Choosing the best water to drink still raises many questions, especially given the countless options available on the market. The most important point in every case is that the water is safe to drink, meaning it is free of microorganisms, heavy metals, and contaminants that could compromise health. More than following trends, the priority should always be the source's safety and quality. Among the different types of water, we can find:
Mineral water: This type of water stands out because it contains minerals that are important to the body, such as calcium and magnesium, which play fundamental roles in bone and muscle health. Since the body cannot produce these nutrients on its own, they must be obtained through food—and mineral water can be a supplementary source. It is considered a healthy and safe option.
Distilled water: It can be used in emergencies when there is no access to safe drinking water. It is produced by boiling water and condensing the vapor, resulting in a very pure liquid without natural minerals. For this reason, it is not recommended for daily consumption, as it can cause imbalances and affect dental and bone health over the long term.
Alkaline water: It has a higher pH than ordinary water, between 8 and 9.5. It is associated with potential benefits such as neutralizing acids in the body and antioxidant action that combats free radicals. Although promoted as healthier, there is no scientific consensus that it is better than traditional drinking water.
Ozonated water: This type of water undergoes treatment with ozone, a gas with strong oxidizing power that eliminates microorganisms and impurities. It is often promoted as having additional health benefits, such as detoxifying the body or strengthening the immune system, but to date there is no solid scientific evidence supporting these effects beyond its purification function.
What Does Science Say About the Best Type of Water for Health?
Science emphasizes that there is no “miracle” water that outperforms all others. The most important thing is to ensure potability: the water must be free of microorganisms, heavy metals, and chemical contaminants. Filtered water, mineral water, or treated tap water provides good hydration and helps the body as long as it is safe. Studies indicate that minerals such as calcium and magnesium found in mineral water can benefit bones and the heart, especially for people whose diets contain little of these nutrients.
As for “special waters,” such as alkaline or ozonated water, there is no proof that they have effects superior to those of ordinary water. The higher pH of alkaline water does not significantly alter the body's balance, which is regulated naturally. Ozonated water ensures microbiological safety but offers no additional nutritional advantages.
In fact, what is essential for health is staying hydrated with safe water, regardless of its type or marketing claims.
