BCAA Sour Patch Watermelon

In January 2025 the FDA revoked authorization for FD&C Red No. 3 in food and ingested drugs after evidence it caused thyroid tumors in male rats; under the Delaney Clause no additive shown to induce cancer in animals may be used. The same dye had already been banned from cosmetics and topical drugs since 1990. There is no reason to ingest a federally de-authorized colorant that provides only aesthetic value.

Dose context matters. As a trace excipient in a tablet coating or capsule, the amount is minimal and not a meaningful concern. The evidence below applies to the gram-level intakes typical of sweetened protein powders, pre-workouts, and drink mixes: a 2022 human trial (Suez et al., Cell) showed sucralose disrupts gut bacteria and worsens blood sugar control in healthy adults, and a 2023 study (Schiffman et al.) found that sucralose-6-acetate — a compound formed when sucralose is digested — was genotoxic to human cells in vitro. It remains an artificial sweetener with no nutritional purpose.

Composition is proprietary and not disclosed on the label, so allergens or solvents cannot be verified. Naturally flavored alternatives are more transparent.

Broad regulatory category of flavor constituents derived from natural sources.
