What is Metamucil?

Metamucil is a dietary supplement made with psyllium husk that claims to provide a “high-quality fiber intake with each portion”.

Its primary purpose is to improve the digestive function of consumers and offer a healthy way to lose weight and suppress their appetite.

Metamucil has been marketed as a product for metabolism issues.

  • International Journal of Pharmaceutics – Additional benefits of psyllium include helping with diarrhea and constipation.
  • Appetite – Then we have the possible effect of psyllium as an appetite suppressor, which has been studied many times before. According to this journal, “psyllium reduces hunger feelings and energy intake.”
  • Critical Reviews in Food Science and Nutrition – Maltodextrin is a carbohydrate making psyllium husk easy to digest. According to the journal, maltodextrin is “preferred to that of common sugars and their use as fat replacers leads to a reduction in the energy density (kJ/g) of food products.”

When Did Metamucil Start?

Psyllium husk has been used as an excellent fiber source for centuries. However, it wasn’t until 1934 when the product began getting marketed by Metamucil, which is now the official name for the psyllium husk and powder.

Today, there are various ways to take Metamucil, as it is offered in Metamucil powder, Metamucil wafers, and even Metamucil capsules.

There are also different versions of Metamucil, including:

  • Premium Blend Sugar-Free Powder
  • Fiber Gummies
  • Psyllium Fiber Capsules
  • Fiber Thins
  • Sugar-Free Smooth Powder
  • Real Sugar Coarse Powder
  • 14-Day Citrus Cleanse

Metamucil is a product of Procter & Gamble, a multinational consumer goods company based in Cincinnati, Ohio. Procter & Gamble products include Ariel, Tide, Bounce, Downy, Pampers, Bounty, Charmin, Always, Gillette, Venus, Head & Shoulders, Vicks, Olay, Crest, and Oral-B.

Procter & Gamble is not BBB accredited, but it still got an “A+” BBB rating and they earned 1.18 out of 5 stars based on an average of 28 customer reviews. Currently, they have 252 complaints closed in the last 3 years and 79 complaints closed in the last 12 months.


Metamucil Claims

metamucil claims

As a product mainly designed to improve overall metabolism, help with weight loss, and digestive benefits that only a few other products offer, Metamucil is the most popular of its kind.

Using psyllium husk, this product claims to provide the perfect way to maintain healthy body composition by reducing the fat intake and improving digestive processes, working simply as a laxative.
Metamucil also works to:

  • Decrease weight
  • Burn fat
  • Avoid constipation
  • Aid with other digestive problems such as diarrhea and vomiting

All of this is a result of the amount of fiber Metamucil offers.


Metamucil Ingredients

metamucil ingredients

As we’ve said before, Metamucil is mainly psyllium husk. This ingredient is practically 90% of the whole formula. However, there are other important Metamucil ingredients, such as:

  • Maltodextrin
  • Aspartame
  • Sodium
  • Calcium
  • Potassium
  • Phenylalanine

These ingredients are considered inactive, so they don’t offer much of an effect.

Aspartame, a sweetener, works within Metamucil to help taste the product, as it is one of the most potent sweeteners.

According to the journal Food and Chemical Toxicology, aspartame has been used “safely in food for more than 30 years.”

The real work of Metamucil is thanks to psyllium, of course. It has been linked to many benefits, such as:

  • Bodyweight reduction
  • Satiety

Metamucil Benefits

metamucil Benefits

Due to its highly beneficial ingredients, Metamucil is responsible for:

  • Increased fiber intake
  • Helps to lose fat
  • Aids at weight loss
  • Suppresses appetite
  • Improves metabolism
  • Avoids constipation
  • Improves the digestive system

According to the journal Alimentary Pharmacology & Therapeutics, “Mixed fibre and psyllium were equally efficacious in improving constipation…and relieving flatulence and bloating.” Plus, the British Journal of Nutrition found that psyllium husk could help reduce blood pressure.

Dietary fiber in general can be beneficial as well. According to the International Journal of Molecular Sciencesdietary fiber may play a beneficial role in inflammation of the bowels, while research in Nutrition Today found that these kind of fiber supplements can help gastrointestinal health.

Finally, fiber can drive metabolic health benefits as well, per the Journal of the American Association of Nurse Practitioners

Side Effects

Metamucil Side Effects

As a product that is used globally, Metamucil isn’t known to produce many side effects.

However, some Metamucil reviews have mentioned mild to moderate effects from using the product. These effects include:

  • Flatulence
  • Stomach Pain
  • Nausea
  • Vomiting
  • Cramping
  • Constipation
  • Allergic Reactions

Because of this, it is essential to talk to a doctor before taking Metamucil, especially if you suffer from any medical conditions.

Does Metamucil Work?

Despite a clear positive amount of Metamucil directions, there’s still a lot to say about its effectiveness and overall benefits.

As you know, Metamucil in all forms is claimed to offer many positive results. However, these benefits are not that clear most of the time, according to many consumer reviews.

So, yes, the product will most likely display results, but the effects are not magical. The product will improve a user’s diet and increase fiber consumption, which comes with many benefits.

Metamucil and Weight Loss

metamucil weight loss

Metamucil capsules and powder have been studied as a possible weight-loss supplement for decades.

It has been accepted as an effective treatment for obesity conditions, thanks to its effect on body composition, weight, and overall fat depositories in the body.

The Metamucil weight loss effects are due to how psyllium works in the digestive system, relieving any obstruction and provoking an instant release of liquids that cleanse the bowels and digest everything a lot easier.

Psyllium husk is known as an influential factor in the loss of body mass, especially when taken 30 minutes before each meal, which helps to improve the overall digestive system to absorb what matters and dismiss what’s not.

According to the journal PLoS One, “Dietary supplementation with 6 g/day of psyllium over 6 weeks improves fat distribution and lipid profile.”

Reddit Reviews

Metamucil Reddit Reviews

Many consumers trust Reddit for information about supplements, pre-workouts, and meal replacements. With more than 130,000 active communities, there’s something for everyone on the platform. We decided to research Metamucil Reddit reviews to see what we could learn.

The reviews suggest that while it has been well received, some users didn’t like the product. In this case, users brought up concerns about whether the pill was as effective as the powdered drink mix at easing digestive issues.

What Users Are Saying

What Users Are Saying

“Metamucil tastes great and is easy to swallow. And it works. It is a good source of fiber and it stops the sweet cravings.”

“Causes pain, nausea, bloating cramps, constipation, and trouble breathing.”

“I’ve taken fiber pills in the past but none have worked as good as this. My concern is that I get severe heartburn 15 minutes after I drink this. Fiber is supposed to suppress acid so I don’t know why this is happening to me.”

Bottom Line

The Bottom Line on Metamucil

Well now, are we raving over this fiber supplement? Well, we like Metamucil’s longevity as a product and we found positive comments, but we are hesitant to suggest you pick up a bottle or canister. The science is there, clinical research shows it can help decrease hunger and improve regularity, but this brand is no better than a generic version at your local superstore. Plus, it’s always a good idea to increase your fiber intake with foods rather than supplements.

If you’d like to shed more pounds of fat, we suggest you go with a program that contains clinically-tested ingredients and offers plenty of bang for your buck.

Among the best products we’ve seen this year is one called Noom. An extensive food database, personalized meal plans, human coaching, food and exercise tracking and more come with the weight-loss app.

Also, the makers of Noom are so confident in their product they’re offering a free trial offer, which is a good sign.

  • Must add a sweetner.
    Rose (Verified Purchase)

    I wanted psyllium fiber that was smooth but was disappointed that Metamulcil doesn’t make one without artificial sweeteners-if they Must add a sweetener, why not stevia? It is a natural leaf that’s been used safely for decades.

    • Paul

      They make it with real sugar. You just gotta look for it

    • Maribel (Editor)

      Hi Rose, Metamucil offers Sugar Free Orange Smooth Powder.

  • It does not contain sugar.
    kobio (Verified Purchase)

    That’s only in the sugar free formula. Just don’t use the sugar free Metamucil if you are concerned about Aspertame.
    Regular metamucil does not contain this artificial sweetener.

  • Concern with urine smell

    Can Metamucil make your urine smell strong?

    • Bev

      I notice a big change in the odor of my urine when I take Metamucil or any brand of psyllium husk. I don’t know why so few people remark about this. The next time I go to the doctor, I’ll ask about it.

      • Robin

        I was specifically researching Metamucil for this exact reason. Ive been taking it for 2 weeks now and I have noticed a stronger odor to my urine.

        • Don

          Love the Metamucil and have great results. I too have noticed a strong different odor in my urine and stool. What is the answer to this odor change?


        • Your Name

          i would say if you have strong smell to your urine, you may have and std

    • Your Name

      Bev and Robin,

      I have witnessed the same issue with strong smelling urine.At my recent physical this week I ask my Doctor and he seemed to think it was the Metamucil and not another health issue. What is the manufactor’s answer?


      • Brian

        Could be your body detoxing with all the good soluble fibre. Could also be the aspartame. Try drinking a litre of diet coke and see if it smells the same. I’ve been using Metamucil to good effect but the aspartame worries me a little. There is a Metamucil Natural or something with some sugar and a little aspartame lol but prob less aspartame. However that one is “granular” I think it’s called and some people find it hard to drink as in gag reflex. Saw a bag of psyllium for $7.50 in the supermarket today so maybe I’ll try making up my own mix. Recommend Metamucil wholeheartedly to anyone though. Give it a try.

    • Maribel (Editor)

      Hi Donna. Metamucil is know for removing waste from them body, expelling them as urine. So, there is a possibility that urine may smell different.

  • Improved my bowel movements
    DDabney (Verified Purchase)

    Metamucil improved my bowel movements. I am 55, so at an age where this is a concern. Started having unfirm, messy bowel movements for 3 months, to extreme diarhea for 2 weeks, to constipation. Wanted to get back to as much of normalcy as I could. The really cute Metamucil commercials with Suzi Barrett motivated me to try it. I did, & my bowel movements kicked back in, firmer albeit soft stool. I switched to the Equate brand for now, 1/2 price of the Metamucil, & cost is a major issue for me right now. Much improved on the bowel issue.

  • Is it safe?
    Mary h (Verified Purchase)

    So I hate the taste texture of the sludge so I eat it like a pixie stick. Is this safe?

    • Thfgbfuijj

      DO NOT do that. that causes choking, take it with water. and plus if you don’t drink a glass of water with it, you won’t receive benifits from the fiber. fiber needs water to work.

    • Your Name

      I use the capsules.

    • Maribel (Editor)

      Hi Mary, its best to use as recommended, with water and meals, three times a day.

  • Strong flavored fiber supplement
    Pablo (Verified Purchase)

    I bought the orange flavoured metamucil the other day and the flavour is so strong I almost gag. I use a heaped teaspoonful in a medium glass of water but I think a much larger glass would be more appropreate followed by a glass of water to rinse out my mouth.

    • Anonymous

      Try drinking the orange flavored metamucil in orange juice

        Orange metamucil in sugar free almond milk- tastes like a cream-sicle 🙂

    • Emily

      If you’re not used to fiber intake, you may want to reduce the dose. Sometimes going from a low-fiber diet to a high-fiber diet too quickly can cause a constipation effect.

    • Maribel (Editor)

      Hi Cherry! Other users have reported similar side-effects. Please make sure to consult with your physician about this, especially since you’re are taking as instructed.

  • This is not for long term

    I really loved Metamucil at the beginning, but maybe one month after taking it daily (one glass per day), my body just seemed to get used to it and i don’t see any benefits…

  • Product Side Effects

    I just started taking metamucil and might stop, because it gives me such bad gas, too the point where i look much bigger than i am (I’m actually very thin) and the cramps are unbearable.. why might that be??? I only took one teaspoon in a HUGE glass of water and i drink a lot of water throughout the day…

    • kaye

      My doctor just told me to start taking Metamucil for constipation, and she said that it might initially cause bloating.

    • Maribel (Editor)

      Hi Keena, other users have mentioned feeling bloated. Please make sure to consult with your physician if this continues.

  • thickens up
    Adrienne (Verified Purchase)

    I Love the smooth formula. I noticed i can take it with just 8oz of water and i have a little more time befre it thickens up. Hate going to bed on an empty stomach so i just take some metamucil and i don’t want to binge at night. I have lost 5 pounds in a week!

    • Wendy

      5 pounds a week seems a little miraculous- are you exercising as well? I too am a evening binge eater and would like to use this to control it. I’d be happy with 2lbs a week loss, lol

  • it turns into a gel almost.
    Sarah (Verified Purchase)

    I just started drinking metamucil and it really grosses me out that it turns into a gel almost. Does this happen to anyone else? What am I doing wrong??

    • stacie

      You aren’t adding enough water. One tablespoon per day with one very large glass (think a large soda size from MCDs). Stir quickly. Drink quickly. Letting it sit will make it gel. The extra fiber and all the water will make you not hungry for a few hours. But really the extra fiber will help lower cholesterol if you need that also.

    • Robin

      If you cant chug it down quickly (which I have trouble with) between drinks keep stirring it quickly, by doing this it will not clump together.

    • Terry

      I just started using it. The only way I can digest it. The water has to be ice cold. And it does not get thick quick. If you I chug it down. But my daughter tried it mixed in water that was not cold. And it thicken her her, she said it was gross.

  • I just start Metamucil drink.
    Anonymous (Verified Purchase)

    If you put club soda in your metamucil drink it the club soda will hold the powder in suspension and not fall to the body. It makes a refreshing drink. No more gagging on the glug.

    • Anonymous

      I took a glass of water and put 3teaspoons of metamucul in it. After a kept peeing alot, and 3days later i do not feel nausaos anymore.

  • Metamucil does the best job.
    Elaine Martin (Verified Purchase)

    My husband and I have been taking metamucil for several years. We have tried other kinds but we feel metamucil does the best job. However, I tried Berry Burst and it is downright nasty. The after taste stays with me and is not at all pleasant. I will go back to the orange flavor.

  • Loved the product
    jeannie (Verified Purchase)

    I love the new Pink Lemonade Metamucil. From what I have read with South Beach is that metamucil does not speed up the fat metabolism…but it simply prevents you from dumping too much fat and sugar into your system/blood stream at such a fast pace. Thus, it helps in decreasing the insulin flucuation that ultimately leads to stored fat.

  • can metamucil keep cholesterol level under control?

    Because metamucil has a lot fiber, can metamucil keep cholesterol level under control if someone is borderline with their level of cholesterol?

  • I was told Metamucil is good to help you if your stool is too loose too. Am I correct?

    I was told Metamucil is good to help you if your stool is too loose too. Am I correct?? I go once normal then 3-4 times mushy. Will this help me?

    • Roy

      Metamucil will definitely help you with your problem. I know from experience.

  • the new berry flavor is absolutely awful.
    Betty Judy (Verified Purchase)

    I think Metamucil is really good and works well. Have used it for a number of years. But the new berry flavor is absolutely awful. It has a medicinal taste. Keep to the orange as you have really made it taste very good. I tried the other fiber Benefil and it does not get the job done.

    • Louise

      could anyone tell me if they experienced headaches taking Metamucil as I have major headaches and only since taking Metamucil but not sure if it’s caused by this would appreciate a reply thanks

      • Diane Grover

        I don’t have migraines when I don’t have time to mix and drink Metamucil before going to work. This has happened three times. There may be a correlation.
