For Irritable Bowel Syndrome "I started having emergency runs to the bathroom before my first class every day in college. Needing to hold it when stuck in traffic was the worst! I started having cramping all over my abdomen, and with internet diagnosing myself, I swore I had some serious disease or cancer. I went to the doctor, and he did some tests, and I was fine, and he recommended Metamucil. It took my body a while to get used to the new fiber. Symptoms would come and go, and after about a week or two, I started realizing how much I was actually able to forget about even having stomach problems! I still have some cramping, and the product does seem to cause some bloating. However, I went from only having a couple good days a week to only a couple bad days a week."

For Irritable Bowel Syndrome "I had the worst diarrhea for over two years and complete bowel incontinence for twenty-five years. I was prescribed cholestyramine but could not get myself to take this plastic resin powder. I did some research and saw a small similarity with Metamucil, so I tried it. That was more than a month ago. It changed my life, no more cramps, bloating, gas, diarrhea, no more complete poop accidents in public. I wake up, move my bowel perfectly normal, and I am good to go all day. I am beyond grateful. I take 2 teaspoons of powder a day every day. Please give it a try."

For Constipation "Metamucil is great, but the new formula with Stevia does not work the same. It's not even close. I won't get detailed, but it simply does not do its job. I feel more bloated after taking it. Do not buy it with Stevia."

For Irritable Bowel Syndrome "Been having bowel problems for the past three months. Doctors prescribed me a lot of different medications, medicines, etc., however, it just made my stomach a whole lot worse. I kid you guys not, Metamucil worked for me instantly. My bloating went right down, my stomach feels a whole lot lighter, I am able to go to the toilet normally, I don't feel so sluggish and tired, I've also got more energy throughout the day. I 100% recommend this to anyone suffering from IBS or bowel problems, it's amazing!"

For Irritable Bowel Syndrome "Regular use changed my life. I have no stomach pain anymore. I hurt nearly every day before this. Now my life is so much better. I did not have constipation. I suffered pain nearly every morning. Now my stomach empties every morning, and I have virtually no pain. The first few days, I felt full and bloated after drinking Metamucil. Now I am adjusted to the fiber and feel so much better."

For Constipation "My first experience mixing it with water was disgusting. I felt bloated, belching, and thought I was going to throw up. On the second day, I mixed it with 2 teaspoons of plain yogurt and ate it with a spoon with a 300-milliliter water chaser. Perfecto! Works well on gut poo management. Good to go."

For Constipation "After months of constipation, 1 on the Bristol scale, my doc gave me Metamucil, unflavored. I take one tablespoon with water. At first, it tasted terrible like cardboard, and I had gas, bloating. However, within 1 day I had normal BM, 4 on the Bristol scale. And I feel 10 times better, my energy is back, and moods are much better. Over time the gas and bloating are gone, and I've gotten used to the taste, now it tastes like chocolate milk. Definitely the best laxative I've ever used."

"All my life I have had gas, indigestion, constipation, then diarrhea. Also, the pain in my stomach would be unbearable. I took all over-the-counter and doctor medication, had stomach scans, everything the doctor would suggest, but with no regular relief. My new doctor recommended Metamucil, I've never felt better. I have at least two BMs a day. All constant big, fluffy stools. No gas, no bloating, no nausea, it's all regular, and I feel wonderful. Wish I had tried this years ago. I feel great. I stir it in cold water and quickly drink it so it doesn't get thick, the taste is great, and it's sugar-free. Thank you, Metamucil."
