Example Input: This is the 2nd order i have placed for Bob's Red Mill Organic Flaxseed. It is a good quality whole flaxseed. We grind it a little at a time and sprinkle it on cereal and in yogurt. It keeps a long time in the freezer. I have been using this flaxseed for about a year now ,eating a tablespoon about every day and have noticed that my skin is softer , plus it keeps me regular, if ya know what i mean !!! Flaxseed is also a good way to get in some of the Omega 3's, that the body needs.
