They used ground flaxseeds in this study (flax meal). You can buy flax meal but it goes bad quickly so the best way in my opinion is grind them in a coffee grinder and throw them in your oatmeal. Before grinding the seed's shell protects it and it will keep that way for a long time--once ground I think you only have roughly 48 hours (could be wrong on that--its something like that) before they go rancid--its cheaper and easier to just buy the seeds and grind them then to buy flaxseed meal
Will Brink:" The implication of the above study is obvious for women, but men reading this should see the clear potential benefits: flax seeds and high lignan flax oil may be a natural anti estrogen as powerful as Nolvadex and would explain why I have seen reductions in gyno in men taking high amounts of flax oil"
