Ground Flaxseeds are easily and quicker absorbed in the body, so always chose ground Flaxseeds. The seeds have a hard shell and are small so they usually goes straight through the body if not grounded.
Another great effect of just a small dose as one or two tablespoons per day of Flaxseeds will help you burn fat. I make raw crackers out of Flaxseeds and they gives me a sense of fullness and keep me energized. I also use Flaxseeds to make raw pizza crusts and much more. They are also cheap, so no excuse not to buy a big bag today.
