Disclosed are nutritional compositions and methods for preparing the compositions, comprising fat, protein, and carbohydrate, including a combination of curcumin, demethoxycurcumin, and bisdemethoxycurcumin, which combination is solubilized in a polar oil having an HLB value of from about 0.7 to about 14 wherein the weight ratio of the bisdemethoxycurcumin to the curcumin is from about 1:1 to about 1:7 and the weight ratio of the bisdemethoxycurcumin to the demethoxycurcumin is from about 1:1 to about 1:2.5. The composition provides a selected ratio of curcuminoids having improved biological activity, bioavailability, and reduced color impact.
