Water 101 – Know what you are drinking for optimum health

Water has been a hot topic for years with experts frequently swaying between tap and bottled varieties as the healthiest option. For most of us, as long as we are drinking 8-10 glasses of water a day, where we get the water from is often not a consideration. But what if you can enhance your health by avoiding specific types of water? Here, we explain the different types and what impact they can have on your body.


Throughout nature, we can witness the devastating effects of dehydration. Dehydrated leaves crinkle and shrink before dying, humans, lose muscle mass, gain wrinkles and become prone to illness when they are dehydrated for a prolonged period of time. Water regulates body temperature, aids digestion, protects vital organs, cushions joints, facilitates cellular communication, transports nutrients to the cells, and removes waste, including lactic acid (the primary cause of exercise-related muscle soreness). It does wonderful things for our skin, cognitive function and vitality.

Government health standards ensure that the water that reaches our homes adheres to strict standards and compliance making it a suitable choice for drinking. UK tap water is renowned for being the cleanest in the world owing to the treatment and disinfection process. Unfortunately, this means that most of the beneficial minerals in water are often removed at the same time.

However, it is important to remember that tap water is purified with chlorine and often has fluoride added to it. There is also evidence that medications including strands of antibiotics, antidepressants and contraceptives are finding their way into drinking water and as a result, into our bodies.

The parts per million (ppm) content of water is measured by TDS (Total Dissolved Solids). Anything with a rating of over 500ppm is considered unsuitable for consumption. Most tap water ranges between 150-420ppm, but we recommend using a high-quality filter to reduce this if you are going to consume tap water.


In theory, drinking spring water is health promoting. But as is the case with all types of drinking water, the water source is the key. True spring water is captured from a natural, mountain, or artesian spring. When harvested properly, spring water is sparkling clean.

This form of water is rich in natural minerals and generally has a much better taste than water from the tap, a bottle or with added minerals. On top of that, spring water comes from deep within the Earth, often from reservoirs that are extremely old when humans were not capable of distributing chemicals into the environment. This water is untouched by these toxic byproducts and is, therefore the cleanest and healthiest source for the human body.

Sadly, there are few natural sources of spring water easily accessible to the public. It is important that if you drink natural spring water you check that the local area is free of contamination, something that may not be immediately obvious to the human eye. Be wary of spring water labels on many plastic bottles and mainstream water brands. Very often, this is not truly spring water and is another form of treated tap water.

Although bottled water has enjoyed a good reputation for a long time, it may not be as good as we think. Plastic bottles contain chemicals that are detrimental to the human body and the endocrine system in particular. We can experience further problems if plastic bottles are left in the sun, in heated areas or left to stand for prolonged periods of time. Our lack of visibility and traceability on the water bottle journey makes it harder for us to know how good it is for us.

Combined with the fact that a large percentage of bottled water (45%) starts as tap water, we may not be reaping many rewards from this little purchase.

If you are drinking bottled water on a regular basis we recommend using a glass bottle or purchasing your own reusable one and filling it with natural spring water or a well-filtered water for the most benefits.

Viv drinks water from either Voss or Tau depending on whether she is drinking water on its own or whether she is mixing it with a supplement. A slightly acidic water will dissolve powders much more quickly whereas an alkalized water will have a little sweeter taste.

Our favourite brand of portable water bottles is bkr; they stock a range of beautiful bottles in various sizes that will have you constantly reaching to take another sip.

The human body is healthiest when it is in an alkaline state (over 7.4). Processed food and bad diets can lead to an acidic bodily state, leaving us prone to disease and deterioration.

Natural water has a pH of 7. Anything above seven is considered alkalized water. Alkaline water is rich in alkalizing compounds, including calcium, silica, potassium, magnesium, and bicarbonate.

Some research on the effects of alkaline water has indicated that it can be beneficial for gut health and lower glycation levels. It may also be a better source of hydration for athletes. However, there remains to be much more in-depth research into this and it is true that making your body more alkaline may not always be a smart idea. People with kidney conditions may trigger a build-up of minerals in their body while an overly alkalized body could cause a condition called metabolic alkalosis.

Should you want to drink alkalized water, then you can invest in a water ioniser or water supplements although these should be sourced from clean environments and locations. Another simple way to get an alkaline water fix is to have a glass of water and fresh lemon in the morning. (This genius little recipe is great for detox and weight loss too.)

Distillation is the process in which water is boiled, evaporated and the vapour condensed. Distilled water is free of dissolved minerals and, because of this, has the unique property of being able to absorb toxic substances from the body and eliminate them actively. Studies validate the benefits of drinking distilled water when one is seeking to cleanse or detoxify the system for short periods of time (a few weeks at a time). However, prolonged use of distilled water after this can be problematic for health.

For example, distilled water is an active absorber, and when it comes into contact with air, it absorbs carbon dioxide, making it acidic. The more distilled water a person drinks, the higher the body acidity becomes. An acidic body as we have already mentioned is linked to cellular deterioration and disease.

The distillation process also deprives the body of essential minerals that contribute to overall good health. A lack of minerals can cause irregularities in the body and has been linked to cardiovascular problems.

There are contradictory and confusing opinions on what is the fundamentally best water to drink online and in the media. The important aspect of health is to be aware of what you are putting in your body and making educated choices. The state our body is in will have a large impact on what we should be nurturing it with and as time goes by our physical needs will change and vary.

At Rejuva HQ our ethos is to ingest as many natural, organic, clean and free from metals products as we can access. Moderation is the key to success in any health regime and being hydrated is far more important than being dehydrated because you can not get to a specific brand of water.

Take note of the changes your body and mind experience when you change aspects of your diet and lifestyle. Doing this will give you a solid indicator as to whether something is working with you or against you. Raise your awareness of the quality of your water by purchasing a TDS machine and quality filters to use at home for the safest options and ensure that if your filter is removing minerals from water, that you reabsorb them by eating the right food.
