Safety assessment of a solid lipid curcumin particle preparation: In vitro and in vivo genotoxicity studies.

Curcumin, one of the three principal curcuminoids found within turmeric rhizomes, has long been associated with numerous physiologically beneficial effects; however, its efficacy is limited by its inherently low bioavailability. Several novel formulations of curcumin extracts have been prepared in recent years to increase the systemic availability of curcumin; Longvida®, a solid lipid curcumin particle preparation, is one such formulation that has shown enhanced bioavailability compared with standard curcuminoid extracts. As part of a safety assessment of Longvida® for use as a food ingredient, a bacterial reverse mutation test (OECD TG 471) and mammalian cell erythrocyte micronucleus test (OECD TG 474) were conducted to assess its genotoxic potential.

Safety assessment of a solid lipid curcumin particle preparation: acute and subchronic toxicity studies.

Curcumin, a polyphenol, is obtained from turmeric, the ground rhizomes of Curcuma longa L. Extensive research over the past half century has revealed several health benefits of curcumin. The objective of the present study was to investigate potential adverse effects, if any, of a novel solid lipid curcumin particle (SLCP) preparation in rats following acute and subchronic administration.
