Other Ingredients (12)

Artificial ColorsColorant

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.

FructoseSweetener

Added free fructose is metabolized in the liver and at habitual intake is linked to elevated triglycerides, hepatic fat accumulation, and insulin resistance; an avoidable sugar load with no supplement benefit.

MaltodextrinBinder

Spikes blood sugar faster than table sugar (glycemic index 85–105). Research links it to gut bacteria changes that may promote intestinal inflammation (Nickerson et al. 2015). Used as a cheap filler — adds nothing beneficial.

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 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.

SucroseSweetener

Added sugars and high glycemic load; dental caries risk

Magnesium StearateLubricant

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