Other Ingredients (3)

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.

Rice ExtractFiller

Rice-based ingredients carry risk of inorganic arsenic contamination. Vague labeling — 'rice extract' does not specify what is extracted or standardized. Used as a cheap filler with no supplemental benefit.

HypromelloseCapsule

Plant-derived capsule material from cellulose
