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.
Artificial FlavorsFlavor
Composition is proprietary and not disclosed on the label, so allergens or solvents cannot be verified. Naturally flavored alternatives are more transparent.
MannitolSweetener
A FODMAP sugar alcohol that can cause GI distress (bloating, gas, diarrhea) at higher doses. Supplement amounts are typically small, but individuals with IBS or sugar alcohol sensitivity may react even at low doses.
Beta-Carotene (color)Color
Beta-carotene used in small amounts as a colorant/antioxidant.
Tapioca DextrinCarrier
A starch hydrolysate from tapioca used as a carrier and flow agent
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.
Silicon DioxideAnti-caking
Fine silica powder used to prevent clumping
Beetroot Juice PowderColorant
Natural red colorant and mild flavoring derived from beetroot; often spray-dried onto maltodextrin carrier
