According to a 2016 study published in the American Journal of Clinical Nutrition, sparkling water is just as hydrating as regular still water. This provides good news for those wondering, 'Does LaCroix hydrate you?' as the popular beverage can indeed contribute effectively to your daily fluid intake goals.

Quick Summary

LaCroix and other plain sparkling waters are as hydrating as regular water, counting towards daily fluid intake goals. As a zero-calorie, zero-sweetener alternative to sugary sodas, it offers a healthier choice, but carbonation may cause bloating in sensitive individuals.

Key Points

Equally Hydrating: Plain LaCroix is proven to be just as effective for hydration as still water, as the carbonation does not hinder absorption.
Healthy Alternative: With zero calories, sweeteners, and sodium, LaCroix is an excellent substitute for sugary sodas and other unhealthy beverages.
Potential for Bloating: The carbonation in LaCroix can cause gas and bloating for some individuals, particularly those with a sensitive digestive system.
Minimal Dental Risk: While slightly more acidic than still water, plain LaCroix is considered low-risk for tooth enamel erosion compared to sugary drinks.
Enhances Intake: The flavor and fizz can make it easier and more enjoyable for some people to meet their daily fluid intake goals.
Not for Intense Exercise: Still water is preferable during intense workouts, as the carbonation can lead to uncomfortable bloating.

The Science of Hydration: Does LaCroix Measure Up?

LaCroix is essentially carbonated water with natural fruit essences, and the carbonation process does not reduce its hydrating properties. The body absorbs the water in sparkling water the same way it absorbs still water, making both effective for rehydration, provided the drink is free of added sugars, artificial sweeteners, and sodium, as is the case with standard LaCroix. A study comparing the hydration levels of various beverages, including sparkling and still water, found no significant difference between them using a Beverage Hydration Index (BHI).

Benefits of Choosing LaCroix for Hydration

LaCroix can be a good option for those who find plain water unappealing, offering a flavorful, calorie-free way to increase fluid intake. This encourages water intake, serves as a healthy soda substitute, may aid digestion, and supports weight management.

Potential Drawbacks and Considerations

While generally healthy, LaCroix may cause bloating or gas in individuals with sensitive digestive systems or IBS due to carbonation. Flavored sparkling waters containing citric acid can be mildly acidic and potentially affect dental enamel over time, though significantly less so than sugary sodas.

How to Hydrate with LaCroix Effectively

To best incorporate LaCroix into your hydration routine, read the label to ensure no added sugars or additives, alternate with plain still water to mitigate potential dental effects, consider timing to avoid bloating during intense exercise, and listen to your body. LaCroix can also be used as a healthy mixer.

Conclusion

Unsweetened sparkling waters like LaCroix hydrate just as effectively as still water, offering a zero-calorie, zero-sugar, and zero-sodium alternative to sugary drinks that can help increase overall fluid intake. While carbonation may cause bloating in some, and flavored varieties have slight acidity, for most, the benefits outweigh potential minor risks. The most important factor for hydration is consistently drinking enough fluids.
