How we got 4.5 ShowHide
Methodology v3.1 (updated 8 Oct 2026) — what changed
This carbonated beverage relies on a blend of artificial sweeteners, including aspartame, sucralose, and acesulfame potassium. Aspartame is classified by IARC as Group 2B, 'possibly carcinogenic to humans', which is a significant concern for regular consumption. The long-term effects of sucralose and acesulfame potassium are still under research. The product also contains undisclosed flavouring substances, which limits transparency for consumers with sensitivities or allergies to specific flavour compounds. While it offers a sugar-free option, the reliance on multiple artificial sweeteners and lack of flavour transparency are notable drawbacks.

Ingredient Concerns safety database
Sources cited below may be Indian (FSSAI) or international (EU, US, WHO, IARC) — an international classification or law is evidence, not an Indian regulatory finding.
Aspartame (E951)
Aspartame contains phenylalanine and is absolutely contraindicated for people with phenylketonuria (PKU). In July 2023, IARC classified aspartame as "possibly carcinogenic to humans" (Group 2B), though JECFA maintained its ADI. People with PKU must strictly avoid it; others should consume in moderation.
Regulatory & scientific authority Source: IARC/JECFA Joint Statement July 2023; FSSAI
Aspartame: regulation, sources and other products →Sucralose (E955)
Sucralose is an approved intense sweetener with an established acceptable daily intake. The WHO (2023) advises against relying on non-sugar sweeteners for weight control, and research into long-term gut and metabolic effects is ongoing. Heating it at very high temperatures is not recommended.
Regulatory & scientific authority Source: WHO guideline on non-sugar sweeteners (2023); EFSA/JECFA acceptable daily intake
Sucralose: regulation, sources and other products →Acesulfame Potassium (E950)
Acesulfame K is an approved intense sweetener. Regulators set an acceptable daily intake and consider it safe within it, but the WHO (2023) advises against using non-sugar sweeteners to control body weight because there is no long-term benefit and possible long-term harms, and long-term research on gut and metabolic effects is still developing.
Regulatory & scientific authority Source: WHO guideline on non-sugar sweeteners (2023); EFSA/JECFA acceptable daily intake
Acesulfame Potassium: regulation, sources and other products →Flavouring Substances
Indian rules classify added flavours as natural, nature-identical (chemically synthesised copies of natural compounds) or artificial, and require the class to be declared. The label names the class, not the compounds, so a reader cannot see which substances make up the blend, or whether it carries something they avoid. This is information about transparency, not a finding of harm.

Flavouring Substances: regulation, sources and other products →Decode Label Analysis

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.
