How to Make Magnesium Chloride Concentrate

15 April 2016

I was delighted to finally find a source of magnesium chloride that claimed to be edible.  Here is a link to the product:  Magnesium Chloride.  For a while I was using the body spray magnesium oil which is a concentrated form of magnesium chloride and water or alcohol (Mag-A-Hol).  The only downside of the spray is you really don’t know how much you’re getting both because spray lengths are variable and skin intake is likely variable based on the individual.

The only issue I have with using magnesium with alcohol is that you rub it on your torso’s fat.  Your fat cells act like a little endocrine centers producing hormones, especially estrogen, through the use of the enzyme aromatase.  Alcohol increases aromatase activity. Magnesium inhibits it.  Seems counterproductive to mix these together.

Magnesium Chloride Recipe

Magnesium Chloride Mixture Prepared

As an engineer type, I like to know how much I’m actually getting of a given substance.  Because too much of a good thing can be a bad thing, and too little of a good thing doesn’t do anything.  Greenway Biotech does include dosage instructions on the bottle, but does not include any detail on how much magnesium you’re getting from the magnesium “shots.”  While doing their shots, I’m certain you’re getting enough magnesium to do “good” things, it’s still not granular enough for me.

For those new to the magnesium scene, a lot of blogs just seem to parrot one another without actually looking at Pubmed or studies.  Some say Magnesium Citrate is the best.  Some say Magnesium Glycinate is the best.  I’ve used both of these forms, and overall they seem fine.  But I still like magnesium chloride, or the form I posted about recently in my Magnesium Carbonate article.  Incidentally, I discovered you can also purchase Magnesium Carbonate on Amazon.  I try to avoid non-homemade things as much as possible because you just don’t know about manufacturing.  And I think we can all agree that magnesium oxide sucks.

Based on the studies linked below – we can probably all agree, magnesium chloride is absorbed and the body does something with it.  ReMag is a brand of magnesium chloride that seems to be effective.  It’s just expensive.  Same with Magnesium Glycinate.

Now here we go with our own DIY project again.

Mag Chloride Recipe

There you have it.  Add 3.14 tbsp to 8 ounces of distilled water.  Every half teaspoon of that will give you 150mg of elemental magnesium without tasting too nasty.

The RDA for magnesium is 400 mg.  Most studies with improvement from magnesium supplementation come from 600 mg + intakes.  Most Americans are deficient in magnesium due to their diet which is low in magnesium and high in calcium and sodium.  The Greenway Biotech bag actually calls for using 33 grams in a liter of water which is about 5.5 teaspoons of magnesium chloride so you can do that as well.

A dose of 600 mg is four half teaspoon doses referenced above.  If your diet has adequate magnesium by eating the foods I reference in my post here, you won’t need as much.

Mineral Interactions

Remember that all minerals interact with other minerals – some antagonistic and some synergistic.

Magnesium drives down lead.  Lead drives down magnesium. Magnesium drives down sodium.  Sodium drives down magnesium. Magnesium drives down phosphorus.  Phosphorus drives down magnesium. Magnesium drives down calcium.  Calcium drives down magnesium. Manganese drives down magnesium.

By drives down, one could conclude that it “uses up” meaning it could be a synergistic or antagonistic interaction. Either way – pay attention to these mineral interactions as you introduce magnesium in amounts that are not naturally found in modern food.

Scott, I purchase the Greenway Biotech powdered magnesium chloride that you reference in this post. I mixed it as stated on the package and took a dose of 1.5 oz. per instructions on the package. Will this dosage once a day give me the 600 mg that is needed? I have osteoporosis and trying to hold it at bay or reverse it. Thanks.Dianne

    If you mix 33 grams of magnesium chloride with 1 Liter (1000 mL of water), you’ll have 33 mg of Mag Chloride per mL. This is 8.415 mg (25.5% magnesium by weight of magnesium-chloride) of elemental magnesium per mL. One “shot” is about 44 mL of liquid. So each shot is about 370 mg of elemental magnesium. You’ll need to take about 1.62 shots to get 600 mg of elemental magnesium.

I have been making my own magnesium “oil” by using equal containers full of the water to the flakes (i.e. half cup distilled water brought to boiling point and then adding a level half cup of magnesium chloride flakes).

My question: How many milligrams of magnesium are there in a teaspoon of this solution? I’ve tried the math, but would appreciate any help here.

    Take the grams amount and divide by the end volume to get the grams per milliliter. Then you can figure out how many milliliters you’re consuming. I don’t know how dense magnesium flakes are.

Wouldn’t it be more convenient to simply mix one teaspoon (approx. 2 grams) of mg chloride powder in orange juice? That should be about 500mg elemental mg. I find it a bit of a hassle to dilute it first

    Possibly. But I like to keep my items that taste good still tasting good. And keep my stuff that tastes gross short and sweet.

Should we take it with meals or on empty stomach?

    With meals is preferred. But it works either way.

scott do you find magnesium chloride benefits in a completely different way to say glycinate or malate forms. I found chloride worked for a while, at least i thought it was, but then i took malate, and i just´felt so much better. i think they both have uses but for different areas of the body

    The malic acid may be influencing your krebs cycles in a different way. Or you may be right that it works differently. I’m still not sure about chloride – if it interferes at all with iodide use.
