In the diet industry, don’t mistake marketing for effectiveness. We dug deep into Benefiber side effects, ingredients, clinical research and customer service quality. Additionally, we examined hundreds of user comments and reviews. Then, we summarized and condensed to give you the info you need.
What is Benefiber?
Firstly, Benefiber is dietary supplement created to improve digestive health.  The only listed ingredient is wheat dextrin. Supposedly, the supplement can curb cravings with just two servings per day.  One of the benefits is that it’s available in portable, easy-to-use packets.
Novartis, the company behind Benefiber, has been around since 1996. Online retailers and local grocery stores sell the supplement. We like that it contains natural ingredients and the longevity of the company, but read on…
Price of Benefiber – “A Bit Too Much?”
Our first concern is with price of Benefiber. ” The active ingredient is made up of wheat dextrin, just like many other supplements on the market,” said our Research Editor. “This ingredient is widely available for a fraction of the cost; so why pay more than twice the cost?”
“I had seen commercials for Benefiber and thought I would give it a try – bye bye $20,” says a user.
Another buyer claims, “The American consumer is too stupid to notice that the unit cost per oz. is way higher than competitors.”
There’s not always an issue with money. We found a user that thought it well worth the cost, “Definitely worth the price to keep the fiber intake up!”
Another said something similar, “Benefiber had no taste, dissolved fast, and was sold at a great price.”
Poor Customer Service – “An Issue?”
If there are questions or comments about a company, it is important to have the option of reaching a customer service representative. We called Benefiber only to find we experienced a long wait and a less than friendly agent. Benefiber users report the same results. 
“When I called, they had me complete a lengthy questionnaire on the phone…when I insisted that I speak to a supervisor, after a lengthy hold, they agreed to send me [a] coupon,” offers a buyer.
“Their customer service sucks. They are not kind,” according to a caller.
There were quite a few complaints about the customer service department. We were unable to find anyone who had a positive experience.
We’ve found in our research that product issues, like poor customer service, are enough to hinder the long-term success of the supplement. If Benefiber is not there to support the buyer, this could be questionable. 
Is the Science There?
Benefiber claims the Healthy Shape option is “clinically proven”, but we found no research studies listed to support this statement. We read information supporting the use of fiber for mild appetite suppression, but there’s no reason to believe a branded supplement is more effective than a generic one. At DietSpotlight we need proof that a formula is the best option for weight-loss. If that’s not part of the plan, the dieter might as well turn and walk away.Also: read our Dietspotlight Burn Weight-Loss Kit review »
The Bottom Line – Does Benefiber Work?
Ahhh, now it’s time for the final take on this one – ready? We like the company’s long run in the supplement industry and all-natural source of fiber, but we don’t feel comfortable suggesting it because of the higher price and poor customer service support.  Based on some Benefiber reviews, we’re also a bit concerned with the “F” BBB rating.
If you’re ready to make those extra pounds disappear, we recommend a product with strong customer service support and an affordable price. You should also look for a formula comprised of proven ingredients.
Among the best products we’ve seen this year is one called Dietspotlight Burn. The compound consists of four ingredients in a proprietary blend with published research for support showing it can help raise metabolism and speed up fat loss. We found no reports of negative side effects and customer feedback on results reports dieters seeing great results.
Plus, the producers of Dietspotlight Burn are so confident the product will work, they’re offering a Special Trial Offer, positive sign.
Benefiber offers a source of fiber that mixes well in liquids and tastes like nothing. There is only one ingredient and the total fiber content is much lower than you'd expect. One serving contains 15 calories, 4g of carbohydrates, and 3g of fiber.
Benefiber Ingredients and Supplement Facts
Serving Per Container: Varies
|Amount per Serving||% DV|
Other Ingredients: None
We dove into the Benefiber ingredients to give you the details you need.
Wheat Dextrin is a carbohydrate  that is made by starch hydrolysis or glycogen.
What is it Supposed to Do?
If you take Wheat Dextrin  properly, it acts as a natural laxative. It can also help to suppress appetite because it is a form of fiber.
While researching about Wheat Dextrin, we found that many studies have been done on the relationship between it and weight-loss. Based on a study done by the Nutrients and Immune Function journal, they said, “The role of fiber in health has extended far beyond improved laxation, and includes benefits on risk factors for cardiovascular disease, weight management, immune function, and colonic health.”
In another two-part study from the journal, Nutrition Today, says the opposite. Part one first comes out and says, “Introduction of insoluble fiber (eg, wheat bran) or soluble nonviscous fiber (eg, inulin, wheat dextrin) has no significant effect on the rate of nutrient absorption in the small bowel because neither type forms a gel to alter the viscosity of chyme”, then follows up by stating, “Health benefits associated with fiber effects in the small bowel (eg, cholesterol lowering, improved glycemic control, satiety, weight loss) are a gel-dependent phenomenon, and the degree of benefit is proportional to the viscosity of the gelling fiber,” suggesting that because it is not gel-based, it did not work. 
As you continue to read to part two, they suggest the same thing by saying, “A recent comprehensive review of available clinical data concluded that resistant starch (soluble, nonviscous, fermentable; eg, wheat dextrin) had no significant effect on satiety or weight loss at physiologic doses. A yearlong study in 97 adolescents has been quoted as demonstrating weight loss for a ‘prebiotic’ fiber supplement (soluble, nonviscous, fermentable), but a closer look at the data shows that the prebiotic fiber group was not different from baseline for body mass index.”
We’re all about the clinical research and support. We see no reason why you can combine a fiber like Benefiber with a supplement like Dietspotlight Burn. The makers are offering a Special Trial Offer. Click above to learn more.
From time to time supplements need a closer look, like Benefiber, so we will put the spotlight on Benefiber ingredients. We’ll concentrate on potential side effects and clinical research. Additionally, we’ll pick apart dieter comments. Then, we’ll condense the info to give you the bottom line.
What You Need to Know
Benefiber is a supplement consisting of wheat dextrin. When you mix two teaspoons per day with water or your favorite beverage the product supposedly improves regularity. Increasing fiber may also help stave off hunger. Ease of mixing is one of the benefits.
The product, introduced in 1996 by Novartis, doesn’t include artificial ingredients, impressive. The supplement is available to purchase on the official website and through retailers. We like that Benefiber is readily available and that the company has been selling the fiber for close to 20 years, but read on…
Gas – “Not so Nice”
The first negative about Benefiber ingredients is that they may cause gas. “There’s nothing more embarrassing than squatting down to pick something up and…bam!,” said our Research Editor. “Some people can take extra fiber, but others just can’t.”
“That formula tends to give me gas,” said a consumer.
“I’ve had more gas and bloating lately, I think since I started…Benefiber,” said a user.
Blowing Up Like a Balloon?
Some comments from dieters say Benefiber ingredients cause bloating. “Causes bloat and if you are allergic to wheat…..can be very bad…..as I found out the hard way…..causing constipation and bloat to no end,” commented a user.
“The gurgling after-effects are pretty uncomfortable as is the bloating. I tried taking about 1/2 tsp in my coffee this morning and I went to the BR, but I still have hyperactive bowel issues,” stated a consumer.
“I started Benefiber today and do not feel well…bloated and a bit nauseated,” says a customer.
Our research concludes that something small, like bloating, could lead to a reduction in long-term success. If Benefiber ingredients cause side effects, there’s a concern.
The official Benefiber website claims it is “clinically proven”, but the company doesn’t provide published scientific research that connects the formula to weight-loss. We found studies showing wheat dextrin, the active ingredient in Benefiber, could potentially cause side effects. According to the Journal of Medicinal Food, “Differences in fermentation rate, gas production, and SCFA production observed for WD [wheat dextrin], PS, and inulin may affect…gastrointestinal tolerance. Soluble fiber supplements (eg, wheat dextrin, inulin) do not provide…clinically meaningful glycemic benefit.” At DietSpotlight, finding science to support claims is of the utmost importance. If there’s no science, we turn away.
The Bottom Line
Looking more closely at Benefiber gave us a definite conclusion. We like that Benefiber has been around for years and that the product doesn’t include artificial ingredients, but we can’t recommend it because there’s no direct link between this supplement and weight-loss. We’re also concerned about the occurrence of bloating and gas.
If dieters want to lose weight, we recommend a supplement with no harmful side effects and ingredients supported by published scientific research.
Dietspotlight Burn is one of the best products we’ve encountered this year. The supplement contains a four-ingredient proprietary formula, which studies have shown can help boost metabolism and promote fat loss. We can’t find comments about negative side effects and reviews on the web are highlighting people seeing excellent results.
The makers of Dietspotlight Burn are confident in the supplement, so they’re providing a Special Trial Offer, a great choice.

Benefiber Side Effects:
In a time where weight-loss supplements play a pivotal role in daily routines, it’s important to note that the natural solution isn’t always the choice without negative side effects. Each formula is different and each individual has a unique reaction, so while Benefiber side effects are few and far between, that doesn’t mean they don’t occur with some people.
Bloating is the uncomfortable feeling of being filled with gas or liquids. The tummy area may become distended and be accompanied by the regular feeling of needing to pass gas.
What causes bloating?
Bloating is very common and is often experienced after eating big meals. Overeating, consumption of rich and fatty foods and eating too quickly can all be causes of bloating. If there is an obstruction like scarring on the stomach, it can make it hard for food to pass through the digestive tract, causing bloating in some cases. 
Abdominal pain could be described as a cramping, dull, sharp or achy discomfort in the stomach area, between the pelvis and chest.
What causes abdominal pain?
There can be many causes for this symptom, including eating habits and certain medications. Virus, parasite, and bacteria can be factors as well. Any inflammation or irritation of the body’s organs (spleen, stomach, gallbladder, and liver) can cause abdominal pain.
Constipation is having fewer than three bowel movements a week, with feces being small, dry, and hard, making them difficult to pass. 
What causes constipation?
When stool travels slowly through the digestive tract, the colon absorbs too much water, drying it out and leaving it harder to pass. Neurological issues could be a factor, affecting nerves in the muscles of the colon and rectum which contract to move stool through the intestines. Other causes are low liquid or fiber intake, medications or lactose intolerance.
Diarrhea is the condition of having loose and watery bowel movements that occur at least three times a day. If this symptom persists, it can lead to dehydration and increased heart rate.
What causes diarrhea?
The most common causes are infections, parasites, and bacteria. Irritable bowel syndrome (IBS) can be a factor, as well as inflammatory bowel disease, and inflammation of the distal colon (ulcerative colitis).
Benefiber side effects are fairly uncommon, but there have been some reports of constipation, abdominal pain, diarrhea and bloating. In order to curb your chances of any future negative reaction, it’s always a good idea to talk with a doctor before taking any supplement, especially if you are pregnant or nursing, under the age of 18, are taking any prescription medications, or have a pre-existing medical condition.
While side effects from fiber supplements are rare, there’s a chance adverse reactions could occur. One that’s not connected to harmful side effects and contains clinically-tested ingredients shown to help promote weight-loss is one called Dietspotlight Burn. Click above to learn about the sample offer.
We’ve heard the rumblings about the benefits of dietary supplements, like Benefiber, so we decided to pay a bit more attention to Benefiber side effects. (We extend an invitation to read our full Benefiber review.) Our research will focus on ingredients and clinical studies. We’ll then analyze dieter comments. We summarize the info to give you the bottom line.
What You Need to Know
Benefiber is a dietary supplement containing wheat dextrin. Dieters can mix the powder in water and consume it three times per day, which supposedly increases weight-loss. One of the benefits is that the product is easy to mix.
The product, introduced as a dietary aide by the GSK Group in 1996, doesn’t contain artificial ingredients, a good choice. Dieters can shop for Benefiber at local stores and online. We like that the company has been in business for decades and that we located some positive customer comments, but read on…
Rash – Leaving You Feeling Red and Itchy?
The first negative aspect relating to Benefiber side effects is skin rashes, according to reviews. “The supplement market is hot right now,” said our Research Editor. “If a simple product like this can’t give consumers what they want without leaving them itching, that’s not a good sign.”
“I have been taking Benefiber for just over a week…suddenly my legs have developed a rash of sorts-just on the backsides-not pimples, but a red, flat rash. Itches a little,” stated a user.
“Significant gas and a continuing itchy rash all over my back,” said a customer.
According to customer comments, Benefiber ingredients caused bloating. “I started Benefiber today and do not feel well…bloated and a bit nauseated,” commented a dieter.
“It gave me a bloated feeling, burping, flatulence, and did not stop any food cravings. It is a waste of money,” reported a user.
“Benefiber causes my stomach to bloat and become so tight. I get so bloated that my BM will not come out for about four hours after I am awoken in the middle of the night with cramps and pain,” said a customer.
Based on our research, if a supplement has one issue, like causing bloating, there’s a chance you won’t succeed in the long-term. If Benefiber side effects are a concern, dieters should walk away.
When we visited the official Benefiber website, we noticed a wealth of information relating to the benefits of the supplement, but the company doesn’t provide evidence linking the formula to weight-loss. After further review, we noticed that the amount of fiber listed may not be a sufficient amount. According to the Journal of International Medical Research, “Dietary fiber is widely recognized to have a beneficial role in overall health, but only at adequate levels (25 – 38 g/day for healthy adults).” The recommended serving of Benefiber is 12g per day. At DietSpotlight, finding science to back claims is important. If there’s no research, there’s a problem.
The Bottom Line
After scrutinizing the information on Benefiber, here’s our conclusion. We like that the company has been around for quite some time and that we located some favorable reviews, but we can’t recommend it because of weight-loss claims aren’t supported by scientific research. Plus, there’s concerns that Benefiber ingredients could lead to bloating and rashes.
If you’d like to lose those extra pounds, we recommend going with a supplement with no side effects. One that is supported by scientific research.
Of the best supplements we’ve researched this year is one called Dietspotlight Burn. The product contains a formula which includes a four-ingredient proprietary blend, shown in published clinical studies to help boost metabolism and ignite fat loss. We can’t locate anyone talking about negative side effects and from the comments on the web, people are seeing excellent results.
In addition to the makers of Dietspotlight Burn having confidence in the supplement, they’re providing a Special Trial Offer, impressive.
Side effects are not common in those who take Benefiber, but a few have been reported by consumers. While these do not speak for the majority there is always risk when taking any dietary supplement.
“My wife and I started using Benefiber three weeks and my wife stopped using it after a week, I am stopping today because of so many stomach pains that started after using Benefiber.” Glenn
“I have been noticing a lot of rumbling in the tummy. Loud and kind of embarrassing. Also I have noticed that I get an upset stomach after eating.” Stephanie
“Took benifiber once last week and haven’t stopped cramping.” Eric
“I started benefiber 5 day ago I been feeling gas bloating.” Sherla
We are all for limiting side effects when taking any dietary supplement, and have noticed that Benefiber reviews incredible with very few grievances.

Previous Benefiber Review (Updated May 22, 2014):
What You Should Know about BenefiberThe Food Nutrition Board has recommended that Americans consume at least 38 grams of dietary fiber each day for men and 25 grams for women. However, it is said that Americans only consume about half of the recommended daily amounts of fiber. Benefiber touches on this on their official site. Most of the fiber in our diets comes from plant sources and has been proven to play an important role in normal bowel function. Desirable sources of soluble fiber include oats, fruits, vegetables, dried peas, and beans as well as legumes. Insoluble fiber does not get digested by the intestines and increases the rapid transit of food out of the body which promotes regularity and softens stools. A clinical study has been done to test this. It has been reported that many people take fiber additives to aid in weight loss. Diets that are high in fiber have been said to improve the body's ability to rid the body of waste thus shortening the length of time that food remains in the body thus possibly promoting weight loss.
List of Benefiber IngredientsThe active ingredient found in Benefiber is Wheat Dextrin. Wheat Dextrin is a natural soluble fiber which is marketed as a gluten-free product due its low levels of gluten, only 10 ppm of gluten is found in Wheat Dextrin.
Product FeaturesEach serving of the Benefiber Ingredients is said to contain 3 grams of fiber. Benefiber comes in several forms such as chewables, caplets and powders, including the new berry flavored powder which contains calcium. Fiber is considerably malleable as Metamucil also comes in several forms. The regular powdered form of the supplement is marketed as "sugar free" and taste free" and can be virtually added to any food or drink and promises not to change the taste, texture, or consistency. Companies employ this trend of diverse options as is the case with Usana Essentials Multivitamins or Usana Nutrimeal. In fact, the official Benefiber website contains a list of recipes which contain Benefiber in its list of ingredients. An FDA investigation leaves us a bit concerned though. There are soups, sauces, and dips, salads, main dishes, desserts, and snacks as well as smoothie drinks. In addition, Benefiber promises not to have the normal "gritty" texture found in many over the counter fiber supplements. The official website even posts tips on how to increase your daily intake of fiber through adding certain types of foods to your diet.
Advantages of Benefiber
- Each serving of Benefiber adds 3 grams of needed fiber to your diet.
- Benefiber is all natural and contains no potentially harmful ingredients.
Disadvantages of Benefiber
- Some reported side effects associated with taking Benefiber include flatulence, gastrointestinal pain, discomfort, diarrhea, nausea, stomach upset, as well as stomach pressure resulting in a "full" feeling. (More on Benefiber Side Effects)
- Benefiber does not promote thermogenisis within the body to aid in weight loss.
- Benefiber does not contain a fat burner in its ingredients.
ConclusionMost of the processed food that Americans consume has been virtually stripped of any fiber and nutritional content and dietary fiber has been shown to play a role in the body's ability to regulate its digestive system to a more "normal" function which helps the body to "move" food through the digestive tract at a faster rate. This trend gave rise to other health food supplements like SafSlim or V8 Diet. This may in fact aid in weight loss however a diet rich in foods that contain high levels of fiber are a much better source. However it must be said that Benefiber may give the same desired results without the extra calories.
Benefiber Scientific Abstracts:
Wheat dextrin is a type of fiber that is taken from wheat starch and commonly used to add fiber to foods that are processed. Evidence proposes that soluble fibers aid in the regulation of the digestive system, could boost micronutrient concentration, steady blood glucose and reduce serum lipids. It could also put a stop to gastrointestinal illnesses, and play a part in preventing cardiovascular disease. 
Modified Food Starch
Modified food starch was established as an additive to offer the desired texture, thickness, and storage capability. They are mostly used in strained and junior foods, and sometimes infant formulas. There is concern that modified food starches are being used by the food industry for infants and children and the need for more data in regards to the bioavailability effect on nutrient concentration, intestinal alterations, and toxic, mutagenic, and carcinogenic effects are crucial. The addition of modified food starches ought to be used cautiously and scarcely. 
Vitamin B6 (Pyridoxine Hydrochloride) organically appears in a lot of foods, is added to others, and made accessible as a nutritional supplement. It is essential for the production of neurotransmitter serotonin and norepinephrine as well as for myelin development. An absence of pyridoxine in adults mainly affects the peripheral nerves, skin, mucous membranes, and the blood cell system. It will also affect the central nervous system in children. This typically occurs in those that have uremia, alcoholism, cirrhosis, hyperthyroidism, malabsorption illnesses, and congestive heart failure. Vitamin B6 is naturally found in cereal grains, legumes, carrots, spinach, peas, potatoes, milk, cheese, eggs, fish, liver, meat, and flour. 
Folate (vitamin B9) is found in many different foods, such as vegetable (particularly leafy greens), legumes, cereals, eggs, and fruit. Folate is necessary for the development of red and white blood cells in bone marrow, changing carbohydrates to energy, and producing DNA and RNA. Some possible health advantages of folate consumption are reduced risk of birth defects, decreased risk of depression, and healthy heart support. Plenty of folic acid is necessary during pregnancy to defend against miscarriage and neural tube deficiencies in the fetus. Enhanced chances of depression and little response to antidepressant treatment have been associated with low folate. High levels of homocysteine are linked to greater chance of cardiovascular disease, and it has been found that folic acid supplements can lower homocysteine levels. Therefore it is suggested that folic acid decreases the chance of heart disease. 
A study was conducted to measure the effects of sodium citrate intake on the metabolic reaction to exercise and performance of a 1500-m competitive run in females that are trained middle-distance runners. The study was done double-blind style and found that sodium citrate encourages a boost in retaining water before exercise and could alter carbohydrate metabolism in high power running, but did not increase the performance of female middle-distance runners in a 1500-m run. 
Beverages that contain citric acid could be helpful for the nutrition treatment of calcium urolithiasis, particularly in those with hypocitraturia. Citrate (citric acid) an inhibitor that naturally occurs in urinary representation accomplishes beneficial urinary citrate absorption and is a clinical goal in the therapeutic management of calcium urolithiasis. Beverages that contain citric acid enhance the overall amount of urine, decreasing permeation of calcium and additional crystals, and could also improve urinary citrate emission. Lemon and lime juices are excellent sources of citric acid.
