Cinnamaldehyde is 52% absorbed through the skin and shown to be rapidly absorbed from the gut [A34266].
Cinnamaldehyde is metabolized and excreted primarily in the urine and, to a minor extent, in the feces [A34266]. After oral or intraperitoneal administration to rats and mice, 69–98% of the dose of cinnamaldehyde was recovered in the urine and feces within 24 h [A34266].
