Cinnamaldehyde microcapsules enhance bioavailability and regulate intestinal flora in mice.

The effects of cinnamaldehyde microcapsules on the concentration of cinnamaldehyde and its metabolites in plasma, urine, and feces, the antioxidant capacity, and the intestinal flora in male C57/BL6 mice were evaluated by oral administration for 7 weeks. Microencapsulation significantly increased the contents of cinnamaldehyde, cinnamyl alcohol, and methyl cinnamate in plasma and decreased those in urine and feces excretion ( < 0.05).
