Dissecting the Core Components
The ingredient list for Great Value drink enhancers varies slightly by flavor, but a few core components remain constant across the lineup. These ingredients create the foundation for the product's function and flavor profile.
- Water: The primary base for the liquid concentrate.
- Citric Acid: A weak organic acid, naturally found in citrus fruits, that provides the tart or sour flavor and acts as a preservative to extend shelf life.
- Propylene Glycol: A synthetic organic compound used as a humectant and a solvent for flavorings and colorings, helping to maintain the product's consistency.
- Natural Flavor: This catch-all term, regulated by the FDA, describes flavoring components derived from natural sources, such as fruits, vegetables, or spices, to impart a specific taste.
The Sweeteners: Sucralose and Acesulfame Potassium
The zero-calorie sweetness of these drink enhancers is primarily due to a combination of two artificial sweeteners: sucralose and acesulfame potassium.
- Sucralose: This artificial sweetener is about 600 times sweeter than sugar and is made by chlorinating sucrose. It is heat-stable and adds zero calories. While regulatory bodies generally recognize it as safe, some studies have raised concerns about its long-term effects on gut health and metabolism.
- Acesulfame Potassium (Ace-K): A calorie-free sugar substitute approximately 200 times sweeter than sugar. It is often used in combination with sucralose, as it can have a slight bitter aftertaste when used alone, which is masked by blending. It is also heat-stable and excreted unchanged by the body.
Preservatives and Functional Additives
To ensure product stability and safety, several preservatives and other functional additives are included.
- Potassium Sorbate & Sodium Benzoate: These are common preservatives used to prevent the growth of mold, yeast, and bacteria, ensuring a long shelf life, even without refrigeration. The European Food Safety Authority (EFSA) and the U.S. FDA consider them safe for use.
- Gum Arabic & Sucrose Acetate Isobutyrate (SAIB): These function as emulsifiers and stabilizers to keep the liquid solution consistent and prevent separation of flavor oils and other ingredients.
Added Vitamins and Colorings
Some versions of Great Value drink enhancers are fortified with vitamins, while all include artificial colorings to create a visually appealing beverage.
- B Vitamins: Many flavors, particularly the fruit-based ones like Grape, Fruit Punch, and Orange Blast, are fortified with B vitamins, including Niacinamide (B3), Pyridoxine Hydrochloride (B6), and Cyanocobalamin (B12).
- Artificial Colors: These ingredients are added solely for aesthetic purposes. Examples include Red 40, Blue 1, Yellow 5 (Tartrazine), and Yellow 6, depending on the flavor.

Potential Health Considerations
While approved for consumption by regulatory bodies like the FDA, the ingredients in zero-calorie drink enhancers raise some health questions for consumers. Most concerns revolve around the long-term effects of artificial sweeteners.
- Artificial Sweeteners and the Gut Microbiome: Some studies, often in animal models, suggest that artificial sweeteners like sucralose can alter gut microbiota, which plays a critical role in digestion and overall health. A disrupted microbiome, or dysbiosis, can be linked to metabolic changes and inflammation. However, human studies have shown mixed results, and more research is needed.
- Metabolic Effects: Certain studies indicate that artificial sweeteners might affect insulin and glucose levels, particularly in individuals with pre-existing metabolic conditions or those who do not typically consume them. Chronic high consumption has been linked to increased risks of metabolic disorders.
- Impact on Cellular Detoxification: Research indicates that acesulfame potassium and sucralose may act as competitive inhibitors for P-glycoprotein (PGP), a crucial transporter for cellular detoxification and drug metabolism. This could potentially interfere with how the body processes certain medications.
- Heating Concerns for Sucralose: The use of sucralose at high temperatures, such as in baking, has been linked to potential decomposition and the formation of potentially harmful compounds. This is less of a concern for a cold-mixed drink enhancer but is relevant for general consumption knowledge.
Conclusion
Great Value drink enhancers offer a zero-calorie, sugar-free way to add flavor to water. The ingredients list, while primarily composed of water, acids, and flavors, relies heavily on artificial sweeteners like sucralose and acesulfame potassium. Functional ingredients such as preservatives, emulsifiers, and artificial colors are included for stability and appearance, with some varieties containing added B vitamins. While these ingredients are approved by regulatory agencies, ongoing research into the long-term effects of artificial sweeteners on gut health and metabolism has raised consumer questions. Ultimately, knowing what's in the product empowers consumers to make informed choices that align with their health and dietary goals.
