Here are some general guidelines to follow in selecting a good flaxseed oil product: *Make sure the oil is derived from 100 percent third-party certified organic flaxseed. Oil expressed from non-organic seed may contain pesticides and herbicides. *Do not take the oil in capsule from. Your only assurance of quality is taste. Buy the oil in liquid form in opaque bottles. *Make sure the oil is as fresh as possible and not past it's expiration date. *Make sure it is clearly indicated that the oil is expeller-pressed. *To gain more benefit, use flaxseed oil high in lignans.
