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
Lithothamnion CalcareaFiller
Calcified red seaweed used as a whole-food tablet base and natural calcium/magnesium source (common in food-based multivitamin lines)
Beet ColorColorant

How to Take It
Take it anytime
No evidence a formula this broad works better at any particular hour. Take it with a meal containing fat — the vitamins A, D, E and K in it absorb poorly without one.
