摘要

A time release composition is provided containing: a chromium complex having formula 3[Cr3O(carboxylate)6(ligand)3]+  (3)wherein carboxylate is a C2-C5 alkyl carboxylate and wherein ‘ligand’ is a ligand that (i) renders the chromium complex insoluble or only slightly soluble in water and (ii) is acid labile, being readily displaced under acidic conditions below pH=4 and replaced by water to make the resulting water soluble complex 2[Cr3O(carboxylate)6(H2O)3]+  (2),and the use of the time release composition for the time release delivery of complex 2.
