Other Ingredients (10)

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.

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.

Beet ColorColorant

Natural red-pink colorant from dehydrated beets or beet juice; the pigment is betanin

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

Citric AcidAcidulant

Natural acid derived from citrus fruits

Hydroxypropyl CelluloseBinder

An inert modified-cellulose polymer used as a binder, film-former, and disintegrant.

Microcrystalline CelluloseBinder

Plant-derived cellulose used as a binder and filler in supplements
