What’s in Water?

You may be a little confused about what’s in your water, and if so, you’re not the only one.

1. All water is made up of hydrogen and oxygen.

This is a scientific fact! Water is H2O, and ideally, this simple bond would be all that your water is.

  • However, water tends to pick up trace elements of just about everything it touches, due to its nature, and therefore there’s always more in your water than just oxygen and hydrogen. This is why water can become polluted by something like plastic floating in it; when water passes over something enough times, it starts to pick up the chemicals or substances from that item. Chemicals in plastic, for example, can leach into water very quickly.

2. Some bottled water contains salt, potassium, or magnesium.

Especially if you’re looking at mineral water, you’re probably going to find bottled water that contains one or more of these minerals. This is not a bad thing, especially if you’re trying to improve your overall mineral intake every day. However, it can be damaging for some people who already have too much of one or more of these minerals in their diets. If you’re trying to avoid certain minerals, take care when drinking mineral water.

  • Children and babies should never be given mineral water because they may suffer from mineral poisoning in some instances.

3. Other brands contain chloride or sodium bicarbonate. 

If you’re looking at artesian water, you’re probably going to buy something that contains one or more of these substances. Again, this is not necessarily a bad thing, but it can be less than ideal depending on what you’re looking for in your water. If you want straight-up water that doesn’t have something like this in it, stick to regular old bottled water.

4. Still others contain calcium. 

Mineral water and artesian water both may contain calcium, but even some “normal” bottled waters may be treated with additional calcium. Just like the other potential substances you may find in your water, whether or not you want to drink this is entirely up to you.

5. Bottled water contains no fat.

If the bottle of water you’re drinking has fat in it, then there’s definitely something else in there besides water! You should never have to worry about fat content in any bottled water, no matter where it comes from or who bottles it. Only sparkling waters that contain sugar and flavorings may, in some instances, also have a fat content—but even this is very rare. Chances are good that if you’re drinking something with fat, it’s not water at all.

6. Bottled water contains no sugar. 

Again, this is not true of every type of bottled water, but it’s true of the good ones. If you like to drink flavored bottled waters or sparkling waters, then you’re probably going to be getting some sugar in your water. Even if your water is flavored “naturally,” that doesn’t mean it’s free from sugar—it just means it’s free from certain types of sugar. Pay close attention to the label on waters like this for best results, and remember that if you can’t easily pinpoint where a “natural flavor” comes from, then you may just want to skip it entirely and go for something a little closer to nature.

7. There are zero calories in bottled water. 

Just like fats and sugars, you should not ever see calories in true bottled water. Of course, once again, this is not true of all flavored or sparkling waters. If your water has any calories—even just a few—it’s simply not as good for you as regular bottled water would be, and it’s probably better if you just skip it and go for something healthier. However, if you want to treat yourself to a flavored water every now and then, there’s no reason not to. Just pick one that uses natural sweeteners rather than chemicals and contains as few calories as possible.


As you can see, there are a lot of things that may be present in your water. However, it’s important to remember that these substances and ingredients are not present in all waters, and you should always pay attention to the label on the water you’re drinking to find out for sure just what you’re dealing with.

If you have any concerns, be sure to talk to your doctor to find out more information as well. Your doctor will be able to tell you exactly what you need for your specific and individual health and wellbeing. If you’re lacking in any certain vitamins or minerals, your doctor can let you know which type of water is best for you to drink in order to build up what you need, too.

But are all bottled waters the same, or do some contain different nutrients and calories? Whether you’re drinking water out of the tap or you’re buying a specialty brand of water, these types of water are not all the same. You can get a lot of different things from different types of water, and even the brand name alone is sometimes enough to make a difference. For example, artesian water from one brand may have added calcium while another brand doesn’t have much calcium but is packed with sodium bicarbonate instead.

In the end, the most effective way to choose which type of water is right for you is to think about what your body needs most. From there, you can choose the water that contains the proper amount of that mineral or nutrient. Just remember that, no matter which water you choose, your water should always contain absolutely zero calories!
