Structured water, also called "hexagonal water" or "H3O2 (living water)," is in a unique state, existing between liquid and solid forms. Unlike regular water (H2O), it has a distinct molecular arrangement, typically forming hexagonal clusters. This organization shares similarities with water that hasn't been contaminated by human processes, such as spring or glacial water.

Dr. Gerald Pollack, professor of bioengineering at the University of Washington, suggests that structured water plays a crucial role in biological systems. [3] He says that it ensures cellular hydration due to its higher potential to absorb minerals and nutrients.

• Digestive Health Benefits: Certain minerals found in mineral water, such as magnesium sulfate and bicarbonate, may aid digestion by promoting smoother gastrointestinal function. This can help alleviate issues like constipation and indigestion [5].
• Heart Health Support: Some studies indicate that regular consumption of mineral water may help lower bad cholesterol while increasing good cholesterol, improving cardiovascular health [6].
• Taste and Variety: Mineral water often has a distinct taste due to its mineral content, making it a flavorful alternative to regular tap water.



Spring water and glacier water are popular natural hydration choices, each with distinct origins. Spring water claims to be bottled at the source from where the water flows. It's is typically clean, organic, and free from toxins.

Sourced directly underground, spring water is naturally filtered and enriched with minerals like calcium, magnesium, and potassium, influencing its taste and healthfulness.

Glacier water, on the other hand, originates from melting glaciers—massive ice formations created over time from compressed snow. Like spring water, it undergoes natural filtration through layers of ice and rock, resulting in exceptional purity, often free from contaminants.

While both are pure and mineral-rich, glacier water's high silica, calcium, and magnesium content may aid digestion and skin health. Its slight alkalinity can also help balance body acidity.

Why Is Spring or Glacier Water the Best Water to Drink?

Drinking spring or glacier water offers several advantages that make them superior choices for hydration:

• Nutrient-Rich: Both spring and glacier waters are enriched with essential minerals like calcium, magnesium, and potassium. These minerals are vital for bone health, muscle funciton and digestion.
• Purity: Naturally filtered, both spring and glacier water are free from many contaminants like pharmaceuticals. Spring water is sourced directly underground, while glacier water originates from ancient ice formations, untouched by modern pollution.
• Better Taste: The appealing taste of spring and glacier water often leads to increased water consumption, promoting better hydration.
• Environmental Benefits: Some spring and glacier water brands prioritize sustainability through practices like using recycled materials or supporting water conservation efforts, reducing their environmental impact.
• Health Benefits: The minerals in spring and glacier water contribute to overall health. Some sources of these waters are slightly alkaline, which may offer additional benefits, although more research is needed.



Distilled water is the purest type of water that is purified by boiling it, turning it into a vapor, capturing the gas, and condensing it back to a liquid state.

Although this water is safe to drink, the purification process removes all vitamins and minerals, making it lose its long-term hydrating ability as well as taste. But, you can always add essential minerals to improve its quality. Drinking water low in minerals is detrimental to your health, thus adding Mayu Essential Minerals will ensure you’re drinking nutrient-rich water.

Why Is Distilled Water the Best Water to Drink?

Distilled water is one of the healthiest water types to drink due to several benefits:

• Detoxification: Because it's so pure, distilled water might help your body remove toxins. Staying hydrated with clean water helps your body's natural cleansing process.
• Hydration: Your body can absorb distilled water easily, which can improve hydration. If you don't like the taste of mineral-rich water, distilled water is a tasteless alternative.
• Kidney Stone Prevention: Drinking distilled water might help lower your risk of getting kidney stones. This is because it can reduce the amount of calcium and sodium in your urine.
• Versatility: Distilled water isn't just for drinking. It's also used in hospitals for sterilization and in home appliances like irons and humidifiers to avoid mineral deposits.



Alkaline water is one of the healthiest water to drink as it contains minerals that help protect the body from free radicals, which are usually linked to numerous chronic diseases and inflammation [7]. It's typically sourced from areas near mineral-rich volcanos.

This water has a higher pH level (8 to 9) than regular drinking water (pH of 7), making it less acidic compared to other types. The higher pH comes from dissolved minerals like calcium, magnesium, and potassium. You should remember that alkaline water may have side effects; drinking too much of it may lower pH levels in the body, weakening the immune system and bones.

Why Is Alkaline Water the Best Water to Drink?

Alkaline water might offer several health benefits:

• Hydration: Alkaline water could hydrate you better than regular water, especially after a workout. One study showed athletes drinking alkaline water were better hydrated than those who drank regular [8].
• Digestive Relief: Alkaline water might ease heartburn. Research suggests it can help neutralize stomach acid for a short time, reducing acid reflux symptoms [9].
• Bone Strength: Drinking alkaline water regularly might help keep your bones strong, particularly for women after menopause. A study found that postmenopausal women who drank alkaline water had slightly better bone density than those who didn't [10].
• Metabolic Support: Some research suggests people who drink alkaline water might be less likely to develop metabolic syndrome [11]. This is a group of health issues that can raise your risk of heart disease and diabetes.
• Antioxidant Effects: Alkaline water is often said to act as an antioxidant because of its negative ORP (Oxidation-Reduction Potential). This might help protect your body from damage caused by oxidative stress caused by poor diet, smoking, or alcohol.



Purified water is typically tap or groundwater that has been treated to remove harmful substances like bacteria, parasites, and other impurities, making it suitable for use.

The goal of purification is to achieve a high level of purity, typically defined by a total dissolved solids (TDS) measurement of less than 10 parts per million (PPM), showing that around 99% of contaminants have been eliminated

Nowadays, this type of water is purified by various processes, including carbon filtering, microfiltration, capacitive deionization, and reverse osmosis.

The result is clean, safe drinking water that is free from the risks associated with contaminated sources. While purified water lacks some minerals found in other types of water, it's one of the healthiest options available due to its high purity levels. If you're planning to drink it—consider remineralizing it
