You may be surprised by what I say in this Metamucil review. We at DietSpotlight took an in-depth look at this product, examining the ingredients, side effects, customer service and clinical research. We additionally focused on all sorts of user comments we found all over the web. Lastly, we summed up all of the facts and feedback we discovered to give you the info you need.
What is Metamucil?
To start with, Metamucil is a line of fiber supplements made by Proctor & Gamble. These products are available in common grocery stores and supercenters. While the powders are probably the most popular, there are also capsules, bars, wafers and probiotics. The purpose is to help you maintain digestive health, encourage regularity and promote a healthy immune system. They may also help you feel less hungry between meals, lower cholesterol levels and regulate healthy blood sugar levels. It can be used up to three times daily, along with meals or in between meals. The primary ingredient is Psyllium Husk (a type of natural fiber).
Metamucil has been available since 1934. These products are easy to come by in local stores and there is plenty of customer feedback posted online. Also, there are sugar-free options available, but read on…
Bad Taste – “Something to Consider?”
First off, we looked at Metamucil ingredients and the flavor. “We sorted through a lot of customer reviews and noticed that there are numerous complaints regarding the actual taste. Naturally this is concerning because people are less likely to stick with it if that’s the case,” says our Research Editor.
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. Better off just getting your fiber the old fashioned way through fruits and veggies, or take the pill form instead. What a waste of my money.”
“Tastes absolutely terrible. 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.
Another shared, “It works for it’s intended purpose and tastes good.”

Adverse Effects – “Another Concern”
Quite a few customers have complained about side effects from Metamucil. In fact, one user commented, “OMG this stuff is aggressive! I have had the worst side effects from this, severe stomach pain, bloating, gas pains, nausea while using this product.”
Another customer mentioned, “Metamucil gave me a lot of cramping. The day after I would take it, I would go and it would be painful, irritating and cramps would last for about 20 minutes.”
Not surprisingly, there are people who saw this as being gentle, not harsh.
“Gentle, and is effective, for me, if taken first thing the a.m. with 8 oz. of water,” was one comment.
Others saw changes for the better, “ It gives me enough fiber that my intestinal episodes have been minimized.”
According to our extensive research, if there is some particular part of a diet supplement that is quite bothersome (bad taste, serious adverse effects, no real science) the odds of lasting weight-loss are not good. This means if Metamucil does cause serious adverse effects in numerous people, this could be problematic.
The Science – “Legit?”
From what we could gather, there are some clinical studies that support Metamucil as a supplement for lowering cholesterol levels and promoting regularity. On the other hand, there is no solid link between it and long-term weight-loss or fat reduction. At DietSpotlight, we prefer to see published science that supports the product and we didn’t this time.
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 some positive comments we saw about it online. However, we have some reservations about it because it’s not backed by science as a fat-loss product. Also, we’re concerned about the adverse effects and less-than-savory taste.
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 in 2016 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.

What You Should Know
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. 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.
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
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.

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.

Metamucil Ingredients and Supplement Facts
Serving Size: 1 Rounded TSP
Serving Per Container: 72
|Amount per Serving
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.
