Fuente: WIPO "tomato" The present invention relates to compositions, in particular to lipid-based compositions that solubilise and/or encapsulate (sometimes high concentrations of) copper complex(es) (and/or derivatives or analogues thereof). Such lipid-based compositions offer a variety of uses, including in their capacity as topical or ingestible formulations. Such compositions permit delivery of high concentrations of copper complex(es) (and derivatives) in a highly bioavailable form.
