The score is capped for a specific safety reason, set out below. This energy drink is formulated with multiple artificial additives, including artificial sweeteners and undisclosed artificial and natural flavors, which are common in ultra-processed beverages. The high caffeine content makes it unsuitable for children and sensitive individuals. While it provides some B vitamins, these do not offset the concerns associated with its highly processed nature and stimulant load.

Decode Label Analysis
Contains high levels of caffeine, which can cause adverse effects such as increased heart rate, anxiety, and sleep disturbances, especially in children, pregnant women, and individuals sensitive to stimulants.
Contains artificial sweeteners (Sucralose, Acesulfame Potassium) which contribute to the ultra-processed nature of the product and have ongoing research regarding their long-term health effects.
Contains Caramel coloring, which depending on its class (III or IV), may contain 4-methylimidazole (4-MeI), classified by IARC as a Group 2B possible human carcinogen.
Contains undisclosed 'Natural Flavors' and 'Artificial Flavors', which can be a concern for individuals with specific sensitivities or allergies to flavor compounds.
Combined Effects interactions
Caffeine
Taurine
While taurine's direct stimulant effect is debated, its combination with high levels of caffeine in energy drinks is often associated with increased risk of adverse cardiovascular and neurological effects, particularly in susceptible individuals. The synergistic effects are not fully understood but warrant caution.
Sucralose
Acesulfame Potassium
These artificial sweeteners are often combined to achieve a more sugar-like taste profile and reduce the amount of each individual sweetener needed. However, their combined use contributes to the overall artificiality of the product and raises cumulative concerns regarding potential metabolic and gut microbiome impacts, which are still under research.

About this analysis: Based on declared label information and available evidence. Decode Label does not independently laboratory-test products, and a score is not a regulatory determination or medical advice.
Disclaimer: Safety scores are Decode Label-generated assessments based on publicly available regulatory data (FSSAI, WHO, EFSA, IARC) and peer-reviewed research. They are not a substitute for professional medical advice, and they are not a regulatory determination, a laboratory safety certification or a medical diagnosis. Ingredient safety can vary by individual health conditions, concentration, and usage context. Decode Label is an independent information service and scores every brand by the same rules. No brand pays for or influences its score. Our founder also founded the personal-care brand Botani Bestie (see our story); its products are scored exactly like everyone else's. Data limitations: This assessment is based on the information declared on the product label and the evidence sources above — Decode Label does not independently laboratory-test this product. Ingredient concentrations, sourcing and manufacturing can vary between batches and are not always disclosed. A finding that is not shown here means it was not identified from the available label information, not that it has been ruled out.
