Other Ingredients (3)
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 FlourFiller
Rice-based ingredients carry risk of inorganic arsenic contamination (FDA and Consumer Reports). Rice accumulates arsenic from soil at higher rates than other grains. Used as a cheap filler — adds nothing beneficial.
HypromelloseCapsule
Plant-derived capsule material from cellulose
