You may be surprised by what I say in this Metamucil review. We at DietSpotlight took an in-depth look at the ingredients, side effects, clinical research and customer service quality. Additionally, our attention turned toward to hundreds of user comments and reviews. Then, we summarized and condensed to give you the info you need.
What is Metamucil?
To start with, Metamucil is a line of fiber supplements. The ingredients are psyllium husk, vitamins and minerals. It can be used three times daily; in-between or with meals. Supposedly, it helps you maintain intestinal health , encourage regularity  and satiety. 
Metamucil has been available since 1934. These products are sold online and at local grocery stores. We like that it’s affordable and contains a few natural ingredients, but read on…
The Taste of Metamucil – “Not Good?”
The first concern was that Metamucil ingredients weren’t flavorful. “The purpose of the product line is to support overall health via a healthier intestine and colon, appetite suppression and regularity,” says our Research Editor. “Though these are not the most exciting benefits, they are necessary and clinically supported. However, the taste could bring a halt to everything if the dieter can’t drink the fiber.”
According to one customer, “I don’t know how people drink this stuff on a daily basis. The texture is awful, it feels slimy, and the aftertaste makes me ill.”
“Has a very odd aftertaste that actually made me gag,” said another user.
For some, the taste was near that of fruit juice.
“Taste good. Taste like orange juice,” said one person.
Side Effects – “Concerning?”
According to Metamucil reviews, side effects were a concern. It is clinically proven for some users who start taking fiber to experience bloating , gas and abdominal pain. You have to take it slow and start out with a small amount and titrate up to the recommended 25-30g a day . An amount few people in the United States are meeting.
One user commented, “I have had the worst side effects from this, severe stomach pain, bloating, gas pains, nausea while using this product.”
Another stated, “Metamucil gave me a lot of cramping…would last for about 20 minutes.”
Not surprisingly, there are people who saw this as being gentle.
“Gentle and effective, if taken first thing the a.m. with 8 oz. of water,” reported a dieter.
According to our extensive research, if there is some particular part of a diet supplement that’s concerning, like being the cause of negative side effects, long-term success may be limited. There’s an issue if Metamucil causes adverse reactions.
The Science – “Research-Based?”
We like that there’s plenty of science out there to support the use of fiber for overall health and wellness. Diabetics , dieters , children  and adults  all need it to help control blood glucose levels, support colon health and satiate hunger. With that said, there’s nothing that proves Metamucil is the only brand that offers these benefits. Here at DietSpotlight we love to see support published in trusted journals and we have that this time, but it doesn’t prove you have to buy this specific product.Also: read our Leptigen Weight-Loss Kit review »
The Bottom Line – Does Metamucil Work?
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 regulate blood glucose, 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 supplement 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 Leptigen. This supplement contains a blend of four ingredients, which have been shown via clinical testing to possibly help improve fat loss and ignite metabolism. Furthermore, user comments found on the internet show people are seeing solid results.
Also, the makers of Leptigen are so confident in their product they’re offering a Special Trial Offer, which is a good sign.
Previous Metamucil Review (Updated January 2, 2014):
What is Metamucil?
Would be dieters are always looking for the elusive magic pill that will allow them to eat everything they want and still lose weight. Unfortunately to date, no such pill exists. There is no shortage on commercials and print ads that promote adding fiber to your diet. One doesn't have to be a rocket scientist to see that a healthy digestive system will be more efficient at eliminating excess waste. According to the manufacturers, diet products that contain high amounts of fiber can help increase satiety making you feel fuller. The best way to increase your fiber is to eat foods that have a high fiber content. Perhaps eating fiber gets easier with Benefiber as it suggested to improve digestive health, and curb cravings. Sounds simple enough right? Unfortunately research suggests that most people's diets are deficient in fiber. This is where a supplemental form of fiber such as Metamucil may be useful. Metamucil is sold as a dietary supplement and as a laxative not a weight loss product, however many consumers have begun to use Metamucil as an aid to weight loss.
Ingredients Used in Metamucil
Metamucil comes in tablets, wafers and in powder form. The main ingredient is fiber. However, fiber isn't the only thing on the Metamucil Ingredients list
Product Features - Details About Metamucil
The whole concept of taking Metamucil as a weight loss aid is that when taken, it gels in the stomach and helps dieters to take in less food which results in weight loss. Additionally, Caralluma Fimbriata, is a natural cactus plant used for majority of products found in the market, it is suggested to reduce hunger, evidently decreasing appetite.
- Metamucil is comes in many forms to fit various lifestyles.
- Metamucil may be act as an aid to digestion and assist with constipation problems.
- Taking excessive amounts of Metamucil can result in a vitamin deficiency.

- Some find the flavors unappetizing. (See reader comments.)
- There is no evidence that Metamucil has an effect on reducing body fat or that taking Metamucil will increase the rate at which the body metabolizes fat.
Our Conclusion on Metamucil
Would be dieters looking for a "quick fix" and who do not want the commitment of eating a healthy diet rich in fiber will likely turn to such products as Metamucil for weight loss. However it should be noted that there is insufficient evidence to prove that Metamucil when used as a dietary supplement will work as an effective weight loss aid. Nor does the evidence suggest that Metamucil will increase the rate at which the body metabolizes body fat. Metamucil may act as an aid to better digestion and assist with constipation. Although constipation is always a risk factor when taking most dietary supplements, Phentermine harbors weight loss by decreasing the appetite with pills on the go, and it's note-worthy cause is it can possible help improve long-term weight loss. Taking excessive amounts of Metamucil can result in a vitamin deficiency in the body and many consumers have developed a dependency on laxatives and stool softeners. The product is available for sale at many online retail sites which carry vitamins and supplements. Many local grocery and drugstores may carry Metamucil as well. Metamucil comes in many forms, is reasonably priced and affordable for the most consumers.

Metamucil User Tips:
Over the years, we’ve discovered that Metamucil users have something to say. After examining thousands of comments and reviews, these are some of the best tips we found to help you learn more about this product.
“I usually take this after dinner mixed with a large glass of water around 7pm in the evening. Then I’ll drink another glass of water. Always cold water and at least two to three hours before going to bed.” Richard
“A good rule of thumb is not to take fiber at the same time as other medicines as they may bind to the fiber and not get absorbed. Take your other medicines at least 2 hours apart from Metamucil.” Noramn
“A big part of the benefit you receive from Metamucil is by virtue of its course, somewhat gritty texture. A fiber product that “dissolves completely” in water is not going to suddenly transform into a gangbuster in your guts. Sorry if you find that disappointing.” Levi
“I actually like the consistency of it and prefer to let it sit a few minutes to thicken. I also drink a lot of cold water during the day because I don’t think it’s a good idea to take something like this without a lot of water to keep it moving along.” Mark
“One word of advice…after mixing in the liquid, don’t let it sit or it will get thick and you won’t want to drink it. Drink it down as soon as you stir it.” John
“The aspartame in the Metamucil gave me headaches, so I had to switch to the sugared variety.” Toni
“Consider starting with a small dose and work up to the recommended dose. Too much at once can hurt…bad cramps.” Patricia
Metamucil Scientific Abstracts:
Psyllium substantially elevated the apparent thickness of watery stool extract, wet and dry weight of the stool, and stool moisture. In conclusion, there is a component of psyllium that is not fermented, as opposed to other viscous fibers which ferment entirely in the colon. This gel substance delivers lubrication which triggers a propulsion of the contents in the colon, producing stool that was moister and bulkier than most of the other bowel-regulating fiber sources. 
There was an average decrease of total and high-density lipoprotein cholesterol by 6.4% and 9.3% within the normal group following supplementation of the seed. Following both systems, there were no effects on fecal bile acid excretion within the normal participants. Ileostomy bile acids elevated (25%) following supplementation of the seed and no effects on cholesterol concentrations were observed. The results indicated that psyllium seed may be more essential than the husk itself in decreasing serum cholesterol. This cholesterol-lowering trait was not mediated by elevated fecal bile acid loss and raised ileal losses of bile acids may be recouped by heightened reabsorption within the colon. 
Amounts of fecal energy (544, 662, 737 kJ per day), nitrogen (1.5, 1.8, 2.1 g per day), resistant maltodextrin (0.3, 0.6, 1.2 g per day), and total carbohydrate (11.1, 14.2, 16.2 g per day) elevated with a raised dose (0, 25, 50 g) of resistant maltodextrin (P < 0.0001). There were no differences in fat excretion within treatments. Metabolizable energy of resistant maltodextrin was 8.2 and 10.4 kJ/g. The net energy value of resistant maltodextrin was -8.2 and 2.0 kJ/g for the 25 and the 50 g per day resistant maltodextrin doses. Both of the resistant maltodextrin doses elevated fecal wet weight (118, 148, 161 g per day; P < 0.0001) as well as fecal dry weight (26.5, 32.0, 35.8 g per day; P < 0.0001) in comparison to the placebo. Fecal bacteria total counts were raised by 12% for the 25 g per day resistant maltodextrin dose (P = 0.17) and by 18% for the 50 g per day resistant maltodextrin dose (P = 0.019). Resistant maltodextrin consumption was linked with a statistically substantial elevation (P < 0.001) of different operational taxonomic units resembling ruminococcus, lachnospiraceae, eubacterium, faecalibacterium, and holdemania, incriminating resistant maltodextrin in their growth within the gut. The findings deliver empirical data which is pivotal for food labeling regulations regarding resistant maltodextrin’s energy value and indicates that resistant maltodextrin elevates the bulk of stool by improving nitrogen and carbohydrate excretion as well as growth of certain microbial populations.

Metamucil Side Effects:
When adding a product to your system you should always be aware of all possible side-effects. Users of Metamucil (psyllium) have named the following adverse experiences when taking the fiber supplement, though we were hard-pressed to find these.
Nausea is a state of stomach discomfort and is usually accompanied by a strong urge to vomit. It is when the stomach feels queasy or unsettled. Nausea can be so uncomfortable that it impedes people from carrying out normal daily activities.
What causes nausea?
There are many potential causes of nausea including concussion or ulcer. Less severe causes include motion sickness, spicy food intake, changes in diet and adverse reactions to medications, both prescribed and over-the-counter. 
Bloating can be difficult for experiencers to describe but typically is found to be a sensation of fullness, burning, and strong discomfort in the abdomen. Sufferers may see and feel a swelling in the stomach or intestines. Bloating may also result in significant belching or flatulence.
What causes bloating?
Most cases of bloating are brought on by issues related to dietary activities. Foods and medications can cause bloating as can the swallowing of air, or eating too fast. Problems can also occur with products that alter the normal digestive process.
Loose, watery, uncontrollable bowel movements are known as diarrhea. Diarrhea is usually accompanied by cramping and discomfort in the abdomen and occurs when too little water is absorbed in the intestine, or waste is pushed out quickly, as is the case with laxatives.
What causes diarrhea?
There are several known origins for diarrhea such as ulcers, bacterial and viral infection, and colitis. Less severe cases are brought about by food poisoning, stress, anxiety, the consumption of medicines, both prescription and over-the-counter.
Created by acid reflux (which is the traveling of stomach contents back up into the esophagus), heartburn is a sensation in the lower chest of burning, aching or sharp pains. Heartburn can be acute or chronic, known as gastroesophageal disease. The pain is located under the breastbone and is increased when lying down or bending over.
What causes heartburn?
Foods that don’t agree with a person’s stomach, such as spicy and gassy foods, can cause heartburn. Other factors include obesity, smoking and issues with fiber or salt.
Metamucil is comprised primarily of psyllium and can bring unwanted side effects for some users. We always suggest checking with your doctor before using a fiber supplement like Metamucil just to curb any chance of negative issues.

“This product gave me too much gas.” Colene
“Gave my wife and I severe headaches.” TJ
“It made me sick to my stomach each time I used it.” Lois

Metamucil is a fiber supplement that's been around for decades. It's available in powder and capsule forms. The drink mix claims to be sugar-free, but there is maltodextrin in the formula. This ingredient is processed just as fast as glucose and is often used in candy. Each serving supplies 3g of fiber.
Metamucil Ingredients and Supplement Facts
Serving Per Container: 72
|Amount per Serving||% DV|
Other Ingredients: Citric acid, natural and artificial orange flavor, aspartame
We dug deep into the Metamucil ingredients to provide you with the specifics.
First off, psyllium husk is essentially a form of fiber. It comes from the plantago ovata plant. The seed husks are used to make this ingredient. It’s commonly used in all sorts of supplements.
What is it Supposed to Do?
Put simply, psyllium husk is supposed to help promote regularity. Therefore it may help treat constipation. When combined with water, it has a bulking effect. This in turn helps encourage bowel movements. It also makes stool easier to pass. It may even lower cholesterol and blood sugar levels.
According to the University of Maryland Medical Center, “The soluble fiber found in psyllium husks can help lower cholesterol. Psyllium can help relieve both constipation and diarrhea, and is used to treat irritable bowel syndrome, hemorrhoids, and other intestinal problems. Psyllium has also been used to help regulate blood sugar levels in people with diabetes.” This fiber can also help suppress appetite, which may assist some with weight-loss.
Maltodextrin is a polysaccharide. It’s commonly added to foods, and it’s made from starch.
What is it Supposed to Do?
Well, Maltodextrin is often added to foods as a sweetener. It typically comes from corn or wheat. It’s simply used as a thickener, filler or flavor enhancer.
There are no clinical studies that support Maltodextrin for health benefits. This ingredient is not linked to weight-loss at all. However, it may increase your chances of type 2 diabetes and weight gain.
To begin, Citric Acid is taken from citrus fruits. It is also naturally produced in the body. This is because it’s needed for producing energy. It’s often added to foods and soft drinks.
What is it Supposed to Do?
Citric Acid is often added to pharmaceutical products and soft drinks as a preservative or flavor enhancer. It can be found in all sorts of meat products, jams, frozen foods, gelatins and canned vegetables. It also aids with mineral absorption and provides antioxidants to combat free radicals.
One study from clincialchemistry.org showed that “Dietary citric acid enhances absorption of aluminum in antacids.” This in turn makes the products more effective. However, there is no connection between citric acid and weight-loss.
One that has caught our attention is Leptigen. It contains clinically-tested ingredients and has been shown to help accelerate metabolism and ignite fat loss. To learn more about it, click above.
We’ve heard a lot about Metamucil fiber supplement, so we decided to focus mainly on Metamucil ingredients. We’ll analyze the formula, taking into consideration the formula and clinical research. We examined hundreds of consumer comments in forums and on websites. We then summarized the info to give you the bottom line.
What You Need to Know
Metamucil is a fiber supplement containing psyllium husk, sucrose and vitamins. The recommended serving is one to two rounded teaspoons per day, which supposedly improves digestive health and suppresses appetite. One of the benefits is it’s easy to mix.
The product, introduced in 1934 by G.D. Searle and now operated by Proctor and Gamble, doesn’t appear to add artificial ingredients, a good choice. Customers can shop for it at local stores and online, but not from the official website. We do like that we found some positive customer comments and the length of time the company has been in business, but read on…
The first concern about Metamucil ingredients is stomach pains. “Fiber is the perfect addition to a healthy diet,” said our Research Editor. “Sometimes it can be a little overpowering if the dieter takes too much at one time.”
“OMG This stuff is aggressive! I have had the worst side effects from this, severe stomach pain, bloating, gas pains and nausea while using this product. I have never been that sick to my stomach like that for days with no real relief,” reported a dieter.
“I just started taking Metamucil and might stop, because it gives me such bad gas, to the point where I look much bigger than I am (I’m actually very thin) and the cramps are unbearable,” said a user.
Based upon consumer comments, Metamucil ingredients aren’t flavorful. “Tastes absolutely terrible. Has a very odd aftertaste that actually made me gag,” stated a consumer.
“The texture is awful, it feels slimy, and the aftertaste makes me ill,” commented a consumer.
“Most of all it tastes HORRIBLE! It’s gritty and revolting,” said a dieter.
When we review supplements, our research shows us that any portion of the ingredients causing concern, such as taste, could reduce long-term success. If Metamucil doesn’t agree with your palate, there’s a problem.
There’s a wealth of information relating to the benefits of Metamucil on the official website, but studies linking fiber to weight-loss are not that impressive. The ingredient can slow down digestion and leave the dieter feeling fuller, but when you’re used to overeating that may not be enough to help you eat less. At DietSpotlight, finding published studies supporting claims is imperative. If the research is not strong enough, that’s an issue.
The Bottom Line
After completing our review, we’ve come to a decision. The positives include the length of time the company has been in business and we found some favorable customer comments, but we can’t recommend it because the effect on hunger may not be strong enough to help all dieters lose weight.
If you want to lose more pounds, we recommend going with a supplement that has ingredients backed by published clinical research, with no reported side effects.
One of the best supplements we reviewed in 2016 is one called Leptigen. The formula consists of a four-ingredient proprietary blend, shown in published scientific studies to increase fat loss and ignite metabolism. There’s no one talking about negative side effects and reviews on the web highlight people seeing excellent results.
The company that makes Leptigen is providing a Special Trial Offer, a good sign of confidence in the product.
