Other Ingredients (4)
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 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.
Magnesium StearateLubricant
A salt of stearic acid used as a lubricant in tablet and capsule production
GelatinCapsule
Protein derived from collagen, used in traditional capsule shells
