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.

Magnesium StearateLubricant

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

Natural Color (unspecified)Colorant

Umbrella declaration for a colorant from a natural source (fruit, vegetable, or plant extract) that the label does not name specifically

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

Microcrystalline CelluloseBinder

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