High iron was not been confirmed by my analysis of stabilized ground flax. Iron was only 48 ppm as fed, 52 ppm as DM.

That was only one bag, so it doesn't mean much.

Iron content of linseed meal shown at Equi-Analytical is considerably higher, with a large range from 0 to 777.8 ppm as Dry Matter. The average is 286.5 ppm iron as DM. So if you feed 100 grams, you add..... only 28.65 mg of iron. That is a small fraction compared to the 980 mg of iron in 18 pounds of my hay.
