Flax Lignan Gold is 20% flax particulate, containing 11 mg of lignans per serving. Current research indicates that lignans have important nutritive and preventive properties. Lignans are phytonutrients plant compounds found in high-fiber foods such as grains, legumes, fruits, and vegetables. Flaxseeds are the most abundant source of plant lignans, containing over 100 times more than other common plant sources.

Several clinical research centers, including the National Cancer Institute, are currently studying the preventive and nutritional benefits of flaxseed lignans on humans.
