A few years ago we (my wife & I) supplemented with magnesium chloride from the Zechstein deposits – an ancient seabed. I then started making magnesium citrate & later magnesium malate. The one problem with these compounds (salts) is that after awhile a white deposit would start to form – probably the salts coming out of solution – still alright to drink. A long time later I came across another salt of magnesium which solves this problem & which is more desirable – magnesium citrate malate.
Later I will show you how to make this supplement, as well as giving more information about magnesium.

From an Article:
Magnesium must be bound to something else for the body to ingest and digest it. So, look for these different kinds of combinations. Follow the recommended doses on the particular formulation you choose. I find magnesium citrate, at the top of my list, to be the best place to start overall:

Magnesium citrate:
Magnesium citrate is the most popular supplement form. It’s relatively inexpensive and easily absorbed in the body. Know that citrate also acts as a mild laxative. That being said, you may want to get your magnesium from a different source if you suffer from diarrhea or loose bowels.
Magnesium taurate:
Magnesium taurate is easily absorbed and often used for heart health. It guards the heart from damage caused by heart attacks. It also prevents arrhythmia (abnormal heartbeats), which may lead to blood clots or cardiac arrest.
Magnesium malate:
Magnesium malate is a good choice for people with fibromyalgia-chronic fatigue syndrome (FM-CFS). Malate or malic acid is a natural constituent found in fruits, such as apples. It’s also a key metabolite in every cell in the body.In fact, malic acid plays a critical role in energy production and synthesis of ATP — the body’s batteries that store metabolic energy.
Magnesium chloride:
Magnesium chloride is essentially a salt or electrolyte. Instead of a sodium atom bound to a chlorine atom (salt), it has two chlorine atoms bound to magnesium.It’s only 12 percent elemental magnesium. But as a salt, it’s rapidly absorbed from the GI system into blood and tissues. It also functions as an electrolyte (electrolytes are essential to our metabolism) and helps excrete toxins from tissues in the body. The chloride helps kidney function, but without the sodium. This supplement can be taken in oral form or you can use it in the form of bath salts for a warm, detoxifying soak.
*Citrate is quicker to be absorbed and used by the body, whereas malate stays in your system longer.

Magnesium Citrate-Malate: [You can buy this – why not make it?!]
Magnesium Citrate-Malate by Dr. Paul Lohmann® is a fully reacted Mineral and a new and innovative ingredient for food supplements. The combination of Magnesium with two organic acids, citric acid and malic acid, leads to a Mineral Salt with excellent solubility. Citric acid and malic acid are part of the human metabolism and therefore easy to metabolize.

The free-flowing and non-hygroscopic powder is clear soluble and stable in solution. The Magnesium content is similar to other organic Magnesium Salts, but the performance in liquid application forms is much better. Comparable products are not stable in solution over storage time or even insoluble.
The original taste is more pleasant compared to other Magnesium sources and can be easily masked. Magnesium Citrate-Malate is especially designed by Dr. Paul Lohmann® for the use in high concentrated liquid ready-to-drink food supplements.

From another source:
Magnesium (citrate/malate):
Magnesium (citrate/malate) is a highly bioavailable magnesium chelate, which supports the metabolism and utilixation of carbohydrates, amino acids and fats for energy.

My Summary of Key Points:
*excellent solubility & storage stable
*more pleasant taste
*a chelate
*highly bioavailable

My DIY:
magnesium oxide 7.35 g iHerb (US) – free shipping over about NZ$60
I buy NOW 8oz. 227g NZ$20.20 (7.35 g = 65 c)
citric acid 10 g New Zealand The Sourcery 1kg NZ$9 (10g = 9 c)
malic acid 15 g New Zealand The Sourcery 5kg NZ$100 (15g = 30c)
water-distilled 300 ml (or rainwater)
Apart from the water, the cost is $1.04 for 20×221.5mg doses. So, 5.2 c/dose.
Citric acid is readily available. Malic acid should be available online.
1) Weigh each powder & put in a pot. Add the water.
2) Heat above 55 Celsius, stirring now & then.
3) When clarified, let it cool & place in a jar – keep in a cupboard.
magnesium content: 24.3/40.3×7.35 g = 4.43 g = 4,430 mg
1 dose = 15 ml (1T) contains 15/300×4430 mg Mg = 221.5 mg Mg
My wife & I take 2 doses/day = 443 mg. The jar lasts for 5 days.
*Currently I have doubled the quantity made. It keeps well for 10 days.
You may get a slight white deposit in the jar-ignore it.

Here is a product online:
Magnesium CitraMate – Thorne:
US$16 90 caps So, approx NZ27c/cap
Magnesium (Citrate) 55mg
Magnesium (Dimagnesium Malate) 80mg
Take 1 capsule one to three times daily
*So, 3 caps contains 405 mg Mg & costs about NZ78c compared with NZ10.4c DIY

What I found online:
MgCM is a mixed salt consisting of magnesium cations and citrate and malate anions, and with a magnesium content of 12–15%.
MgCM is proposed to be used in food supplements that are intended to provide up to 300–540 mg/day magnesium.
The human studies provided demonstrate that magnesium from MgCM is bioavailable.
The Panel notes that at the proposed maximum use levels of MgCM, the existing tolerable upper intake level for magnesium in nutritional supplements, water, or added to food and beverages (250 mg/day) is exceeded.
*Not so from what I have discovered.
The product is stable throughout its proposed shelf life.
citrate:malate = 1.28 to 1.65

Nutrient Metabolism Support: Supports the metabolism and utilisation of macronutrients, energy production, and the proper functioning of important enzymatic and physiological functions.
Overall Health: Magnesium activates the enzymes necessary for a number of physiological functions, including neuromuscular contraction and cardiovascular function.
Cellular Energy Production: Magnesium is necessary for the metabolism of carbohydrates, amino acids and fats, as well as for energy production and the utilization of calcium, phosphorus, sodium and potassium.*

Pure Encapsulations Magnesium citrate-malate offers magnesium bound to both the highly researched Kreb’s cycle intermediates citrate and malate. For this form, citrate and malate are bound together and then the whole complex is bound to magnesium. Some studies suggest that this chelate may be better absorbed than the citrate form.

Bone Health: *I will give details later at my health website on “Biological Transmutations”
Quote – Prof Louis Kervran: “The cases of decalcification, much more frequent nowadays, are due in part to our ‘industrial’ modern diet which is deficient in magnesium. White bread & white salt are preferred for business & aesthetic reasons, to the detriment of our health.”
