Advancements in curcuminoid formulations: An update on bioavailability enhancement strategies curcuminoid bioavailability and formulations.

Here, we provide a current review of strategies aimed at improving the bioavailability of curcuminoids, a group of compounds with therapeutic potential. This review discusses formulations from the traditional supplementation approaches to the innovative methods to enhance solubility and bioavailability, including cyclodextrins and hydrophilic carriers. Additionally, colloidal delivery strategies, such as micelles, liposomes, solid lipid particles, and emulsions, are examined as promising vehicles for curcuminoid delivery. The review underscores the importance of clinical trials in assessing the efficacy of these formulations and highlights a pivotal yet frequently neglected factor in curcuminoid research: the differentiation between total and free curcuminoid quantification. In summary, this concise review evaluates existing curcuminoid formulations and explores innovative approaches to improve their bioavailability.
