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.

Purified WaterSolvent
Water meeting USP specifications used as solvent/vehicle in gummies and liquids
Safflower Seed OilCarrier
Light, neutral oil from safflower seeds used as a carrier in softgels for fat-soluble nutrients
GlycerinHumectant
Sweet-tasting liquid used in soft capsules and liquids
