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.

Natural Cherry FlavorFlavor

A flavoring derived from natural cherry sources

Magnesium StearateLubricant

A salt of stearic acid used as a lubricant in tablet and capsule production

Silicon DioxideAnti-caking

Fine silica powder used to prevent clumping

StarchBinder

Carbohydrate polymer used as a binder, filler, and disintegrant in tablets and capsules

CrospovidoneDisintegrant

Cross-linked synthetic polymer used as a tablet disintegrant to help tablets break apart quickly in the stomach
