Our read on this product

With a health score of 45/100, this beverage is categorized as unhealthy due to the inclusion of phosphoric acid and caramel E150d. While it contains zero sugar and zero calories, the use of aspartame and acesulfame K raises concerns regarding artificial sweetener sensitivity and potential metabolic impacts. Phosphoric acid specifically has been linked to potential risks concerning long-term bone density when consumed frequently. Ultimately, the product is a highly processed industrial formulation.

Best for

This beverage is intended for individuals seeking a calorie-free drink who also need to avoid caffeine for sleep or anxiety-related reasons.

Approach with care

Individuals sensitive to artificial sweeteners like aspartame or those concerned with bone health and dental enamel erosion should avoid this product.

Ingredients to watch

Caramel E150d: Watch out
Phosphoric Acid: Watch out
Sweeteners (Aspartame, Acesulfame K): Watch out
Neutral

Carbonated Water

Water infused with carbon dioxide under pressure to create fizz. It serves as the primary base for the beverage. It is neutral in health impact but provides the expected mouthfeel.

Watch out

Caramel E150d

A food coloring used to provide the dark signature color of Coca-Cola. It is a synthetic ammonia-sulfite caramel, which some studies have linked to potential safety concerns at high doses, though it is FDA-approved.

Watch out

Phosphoric Acid

Acts as an acidulant to provide a sharp, tangy flavor and helps preserve the product. Frequent consumption is linked to reduced bone mineral density and potential tooth enamel erosion.

Watch out

Sweeteners (Aspartame, Acesulfame K)

High-intensity artificial sweeteners that provide sweetness without calories. While they allow for a sugar-free label, some users report sensitivity or dislike the chemical aftertaste.

Neutral

Potassium Citrate

Used as a buffering agent to regulate acidity and balance the tanginess of the phosphoric acid. It is generally recognized as safe and serves a functional role in flavor stability.

Neutral

Flavorings

Proprietary natural extracts that give the beverage its characteristic taste. The exact composition is a trade secret.
