Efficacy of flaxseed: Flaxseed is the species with the highest linolenic acid content in nature, which has the functions of lowering blood pressure, lowering blood lipid, preventing coronary heart disease and cardiovascular diseases. Flaxseed also contains more lignans, which can effectively prevent the growth of diabetes and tumors. EPA and DHA in flaxseed also contribute to the formation, growth and development of brain cells, and play an important role in improving teenagers' intelligence and protecting their eyesight. I suggest you buy from Inner Mongolia, and recommend Mengguxiang.
