4 min read

Vapor distillation is a purification method dating back centuries, effectively removing contaminants by simulating the Earth's hydrologic cycle. This intensive process leads many to wonder: is vapor distilled water safe to drink, and what are its nutritional implications for a healthy nutrition diet?

Quick Summary

Vapor distilled water is highly pure but lacks essential minerals, making it safe for short-term drinking, but not recommended for exclusive long-term use without a balanced diet.

Key Points

Is vapor distilled water safe to drink? Yes, for short-term use, but it lacks essential minerals for long-term consumption.
Mineral Content: Distillation removes nearly all beneficial minerals, including calcium and magnesium.
Taste: The lack of dissolved minerals results in a flat, bland taste that some people find unappealing.
Contaminants: The process is highly effective at removing bacteria, viruses, heavy metals, and most chemicals.
Long-Term Strategy: If consuming regularly, ensure a balanced diet rich in mineral-dense foods to prevent deficiencies.
Best for Specific Uses: It is ideal for medical equipment like CPAP machines and household appliances like irons to prevent mineral buildup.
Hydration and Electrolytes: Because it lacks electrolytes, it's not the best choice for rehydration after intense exercise or for those with specific health conditions.

The Science Behind Vapor Distillation

To understand whether is vapor distilled water safe to drink, it is important to first understand the process. Vapor distillation, or simply distillation, is a tried-and-true method of water purification. It mimics the natural hydrologic cycle by using heat to separate water molecules from impurities. The process involves several key steps:

Boiling: Water is heated to its boiling point, turning it into steam or vapor.
Vaporization: As the steam rises, it leaves behind heavier, solid contaminants such as minerals, salts, heavy metals, and bacteria.
Compression and Condensation: The purified steam is then captured, compressed, and cooled. This process allows the vapor to condense back into pure, liquid water in a separate container.
Final Filtration: Some commercial systems may pass the condensed water through an additional activated carbon filter to remove any remaining contaminants, particularly certain volatile organic compounds with low boiling points.

This multi-stage process results in water that is exceptionally pure, containing virtually nothing but hydrogen and oxygen molecules. For this reason, it is often considered the gold standard for purity and is used in laboratories and medical settings.

Is it Safe for Daily Consumption?

For most people, drinking vapor distilled water in moderation as part of a balanced diet is perfectly safe. Occasional consumption poses no significant health risks. The primary safety benefit is its purity, as the distillation process effectively removes a broad spectrum of contaminants.

However, long-term, exclusive reliance on vapor distilled water is not recommended for a few important reasons:

Mineral Depletion: The distillation process, while great at removing bad stuff, also strips out beneficial minerals like calcium, magnesium, and potassium that are found naturally in water.
Dietary Reliance: If you rely solely on distilled water, you must get all your essential minerals from food sources. For people with varied diets rich in fruits, vegetables, and whole grains, this is less of a concern. But for those with mineral-poor diets, drinking demineralized water long-term could exacerbate a deficiency.
Electrolyte Imbalance: A key concern for the World Health Organization (WHO) is the potential for electrolyte imbalances, especially during intense physical activity or in cases of excessive sweating. Electrolytes are crucial for proper nerve and muscle function, and distilled water does not help replenish them.
Altered pH and Aggressiveness: Some sources suggest that because distilled water is so pure, it is 'aggressive' and may leach minerals from your body, including teeth and bones. This is because it lacks a buffering capacity and can become slightly acidic by absorbing carbon dioxide from the air.

The Lack of Flavor

Another common characteristic of vapor distilled water is its taste, or rather, its lack thereof. Many people describe it as bland or flat because the natural minerals that give tap and spring water their flavor are removed during distillation. This lack of palatability could potentially lead some people to drink less water, impacting their overall hydration.

Comparison with Other Water Types


Feature	Vapor Distilled Water	Spring Water	Reverse Osmosis (RO) Water
Purification Method	Boiling, evaporation, and condensation	Natural filtration through rock and soil	Pressure forces water through a semi-permeable membrane
Mineral Content	Virtually none (99.9% removed)	Naturally occurring minerals retained	Most minerals and dissolved solids removed, but some may remain; often remineralized
Contaminant Removal	Highly effective, including heavy metals and microbes	Safe, but depends on source and filtration standards; can contain some impurities	Removes most contaminants, but less effective against some volatile organic compounds than distillation
Taste	Flat and bland due to lack of minerals	Crisp and refreshing taste from natural minerals	Clean taste, can be improved by remineralization
Best For	Appliances (irons, CPAP machines), labs, occasional hydration	Everyday drinking, flavor	Consistent home drinking water, removes wider range of chemicals than basic filters

What About the 'Detoxification' Claim?

Some proponents of distilled water suggest that its purity aids in body detoxification. While staying adequately hydrated is essential for flushing toxins, there is no scientific evidence to support the idea that distilled water provides a superior 'detox' effect compared to other clean water sources. The body's detoxification processes rely on the liver and kidneys, and sufficient hydration with any safe water is what supports these organs effectively.

How to Address Mineral Concerns

If you prefer or need to drink vapor distilled water, maintaining a balanced diet is crucial. The majority of your mineral intake should come from food. You can boost your intake of essential minerals like calcium, magnesium, and potassium by consuming a variety of whole foods:

Calcium: Dairy products, leafy greens (kale, spinach), fortified cereals, and nuts.
Magnesium: Seeds, nuts, whole grains, beans, and dark chocolate.
Potassium: Bananas, sweet potatoes, spinach, and avocados.

Alternatively, you can consider other water purification methods, such as reverse osmosis, which sometimes add minerals back into the water, or simply stick to natural spring or high-quality filtered tap water for daily consumption.

Conclusion

So, is vapor distilled water safe to drink? The answer is a qualified yes. It is exceptionally pure and safe for short-term or occasional use, especially if your local tap water quality is questionable. However, relying exclusively on it for long-term hydration can lead to a deficiency in essential minerals if your diet isn't sufficiently balanced. For most people, consuming water with a healthy mineral content is beneficial and often more palatable. The key is to make an informed choice based on your individual dietary habits, health status, and water quality needs.

Frequently Asked Questions

Distilled water is safe to use for mixing baby formula, but it is important to remember that it is not sterile and must be boiled for infants under four months old to kill any remaining microbes. Always consult a healthcare provider before using it for an infant.

Some research and experts suggest that demineralized water is more 'aggressive' and can pull minerals from the body to achieve balance. However, this is largely a concern for those with poor diets who rely on it exclusively, as most minerals are absorbed from food.

Vapor distilled water has a flat or bland taste because the minerals that contribute to flavor are removed during the distillation process. This is in contrast to spring water, which retains a crisp taste from its natural mineral content.

Yes, vapor distilled water is a specific type of purified water. 'Purified water' is a broader term that can be produced by various methods like reverse osmosis or deionization, which may or may not remove all minerals. Vapor distillation removes nearly 99.9% of dissolved solids.

Yes, vapor distilled water can be used for cooking, and its purity ensures no added contaminants interfere with flavors. However, cooking with it can also remove up to 60% of the minerals in foods like meat and vegetables.

The main benefit is the absence of contaminants, making it a very pure hydration source. However, claims of detoxification are not scientifically proven. For a healthy individual, the health benefits are minimal compared to other safe drinking water sources, as essential minerals are removed.

If you wish to add minerals back into distilled water, you can use commercially available mineral drops, add a pinch of high-quality sea salt, or combine it with mineral-rich foods in your diet. However, creating a balanced mineral profile can be complex.
