Other Ingredients (6)

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.

Magnesium StearateLubricant

A salt of stearic acid used as a lubricant in tablet and capsule production

Dicalcium PhosphateBinder

Calcium and phosphorus compound used as binder

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.

StarchBinder

Carbohydrate polymer used as a binder, filler, and disintegrant in tablets and capsules

Ascorbic AcidAntioxidant

Vitamin C used as an antioxidant preservative in supplements to prevent oxidation

How to Take It
