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.
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.
Microcrystalline CelluloseBinder
Plant-derived cellulose used as a binder and filler in supplements
Sodium Stearyl FumarateLubricant
A standard tablet/capsule lubricant, often used in place of magnesium stearate.
