The present invention is directed to metal supplementation of beverages. More particularly, it is directed to a metal containing complex coacervate core micelle comprising a negatively charged chelating agent, a low molecular weight natural food-grade polymeric cation, and water. It is also directed to a process to produce said metal containing complex coacervate core micelle, and to the use of said metal containing complex coacervate core micelle to supplement beverages with a source of highly bioavailable metal. It is also related to a beverage comprising said metal containing complex coacervate core micelle.
