A convenient all-in-one Essential Fatty Acid (EFA) and high-fiber supplement... Combines certified-organic unrefined flax seed oil and lignans from flax seed fiber. Lignans are a very important component of high-fiber foods originating from plants. Flax seeds are the richest available source of plant lignans. Lignans are structurally similar to estrogens and work within the body to balance estrogen levels. Omega Nutrition's concentrated lignan products including Nutri-Flax®, Hi-Lignan® Nutri-Flax® Capsules, and Hi-Lignan® Flax Seed Oil, normally have up to 30% more lignans than whole or ground flax seeds.
