Today, I’ll examine the acidity of popular sparkling water brand, LaCroix.
No sodium, no sweetener, no calories- that’s LaCroix for you. Yet, it’s been recently noted that it’s quite acidic. Made sense given it’s carbonated which could introduce some acids. Being naturally curious, I decided to test this out using a pH meter.
How Did I Test?
I used tap water as a control. Usually, the pH range of tap water lies between 6.5 and 8.5. My tap water had a value of 8.18- quite on the alkaline side. I’m based in the San Francisco Bay Area, known for its high water quality.
I compared this tap water with LaCroix’s berry flavor.

The Result:
Interesting results right here! LaCroix indicated a pH of around 3.5. This means LaCroix is indeed acidic, more so than tap water. See the comparison table below:
Solution | pH value |
---|---|
Tap Water | 8.18 |
LaCroix (Berry flavor) | 3.5 |
But, what does that mean?
The lower pH denotes higher acidity. This result indeed validates users’ views about LaCroix’s acidity. However, I’m yet to determine if this is beneficial or harmful in any way.
It may be advisable to brush your teeth after consuming acidic beverages. Though LaCroix lacks sweeteners or calories, the acidic nature of this drink might warrant good oral hygiene habits.
It’s clear though that LaCroix water is comparatively more acidic than tap water. Will that stop me from drinking lots of it? No way! But I might be more diligent about brushing my teeth after having a LaCroix in the evening.
