Flaxseed is a good source of many nutrients, including protein, fiber, omega-3, omega-6, omega-9 fatty acids, thiamine, and copper. Omega-3 fatty acids contribue to the normal function of the heart. DHA plays important roles in the functioning of the brain and the eye. A BALANCED OMEGA SUPPLEMENT: Omega 3 (ALA) and omega-6 (LA) are essential nutrients the body needs but can’t produce on its own. Omega-9 helps ensure a balanced intake of all 3 fatty acids.
