Abstract: Formulations comprising complexes of peptides with hydrophobic bioactive molecules are described herein. The invention more specifically relates to collagen peptide and curcuminoid complexes and compositions comprising the complexes. The compositions and formulations comprising the protein hydrolysate peptide-hydrophobic bioactive molecule complexes are water-soluble, stable at physiological and acidic pH, synergistically enhance the systemic bioavailability of the biomolecules and peptides, and are capable of delivering a high therapeutically effective amount of the bioactive molecules via oral route. The compositions and formulations comprising the collagen peptide-curcuminoid complexes provide significantly high levels of bioavailable curcuminoids that are water soluble and stable at physiological and acidic pH along with significant anti-inflammatory effects offered by collagen peptides.
