Pharmacology Action:  Secoisolariciresinol diglycoside, is a plant lignan most notably found in flaxseed (linseed). SDG has estrogenic and antioxidant activities. It may also have antiestrogenic, anticarcinogenic, antiatherogenic and antidiabetic activities.SDG has estrogenic and antioxidant activities.

Lignans are one of the two major classes of phytoestrogens; the other class is the isoflavones. Plant lignans are polyphenolic substances derived from phenylalanine via dimerization of substituted cinnamic alcohols. Mammalian lignans are lignans derived from plant lignans. For example, following ingestion, SDG is converted to the aglycone secoisolariciresinol, which is then metabolized to the mammalian lignans enterolactone and enterodiol. Most of the effects of oral SDG are mediated by enterolactone and enterodiol.
