Other Ingredients (12)

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.

Magnesium StearateLubricant

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

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 ConcentrateAnti-caking

A rice-derived blend used as a natural flow agent and anti-caking aid

Citric AcidAcidulant

Natural acid derived from citrus fruits

CrospovidoneDisintegrant

Cross-linked synthetic polymer used as a tablet disintegrant to help tablets break apart quickly in the stomach

Gum AcaciaBinder

Natural plant gum (acacia) used as a binder, stabilizer, and emulsifier in foods and supplements
