Other Ingredients (9)

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.

SorbitolSweetener

A FODMAP sugar alcohol that may trigger GI discomfort (bloating, gas) in individuals with IBS or sorbitol malabsorption, even at small amounts found in supplements. Avoided in low-FODMAP diets.

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

Silicon DioxideAnti-caking

Fine silica powder used to prevent clumping

Fruit Juice (unspecified)Colorant

Juice or juice concentrate used primarily for natural color and flavor in gummies
