The Sweeteners in Most MiO Products
For consumers asking, "Does MiO contain artificial sweeteners?", the answer is yes, particularly for the Original, Energy, and Sport lines. The primary non-nutritive sweeteners found in these products are sucralose and acesulfame potassium (Ace-K).
- Sucralose (Splenda): This artificial sweetener is made by modifying a sugar molecule, and it is significantly sweeter than table sugar. While the FDA has approved sucralose as generally recognized as safe (GRAS), some animal and human studies suggest it may affect blood glucose levels and insulin response.
 - Acesulfame Potassium (Ace-K): Also approved by the FDA, Acesulfame Potassium is a calorie-free sweetener often used in combination with others to create a more balanced taste. Some early studies raised questions about its safety, though the FDA has maintained its safety assessment based on extensive testing.
 
The Naturally Sweetened Alternative: MiO Vitamins
Not all MiO products rely on artificial sweeteners. The company also offers specific naturally sweetened options, primarily within its MiO Vitamins product line. These versions use stevia leaf extract, a plant-based sweetener derived from the Stevia rebaudiana plant.
- Stevia Leaf Extract: Stevia is also considered GRAS by the FDA and is often preferred by consumers looking for natural, zero-calorie sweetener alternatives. Some research has even explored its potential therapeutic benefits. To identify these products, always check the ingredient list for “stevia leaf extract”.
 
Other Common MiO Ingredients and Considerations
Beyond sweeteners, MiO products contain other additives that are worth noting:
- Artificial Colors: Many MiO flavors use artificial food dyes like Red 40, Yellow 5, and Blue 1. Concerns have been raised about these dyes, particularly regarding potential links to hyperactivity in children, though the FDA deems them safe within regulatory limits.
 - Preservatives: Preservatives such as potassium sorbate and sodium benzoate are used to extend shelf life. While also considered safe by the FDA, some individuals may have sensitivities.
 - Vitamins and Electrolytes: The MiO Vitamins, Energy, and Sport lines contain added nutrients like B vitamins, electrolytes, or caffeine.

Conclusion
So, does MiO contain artificial sweeteners? Yes, most standard MiO flavors across the Original, Energy, and Sport lines are sweetened with a combination of sucralose and acesulfame potassium. However, some options within the MiO Vitamins line are naturally sweetened with stevia leaf extract for those looking to avoid artificial alternatives. While the FDA has approved these ingredients for consumption in moderate amounts, some individuals may choose to opt for naturally sweetened MiO or water infused with whole fruits and herbs due to ongoing debates and potential sensitivities. Always reading the ingredient label is the best practice to determine the specific sweeteners in the flavor you choose.
