What is Purified Water?

Is Purified Water Good For You

Purified water is water that has undergone a purification process to remove impurities and contaminants, such as minerals, bacteria, viruses, and chemicals. This process can be done through various methods, such as distillation, reverse osmosis, or carbon filtration. 

Purified water is often sold in bottles or containers, and it can also be found in public water systems. While purified water does not contain any significant amounts of minerals or other trace elements found in natural spring water, it is generally considered safe for consumption and can be a good option for individuals looking for clean, safe drinking water.

Nutrition Facts of Purified Water

Purified water is a calorie-free and nutrient-free beverage. As a result, there are no significant nutritional facts to report. However, purified water is an essential component of a healthy lifestyle, as it helps to keep the body hydrated and supports various bodily functions. 

Additionally, purified water does not contain any added sugars, artificial sweeteners, or other additives that can contribute to poor health outcomes.

Pros and Cons

Here are some potential pros and cons of purified water:


  1. Clean and safe: Purified water has undergone a rigorous purification process, which removes impurities and contaminants, making it a clean and safe option for consumption.
  2. Consistent quality: Purified water has a consistent quality, as it is subject to strict regulatory standards and quality control measures.
  3. Versatility: Purified water can be used for a variety of purposes, including drinking, cooking, and cleaning.


  1. Lacks minerals: Purified water typically lacks the minerals and other trace elements found in natural spring water, which can be important for some individuals’ health.
  2. Environmental impact: The production and transportation of purified water can have a negative impact on the environment, contributing to plastic waste and greenhouse gas emissions.
  3. Cost: Purified water can be more expensive than tap water, which can make it less accessible to individuals with limited financial resources.

Overall, while purified water is generally considered safe and clean, it may not be the best option for everyone. It is important to consider your individual needs and preferences when choosing a water source.

Health Benefits of Purified Water

Purified water is an essential component of a healthy lifestyle, as it helps to keep the body hydrated and supports various bodily functions. While there are no specific health benefits associated with purified water consumption, staying hydrated is critical for maintaining optimal health.

Some potential benefits of adequate hydration include:

  1. Improved physical performance: Staying hydrated can improve physical performance, as it helps to regulate body temperature, lubricate joints, and deliver oxygen to muscles.
  2. Better cognitive function: Dehydration can impair cognitive function, and adequate hydration has been linked to improved mood, concentration, and overall cognitive performance.
  3. Weight management: Drinking water can help with weight management by reducing appetite and increasing feelings of fullness.

What Do Medical Experts Say About Purified Water?

Medical experts generally agree that drinking purified water is a healthy choice as it helps to keep the body hydrated and supports overall health. However, there are few specific quotes or studies on the topic as purified water is simply water that has been treated to remove impurities and contaminants.

According to the study titled as ‘The Human Right to Water’ published in the Journal of Water Policy explained that, “Purified water is water that has been mechanically filtered or processed to remove impurities and make it suitable for use. Purified water may meet the requirements for human consumption and other uses and is used for various purposes in medicine.”

The study in the Journal of Current Environmental Health Reports recommends drinking water to support oral health, stating that “Drinking fluoridated water is an effective and inexpensive way to prevent tooth decay. It has been 70 years since Grand Rapids, Michigan, became the first city in the world to fluoridate its drinking water.”

In general, medical experts recommend drinking plenty of water, including purified water, to support overall health and hydration.

Scientific Studies on Purified Water

As purified water is simply water that has been treated to remove impurities and contaminants, there are no specific studies that examine the health benefits of drinking purified water in comparison to other types of water. 

However, there are studies on the benefits of drinking water in general, which would also apply to purified water.

Here are five studies on the health benefits of drinking water:

  1. Drinking Water and Weight Loss: A Systematic Review and Meta-Analysis. This study found that drinking water before meals can help with weight loss. It suggests that drinking 500 mL of water before meals can help people eat fewer calories and lose weight.
  2. Water intake on skin health and function: A systematic review. This study reviewed the literature about the water intake on skin health and found that increased water intake can improve skin hydration and thickness.
  3. Hydration and Cognitive Function: A Review. This study found that mild dehydration can impair cognitive function, including memory, attention, and reaction time. It suggests that maintaining adequate hydration levels may be important for cognitive function.
  4. The connection between drinking water and sleep quality in individuals with insomnia. This study found that increasing water intake can improve sleep quality in individuals with insomnia. It suggests that maintaining adequate hydration levels may be important for sleep quality.
  5. Water, hydration and health. This review article examines the role of water in the body and the health benefits of adequate hydration. It suggests that maintaining adequate hydration levels can support various body functions, including regulating body temperature, promoting digestion, and supporting cognitive function.

What do Health experts say about Purified Water?

As purified water is a basic form of water, there is no specific expert commentary or literature that focuses solely on purified water. However, health experts generally recommend drinking enough water and staying hydrated for overall health benefits.

According to the Centers for Disease Control and Prevention (CDC), drinking water can help maintain body temperature, lubricate joints, protect the spinal cord, and remove waste from the body.

The CDC recommends drinking at least eight 8-ounce glasses of water per day or more depending on age, sex, weight, and activity level.

Who Should Avoid Purified Water?

There is no specific group of people who should avoid purified water. Purified water is generally safe and recommended for all individuals to stay hydrated and maintain good health. 

However, there are some exceptions where certain types of purified water may not be suitable for consumption. For example, individuals with weakened immune systems may need to avoid drinking water from certain sources, such as well water, if it has not been properly treated to remove harmful contaminants.

It is important to note that some purified water products may contain added minerals, such as sodium or magnesium, which may not be suitable for individuals with certain medical conditions. For example, individuals with high blood pressure may need to limit their sodium intake.

Alternatives to Purified Water

  1. Spring water: Spring water is collected from natural springs, which are typically located in remote and pristine areas. It is often filtered and bottled directly at the source, making it a popular alternative to purified water.
  2. Alkaline water: Alkaline water has a higher pH level than tap or purified water, typically between 7.5 and 9.5. Some people believe that drinking alkaline water can help balance the body’s pH levels and provide additional health benefits.
  3. Mineral water: Mineral water is sourced from underground springs and contains a range of minerals and trace elements, such as calcium, magnesium, and potassium. Some people prefer mineral water for its perceived health benefits and natural taste.
