SDG Lignans
Flax Seed Lignans are phytonutrients found in whole grains, nuts, seeds, fruits and vegetables.  Flaxseed has the highest levels of lignans known of all natural foods.  Flaxseed hulls have 20x more lignan than whole flaxseed.  Plant lignans are converted in the digestive tract into the mammalian lignans enterodiol and enterolactone.  It is these two mammalian lignans that have been linked to better reproductive organ health.  The mammalian lignans mimic estrogen and bind to estrogen receptors; this can block naturally occurring estrogen from antagonizing sensitive tissues and this is what is believed to be the reason that people with high amounts of lignan in their bodies have reduced rates of reproductive organ cancers.   Flaxseed hulls are high in fiber too. Lignans For Life offers a 90 ct bottle of pure flaxseed hulls (lignans) in vegi capsules.  Each capsule contains 630 mg flaxseed hulls and 33 mg of SDG lignans.
