Reviewed 2 times · Methodology v3.1 (updated 8 Oct 2026) — what changed

This protein supplement is formulated for adults and provides a blend of whey proteins. The primary concerns are the presence of artificial flavors and sucralose (INS 955), an intense artificial sweetener. While generally recognized as safe for consumption within acceptable daily intake limits, some individuals may prefer to limit artificial sweeteners. The product also contains carrageenan (INS 407), a thickener that has been associated with gastrointestinal inflammation in some studies, particularly in its degraded form, though food-grade carrageenan is regulated. Overall, it is suitable for healthy adults seeking a protein supplement, but those sensitive to artificial sweeteners or carrageenan should exercise caution.

Adult protein supplement with artificial flavors and sucralose sweetener

This adult protein supplement contains a blend of whey proteins, artificial flavors, and sucralose as a sweetener. While providing a good protein source, the presence of artificial flavors and sucralose may be a concern for individuals who prefer to avoid synthetic additives. It also includes carrageenan, a thickener that some studies link to gastrointestinal issues, though food-grade carrageenan is considered safe by regulators.

Okay for: Healthy adults seeking protein supplementation

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.
