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.

AstaxanthinFood

A reddish carotenoid antioxidant, typically sourced from Haematococcus pluvialis microalgae.

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.

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