Other Ingredients (12)

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.

Natural Cherry FlavorFlavor

A flavoring derived from natural cherry sources

Natural FlavorsFlavor

Broad regulatory category of flavor constituents derived from natural sources. Composition is proprietary and not disclosed — 'Natural Flavors' can include several hundred different compounds depending on the target flavor profile, including hexane-extracted constituents and proprietary carrier solvents. 'Natural' is a regulatory definition (21 CFR §101.22), not a safety guarantee.

Silicon DioxideAnti-caking

Fine silica powder used to prevent clumping

Beetroot Juice PowderColorant

Natural red colorant and mild flavoring derived from beetroot; often spray-dried onto maltodextrin carrier

Citric AcidAcidulant

Natural acid derived from citrus fruits
