Is Mineral Water Safe During Pregnancy? (Updated 2026 Guide)
Updated July 19, 2026
The Answer
Mineral water is generally safe during pregnancy when it comes from a reliable source and has a simple ingredient list. We reviewed 69 products: 65 received an A, while four received lower grades.
Most mineral waters we reviewed contained mineral water, carbon dioxide, or similarly simple ingredients. The main considerations are added sweeteners such as high fructose corn syrup, synthetic colors such as Red 40, and nitrate or nitrates from a potentially contaminated water source; nitrate risk depends on the source and concentration rather than the word alone.

Track your pregnancy and check what’s safe
✓ What's Safe
- • A short ingredient list centered on mineral water or carbonated mineral water
- • Water from a clearly identified, reliable commercial source
- • An unsweetened option for everyday hydration
- • A label without added colors or unnecessary flavoring ingredients
- • Mineral and sodium information when you have been advised to monitor your intake
✗ What to Avoid
- • Mineral water drinks sweetened with high fructose corn syrup for routine hydration
- • Products containing Red 40 when a simpler, dye free option is available
- • Water from an untested private well or another source with uncertain nitrate levels
- • Assuming every flavored mineral water drink is plain water without reading its label
- • Using a high sodium mineral water as your default if your clinician has told you to restrict sodium
Most Common Ingredients in Mineral Water Products
We analyzed 69 mineral water products. Here are the most common ingredients, ranked by how often they appear:
Ingredients to Watch Out For in Mineral Water
These are the most common flagged ingredients across 69 mineral water products we analyzed.
high fructose corn syrup
CAUTION
High fructose corn syrup is an added sweetener used in drinks and processed foods. Is not a known teratogen at occasional food amounts, but high added sugar intake can displace nutrients and raise gestational diabetes and metabolic concerns.
Found in 2 of 69 products (3%)
nitrate
CAUTION
Nitrate is naturally occurring nitrogen compounds found in vegetables and drinking water and used in cured meats. Is context dependent because vegetable sources are generally compatible with pregnancy while contaminated well water above nitrate/nitrite limits can cause methemoglobinemia and has observational links to adverse birth outcomes.
Found in 1 of 69 products (1%)
nitrates
CAUTION
Nitrates is naturally occurring nitrogen compounds found in vegetables and drinking water and used in cured meats. Is context dependent because vegetable sources are generally compatible with pregnancy while contaminated well water above nitrate/nitrite limits can cause methemoglobinemia and has observational links to adverse birth outcomes.
Found in 1 of 69 products (1%)
red 40
CAUTION
Red 40 is a synthetic red food dye used in processed foods, drinks, candies, and some medicines. Has limited human pregnancy data and is allowed at regulated food additive levels, but child neurobehavior concerns and high dose animal findings make frequent high dye intake worth limiting.

Your Questions Answered
Is mineral water safe during pregnancy?
Usually, yes. Plain mineral water from a reliable source is generally a straightforward hydration option, and 65 of the 69 products we reviewed received an A. Check flavored varieties carefully because some contain added sweeteners, colors, or other ingredients.
Can I drink carbonated mineral water while pregnant?
Carbonation itself does not change mineral water into an unsafe pregnancy drink based on the ingredients reviewed here. Carbonated mineral water and carbon dioxide were among the most common ingredients in this category. Choose a plain, unsweetened version when you want the simplest option.
Is flavored sparkling water okay during pregnancy?
It can be, but the ingredient list matters more than the flavor name. Some flavored waters contain only water, carbonation, and flavoring, while others add high fructose corn syrup, artificial sweeteners, preservatives, or colors. Compare labels and favor the simpler, unsweetened formulation.
Who should not drink mineral water?
Mineral water is not automatically unsuitable for a particular group, but individual mineral profiles can matter. If your clinician has asked you to limit sodium or another mineral, check the nutrition label before making it your regular drink. Water from a private well or uncertain source should also be tested for contaminants such as nitrate rather than assumed safe.
Are nitrate and nitrates in mineral water dangerous during pregnancy?
Their significance depends on the source and concentration. Vegetable nitrate exposure is not equivalent to drinking water contaminated above nitrate or nitrite limits, and observational findings do not prove that every trace exposure causes harm. Use a regulated water source, and have private well water tested rather than relying on taste or appearance.
Can I drink mineral water throughout all three trimesters?
Nothing in the reviewed category data suggests that plain mineral water requires different handling by trimester. The same label and source checks apply throughout pregnancy: choose reliable water and limit products with added sugar or unnecessary colors. Ask your clinician for individualized advice if you have been told to restrict sodium, fluids, or specific minerals.
How Do We Score Products for Pregnancy Safety?
We analyze each product's ingredients and category to flag known risks and provide cautionary notices for general category safety concerns.
A - Safe
Excellent choice! All ingredients are considered safe during pregnancy.
What to do: Use with confidence.
B - Likely Safe
Pretty much safe with very minimal risk. Some ingredients may have limited pregnancy studies, but no significant safety concerns have been identified.
What to do: Use with confidence.
C - Limit
Contains ingredients with some pregnancy considerations. Research shows these ingredients may have limited safety data, potential for minor hormonal effects, or require caution based on animal studies.
What to do: Use sparingly and consider safer alternatives when available.
D - Caution
Similar to C grade but contains multiple cautionary ingredients. The combination increases overall concern.
What to do: Try to avoid if that makes you feel better. If you've already used it, no need to panic.
F - Avoid
Contains ingredients with established risks during pregnancy. Research shows these can cause birth defects, developmental harm, or serious maternal complications.
What to do: Do not use during pregnancy. If you've already used it, don't worry - contact your OBGYN if concerned.
