When it comes to maintaining digestive health and regularity, fiber supplements can play a crucial role in your daily diet. Two popular choices on the market — Miralax and Benefiber — are for those who seek to increase their fiber intake.
Although both help manage bowel movements, they differ significantly in composition, mechanism of action, and usage recommendations.
In our comparison, we’ll look at how Miralax, a laxative, and Benefiber, a fiber supplement, help with different digestive issues. We’ll check what’s in them, any side effects, and when to use each to help you choose what’s best for your health.
Miralax is a laxative that helps with constipation by making stool softer and increasing bowel movements. It’s used for short-term constipation relief.
Benefiber, in contrast, has wheat dextrin, a natural fiber that supports digestion and regularity. Unlike Miralax, Benefiber is a daily fiber supplement, not a laxative. It moves through the digestive system without breaking down, adding bulk to stool.
Although both are fiber supplements, they act differently. Let’s dive into their ingredients to understand how Miralax and Benefiber work.
What is Miralax?
Miralax is generically known as polyethylene glycol 3350, is an osmotic laxative. This is often recommended by healthcare professionals for the treatment of occasional constipation.
Unlike stimulant laxatives, Miralax works by holding water in the stool to soften it and making it easier to pass without causing a sudden urgency.
This process usually takes one to three days to be effective. The active ingredient, polyethylene glycol, is not absorbed into the body and therefore is considered safe for over-the-counter use when taken as directed. It is important to note that Miralax is meant for short-term use and not as a long-term solution to digestive health.
Ingredients of Miralax
The main ingredient in Miralax is polyethylene glycol 3350 (PEG 3350). It’s a synthetic compound that works as an osmotic agent. It has the unique property of being able to retain water, which in turn softens stool and enhances bowel movements.
PEG 3350 doesn’t get broken down or taken in by the body, so it’s a safe choice for dealing with constipation. It’s safe for adults and kids over six for occasional use, but make sure to follow the package directions or those from a healthcare provider.
Miralax uses and benefits
Here are the key benefits of using Miralax:
- Mainly used to relieve occasional bouts of constipation, Miralax can help restore regular bowel movements.
- It is often regarded as a gentle option, as it does not cause harsh urgency or cramping commonly associated with stimulant laxatives.
- Polyethylene glycol 3350, the active component of Miralax, does not absorb into the bloodstream which makes it safe for most people when used as directed.
- Miralax powder can be mixed with any hot or cold beverage, which makes it easy to ingest.
- It is available over-the-counter and does not require a prescription, which makes it easily accessible.
- Approved for children with a doctor’s recommendation, giving an option for pediatric patients suffering from constipation.
Miralax side effects
While Miralax is generally safe when used as directed, some users may experience side effects. These include:
- Bloating
- Gas
- Cramps
- Nausea
- Increased thirst
- Diarrhea
- Dizziness
If you experience any of these side effects, it is essential to stop using Miralax and consult your healthcare provider.
What is Benefiber?
Benefiber is a natural fiber supplement made from wheat dextrin. It dissolves in water, adds bulk to your diet, and helps keep your bowels healthy and regular. It also supports the growth of good gut bacteria for a balanced gut flora.
Since Benefiber is gluten-free, it can be utilized by those with gluten intolerance or celiac disease. It is tasteless, non-thickening, and can be easily incorporated into your diet without affecting the flavor or consistency of your food and beverages.
Benefiber has a bit of wheat in it, but the makers say it’s gluten-free since it has very little gluten (less than 20 ppm). Still, they warn that if you have trouble with gluten or have celiac disease, it’s best not to use Benefiber unless a healthcare pro says it’s okay.
Ingredients of Benefiber
The primary ingredient, wheat dextrin, is a natural kind of fiber from wheat starch. It melts in liquids, doesn’t make things thick, and tastes like nothing. This type of fiber soaks up water in your gut, making a gel that helps you feel full and pushes waste through your tummy.
Benefiber Uses and Benefits
Here are several benefits and uses of Benefiber:
- Benefiber as a daily supplement can assist in reaching the recommended daily fiber intake, particularly for those struggling with dietary fiber.
- Benefiber is safe for individuals with gluten issues as it is gluten-free and meets FDA regulations for gluten-free products.
- The main ingredient in Benefiber, wheat dextrin, promotes good digestive health by fostering the growth of beneficial gut bacteria.
- Benefiber, a non-thickening powder, can be easily added to beverages and soft foods without changing their texture or taste.
- Regular use of Benefiber can help ease occasional constipation by aiding food movement in the digestive system.
- By enhancing a fiber-rich diet, Benefiber can aid in weight management and stabilizing blood sugar levels.
Benefiber Side Effects
Benefiber is usually fine, but if you’re new to high-fiber foods, you might have some minor side effects while your body gets used to it.
- Bloating
- Gas
- Temporary changes in bowel habits
- Abdominal discomfort
It is key to drink plenty of water when you increase your fiber intake and to increase fiber slowly to minimize potential side effects.

Both Miralax and Benefiber are designed to be taken orally but differ in their dosages and directions due to their varying mechanisms of action:
Miralax Dosage and Directions
- Adults and children 17 years of age and older: The typical dose is 17 grams (about 1 heaping tablespoon) of powder per day. It should be mixed into 4–8 ounces of a beverage (like water, coffee, tea, or juice) and taken once a day.

FAQ
Is Miralax considered a fiber supplement?
No, Miralax is not considered a fiber supplement. It is classified as an osmotic laxative, which works by drawing water into the colon. It softens stools and enhances bowel movements. Unlike fiber supplements that increase the bulk of stool by adding fiber to the diet, Miralax operates by a different mechanism to relieve constipation.
Can I take both Miralax and Benefiber together?
Yes, it is possible to take both Miralax and Benefiber together as they work differently in the body and do not share any known adverse interactions. However, it’s important to start with small doses to see how your body reacts and to consult with a healthcare provider to ensure that this combination is appropriate for your individual health needs.
Do I need a prescription for Miralax or Benefiber?
No, both Miralax and Benefiber are available over the counter, meaning you do not need a prescription to purchase them.
Can I use Miralax or Benefiber to help with weight loss?
Miralax and Benefiber are designed to improve digestive health rather than for weight loss, but some people use fiber supplements like Benefiber as part of their weight management plan due to fiber’s ability to promote feelings of fullness. However, Miralax does not contribute to weight loss as it works by drawing water into the colon to increase stool movement rather than affecting appetite or digestion.
Are there any special considerations for using Miralax or Benefiber with other medications or health conditions?
Yes, there are specific considerations when using these with other medications. Due to their fiber content, products like Benefiber may change the absorption of some medications, so it is advisable to take other medications either 1 hour before or 2 hours after taking fiber supplements. For Miralax, while it usually has fewer interactions with medications, it’s important for people with kidney disease or on certain medications to consult their healthcare provider due to its sodium content and the way it works in the body.
