Other Ingredients (5)
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.
SucroseSweetener
Added sugars and high glycemic load; dental caries risk
StarchBinder
Carbohydrate polymer used as a binder, filler, and disintegrant in tablets and capsules
Gum AcaciaBinder
Natural plant gum (acacia) used as a binder, stabilizer, and emulsifier in foods and supplements
Capsule ShellCapsule
Generic capsule shell where the label does not specify the material. Common materials are hypromellose (HPMC) for vegetarian capsules and gelatin for traditional capsules — both are GRAS-listed and safe. Fish gelatin and pullulan variants also exist.
