Core Electrolytes and Minerals
PowerBar's 5ELECTROLYTES formula is built around a specific blend of five minerals, designed to replace those most critical for the body's fluid balance and muscle function. These are included in the formula as various mineral salts to ensure proper dissolution and bioavailability once mixed with water.
Sodium Chloride
This is a common salt, providing the sodium and chloride electrolytes. Sodium is vital for maintaining fluid balance, nerve function, and muscle contractions, while chloride works alongside it to regulate body fluid levels. Together, they are the two most abundant electrolytes lost through sweat.
Potassium Chloride
Potassium is a key electrolyte for muscle contraction, nerve signals, and regulating blood pressure. Including potassium chloride helps replenish stores of this mineral, which is also lost through sweat during prolonged exercise.
Calcium Carbonate and Phosphates
PowerBar's tablets include calcium carbonate and calcium phosphates. Calcium is well-known for its role in maintaining healthy bones, but it is also an essential electrolyte for muscle function and nerve impulse transmission. These compounds ensure calcium is part of the rehydration mix.
Magnesium Hydroxide
Magnesium plays a critical role in energy metabolism and muscle function, and its inclusion helps reduce fatigue during intense workouts. The hydroxide form is used in the tablet to provide this crucial mineral.
Acidifiers and Acidity Regulators
To create the effervescent effect and maintain a palatable taste, several acidic and alkaline agents are included in the formulation.
- Citric Acid: A common food acid that provides the tangy flavor and is primarily responsible for the fizzing reaction when the tablet is dropped in water.
- Sodium Carbonates: These act as acidity regulators and react with the citric acid to create the carbonation in the drink.
Humectant, Sweeteners, and Flavorings
Beyond the functional ingredients, these additives make the product enjoyable to consume.
- Sorbitol: A sugar alcohol that functions as a humectant, which helps the tablet hold moisture and maintain its form.
- Sucralose: A zero-calorie artificial sweetener used to provide sweetness without adding sugar or calories.
- Natural Flavorings: PowerBar uses natural flavors to create the various fruity tastes, such as Pink Grapefruit, Lemon Tonic, and Raspberry Pomegranate.
- Inulin: A dietary fiber that can be used as a prebiotic and texturizer.
- Starch and Maltodextrin: These are used as binders and fillers in the tablet formulation.
Colorings and Performance Additives
Certain flavors also include specific ingredients for color or an extra boost.
- Lutein: A natural colorant derived from plants, giving some flavors a yellowish tint.
- Beetroot Juice Powder: A natural food coloring agent used to provide a reddish color to flavors like Raspberry Pomegranate.
- Caffeine: Select flavors, such as Pink Grapefruit and Lemon Tonic, are fortified with caffeine to enhance concentration and mental performance during workouts.

A Note on Formulation Differences
It is important to remember that PowerBar may offer various electrolyte products or reformulate existing ones. While the 5ELECTROLYTES formula is prominent, always check the label of your specific product to confirm its exact ingredients, especially for special editions or different formats. Some product variations might be regional, so cross-referencing with the official PowerBar website for your area is a best practice. For example, some international versions may have slight variations in their ingredient list or caffeine content.
Conclusion
In summary, the ingredients in PowerBar electrolytes are a combination of the five key minerals—sodium, potassium, chloride, calcium, and magnesium—supported by acidifiers for the fizz, natural flavorings for taste, and a zero-calorie sweetener, sucralose. Some versions also add caffeine for a performance boost. This zero-calorie, zero-sugar formula is designed to be a straightforward hydration solution for athletes who need to replenish minerals lost during training and competition without adding extra carbohydrates. Understanding this ingredient list can help you make an informed decision about your hydration strategy, especially concerning mineral intake and any sensitivities to additives like caffeine or sweeteners. For long or intense efforts, an athlete may need to consider adding carbohydrates alongside their electrolyte intake.
