Essentia Water is a popular brand of bottled water, marketed as "Supercharged Ionized Alkaline Water". Proponents claim its high pH level and added electrolytes offer superior hydration and health benefits over regular water. However, the scientific community and health experts remain divided on whether these claims hold up to scrutiny. This article cuts through the marketing to examine what Essentia is, how it's made, and if the evidence supports the health hype.
The Making of Essentia: Purification and Ionization
Essentia begins its life as municipal tap water, which undergoes a proprietary three-step process to achieve its final form.
Step 1: Purification
The water is first purified through microfiltration and reverse osmosis to remove contaminants and dissolved solids, achieving 99.9% purity. This is a standard process also used for other bottled and purified waters. The result is essentially demineralized water.
Step 2: Infusion with Electrolytes
Trace amounts of electrolytes, specifically dipotassium phosphate, magnesium sulfate, and calcium chloride, are added back to the purified water. According to Essentia, this proprietary blend is included for taste and to complement the body's natural mix, aiding rehydration.
Step 3: The Ionization Process
This is the step that makes Essentia "alkaline." The water is exposed to an electrical current in a process called electrolysis, which separates water molecules into acidic and alkaline streams. The company collects the alkaline portion, which has a pH of 9.5 or higher, and bottles it. Critics, however, label this as "artificially" alkaline, as the pH is not derived from naturally occurring minerals.
The Alkaline Water Debate: Benefits vs. Scientific Evidence
While Essentia boasts a high pH and infused electrolytes, the evidence for superior health outcomes is mixed and often debated among medical professionals.
Claim: Improved Hydration
Some proponents suggest that ionized water provides better rehydration. A small, company-funded 2014 study on mildly dehydrated adults found that rehydrating with Essentia resulted in lower blood viscosity than a standard bottled water. However, other studies and medical experts caution that these results are not conclusive and the body is highly adept at maintaining its own pH balance. The average person gets sufficient hydration from regular tap water and a balanced diet.
Claim: pH Balancing
The human body has robust natural mechanisms, primarily involving the kidneys and lungs, to maintain a tightly controlled blood pH range of 7.35 to 7.45. Drinking alkaline water has a temporary and minimal effect on stomach pH, which quickly returns to its highly acidic state to aid digestion. Therefore, the idea of changing overall body pH through diet is largely considered marketing hype by many medical professionals.
The Role of Electrolytes
Essentia does contain electrolytes like sodium, potassium, and magnesium, but only in trace amounts. While important for bodily function, the quantities are often less significant than what a healthy diet provides. For most people, consuming water with small electrolyte additives is not a necessity unless engaging in strenuous, prolonged exercise.
Potential Risks and Who Should Avoid Alkaline Water
Despite being generally safe for healthy individuals, there are potential drawbacks and risks associated with drinking highly alkaline water, particularly for certain populations.
- Digestive Disruption: Excessive consumption of high-pH water can potentially interfere with the stomach's natural acidity, disrupting digestion and the absorption of nutrients.
- Kidney Strain: The kidneys work hard to maintain the body's pH balance. For individuals with kidney disease, consistently consuming alkaline water could place additional stress on these organs.
- Impact on Medication: High-pH water can potentially react with certain medications, such as proton pump inhibitors for acid reflux, altering their effectiveness.
- Metabolic Alkalosis: In rare cases, especially with high intake, consistently consuming alkaline water could lead to metabolic alkalosis, causing symptoms like confusion, tremors, and nausea.
Essentia Water vs. Regular Tap Water
Choosing between Essentia and tap water involves weighing cost, processing, and perceived benefits.
| Feature | Essentia Water | Regular Tap Water |
|---|---|---|
| Source | Municipal tap water | Local municipal sources |
| Processing | Microfiltration, reverse osmosis, electrolyte infusion, and ionization | Regulated treatment by the EPA (U.S.) |
| pH Level | 9.5 or higher (ionized) | Typically neutral (around 7), regulated by EPA standards |
| Electrolytes | Trace amounts added for taste and hydration | Varies by location; typically contains naturally occurring minerals |
| Taste | Clean and smooth | Varies depending on source and treatment |
| Antioxidants | Antioxidant properties are debated; some studies indicate potential benefit | Not specifically associated with antioxidants |
| Cost | Significantly higher | Low cost, easily accessible |
| Environmental Impact | High due to single-use plastic bottles and transportation | Lower, especially with reusable bottles |
Conclusion: Making an Informed Choice
Ultimately, whether Essentia water is "healthy" is a complex question with no single answer. For most healthy people, regular tap water provides all the hydration necessary at a fraction of the cost and environmental impact. Essentia is a highly purified and re-mineralized water that offers a consistent, smooth taste and may provide minor rehydration benefits for some athletes. However, the more dramatic health claims often lack robust scientific backing.
As with any health-related decision, it's wise to consider your specific needs and consult a healthcare provider. People with kidney disease or those on certain medications should exercise caution. For the majority of consumers, the choice comes down to personal preference for taste, budget, and environmental consciousness, rather than proven, life-changing health benefits.

Should you drink essentia water?
Your health status, budget, and environmental concerns all factor into your decision. It is generally safe for healthy individuals but not necessary.
The best choice for hydration
Pure, filtered tap water remains the most accessible, affordable, and environmentally friendly choice for daily hydration for most people.
Long-term health effects of alkaline water
Studies on the long-term effects of artificially alkaline water are limited, and no definitive evidence supports significant long-term health benefits for healthy individuals.
The scientific consensus on alkaline water
Many medical professionals and studies assert there is insufficient scientific evidence to support the dramatic health claims of alkaline water.
Essentia vs. tap water taste
Many people find Essentia's taste to be clean and smooth, which is a subjective preference over the taste of tap water, which can vary.
