Other Ingredients (6)
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.
XylitolSweetener
A FODMAP sugar alcohol that can cause GI distress (bloating, gas, diarrhea) at moderate doses (>10-20g/day), though supplement amounts are typically small. Extremely toxic to dogs — households with pets should store securely.
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.
Rice HullsAnti-caking
Ground outer husk of rice grains used as a plant-based flow and anti-caking agent
Citric AcidAcidulant
Natural acid derived from citrus fruits
