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.

SorbitolSweetener

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

Cold-pressed olive oil used as a carrier and filler in softgel capsules for fat-soluble nutrients
