You know you are a health nut if…your high power blender hits 3000 uses! We were grinding flax seeds at the time. Dr Josh recommends 1-2 tablespoons of ground flax seed per day. BONUS TIP: Use a pepto-bismol 2 tablespoon (30cc) plastic cup and keep it inside your ground flax seeds in the fridge. Remember ground flax seeds only stay good for 2 months in the fridge.
