For Constipation "I had a bad reaction to Metamucil until I figured out what to do. I found that taking Metamucil dried up my stool and gave me constipation. I couldn't believe it didn't work because everyone loves it. BUT then I took magnesium with it and it was great. Magnesium diverts liquid to the colon so it gave me enough moisture to pass stool."

For Dietary Fiber Supplementation "Metamucil for sure causes some stomach cramping and constipation at first. You have to drink a lot of water with it and learn how much you can take. For example, I started with 2 tablespoons a day but learned one time a day was enough for me. Pass stools pretty great now. For sure, think there should be more directions on the box than just “take 1-2 scoops.”"

For Dietary Fiber Supplementation "All of a sudden, I would go 2 or 3 days and then have a large bowel movement over and over again. So, I tried powdered Metamucil. It worked a little. Then, I noticed I had green in my bowel movements. Metamucil is the only change in my diet for the past 2 weeks, and I haven't eaten anything green. It could be coincidence, and I all of a sudden have another medical issue, but I contribute it to the Metamucil and will stop taking it. It also seemed to make me slightly constipated. I mixed a teaspoon into my Ensure every day. I will have to go to a gastro doctor and run some tests. Green in stool? Really? Only I can have such luck."
