? Why do some people need low-sodium water

Why has low-sodium water become an important demand in Saudi Arabia?
With the rising rates of hypertension and heart disease in the region, low-sodium water has become one of the most searched-for and requested types of water. Consumers are no longer looking just for “clean water”; they want to know the sodium content in the drinking water they consume daily to ensure it does not cause fluid retention or increased blood pressure. Choosing healthy low-sodium water is not a luxury but a real necessity for large groups such as people with high blood pressure, kidney patients, athletes, and those following a low-salt diet. This article provides a comprehensive guide to help you choose the best drinking water in Saudi Arabia while understanding the role of sodium and its impact on your body.

What is sodium? And why do we need to monitor it in water?
Sodium is an essential mineral, but it is sensitive enough that it can cause high blood pressure even when consumed in small amounts by some people. The presence of sodium in water results either from water passing through salt-rich layers of the earth or from adding minerals to improve taste. However, the problem begins when a person exceeds their daily sodium requirement because the body starts to:

1. Retain fluids

2. Put pressure on vessel walls

3. Raise blood pressure

4. Strain the kidneys

Here, choosing low-sodium water becomes an essential step.

What is the sodium content in drinking water, and how do we read the label?
On any water bottle, you will find the word Sodium or the chemical symbol (Na), indicating the sodium content in the water. Reading this information is important to determine whether the water suits your health needs, especially if you aim to reduce sodium intake to protect blood pressure or kidney health.

There are internationally recognized classifications for sodium levels in drinking water:

• Less than 5 mg/L: Considered low-sodium water, ideal for those with high blood pressure or anyone wanting hydration without extra sodium.

• 5–20 mg/L: Classified as medium sodium water, suitable for daily use by healthy individuals, but it is recommended to monitor sodium intake from other dietary sources.

• More than 20 mg/L: Considered high-sodium water, and people with high blood pressure or kidney disease should be cautious when drinking it.

Understanding these classifications and monitoring the sodium levels on the label helps you make an informed, healthy decision when choosing bottled water, making sodium intake control simple and effective without worrying about its impact on your body.

Why do some people really need low-sodium water?

1. People with high blood pressure:
   Sodium increases fluid retention, which raises blood pressure. Therefore, it is recommended for hypertension patients to choose:

• Water with less than 20 mg/L sodium

• Water low in total dissolved solids (TDS)
  This is why water suitable for hypertension patients has become a major topic of research in Saudi Arabia and the Gulf countries.

2. Kidney patients:
   The kidneys regulate sodium. When they are weakened, even a slight increase becomes a burden. Low-sodium water is therefore the best choice to protect kidney function and prevent fluid retention.

3. People with leg swelling or fluid retention:
   Excess sodium = retained fluids. Over time, symptoms appear, such as swelling in the feet, fullness in the face, heaviness of the body, and sudden weight gain. Choosing healthy low-sodium water is an important part of reducing these symptoms.

4. Athletes and supplement users:
   Athletes often get high sodium from sports drinks. They need to balance this by drinking low-sodium water to maintain electrolyte balance and prevent dehydration.

5. People on low-salt diets:
   If you are living a “low-salt healthy life,” water is part of your diet, not a neutral element. Reducing sodium from all sources, including water, is important for a healthy life and achieving desired goals.

Benefits of drinking low-sodium water:

1. Reduces blood pressure: Most significant benefit, especially for those with chronic hypertension.

2. Protects kidneys: The lower the salts in water, the less stress on the kidneys.

3. Prevents fluid retention: Fluid balance improves clearly when sodium is reduced.

4. Suitable for children: Children do not need large amounts of sodium, so low-sodium water is better for them.

5. Cleaner, lighter taste: Many feel that this water is gentler on the stomach.

How to choose healthy low-sodium water:
Before buying any water bottle, follow these steps to ensure you select water suitable for your health and personal needs:

1. Read the label carefully: Check the sodium content, ideally less than 20 mg/L for low-sodium water. Monitor TDS (total dissolved solids), ideally between 50–150 mg/L for light water that is easy to absorb, providing good hydration without overloading the body with salts.

2. Choose a reliable brand: Well-known and trusted companies clearly display salt content on the label and comply with international quality standards, ensuring safe and healthy water. Relying on established brands reduces risks from unknown or unverified water sources.

3. Try several types before settling on one: Choosing the “best drinking water” is not fixed for everyone, as taste and suitability vary depending on individual needs. Trying several types helps identify the one that suits your taste and provides proper hydration, especially if you aim to reduce sodium or monitor blood pressure.

Following these steps makes choosing low-sodium water easy and reliable, giving you peace of mind as you hydrate daily.

Review and analysis of major local and international brands in Saudi Arabia:
The Saudi market offers many brands providing low-sodium water. Based on product analysis, they can be categorized as follows:

• Very low sodium (less than 5 mg/L): Ideal for hypertension patients. Brands like Arwa, Naqi, Halwa, Huna, and Ouska usually fall into this category, with sodium ranging between 1–4 mg/L.

• Low sodium (5–20 mg/L): This category includes a wide range of good options. Brands like Arwa, Nestlé Pure Life, and Al Hada usually contain sodium levels within this range, making them healthy and suitable choices.

• Caution (more than 20 mg/L): Some natural mineral waters, especially imported ones, may contain higher sodium levels. Always read the label before purchasing these types.

Integrating low-sodium water into a healthy lifestyle:
For optimal hydration and better health, make drinking low-sodium water part of your daily routine. Carry a water bottle with you everywhere—at work or on the go—to avoid reaching for sugary drinks or sodas when thirsty, which often contain high amounts of sugar and sodium.

You can also use low-sodium water in cooking, especially for soups and stews, to reduce overall sodium content in meals without affecting taste. Adopting this daily habit not only hydrates your body but also supports blood pressure control and kidney health, making it a simple and effective step toward a balanced healthy lifestyle.

Over time, low-sodium water will become your natural first choice in all situations, whether for direct drinking or cooking, enhancing your energy and health while reducing risks associated with excessive sodium.

Best drinking water in Saudi Arabia – for those seeking low-sodium water:
In Saudi Arabia, interest in low-sodium water is higher than ever, especially with the high prevalence of hypertension and heart disease. Consumers seek healthy water that provides safe hydration without adding sodium that increases health risks, making water selection part of a balanced, healthy lifestyle.

The best drinking water contains the lowest possible sodium, is free from heavy salts and contaminants, and undergoes continuous quality testing to ensure safety and suitability for daily consumption. Many consumers now compare products based on sodium concentration only, as this has become the primary factor when choosing water, especially for those with sodium-related health issues or seeking a healthy lifestyle.

Choosing low-sodium water ensures daily hydration that supports normal blood pressure, maintains heart and kidney health, and makes caring for your health a simple, effective daily habit.

Sodium levels in bottled water in Saudi Arabia:
Sodium content varies among bottled water brands in Saudi Arabia, so it is essential to read the label before selecting the right type. For example:

• Naqi Water is among the lowest in sodium, containing approximately 2 mg/L, making it an excellent choice for those seeking healthy low-sodium water, particularly suitable for hypertension patients.

• Nova Water contains about 17 mg/L sodium, still relatively low but slightly higher than some other types.

• Berain Water also contains roughly 17 mg/L sodium, suitable for most people but not the ideal choice for those seeking minimal sodium intake.

Studies analyzing various brands in the Saudi market show sodium levels generally range between 1–26 mg/L depending on the brand and source. Some types are extremely low, suitable for hypertension and kidney patients, while others contain slightly higher levels, making it essential to ensure the water you choose is below 20 mg/L if you want very low-sodium water.

The Saudi Food and Drug Authority confirms that sodium levels in most bottled waters are not concerning for the average consumer but recommends low-sodium types for people with hypertension and those following a low-salt diet.

Conclusion: Is low-sodium water necessary?
Yes, for many people, low-sodium water is an important choice for overall health and prevention of chronic problems related to sodium. It helps reduce the risk of high blood pressure, protects the kidneys from stress caused by excess salts, and prevents fluid retention, maintaining fluid balance and reducing swelling.

Additionally, low-sodium water is suitable for low-salt diets and is safe for both the elderly and children, who need healthy hydration without excess sodium.
