Unpacking the Nutritional Profile of La Croix
At first glance, La Croix appears to be a health-conscious consumer's dream. Each can contains just two ingredients: carbonated water and "natural flavor". This translates to a beverage that is free from calories, sugar, and artificial sweeteners, a significant advantage over many soft drinks. This simplicity is a major reason for its popularity among those trying to reduce sugar intake or lose weight.
The "Natural Flavors" Controversy
One of the most debated aspects of La Croix is the term "natural flavors." These flavor essences are derived from the natural oils of the fruits mentioned on the can. However, since they are not required to be disclosed, there has been speculation about their exact composition. In 2018, a lawsuit was filed alleging the use of synthetic ingredients, though an accredited lab later confirmed the ingredients were naturally derived from fruit. The FDA generally recognizes these components as safe, though some—like limonene—have only been linked to issues in male rats and not proven harmful to humans.
The Dental Health Debate: Is the Fizz Bad for Your Teeth?
Carbonated beverages, including sparkling water, contain carbonic acid, which can potentially erode tooth enamel over time. While La Croix is only mildly acidic, its potential for harm increases with frequent consumption, especially when flavored with citrus essences that lower the pH further. For comparison, however, La Croix is significantly less acidic than sugary sodas, which combine both sugar and acid to create a much more erosive effect.
To minimize risk, dentists recommend:
- Drinking sparkling water at mealtimes to leverage increased saliva production.
- Using a straw to minimize contact with teeth.
- Rinsing your mouth with plain water after consumption.
Hydration and Digestive Effects
One of the biggest questions is whether sparkling water is as hydrating as regular water. Research has consistently shown that plain, unsweetened sparkling water is just as hydrating as still water. For individuals who find plain water boring, La Croix can be a motivating way to increase overall fluid intake.
On the digestive side, the carbonation can cause bloating and gas for some individuals, which may aggravate symptoms for those with sensitive stomachs or irritable bowel syndrome (IBS). However, a small study in 2002 suggested carbonation might actually aid in relieving indigestion and constipation. This effect varies from person to person, so listening to your body is key.

Conclusion: The Verdict on La Croix
So, is La Croix healthy? In short, for most people, it is a very healthy choice, especially when used as a replacement for sugary beverages. With zero calories, no artificial sweeteners, and a hydrating effect comparable to plain water, it is a guilt-free way to enjoy a fizzy drink. The primary concern is potential dental erosion from its mild acidity, a risk that is still much lower than that posed by sodas and fruit juices. The "natural flavors" debate has not yielded any proven human health risks from its components at current consumption levels, with the FDA recognizing them as safe. For those who are sensitive to carbonation or have specific health conditions, moderation or opting for plain water is a sensible approach. Overall, La Croix can be an excellent tool for hydration and sugar reduction.
