SucraloseSweetener
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.
ErythritolSweetener
Witkowski et al. 2023 (Nature Medicine, PMID 36849732) reported elevated plasma erythritol associated with major adverse cardiovascular events (MACE) in two cohorts (n=4,000+), with in-vitro and ex-vivo evidence of enhanced platelet aggregation. Replication is ongoing; FDA and EFSA have not changed their safety positions, but the signal is real and the additive is purely cosmetic. Better-established concern: GI tolerance — single doses above ~50 g cause osmotic diarrhea. Lower threshold for children.
AnnattoColorant
Natural yellow-orange colorant derived from the seeds of the achiote tree (Bixa orellana)
Natural FlavorsFlavor
Broad regulatory category of flavor constituents derived from natural sources. Composition is proprietary and not disclosed — 'Natural Flavors' can include several hundred different compounds depending on the target flavor profile, including hexane-extracted constituents and proprietary carrier solvents. 'Natural' is a regulatory definition (21 CFR §101.22), not a safety guarantee.

Fine silica powder used to prevent clumping
Citric AcidAcidulant
Natural acid derived from citrus fruits
Sodium CarbonatesBuffering Agent
Alkaline buffering agents used to adjust pH and improve stability of supplement formulations
