Lignans are high in antioxidants, high in fiber and have anti-estrogenic effects. There are 9 main potential health benefits from Flaxseed lignans. See below or go directly to the

Lignans are phytonutrients that may help regulate hormone levels.
Lignans are high in antioxidants and may support the immune system.
Lignans compete with estrogen which may help with menopausal symptoms. 
Lignans inhibit certain enzymes needed in the conversion of testosterone to DHT.  The result is lower DHT which may improve prostate health.
Lignans inhibit HSD enzyme which may reduce the stress hormone Cortisol.

Breast Health

Studies have shown that women with high levels of lignans in their bodies, as measured from urine and/or blood samples, have a reduced rate of breast cancer. Read more about lignans reducing the risk of breast cancer.

Lignans Reduce LDL (Bad) Cholesterol Levels

A study by the University of California at Davis concluded that "High-lignan Flax has the unique property of decreasing Ox-LDL" Read the full report found on the US government National Institute of Health web site at this location.

High Antioxidant Value

Lignans have a higher antioxidant (ORAC) Value than any other fruit or vegetable. See Orac Chart.

Cardiovascular Disease

Diets rich in foods containing plant lignans (whole grains, nuts and seeds, legumes, fruits, and vegetables) have been consistently associated with reductions in risk of cardiovascular disease. However, it is likely that numerous nutrients and phytochemicals found in these foods contribute to their cardioprotective effects. In a prospective cohort study of 1,889 Finnish men followed for an average of 12 years, those with the highest serum enterolactone levels (a marker of plant lignan intake) were significantly less likely to die from coronary heart disease (CHD) or cardiovascular disease than those with the lowest levels (11).

Ovarian and Uterine Health

Lignans have anti-estrogenic properties that mimic estrogen and bind to estrogen receptors but dont have the same antagonistic effects of estrogen. Plant estrogens are a cleaner form of "estrogen" and when more plant lignans are consumed, more of your normally occurring (endogenous) estrogen is flushed out of the body. It is believed that this is the mechansim behind the studies that indicate reduced rates of ovarian cancer and reduced rates of uterine cancer. Nothing is guaranteed to prevent these cancers but healthy diets incuding fresh fruits and vegetables high in lignan content may reduce the risk.

Prostate Health

A case-controlled study conducted in Scotland found that higher serum enterolactone concentrations were associated with a lower risk of prostate cancer. Enterolactone is produced in the intestines by bacteria acting on lignans.

Flaxseed SDG may have a therapeutic role in lupus nephritis. (Clark W. et al Lupus,: 429, 2000) Vegetarian men have a lower incidence of prostate cancer than omnivorous males. Plant lignans give rise to the mammalian lignans, enterodiol and enterolactone; the richest source is linseed (flaxseed). More about Prostate Cancer Prevention.

Colon Health

Flaxseed, the richest source of mammalian lignan precursors, such as secoisolariciresinol diglycoside (SDG), has been shown over the short term to decrease some early markers of colon cancer risk. Read more about this study and other studies on reducing the risk of colon cancer here.

Hot Flashes and Menopause

A Mayo clinic study shows that, "lignans provide a more natural estrogen treatment for menopause and hot flashes than synthetic hormone therapy and therefore are a potentially healthier treatment for both." Sandhya Pruthi, MD. Mayo Clinic in Rochester, MN. Published February 1, 2008 Read more about menopause relief.

Hair Growth

There are studies that indicate that people with high amounts of lignans in their bodies have a reduced rate of hair loss and other studies that have shown hair regeneration. Hair loss can be caused by the hormone DHT. Flaxseed lignan can inhibit the production of the enzyme that converts testosterone into DHT. One asian study on men over a 6 month period showed significant improvement in hair growth in an average of 2 months.

Canine Cushings Treatment.

Dr Jack Oliver DVM PhD issued a report in 2009 indicating that flaxseed lignans may be a good treatment for Canine Cushings disease. We did a survey of our customers in 2012 and 85% of those that responded said they saw improvements in an average of 2 months. Another study showed a reduction in tumor sizes.

Reactive oxygen species (ROS) have been implicated in the development of diabetes mellitus. SDG isolated from flaxseed is an antioxidant. An investigation was made of the effects of SDG on the development of diabetes in rats, to determine if SDG can prevent/reduce the development of diabetes and if this prevention/reduction is associated with reduction in oxidative stress. RESULTS: SDG prevented the development of diabetes by 75%.(Prasad K, et a, Mol Cell Biochem, 206(1-2): 2000; Prasad K. Mol Cell Biochem, 209(1-2): 89.2000)
