Best Bottled Water for Baby Formula: What Parents Should Know
Choosing the right water for infant formula matters — babies' kidneys are still developing, and small amounts of sodium, minerals or fluoride matter more than they do for adults. This guide summarises what public-health bodies and pediatric groups recommend, so you can bring informed questions to your child's pediatrician.
Medical disclaimer: This article is for general information only and is not medical, pediatric or nutrition advice. Always follow your pediatrician's guidance on water for infants, formula preparation and any water choices related to a medical condition. For infants under 6 months, consult a healthcare provider before switching water sources.

Can you use bottled water for baby formula?
Yes — most bottled waters can be used to prepare infant formula, provided they are low in sodium, low in overall minerals and either boiled or from a source certified safe for infants. The US CDC and the NHS in the UK both state that bottled water is an acceptable option when tap water is unavailable or unsafe.
What kind of bottled water is best for baby formula?
Look for bottled water that is: low sodium (under 20 mg/L, ideally under 10), low sulphate (under 250 mg/L), low nitrate (under 10 mg/L), and low overall mineral content (TDS under 500 mg/L). Avoid strongly mineralised waters like Gerolsteiner, San Pellegrino, Vichy Catalan or Contrex for formula preparation.
Low sodium water
Sodium adds up quickly in a formula-fed infant's diet. Choose waters well under 20 mg/L sodium. Good options include Deer Park, Poland Spring, Evian (6.5 mg/L), Icelandic Glacial and Voss Still. See the low-sodium bottled water guide.
Low mineral water
Low-mineral (low-TDS) waters place the least load on developing kidneys. Purified brands like Aquafina and Smartwater sit near 10 mg/L TDS; spring brands like Poland Spring and Deer Park are also low. Full list: low mineral bottled water.
Fluoride considerations
The American Academy of Pediatrics and US FDA recommend using water with fluoride below 0.7 mg/L when preparing formula for infants under 6 months, to reduce the risk of enamel fluorosis. Most bottled waters (Evian, Fiji, Deer Park, Poland Spring, Aquafina) are well below this threshold. Waters labelled "with added fluoride" or "nursery water" are the exception — check the label.
Distilled water vs spring water vs mineral water
- Distilled water — near-zero minerals and fluoride, sterile from the process. Widely recommended for formula preparation.
- Purified water (Aquafina, Smartwater) — very low TDS and low fluoride. Safe and commonly used for formula.
- Spring water (Deer Park, Poland Spring, Evian) — acceptable if sodium and mineral levels are low; check the label.
- Mineral water (Gerolsteiner, San Pellegrino, Vittel) — not recommended for regular formula preparation due to high mineral load.
When to boil water
The NHS and WHO recommend boiling water — bottled or tap — and cooling it to about 70°C before mixing with powdered formula, because powdered formula is not sterile. Ready-to-feed and liquid concentrate formulas do not require this step. Never re-boil bottled water repeatedly, and don't use sparkling or flavoured water.
Questions to ask your pediatrician
- Is our local tap water safe for formula, or should we use bottled?
- Do you recommend a specific brand of bottled or nursery water?
- Does my baby need supplemental fluoride, and if so from what age?
- Should I boil the water, and until what age?
- Are there any local advisories about lead, nitrate or bacteria I should know about?
Spanish FAQ / Preguntas frecuentes en español
¿Puedo usar agua embotellada para preparar la fórmula de mi bebé? Sí, siempre que sea baja en sodio y minerales, y siga las instrucciones de la fórmula y de su pediatra.
¿Qué tipo de agua embotellada es mejor? Agua destilada o purificada con bajo TDS (menos de 500 mg/L) y bajo sodio (menos de 20 mg/L). Evite aguas minerales fuertes como Gerolsteiner o San Pellegrino.
¿Debo hervir el agua embotellada? Para fórmula en polvo, la OMS recomienda hervir el agua y enfriarla a unos 70°C antes de mezclarla, porque la fórmula en polvo no es estéril.

Frequently asked questions
What is the best bottled water for baby formula?
A low-sodium, low-mineral water such as distilled water, Aquafina, Smartwater, Poland Spring, Deer Park or Evian. Always confirm your choice with your pediatrician.
Can I use Fiji water for baby formula?
Fiji is low in sodium (18 mg/L) and moderate in minerals, so it is usable in a pinch, but lower-mineral waters are generally preferred for daily formula preparation.
Is distilled water safe for babies?
Yes — distilled water is widely recommended for formula preparation because it is sterile and mineral-free. Follow the formula label's mixing instructions.
Do I need to boil bottled water for formula?
For powdered formula, WHO and NHS guidance says yes: boil the water and cool it to about 70°C before mixing, because powdered formula is not sterile. Ready-to-feed formula does not need boiled water.
Should baby formula water contain fluoride?
For infants under 6 months, use water with fluoride below 0.7 mg/L to reduce fluorosis risk. Most bottled waters are well below this level, but check the label for 'added fluoride' or 'nursery water' products.
