Actually yes, I should have clarified that although flax seed oil is an excellent add to anyones regime, it is actual flax seed that has benefits for fibre in ones diet/regime...I suggest you take both flax seed, oil and fish oils (omegas 3-6-9).
Flax Seed is High in Fiber: You’d be hard-pressed to find a food higher in fiber -- both soluble and insoluble -- than flax. This fiber is probably mainly responsible for the cholesterol-lowering effects of flax. Fiber in the diet also helps stabilize blood sugar, and, of course, promotes proper functioning of the intestines.
My bum is broken....there's a big crack down the middle of it! LOL :)
