Water and minerals:

Dietary minerals are the chemical elements required by living organisms, other than the four elements carbon, hydrogen, nitrogen, and oxygen that are present in nearly all organic molecules. The term "mineral" is archaic, since the intent is to describe simply the less common elements in the diet. Some are heavier than the four just mentioned, including several metals, which often occur as ions in the body. Some dietitians recommend that these be supplied from foods in which they occur naturally, or at least as complex compounds, or sometimes even from natural inorganic sources (such as calcium carbonate from ground oyster shells). Some minerals are absorbed much more readily in the ionic forms found in such sources. On the other hand, minerals are often artificially added to the diet as supplements; the most famous is likely iodine in iodized salt which prevents goiter.
Macrominerals
Many elements are essential in relative quantity; they are usually called "bulk minerals". Some are structural, but many play a role as electrolytes. Elements with recommended dietary allowance (RDA) greater than 200 mg/day are, in alphabetical order (with informal or folk-medicine perspectives in parentheses):
• Calcium, a common electrolyte, but also needed structurally (for muscle and digestive system health, bone strength, some forms neutralize acidity, may help clear toxins, provides signaling ions for nerve and membrane functions)
• Chlorine as chloride ions; very common electrolyte; see sodium, below
• Magnesium, required for processing ATP and related reactions (builds bone, causes strong peristalsis, increases flexibility, increases alkalinity)
• Phosphorus, required component of bones; essential for energy processing Potassium, a very common electrolyte (heart and nerve health)
• Sodium, a very common electrolyte; not generally found in dietary supplements, despite being needed in large quantities, because the ion is very common in food: typically as sodium chloride, or common salt. Excessive sodium consumption can deplete calcium and magnesium leading to high blood pressure and osteoporosis.
• Sulfur, for three essential amino acids and therefore many proteins (skin, hair, nails, liver, and pancreas). Sulfur is not consumed alone, but in the form of sulfur-containing amino acids

Mineral water is water from a mineral spring containing various minerals such as salts and sulfur compounds. Mineral water can be "sparkling".
IT is true that minerals are essential for the human body, no one can dispute this. They assist in controlling bone growth, regulating fluids, normalizing nerve and muscle functions, metabolic functions, growth of connective tissues, and much more.

Nevertheless, a misconception that we obtain minerals from drinking water is just that a misconception. First of all what is water in its purest form? It is H2O. Two molecules of hydrogen and one molecule of oxygen. There are no minerals included in this molecular make-up of water. The main source of minerals is always from our food and diets, and supplements, not from drinking water.
Which means you should probably watch out for water products that claim that they contain only the good (healthy minerals) in the water. Like some of the vitamin waters on the market today. There is no water purification method selective enough to leave you only the “good stuff.” “Most of the good the stuff” meaning besides calcium and magnesium, they also leave fluorides, arsenic, hard metals, radioactive materials, bacteria, viruses, chemicals, and pharmaceutical drugs. Let us not forget the fact that many natural minerals found in water are actually toxic and radioactive in nature and are known to cause cancer. In this era of pollution where water contains much more disease-causing contaminants than beneficial minerals, it makes sense that the water we drink should be pure and as clean as possible.

Eating healthy and including a wide variety of good vegetable and fruits (along with supplements) everyday is a good way to ensure that you have all the beneficial organic minerals necessary to stay healthy. Also, many reports come out that supplements don’t help that much and that most are excreted from the body.
According to many recent news and reports, most tap and well water in the U.S. is not that safe for drinking due to heavy industrial and environmental pollution. There is a great deal of toxins in the water we are drinking from municipal water systems, well, lakes, rivers, and unfortunately even glaciers, as air pollution is subsequently polluting the glaciers (which by the way contain 75% of the worlds 3% fresh water supplies). Only 3% of the water on earth is fresh water, the rest is salt water and unfit for consumption in its present state. There are methods available to clean that water but once again it becomes for all intents and purposes distilled water.


Increased human activities in manufacturing, agriculture, etc, are generating toxic bacteria, chemicals, and heavy metals in our natural water supplies. People get sick from this all the time after long term exposure. Unfortunately, that is the price we are paying for increased productivity levels. Even some brands of bottled water have been found to contain some level of contamination in addition to plastic chemicals leaching from the bottle.


Even if some of the minerals or vitamins from the water do make there way into your body most of them are too large to pass through your cells and be absorbed on a molecular level. So consider this. If you have the option of drinking water that is free of any chemicals, bacteria, viruses, metals, contaminants, and pollution that can adversely affect your overall health what is your choice going to be. Argue over whether a very tiny amount of vitamins and/or minerals may be reaching your cells that is contained in your drinking water? The other option take measures to completely eliminate all that filth and garbage from your drinking water, eat more fruits, vegetables; eat less processed foods, get a little exercise, and even take a good multi vitamin and live a healthier life. The fact is any way you cut it, that you can easily get the vitamins you need from food, and vitamins. But prolonged exposure to harmful chemicals and pollutants is going to take its toll on your health


A good water filtration system installed in your home is the only way to proactively monitor and ensure the quality and safety of your drinking water. Reverse osmosis water purification systems can remove 90-99% of all contaminants from city and well water to deliver healthy drinking water for you and your family. Another very good option but one less well known is an atmospheric water generator. Atmospheric water generators not only deliver 99.9% pure drinking water, but they are a sustainable source of water, meaning that if your water supply is some how disrupted, polluted, or contaminated you have the ability using the hydrologic cycle to harvest water from the air on a daily basis.
