Promotive Effects of the Dietary Organic Germanium Poly ...

Poly-trans-[(2-carboxyethyl) germasesquioxane] (Ge-132) is the most common organic germanium compound.This compound has many physiological effects, which are mediated via the modulation of immune-system activation. The intake of dietary Ge-132 causes fecal color changes in humans, and we studied the mechanism of this in a rodent model.

Evaluation of the Effects of Dietary Organic Germanium,

Poly-trans-[(2-carboxyethyl) germasesquioxane] (Ge-132) is the most common organic germanium compound.The ingestion of Ge-132 promotes bile secretion. We assessed the rat caecal characteristics after the administration of Ge-132 and raffinose, a prebiotic oligosaccharide, because both Ge-132 and some prebiotics can change the fecal color to yellow.
