Other Ingredients (9)
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.
Silicon DioxideAnti-caking
Fine silica powder used to prevent clumping
Beet ColorColorant
Natural red-pink colorant from dehydrated beets or beet juice; the pigment is betanin
DextroseSweetener
A simple glucose sugar used as a bulking agent, sweetener, and tablet diluent
