Changes in mean serum metabolite concentrations in overweight male adult cats (n = 14) resulting from the consumption of dietary choline at 6 x NRC RA (378 mg/kg BW0.67) or 8 x NRC RA (504 mg/kg BW0.67) for 3-week periods.

Green and orange arrows represent increased serum metabolite concentrations with 6 x NRC RA or 8 x NRC RA, respectively. A red “X” represents a hypothesized decreased activity of said pathway.
