What are the potential side effects of drinking too much mineral water?
We found no official limit or warning list for drinking "too much" mineral water. The practical issues are sodium and total mineral content, which vary a lot by brand, plus acidity for teeth in sparkling and flavored versions. Read the label, and ask a doctor if you have kidney disease or limit salt.

Is it bad to drink a lot of mineral water?
For most people, no official body gives a daily cap for mineral water. We searched NHS, FDA and ADA pages and found no list of side effects tied to normal amounts, so we do not repeat unsourced claims. What can matter is what is in your particular bottle.
How many minerals are in mineral water?
In the U.S., FDA lets water be called mineral water if it has at least 250 ppm total dissolved solids (TDS) and no minerals added. Below 500 ppm the label must say low mineral content, and above 1,500 ppm it must say high mineral content. A high mineral label is a cue to look at calcium, magnesium and sodium on the analysis.
Can mineral water raise your sodium intake?
It can, depending on the brand. NHS advises adults to have no more than 6 g of salt a day and says too much salt can raise blood pressure. If you limit salt, check the sodium line on the label of your mineral water, particularly if you drink several liters a day.
Does sparkling mineral water harm teeth?
The American Dental Association says sparkling water has a higher acid level, but plain sparkling water affected enamel about as much as regular water in a study of donated teeth. Citrus-flavored waters often have higher acid levels and raise the risk of enamel damage, and sweetened sparkling water counts as a sugary drink. It names plain fluoridated water as the best beverage for teeth.
Other things people report
Many people say fizzy water makes them feel bloated or gassy. We found no official source for this, so treat it as personal tolerance: switch to still mineral water if it bothers you.
Who should ask a doctor?
- People with kidney disease or kidney stones
- People on a low-salt diet or with high blood pressure
- Anyone told to limit fluids or certain minerals
Rotate brands and read the analysis rather than drinking one high-mineral water all day.
People also ask
Can you drink mineral water every day?
Yes, for most people. Check sodium and mineral content on the label, and ask a doctor if you have kidney problems or follow a salt-restricted diet.
What makes water count as mineral water?
In the U.S., at least 250 ppm total dissolved solids and no added minerals (FDA 21 CFR 165.110).
Is sparkling mineral water bad for you?
Plain sparkling water is much gentler on teeth than sugary drinks, according to the ADA. Flavored or sweetened versions carry more risk.
