For most healthy people, sodium in drinking water is not something to worry about — it’s a small fraction of your daily intake, and most bottled water sold in the UAE already contains well under 20 mg of sodium per litre, which counts as low sodium. It matters far more if you’re on a sodium-restricted diet, managing blood pressure, or choosing water for a baby or an elderly parent. The real question isn’t whether UAE water is high in sodium — it usually isn’t — but how to know what’s in the specific water your family drinks.
This guide explains how much sodium is really in drinking water, what “low sodium” means, where the trusted limits come from, and how to check the water you drink every day — including how My Desert Spring Water approaches quality for 5-gallon delivery across Dubai, Sharjah, Ajman, and Umm Al Quwain.
Is sodium in drinking water actually bad for you?
For most people, no. Sodium is an essential mineral your body needs for nerve function, muscle contraction, and fluid balance — the concern is only ever excess, and drinking water is rarely where excess comes from.
The fact most people miss: food, not water, is the main source of dietary sodium. Water containing 20 mg/L adds only about 40 mg of sodium if you drink two litres — a small share of typical daily intake. A single restaurant meal can carry well over 1,000 mg. So for a healthy adult, normal drinking water barely moves the needle.
The picture changes for specific groups, and that’s the part worth taking seriously.
When sodium in water does matter
Sodium in drinking water becomes a real consideration for certain groups — this is guidance from health authorities, not a claim about any specific product:
People on sodium-restricted diets — the US Environmental Protection Agency (EPA) lists 20 mg/L as a guidance level, and people on doctor-ordered very-low-sodium diets are advised to choose water at or below it.
People managing high blood pressure, or heart, kidney, or liver conditions — the New York State Department of Health and others advise discussing total sodium, including water, with a doctor.
Infants and young children — smaller bodies and developing kidneys are more sensitive to mineral load, so lower-sodium water is often preferred for formula and daily drinking.
Older adults — sodium intake is more closely monitored with age.
If you’re in one of these groups, the goal is simple: know what’s in your water, and keep sodium low.
What counts as "low sodium" water?
Low sodium water generally means a sodium level at or below 20 mg/L — the level health authorities cite for people watching their intake. Here’s the practical scale, with where the numbers come from:
Sodium level Range (mg/L) What it means
Low / very low ≤ 20 Recommended for sodium-conscious households; the EPA’s guidance level for very-low-sodium diets
Moderate 20 – 200 Fine for healthy people; worth noting if you’re actively restricting sodium
Higher above ~150 – 200 Some peer-reviewed studies link water in this range to raised blood pressure; taste also becomes noticeable. More common in well or softened water than in sealed bottled water
A few trusted reference points behind that table:
The US EPA treats 20 mg/L as a guidance level for very-low-sodium diets.
The World Health Organization (WHO) has not set a binding health-based limit for sodium in drinking water, but notes taste becomes noticeable around 200 mg/L.
Peer-reviewed research has associated water above roughly 150 mg/L with higher blood pressure in some studies.
The US FDA defines “very low sodium” as 35 mg or less per serving on product labels.
One important wording note: “low sodium” is not the same as “sodium-free.” Water should only be called sodium-free if it contains virtually none — otherwise the accurate term is “low” or “very low sodium.” Reputable brands hold that line, and so should you when comparing labels.
How much sodium is in bottled water in the UAE?
Most bottled water sold in the UAE is low in sodium. Independent testing of several UAE brands found the majority sat under 20 mg/L, with only an outlier brand measuring much higher (around 110 mg/L). In other words, if you’re buying established, certified bottled water, you’re most likely already drinking low-sodium water.
The catch is knowing for sure. Two bottles that both look “pure” on the front can differ in mineral content, and the way to confirm is the mineral analysis — not the marketing. So the practical takeaway for UAE households isn’t to fear sodium, it’s to choose a certified supplier that tests its water and can back up its quality.
How My Desert Spring Water approaches quality
My Desert Spring Water is a UAE 5-gallon drinking water supplier operating since 1998, purified at a plant in Al Qusais Industrial Area 5, Dubai. Rather than asking you to take quality on trust, MDS is built around independent verification:
Independently certified to HACCP, ISO 22000, and ESMA/EQM standards — the recognised food-safety and UAE conformity marks for drinking water.
Laboratory-tested water — MDS purifies and tests its water as part of its certified quality process, not as a one-off claim.
25+ years supplying UAE homes and offices across Dubai, Sharjah, Ajman, and Umm Al Quwain — a long, consistent track record in the 5-gallon delivery category.
For UAE families choosing water for children, elderly parents, or a sodium-conscious household, that combination — certification plus a long track record — is what separates a supplier you can rely on from a label that simply says “pure.”
Who should pay closest attention
Sodium in drinking water is most worth thinking about for these households:
Families with infants or young children choosing water for formula or daily drinking
Anyone advised by a doctor to limit sodium — for blood pressure, heart, or kidney reasons
Older adults monitoring dietary sodium
Offices and clinics that want a certified, reliable water supply
If that’s you, the priority is a certified, tested source — not guesswork from the front of the bottle.
How to check the sodium in your own water
Read the label’s mineral analysis — sodium is listed in mg/L, usually on the back.
Compare against 20 mg/L — at or below is low sodium; well above is worth a second look if you’re restricting intake.
Choose a certified supplier — HACCP, ISO 22000, and ESMA/EQM marks mean the water is produced and tested to recognised standards.
For well, softened, or tank water, test it — these are the sources most likely to run high, not sealed bottled water from a certified plant.

Frequently Asked Questions
Is low sodium water better for you?
For most healthy people, sodium in water isn’t a health issue either way, because water is a minor source of sodium compared with food. Low sodium water — generally at or below 20 mg/L — mainly benefits people on sodium-restricted diets or those managing blood pressure, heart, or kidney conditions, who are often advised to keep water sodium low. It is not a treatment for any condition.
How much sodium in drinking water is too much?
The US EPA lists 20 mg/L as a guidance level for people on very-low-sodium diets, and peer-reviewed studies have linked water above roughly 150 mg/L to raised blood pressure. The WHO has not set a binding health limit but notes taste becomes noticeable around 200 mg/L. Most reputable bottled water in the UAE sits well under 20 mg/L — but the surest sign is a certified supplier that tests its water.
Does bottled water in the UAE contain sodium?
Yes, nearly all bottled water contains some sodium, because it occurs naturally as water passes through rock and soil. The amount varies by brand and source. Independent testing of UAE bottled water found most brands under 20 mg/L, with an occasional outlier much higher — so choosing a certified, tested brand matters more than the name on the front.
Which bottled water has the lowest sodium in the UAE?
Sodium levels differ by brand, and the lowest options are those that publish a figure at or below 20 mg/L. Rather than relying on marketing, look for the mineral analysis and, just as importantly, recognised certifications such as HACCP, ISO 22000, and ESMA/EQM that show the water is produced and tested to proper standards.
How can I find out how much sodium is in my drinking water?
Check the mineral analysis on the label, where sodium is listed in mg/L, and compare it against the 20 mg/L guideline. Choosing a certified supplier (HACCP, ISO 22000, ESMA/EQM) gives added assurance the water is tested to standard. For well, softened, or tank water, have it tested, as these sources are the most likely to have higher sodium.
