Why You Hydrate Your Body with Water

We often get asked about how to use ‘Magnesium Flakes’ to make mineral drinking water and what the benefits are. Below is a summary:

Most people are dehydrated these days and don't even realise that their tissue cells are low in water as their thirst mechanism is not working properly. This can happen as we get older and also because people are trying to satisfy thirst with other beverages. However beverages like juice, milk, tea, coffee, soft drinks etc are all liquid foods and require the body to put in energy and effort to digest them, thereby creating more toxic waste products that further dehydrate tissue cells and add to their acid load. The poor kidneys then have much more work to do when there is not enough water going through the system. Caffeine drinks and soft drinks are also diuretics and will cause more dehydration. It is a big mistake to count these liquid foods as a replacement for 'water'. Nothing else does what water does in the body.

How much water do you need a day?

Water is an important structural component of skin cartilage, tissues and organs. For human beings, every part of the body is dependent on water. Our body comprises about 75% water: the brain has 85%, blood is 90%, muscles are 75%, kidney is 82% and bones are 22% water. The functions of our glands and organs will eventually deteriorate if they are not nourished with good, clean water.

The average adult loses about 2.5 litres water daily through perspiration, breathing and elimination. Symptoms of the body's deterioration begins to appear when the body loses 5% of its total water volume. In a healthy adult, this is seen as fatigue and general discomfort, whereas for an infant, it can be dehydrating. In an elderly person, a 5% water loss causes the body chemistry to become abnormal, especially if the percentage of electrolytes is overbalanced with sodium. One can usually see symptoms of aging, such as wrinkles, lethargy and even disorientation. Continuous water loss over time will speed up aging as well as increase risks of diseases.

If your body is not sufficiently hydrated, the cells will draw water from your bloodstream, which will make your heart work harder. At the same time, the kidneys cannot purify blood effectively. When this happens, some of the kidney's workload is passed on to the liver and other organs, which may cause them to be severely stressed. Additionally, you may develop a number of minor health conditions such as constipation, dry and itchy skin, acne, nosebleeds, urinary tract infection, coughs, sneezing, sinus pressure, and headaches.

If the average adult loses 2.5 litres of water per day then of course this amount needs to be replaced. More active individuals can need 3 litres or more for optimum health.

Not all water is the same.

Of course tap water as most people know by now is toxic due to the chemicals it carries such as chlorine and fluoride. Chlorine can be removed by most cheap filters or can be boiled off, but fluoride (ie. sodium silicofluoride industrial grade containing heavy metals) is insidious and persists in a more concentrated form after boiling. Most filters cannot remove fluoride because its molecules are too small. Reverse osmosis and ion exchange filters can remove most (over 90% of the fluoride).

De-mineralised water such as distilled, reverse osmosis filtered, and rain water are acidic - usually around 6pH. This kind of water travels through the body very quickly and is eliminated via the digestive system often before it has accessed the tissue cells. Sometimes people can feel the urge to urinate even hourly by drinking 2.5 to 3 litres of demineralised water daily. Of course our body is receiving valuable water this way to satisfy extreme dehydration, but the amount of work the body has to do to use the water is greater, as this acidic water will seek out electrolyte salts in the body to join with before access to the intracellular fluid happens.

Ideally we should be drinking purified and remineralised water with magnesium. This will lift the pH of water to neutral or above. Alkaline water carries more negative charge which donates vital electrons to our cellular energy production. Alkaline water can be made with electrolysis or applying a magnetic field, but without the mineral electrolytes the charge doesn't hold for very long. The metallic minerals hold the charge and make the water 'wetter'. That is, this water is received by cells more readily, particularly if magnesium is present. Magnesium inside a healthy cell is 10,000 greater in quantity than in the extracellular fluid, and potassium is even greater. The most abundant electrolyte inside cells is chloride, so cells are hungry for chloride. Sodium and calcium are more common in the extracellular fluid because they are larger molecules and can't fit into the tight spaces of the structured water that forms cell cytoplasm.


Electrolyte balance is essential for cell membranes to maintain correct charge and function properly, expelling waste products and allowing in nutrients and water via channels. As magnesium is lost under stress and not replaced, the cell membrane starts to lose the charge and becomes more permeable. This can lead to loss of too much potassium, which can cause a heart attack. As the membrane becomes compromised, some of the cytoplasm becomes de-structured, allowing in too much sodium and calcium, causing cell excitation and further dehydration because sodium steals the cell's water molecules. Loss of magnesium and dehydration leads to cramping, muscle spasms and restless legs.

You will notice some people develop swollen ankles when dehydrated. That is a sign that the kidneys are struggling due to dehydration. As water becomes scarce in cells, the hormone vasopressin is released to squeeze the blood vessels so more water is extracted and pushed into the tissue cells where mitochondria need it (together with magnesium) to make ATP energy which drives enzyme activity. Water is also pushed up to the brain this way because the brain is very water-hungry, and of course it is most critical for the brain to maintain adequate hydration. Eventually dehydration can get to the brain too, causing delirium and fainting. This squeezing of the cardiovascular system causes hypertension and a big strain on the heart muscle. By the way, the left ventricle of the heart is the muscle in the body with the most magnesium receptor sites.

To economise on water loss the kidney then holds in more sodium instead of excreting the surplus. The effect of the extra salt retention successfully holds in more water, but the side effect is that it pools in the lower extremities as swollen ankles (oedema).

Restricting all sodium consumption doesn't deal with the issue of dehydration in tissue cells, and the body needs adequate sodium to function. You will note that saline is a part of our tears, phlegm, blood plasma... all body fluids. Sodium of course should be consumed in reasonable quantity as a whole raw salt (containing the other minerals) to season food. Some people do have excess sodium and intake should be regulated - especially in the case of high blood pressure.

It is often the case that simply increasing water intake containing magnesium salts will re-balance electrolytes and bring hydration levels back to normal.

It should be noted that this small amount of magnesium is not enough to address all magnesium needs and transdermal application (our Magnesium Creams & Spritz Oil) using the large surface area of the skin (all over body) is still recommended to absorb the largest amounts of magnesium. However, magnesium salts added to water improves the hydrating quality of the water.

Recommended quantity of Magnesium Salt Flakes (food grade) to add to filtered water: 3 to 5 flakes per litre according to taste.

This will bring the water pH to neutral or above and make it more palatable. In other words, you will feel like you can actually drink more water without gagging. Also take note of your bowel movements if you over do your Magnesium Salt Flakes they can get a bit loose for a short time :- ).

There are also other Magnesium Salt Flake applications from foot soaking, bathing to magnesium mouthwash. ‘Click Here’ to learn more.
