Fiber Benefits

Good health starts from the food we eat and it is true because the food choice is a crucial factor that will affect our overall health and it is better to be mindful about what we put in our body since it will be reflected on the outside, especially in a prolonged time. Health is the most important aspect we need to take care of, not only because being sick is painful but also because it will need a lot of money to cure while we can’t be as active and productive as before.

Diet often help people to support the healing of their illness and curing some light health issues as well, one of the most often being irregularities. Our body will feel better with whole foods options and a regular visit to the bathroom but to achieve this we have to consume the right food options as well and the key here is fiber. We are most people are familiar with this nutrient but not many seem to be aware of its benefits.

The most well-known benefits of high fiber diet is the regular bowel movement especially for the roughage type of fiber like strawberry seeds and wheat bran because it helps move things along the intestine and prevent constipation. Another benefit of fiber is it will help normalize blood glucose more specifically the gummy, gelatinous type of fiber like oats and kidney beans. There is a recent study that suggest fiber may be beneficial for treating people with syndrome X or insulin resistant condition which cause obesity.

Fiber Types

Before you go to do some grocery shopping, it is better to know what type of fibers are categorized so we can shop accordingly. There are two types of fiber; soluble and insoluble fiber. The soluble fiber is the type that dissolves in water and will form a gel-like material which is great to help lower blood cholesterol and glucose level. It can be found in oats, peas, beans, apples, citrus, carrots, barley, and psyllium in which you can check on our Dextrin Vs Psyllium.

The second is insoluble fiber that promotes the movement of material through the digestive system and this is the one beneficial for your regular bowel movement because it will increase stool bulk to stimulate bowel movement thus, people who struggle with irregular stools should consume this type of fiber. It can be found in cauliflower, green beans, whole wheat flour, and potatoes.

About Miralax and Benefiber

It is always better to get the daily fiber from your diet especially from whole foods because they will be great for your overall health, not just for the fiber content yet, we also understand that sometimes we can’t help but have to choose unhealthy diets and at certain times develop some issues like constipation. This is why there are so many fiber supplements out there offering a convenient way to fulfill your daily fiber intake goal with different purpose as well as different fiber types.

If you are in the market for a convenient solution which is great as a supplement to the diet without having to be extra selective about the food options, Miralax and Benefiber are two great choices to go. They are and equally popular fiber options out there similar to Citrucel but not unnecessarily the same because the former is designed to help people dealing with their irregular bowel movement or those who are currently struggling with constipation and want to find a quick solution.

Benefiber on the other hand, is marketed as a fiber supplement thus, rather than a solution for constipation, in our opinion this fiber is better for people who are having a goal to consume an ideal amount of fiber everyday. Benefiber itself is a brand of several fiber supplements including the chew tablet in case the regular version is not as fun to consume. Another unique thing about this brand is that it promotes the fiber as prebiotic and while it can be confusing, we will talk about it in a bit.

Coming back to Miralax, this fiber solution is very similar to Benefiber but as it has been mentioned above, the solution is marketed as a constipation solution and the catch here is it will act gently in your gut. We have been using various laxatives in the past and many of them are not only ineffective but also very painful to endure because they cause a stimulation on the bowel to push the stool and it is very uncomfortable, especially if you are not at home the time it takes effect.

Miralax and Benefiber Form

Laxatives and fiber supplements are coming in varying form to ease the user taking the solution conveniently or just to make sure the product is appealing to consumer but both Miralax and Benefiber are similarly coming in a powder form which is easy to dilute in water. The reason why we prefer this type of fiber is because it doesn’t contain and flavorings and colorant that some people are avoiding. We can also mix them with just any water for they won’t affect the taste.

Miralax has this bottle compartment which is ideal to be used in the house but if you are working outside, there is the sachet version for a more convenient. Benefiber is the same with its canister and stick package but if you want an easier to take supplement, we recommend the chew tablet from this brand. However, it has colorants and flavorings in mixed fruit flavor but they are sugar-free.

Miralax and Benefiber Ingredients

The first thing you may want to know about a solution is their main ingredient and starting with Miralax, this gentle laxative is made from Polyethylene glycol or Rx PEG 3350 which is more familiar being prescribed by your doctor. This fiber is included in a class of medications called osmotic laxatives. On the other hand, Benefiber is Wheat Dextrin which is soluble fiber and often used to enrich one’s daily fiber intake rather than a laxative on its own.

Miralax and Benefiber Mechanism 

For those who are not familiar yet with osmotic laxative, this type of solution is called so because it works by drawing water into the intestines and as the name suggests, it is not the best solution for those who are dehydrated. This mechanism then result in water to be retained with the stool thus, increase the number of bowel movements as well as soften the stool so it can pass easier through your intestines.

Wheat dextrin in Benefiber is also helpful to promote regular bowel movement but while the dextrin itself is soluble fiber, its mechanism is a little bit different from PEG 3350 because it also add bulk to the stool. The fiber will draw water to your intestines and also bulking the stool due to the fiber content and it will help stimulate bowel movement to prevent constipation. Wheat dextrin has gluten in it but Benefiber claims it is less than 20 ppm, which is why it is labeled as gluten-free.

As for PEG 3350, this is a fairly new osmotic laxatives and currently being studied more especially about its safety because it seems the laxative is not fully safe for children and a further studies needed to know more about the effect of this petroleum-derivative compound which is made from ethylene glycol or the same ingredient used in antifreeze.

Miralax and Benefiber Suggestion

To get the best benefit of these fiber solutions, we have to follow the suggestion on their package and with Miralax, we are recommended to take 17 grams of the powder with 4-8 ounce of water and use them once a day no more than 7 days. With Benefiber use 2 teaspoon for 4-8 ounce of water or flavored beverages as long as they are not carbonated and we have to take them 3 times a day but not exceeding 6 teaspoons within 24 hours.

Miralax vs Benefiber

- Laxative - Fiber supplement
- For constipation - For proper daily fiber intake
- PEG 3350 - Wheat dextrin - Wheat dextrin
- No gluten - Still have a little gluten
- Not for prolonged use- Suitable for prolonged use

These supplements are a good solution to help when you are having an irregular bowel movement or constipated but they are also different because Miralax is laxative and designed to not be taken in prolonged time or not for everyday use; only when you are experiencing constipation while Benefiber is more of a daily fiber supplement to fulfill your fiber intake recommendation both to prevent and to handle irregularities. In addition PEG 3350 is laxative and not a fiber like wheat dextrin.

Wheat dextrin is called prebiotic because it is fermented in the large intestine and produce short-chain fatty acids that are great for promoting beneficial bacteria and absorption of minerals but also increase the chance of bloating.


All in all we can choose which fiber or solution depending on the needs but since these two are different, those who are experiencing constipation may want to go with laxative like Miralax while those who want to get a proper fiber as well as prevent the irregularities should take Benefiber.
