Our read on this product

The drink relies on sucralose, a high-intensity artificial sweetener that has raised concerns regarding gut health and metabolic signaling. While it contains beneficial B-vitamins like Niacinamide and B12, these are offset by the inclusion of chemical preservatives such as sorbic acid and benzoic acid. With a health score of 35/100, the product lacks real nutritional density, relying entirely on stimulants and synthetic additives.

Best for

This drink is intended for healthy adults looking for a temporary boost in alertness and energy during exercise or work.

Approach with care

Individuals sensitive to high caffeine intake, artificial sweeteners like sucralose, or those with underlying digestive or cardiovascular conditions should avoid this product.
