Other Ingredients (6)

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.

Rice HullsAnti-caking

Ground outer husk of rice grains used as a plant-based flow and anti-caking agent

Gum AcaciaBinder

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

PullulanCapsule

Polysaccharide produced by fungal fermentation, used as a vegan capsule material

Sunflower Seed OilCarrier

Common vegetable oil from sunflower seeds used as a carrier in softgels for fat-soluble nutrients
