Animal studies have shown SDG can prevent the development of atherosclerosis and diabetes, and has beneficial modifying effect on blood and cholesterol levels.

Secoisolariciresinol diglucoside can be isolated from de-fatted (hexane extraction) flaxseed by extraction of the lignan polymer precursor with a water/acetone mixture, followed by acetone removal and alkaline hydrolysis.1
