body.

      So while I do not use magnesium bicarbonate as an “alkaline drinking water”, the magnesium is still bio-available as one of the core macro alkaline minerals that the body regularly needs to modulate pH.

  18. Here’s a question (and let me know if I’ve missed any explanation for it): if magnesium bicarbonate is more or less ‘CO2-acidified’ MgCO3 in aqueous solution (thus becoming Mg(HCO3)2)… then by purchasing a strong sparkling mineral water and adding small amounts of pure MGCO3 powder and shaking, wouldn’t you end up with quite a lot of magnesium bicarb suspended in solution? (After the fizzing reaction I mean.) I’ve tested this, and it *appears* to be working, albeit with a larger amount of sediment than magnesium hydroxide. If it’s working to some extent, is the issue just left to the percentage yield? Or… am I only witnessing a fizzing as the MgCO3 disperses to saturation in the water, meaning I get nearly zero Mg(HCO3)2?

    The reason I ask at all about magnesium carbonate is that it seems like I’m more able to find it pure (and apart from pharma). And, it has several other uses that make it valuable around the house.

    Anyway, what are your thoughts?

    1. Hey Colby, good to hear from you.

      …exactly. You can use any carbonated water, the difference will be in the concentration of the end “yield”. If there is the same amount of carbonation as with plain carbonated distilled water, then the amount of magnesium bicarbonate produced will be close to the same.

      1. Okay, got it! And it’s good to see you’re still active with your site. (I still refer someone every now and then! Every time I browse EytonsEarth I find something I didn’t know/remember.)

        Thanks for your help Jason! (Or other admin?) Wishing you well!

  19. Hello Eytonsearth,
    I made the 1Liter bicarbonate water. I would like to add the liter to a 5 gallon jug of water minus the 1 liter. Can you please tell me how much of the magnesium I would get in an 8oz serving?

    1. Magnesium Hydroxide contains 42% elemental magnesium.

      Since you are using 3.6 grams of magnesium hydroxide per liter of CO2 water, you are getting 1.512 grams (1,512 mg.) of elemental magnesium per 1 liter bottle.

      If you add the entire liter bottle to a 5 gallon container of drinking water, you will get 302.4 mg of elemental magnesium per gallon.

      From here, you just need to determine how much a “dose” of water is.

      There are 128 fluid ounces to one gallon of water. If your serving size is 8 ounces, there will be 16 servings per gallon.

      if there is 302.4 mg of magnesium in one gallon of the drinking water, to determine how much magnesium is in 8 ounces, you would simply divide 302.4 by 16. There would, then, be 18.9 mg of magnesium in eight ounces of water… if my math is correct! 😉

  20. I encourage everyone to buy the powder and NOT the Milk of Magnesia liquid. ALL MOM have sodium hypochlorite as an additive. Your pure water will be spoiled by BLEACH!!! if you don’t buy the powder of magnesium carbonate. BLEACH I TELL YOU, BLEACH!!!

    1. …I absolutely agree that people should use the purest product possible, when it is available. I also agree that people should be HIGHLY educated about whatever substance they are putting in their body.

      The reason I’ve left this article alone with the option of MOM, is that in many countries, the only thing people can get is this type of product.

      However, just so folks know, sodium hypochlorite has only 1/3 the oxidation power of sodium chlorite, which many people use as internal therapy… it also has far less oxidation than hydrogen peroxide does.

      So, in a case like this, there is nowhere near enough sodium hypochlorite to cause an actual biological effect. IT WILL OXIDIZE what it is mixed with, but this water is not anti-oxidant water, so there is no net consequence. If one wants to be certain, one simply needs to mix in a dash of antioxidant salt and wait a few moments. This will neutralize any oxidative substance in the water.

      To be ultra-clear, there is nothing toxic about the chloride atom. It’s only what is done with it that gives it an actual biological effect. If the molecular charge is neutralized. Furthermore, without chlorides in the blood, we could not survive, it is one of the most important atoms in the body, and makes up nearly all of the substances the body uses to neutralize acids (alkaline salts).

      If you can get the powder, I would always prefer using that!
