The Core Ingredients: A Simple List
For most LaCroix flavors, the ingredients list is refreshingly short: carbonated water and natural flavors. While this simplicity is a key part of its appeal, it also raises questions about what these “natural flavors” actually are. Unlike soda, which uses a cocktail of artificial sweeteners and preservatives, LaCroix relies on a straightforward formulation.
Carbonated Water
The base of LaCroix is plain water infused with carbon dioxide ($CO_2$) gas to create the familiar bubbles. This process is what gives the drink its characteristic effervescence. Sparkling water is known to be as hydrating as regular still water, making it an excellent calorie-free alternative to soda or juice.
The Mystery of “Natural Flavors”
This is where the ingredients in LaCroix water get more complex. According to the company, these natural flavors come from the "natural essence oils extracted from the named fruit". The FDA broadly defines 'natural flavor' as any flavoring derived from a natural source, such as a fruit, vegetable, or spice. However, the specific compounds and the exact extraction process are proprietary and not disclosed, a practice common in the beverage industry.
This lack of transparency has led to public scrutiny and even lawsuits in the past. In 2018, a class-action lawsuit alleged that LaCroix contained synthetic ingredients, a claim the company vehemently denied, stating all its essences are 100% natural. The lawsuit was ultimately withdrawn by the plaintiff. Despite the legal challenges, the mystery remains for curious consumers who want to know the exact source and makeup of the essences.
A Closer Look at the Flavoring Process
Creating the essence oils used in LaCroix involves various extraction methods. Techniques like steam distillation or cold-pressing are used to capture the aromatic and flavorful compounds from fruits and other plant materials. This process concentrates the delicate flavors into an oil that is later mixed with the carbonated water. For example, the Pamplemousse flavor (French for grapefruit) gets its distinct taste from essence oils derived directly from grapefruit.
Nutritional Profile and Health Aspects
One of the most significant selling points for LaCroix is its clean nutritional profile. Each can contains zero calories, zero sweeteners, and zero sodium. This makes it a popular choice for those watching their weight or managing conditions like diabetes. It is also vegan, gluten-free, and Non-GMO Project Verified.
Potential Health Concerns with Sparkling Water:
- Dental Erosion: The carbonic acid formed by the dissolved $CO_2$ makes sparkling water slightly more acidic than regular water. While significantly less erosive than soda, excessive consumption could potentially contribute to tooth enamel erosion over time. However, healthy saliva production helps neutralize this acidity, and drinking it with meals can minimize risk.
- Digestive Discomfort: Some individuals with sensitive digestive systems may experience bloating, gas, or heartburn from the carbonation.
Comparison: LaCroix vs. Other Sparkling Waters
LaCroix is just one of many options in a crowded market. Brands differ in their carbonation levels, flavor sources, and additional ingredients.

Common Flavor Essences
LaCroix offers a wide variety of flavors, each with its own unique aroma profile derived from natural essence oils. Here are a few examples:
- Pamplemousse: Grapefruit essence, a classic and popular choice.

Conclusion: Is LaCroix a Good Choice?
Ultimately, the ingredients in LaCroix water—carbonated water and natural fruit essences—make it a healthy, calorie-free alternative to sugary soft drinks. While the proprietary nature of the "natural flavors" leaves some questions unanswered, multiple withdrawn lawsuits and company assurances have affirmed its all-natural claims. For most people, it serves as an excellent way to stay hydrated and enjoy a flavored beverage without the drawbacks of sugar, artificial sweeteners, or sodium. As with any food or drink, moderation is key, especially for those concerned about dental health or digestive sensitivity. The choice between LaCroix and other brands often comes down to personal preference regarding flavor intensity and carbonation levels, but its simplicity is a significant benefit.
