This article delves into the nutritional profile of Crystal Light, its potential benefits and drawbacks, and its suitability for a keto lifestyle.
What is Crystal Light?
Crystal Light beverages contain little to no calories and zero sugar and fat per serving. According to the FDA, a ½ packet of the beverage contains approximately 5 calories, 0 grams of total fat, 0 mg of cholesterol, 35 mg of sodium, 0 g of total carbs, 0 g of dietary fiber, 0 g of sugar and 0 g of protein.
Ingredients
Crystal Light contains a number of ingredients, including:
- Sucralose: An artificial sweetener.
- Aspartame: An artificial sweetener.

It’s important to note that the Food and Drug Administration’s (FDA) FoodData Central considers all of these ingredients as “generally recognized as safe,” or GRAS.
The Keto Diet: An Overview
The ketogenic diet, or keto diet, is a low-carbohydrate, high-fat diet. When following a keto diet, sugar is a carbohydrate. The primary goal of the keto diet is to shift the body's metabolism from using glucose (from carbohydrates) to using ketones (from fat) as its main energy source. This metabolic state, known as ketosis, is achieved by drastically reducing carbohydrate intake and increasing fat consumption. Benefits of the keto diet are weight loss, reduction in blood sugar fluctuations and insulin levels, lower hunger levels, and an increase in "good" cholesterol.

Crystal Light and Keto: The Connection
Given that Crystal Light has no sugar, little to no carbs, and doesn’t raise blood sugar, it would seem fitting for a keto diet. On the surface, the macros look impressive.
Potential Benefits
- Low in Calories and Carbs: Crystal Light is very low in calories and carbohydrates, which aligns with the primary goal of the keto diet. For every 8-ounce glass of a Crystal Light drink from the classic line, you get about 5 calories and no sugar, according to FoodData Central.
- Sweetness without Sugar: Crystal Light offers a sweet taste without the use of sugar, thanks to artificial sweeteners like aspartame and sucralose. This can help satisfy sweet cravings without derailing ketosis.
- Hydration Aid: Crystal Light’s refreshing flavor can make the process of drinking water a lot more appealing for many people. Crystal Light may also help you stay hydrated. This can help people manage their weight because thirst is often misconstrued as hunger, according to the Cleveland Clinic.
Potential Drawbacks
Despite the potential benefits, there are several concerns regarding the consumption of Crystal Light on a keto diet:
- Artificial Sweeteners: Crystal Light relies on artificial sweeteners like aspartame and sucralose to achieve its sweet taste. While these sweeteners are approved by the FDA, they have been a subject of controversy. Some studies suggest potential negative effects of artificial sweeteners, including headaches and depressive symptoms, according to studies published in JAMA Network Open and Frontiers in Nutrition. Recent studies have found that artificial sweeteners, such as sucralose and aspartame, could damage the healthy bacteria in your intestines, might be more addictive, and could increase sugar cravings.
- Artificial Colors: Crystal Light contains artificial colors such as yellow 5, red 40, and blue 1. Some people may have allergic reactions to color additives such as yellow 5, which can cause itchiness and hives, although it is rare. Artificial food dyes have been associated with allergic reactions; behavioral problems in children, including attention deficit disorder (ADD) and attention deficit hyperactivity disorder (ADHD); neurobehavioral disorders; and autoimmune disorders, according to a study published in May 2024 in the International Journal of Environmental Research and Public Health, although more research is needed.
- Compensatory Eating: Some experts claim that drinking (or eating) artificial sweeteners may make some people think that it gives them more room in their diet for high-calorie foods. This would cancel out any calorie reduction and could lead to a calorie surplus, says Harvard Health Publishing. Crystal Light is also so sweet that your palate may get used to the super sweetness, causing you to crave sweet foods,” Young adds.
- Phenylketonuria Warning: Some Crystal Light flavors have a warning for phenylketonurics that the drink mix contains phenylalanine. People with phenylketonuria aren’t able to properly digest phenylalanine, aspartame can be highly toxic for them.
Special Considerations
- Diabetes: People with diabetes can have most sugar substitutes, including aspartame, sucralose, and stevia. But sucralose in foods has been linked to reduced insulin sensitivity, per research published in September 2018 in Nutrients.
- Kidney Disease: “Crystal Light is considered to be an appropriate beverage for those with kidney disease,” Mussatto says.
- Pregnancy: Beverages like Crystal Light may fit the bill. They’re hydrating, have no sugar, and contain very few calories.
Alternatives to Crystal Light
There are plenty of alternatives to Crystal Light that are free from artificial sweeteners, flavors, coloring, and preservatives. If you’re looking to replace Crystal Light, seek out products that also provide nutrients, such as vitamin C, probiotics, and electrolyte minerals. Some alternatives include:
- Homemade Flavored Water: You can make homemade flavored water by combining fresh fruits such as raspberries, peaches, lemons, pineapple, and oranges, and some erythritol simple syrup in a glass or jug and stir.
- Green or black tea are other keto-friendly drink options.
