CarrageenanThickener

Can break down into poligeenan (a known inflammatory) under stomach acid conditions. Tobacman (2001, Environmental Health Perspectives) reviewed evidence linking carrageenan to intestinal inflammation and ulceration. Major food brands (Silk, Stonyfield) have voluntarily removed it. Used only as a thickener — provides no health benefit.

Magnesium StearateLubricant

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

PotassiumMineral

Essential mineral naturally present in many plant-based supplement ingredients

PullulanCapsule

Polysaccharide produced by fungal fermentation, used as a vegan capsule material
