I had constipation, tried to include fiber in diet from fruits and veggies but guess what, it was difficult that way. Then I came to about ground flax seed, decided to give it a try, took three teaspoon of it every night for three nights, did not help, increased the dose to three table spoon, from fourth day I have been going regularly without any effort. Drink a lot of water though. It builds immune system, because of that or adding honey to it, which I tried to drink everyday but could never make it a routine, my allergy is gone. Oh one more thing, my cholesterol is down to normal, for which I have been having medicine for a long time. Fiber in your diet actually helps reduce cholesterol. Take it, you will thank me and flax seed.
