We all know that water is critical for keeping our bodies functioning properly as it makes up 60% of the human body, and every cell, tissue, muscle, and system requires water to run effectively. Thus, it goes without saying that staying hydrated is essential for supporting our organs.

Most people need eight glasses of water per day, but this will vary depending on their lifestyle choices and how active a person is. And with so many different water types, it may be overwhelming to know which one is the best—as not all water is equal. Different types of water vary in nutritional benefits and caloric intake, so let’s take a closer look at which is the healthiest and best water to drink.

1. Best Overall: Structured Water

2. Most Convenient and Economical: Tap Water

3. Best Mineral Enrichment: Mineral Water

4. Most Pristine Source: Spring or Glacier Water

5. Purest, Contaminant-Free Form: Distilled Water

6. Best pH Balancing and Alkalizing Properties: Alkaline Water

7. Most High-Quality Filtration and Impurity Removal: Purified Water

Which Water Is the Healthiest to Drink?

When it comes to the healthies water to drink, we first need to discuss the seven different types of water and the pros and cons of each type of drinking water.

1. Structured Water

Structured water, also called hexagonal water, is water with a structure that has been altered to form a hexagonal molecule cluster. It's believed that highly structured water, also known as H3O2 living water, shares similarities with water that has been uncontaminated by human processes.


  • Molecules are charged, so they hold energy and recharge and hydrate the body better than ordinary water
  • Long-lasting hydration

Why Is Structured Water the Best Water to Drink?

To understand why structured water is the healthiest water to drink, here is a short comparison between unstructured and H3O2 structured water.

Structured Water

  • Has higher alkalinity levels
  • Water molecules are more easily absorbed in the cells, making it better for hydration
  • Structured water is soft and more energized

Unstructured Water

  • Has a balanced pH of 7
  • Water molecules shape may not be as effective for cell absorption and may cause dehydration
  • The body isn't gaining energy from water

2. Tap Water

Tap water goes through various purification methods with purifying agents such as chlorine and Ozone before it makes it to your tap. Although these purifying agents are useful for removing bacteria, pathogens, and contaminants and making tap water drinkable, these also strip the water from nutrients.

When it comes to the question does tap water have electrolytes, the answer may vary, depending on how many purification processes are done. It is generally considered to contain electrolytes and dissolved minerals, but the best course of action is to add essential mineral drops to your tap water to ensure you get its mineral-rich benefits.


  • Purified
  • Contains dissolved minerals, or electrolytes
  • Cheap and readily available
  • No plastic bottles needed, which is more eco-friendly


  • Might lack nutrients
  • Distinct odor or taste in certain areas may be unappealing
  • Could contain harmful compounds, like microplastics and chlorine

Enrich Your Water With Essential Minerals

Enrich your filtered water with 75 essential minerals and different microelements, ensuring you drink healthy, remineralized water.

3. Mineral Water

Mineral water is abundant in essential minerals like sulfur, magnesium, and calcium, and comes from underground sources, i.e., protected underground mineral springs. These essential minerals give this type of water a characteristic salty taste.

The most important mineral water benefits are that it supplies the body with electrolytes necessary for hydration, lowers blood pressure, and works wonders for our muscles and bones.

The recommended mineral content in drinking water is at least 250 parts per million of mineral solvents.


  • High mineral content lowers blood pressure, boosts muscle growth, and improves bone density


  • Some brands have high levels of sodium
  • Is a more costly option

4. Spring or Glacier Water

Spring or glacier water is bottled water that claims to be bottled at the source from where the water flows—either a glacier or a spring. This water is typically clean, organic, free from any treatment or toxins, and high in minerals.

If you are wondering about what is the difference between spring water and purified water, the answer is simple—spring water is naturally filtered underground, while purified water undergoes filtration and purification processes to remove contaminants and impurities.


  • Comes straight from the source, so it's less likely to contain contaminants
  • Contains good levels of essential minerals
  • Refreshing taste


  • Could still contain contaminants like metals, nitrates, chlorine, and other unwanted elements

5. Distilled Water

Distilled water is any water that has been purified by boiling the water until it turns into a vapor, capturing the gas, and condensing it back to a liquid state.

Is distilled water safe to drink? Yes. It undergoes purification processes that remove contaminants like sulfur and sodium. When it comes to the question of can you drink distilled water every day, the answer is not that simple. Though it is safe to drink, the purification of distilled water removes all vitamins and minerals, making it lose its long-term hydrating ability as well as taste.

However, you can always add essential minerals in the form of drops to distilled water to improve its quality.


  • Good option if your tap water contains chemicals or pollutants


  • No vitamins and minerals, which could negatively affect your health through mineral leaching

6. Alkaline Water

Alkaline water has a pH of 8 or 9, which is higher than normal tap water with a neutral pH of 7. Alkaline water is one of the healthiest water to drink as it contains properties that may even help protect the body from free radicals, which are usually linked to numerous chronic diseases and inflammation. It is also believed that it helps in more effective oxygen distribution throughout the body.

However, it is important to keep in mind that alkaline water may have side effects—consuming too much alkaline water may lower pH levels in the body, which can result in the weakening of the immune system and bones.


  • May hydrate the body better than regular bottled or tap water
  • May help protect the body from free radicals
  • May help distribute oxygen more effectively in the body


  • More research is needed to confirm its health benefits
  • Could change stomach acid levels, which could cause discomfort for some
  • Could lower pH levels in the body

7. Purified Water

Purified water is typically tap or groundwater that has been treated to remove harmful substances like bacteria and parasites, and other impurities, making it suitable for use. This type of water is nowadays purified by various processes, including carbon filtering, microfiltration, capacitive deionization, and reverse osmosis.

Purified water is a safe option if water sources in your area are contaminated. However, purification strips the water of minerals and electrolytes that our bodies need, thus it's best to remineralize it or add electrolyte drops for optimum and safe hydration.


  • A good option if your primary water sources are contaminated


  • Doesn't contain minerals or electrolytes the body needs

How to Choose the Right Water for You

When choosing the right water for you, the most important thing to take into consideration is the composition of water, i.e., that all elements and minerals act synergistically. Here are some questions to ask yourself before making the decision.

  • What does the water taste like? Do I like the taste?
  • Does it contain necessary essential minerals and electrolytes?
  • How much is it going to cost monthly/yearly?
  • Is it easy and convenient for me to drink?

Balancing the Pros and Cons

There are pros and cons for each type of water, so let's sum it up.

  • Tap water is the most convenient and cost-effective type of water to drink, however, it may contain harmful chemicals and pollutants.
  • Mineral, structured, and pure spring water are some of the healthiest water you can drink because they're clean and contain all the essential minerals your body needs.
  • Filtered water removes contaminants but might also remove essential minerals. However, there is the option of adding essential minerals and electrolytes back into your drinking water.

Having taken everything into consideration, it is safe to say that the most important thing is that you're drinking enough healthy water and keeping your body hydrated. Opt for the type that suits your lifestyle and tastes the best to you, and be sure to add essential minerals and electrolytes if necessary.
