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.

InulinFiller

Prebiotic soluble fiber from chicory root, used as a filler and flow agent in capsules and tablets

Lactobacillus acidophilusProbiotic

Live probiotic bacterium native to the human GI tract and found in fermented foods. NCFM and La-14 are the most-studied strains with RCT evidence for digestive health, antibiotic-associated diarrhea, and lactose tolerance.
