May trigger hyperactivity in sensitive children; potential link to allergic reactions
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.
Acesulfame PotassiumSweetener
Older NTP rodent studies (1980s, contested) reported lymphoma and leukemia at very high chronic doses; modern reviews (FDA 2003, EFSA 2000) concluded no cancer risk at human exposure levels but the issue is not fully resolved (Mishra 2020 review). Animal evidence suggests gut microbiome disruption (Bian 2017 — male mice on Ace-K showed altered microbiota and metabolic markers). Manufacturing uses methylene chloride, with potential residue concerns. Purely cosmetic additive — risk:benefit unfavorable for supplements.
Natural and Artificial FlavorsFlavor
The 'artificial' component means synthetic chemicals are used, but the exact compounds are proprietary and not disclosed on the label. If you have sensitivities or allergies, you cannot verify what's in it. Products using only natural flavors are more transparent.
Soy LecithinEmulsifier
Widely used emulsifier derived from soybeans
StarchBinder
Carbohydrate polymer used as a binder, filler, and disintegrant in tablets and capsules
Gum BlendThickener
Generic term for a mixture of food-grade gums such as guar, xanthan, and acacia
PotassiumMineral
Essential mineral naturally present in many plant-based supplement ingredients
How to Take It

Total daily protein is what matters — the post-workout "anabolic window" has not held up in controlled trials.
