December 14, 2025 •

2 min read

MiO, the zero-calorie liquid water enhancer, is a popular way to flavor plain water, but its ingredient list contains more than just flavor. Understanding what goes into each concentrated drop is key to knowing what you are consuming, from artificial sweeteners to coloring agents.

Quick Summary

MiO liquid water enhancers are primarily made with water, citric acid, artificial sweeteners like sucralose and acesulfame potassium, natural and artificial flavors, preservatives, and food colorings. Specific varieties also contain caffeine, B vitamins, or electrolytes.

Key Points

Core Ingredients: MiO is made with a water base, combined with artificial sweeteners, food acids, natural and artificial flavors, preservatives, and artificial colors.
Artificial Sweeteners: The sweet taste comes from sucralose and acesulfame potassium, which are zero-calorie sugar substitutes used in most varieties.
Functional Additives: Specialty MiO products like Energy, Vitamins, and Sport contain functional ingredients such as caffeine, B-vitamins, and electrolytes.
Preservatives and Stabilizers: Ingredients like potassium sorbate and propylene glycol are used to extend shelf life and maintain the liquid's consistency.
Artificial Colors: Artificial dyes, such as Red 40, Blue 1, and Yellow 5, are added for visual appeal, though some concerns about their health effects have been raised.
Stevia Option: Certain flavors within the MiO Vitamins line are naturally sweetened with stevia leaf extract instead of artificial sweeteners.

Core Ingredients of MiO

MiO's base formula includes water, citric acid, and artificial sweeteners to provide flavor and a concentrated liquid foundation.

Artificial Sweeteners and Flavoring

Most MiO products achieve their sugar-free, zero-calorie profile using high-intensity artificial sweeteners like Sucralose and Acesulfame Potassium (Ace-K). Some MiO Vitamins varieties utilize stevia leaf extract for natural sweetness. These sweeteners mimic the taste of sugar without adding calories.

Acids, Preservatives, and Stabilizers

Citric and malic acids add a tangy flavor and preserve MiO by lowering pH. Potassium sorbate and sodium benzoate prevent microbial growth. Stabilizers such as Gum Arabic and Sucrose Acetate Isobutyrate (SAIB) ensure product consistency. Propylene glycol acts as a flavor carrier.

The Role of Artificial Colors

Artificial food dyes like Red 40, Blue 1, and Yellow 5 give MiO its colors, varying by flavor. While the FDA considers these dyes safe within limits, concerns about potential health effects exist.

Specialized MiO Product Lines

MiO offers different lines with added functional ingredients:

MiO Energy: Contains caffeine (around 60mg per serving), taurine, guarana extract, and ginseng extract for energy.
MiO Vitamins: Fortified with Niacin (B3), B6, and B12. Some use stevia as a sweetener.
MiO Sport / Electrolytes: Includes sodium and potassium to help replenish electrolytes.
