Flax Lignans and Heart Health
Iowa State Study on Flax Lignans and Heart Health

Purpose: To demonstrate the efficacy of Beneflax™ flaxseed lignan (SDG) concentrate to lower serum cholesterol levels.

Background: Flaxseed has been studied for various health benefits in humans, including prostate health, glucose control, and cardiovascular health. Cholesterol levels and high blood pressure are known to be risk factors for cardiovascular disease. Whole flaxseed has had variable effects on serum lipid levels, perhaps a consequence of variations in the amounts of secoisolariciresinol diglucoside (SDG) found in different flax cultivars, making the study of this bioactive compound difficult.

Hypothesis: Flaxseed lignan (SDG) extract (Beneflax) significantly lowers total and LDL cholesterol. Flaxseed lignans also lower blood pressure and fasting glucose levels.
