Lab-grade distilled water, also known as deionized water or purified water, is produced through a process of distillation or other purification methods to remove impurities and minerals. While it is generally safe for various laboratory applications, it is not typically recommended for drinking due to the following reasons:
Lack of Essential Minerals: Distillation and purification processes remove not only impurities but also minerals that are beneficial for human health. These minerals, such as calcium, magnesium, and potassium, are important for maintaining proper bodily functions. Drinking water that lacks these minerals may contribute to mineral deficiencies over time.
Potential for Contaminants: Although lab-grade distilled water is purified, it can still be vulnerable to contaminants if not stored properly. It can absorb substances from the environment, including gases, volatile compounds, and leached materials from storage containers. These contaminants may not be harmful in laboratory settings but could be a concern for human consumption.
Altered Taste and Effects on Hydration: Lab-grade distilled water has a flat taste due to the absence of dissolved minerals. Some people may find this taste unappealing, which can impact their drinking habits. Additionally, there is a notion that drinking distilled water may not be as effective in hydrating the body compared to water with natural mineral content.
For these reasons, it is generally recommended to drink water that contains the necessary minerals and is fit for human consumption. This includes drinking tap water that has been treated according to regulations or bottled water that meets appropriate drinking water standards.
