What is the difference between Metamucil with sugar and sugar free?

Metamucil is a popular fiber supplement that can be taken to help promote regularity and relieve occasional constipation. It contains psyllium husk, which is a natural source of fiber. Metamucil comes in different varieties, including options with sugar and sugar-free versions. Understanding the differences between Metamucil with sugar and sugar-free can help you choose the best option for your needs.

What is Metamucil?

Metamucil is a fiber supplement made from psyllium husk. Psyllium comes from the Plantago ovata plant. It is a natural soluble fiber that can absorb water and form a gel-like substance in the digestive tract. This helps add bulk and moisture to stools, allowing them to pass more easily.

Metamucil contains psyllium husk as its main active ingredient. It comes as a powder that can be mixed with water or juice and drank. Metamucil is commonly used for:

– Relieving occasional constipation
– Promoting regularity
– Supporting heart health
– Aiding weight management
– Lowering cholesterol

The psyllium husk in Metamucil can help increase stool size and improve the frequency of bowel movements. This makes it useful for addressing constipation and irregularity.

Metamucil with Sugar

One popular formulation of Metamucil contains psyllium husk along with sugar. The sugar is added to the psyllium to give Metamucil a sweet taste and improve its palatability.

Metamucil with sugar contains approximately 15 grams of sugar per serving. The sugar is often sucrose or dextrose. These simple sugars dissolve easily in liquids.

Adding sugar makes Metamucil more pleasant to drink. The powder has a bland, grainy texture on its own. The sugar masks the natural flavor of the psyllium husk.

Many people prefer Metamucil with sugar as it is easier to drink regularly. The sugar makes the drink taste sweeter and less grainy or chalky.

Benefits of Metamucil with Sugar

– More palatable taste
– Easier to drink for long-term use
– Provides easy calories
– Kids may prefer the sweeter taste

Downsides of Metamucil with Sugar

– Contains empty calories from added sugar
– Not suitable for low-sugar diets
– Increases blood sugar levels
– Can lead to weight gain if consumed in excess
– Not appropriate for people with diabetes

Sugar-Free Metamucil

Sugar-free Metamucil provides the same fiber content from psyllium husk but does not contain added sugar. It uses alternative natural sweeteners to enhance the flavor.

Common sweeteners in sugar-free Metamucil include:

– Sucralose – An artificial sweetener also known as Splenda
– Acesulfame potassium – An artificial sweetener
– Stevia – A natural low-calorie sweetener
– Aspartame – An artificial sweetener known as Equal

These non-nutritive sweeteners provide a sweet taste but without the extra calories of sugar. They allow people to get the benefits of Metamucil without added sugars.

Benefits of Sugar-Free Metamucil

– No extra calories
– Does not impact blood sugar levels
– Suitable for diabetes management
– Appropriate for low-carb and keto diets
– Helps avoid weight gain from added sugars

Downsides of Sugar-Free Metamucil

– Some people dislike the taste of artificial sweeteners
– Debatable health impact of non-nutritive sweeteners
– May not dissolve or mix as well in liquids

Nutritional Profile

The main difference in the nutritional profile of regular versus sugar-free Metamucil is the sugar content:

Metamucil with Sugar Nutrition Facts

Amount per serving:

– Calories: 70
– Total Fat: 0g
– Sodium: 160mg
– Potassium: 25mg
– Total Carbs: 15g
– Sugars: 15g
– Protein: <1g

Sugar-Free Metamucil Nutrition Facts

Amount per serving:

– Calories: 30
– Total Fat: 0g
– Sodium: 190mg
– Potassium: 22mg
– Total Carbs: 7g
– Sugars: 0g
– Protein: <1g

As you can see, the regular Metamucil contains 15 grams of sugar and 70 calories per serving. The sugar-free version has no sugar and only 30 calories.

The fiber content from the psyllium husk is the same between both products. So you get the same 5 grams of dietary fiber, with or without the added sugar.

Taste Comparison

In terms of taste, there is a noticeable difference between Metamucil with sugar and the sugar-free formulation:

– Metamucil with sugar has a sweeter, more pleasant taste. The sugar makes it easier to drink and masks the natural grainy texture.

– Sugar-free Metamucil does not dissolve as well in water. It has a duller, more artificial taste depending on the specific sweetener used. Some people notice a bitter or chemical-like aftertaste.

– The sugar-free version may seem grittier or grainier when drinking it. Without sugar, the psyllium husk does not fully dissolve.

– Some sugar-free versions use higher-quality sweeteners like stevia that have a more natural taste. These can come closer to regular Metamucil.

So in general, Metamucil with sugar tends to taste better, while the sugar-free kind has a more artificial, gritty texture. However, taste preferences are individual.


Related to taste, there is a difference in how well the two varieties of Metamucil mix in water or other liquids:

– Regular Metamucil with sugar mixes smoothly and blends more seamlessly with water, juice, or smoothies.

– Sugar-free Metamucil is more prone to clumping. The psyllium husk does not dissolve as well without the sugar to help break it down.

– Mixing sugar-free Metamucil requires vigorous stirring, shaking, or blending to break up clumps. It does not achieve the same smooth consistency.

– Allowing sugar-free Metamucil to sit and thicken for a few minutes after mixing can improve its texture.

– Using a blender rather than just stirring helps sugar-free Metamucil dissolve and incorporate more smoothly.

So the versions with added sugar tend to mix better than the sugar-free alternatives. But with sufficient stirring or blending, both can be dissolved in water or other liquids.

Gas and Bloating

Some people experience gas or bloating when using Metamucil or other psyllium supplements. This occurs as the psyllium moves through the colon and ferments.

There are a few differences between the two formulations:

– Metamucil with sugar may produce slightly more gas since sugar is also fermented by gut bacteria.

– The artificial sweeteners in sugar-free Metamucil are not broken down in the digestive tract, so they do not produce gas.

– Starting with a lower dose and increasing slowly can help minimize gas with either type of Metamucil.

– Drinking plenty of fluids and moving around helps move gas out to reduce bloating.

– Probiotics can help balance gut bacteria and ease digestive side effects.

Overall, both versions can cause some intestinal gas, but the higher sugar content of regular Metamucil may exacerbate this effect for some people.

Cost Comparison

On average, regular Metamucil costs slightly more than the sugar-free versions:

– Metamucil Original Sugar: $0.20 per serving

– Metamucil Sugar-Free: $0.15 per serving

However, prices can vary between stores, geographic regions, package sizes, and sales promotions. Generic and store brand versions with sugar may be priced lower than the name brand.

Sugar-free Metamucil requires more specialized sweeteners, so this may contribute to the somewhat higher price. But overall there is not a major cost difference between the two.

Weight Management

Fiber supplements like Metamucil can be useful for weight management plans. Both types provide fiber to promote satiety and healthy digestion.

However, there are some notable differences:

– Metamucil with sugar contains more calories – about 70 calories per serving versus 30 calories for the sugar-free kind.

– The extra 15g of sugar adds empty calories and carbohydrates.

– Sugar-free Metamucil may be preferable for low-carb, keto, or other low-sugar diets.

– The sugar alcohol sweeteners in sugar-free Metamucil have fewer calories than sucrose.

– Blood sugar spikes from high sugar intake can increase hunger and lead to overeating.

So for weight loss purposes, sugar-free Metamucil may be the better choice. But both can be incorporated into an overall healthy diet.

Diabetes Considerations

Metamucil contains soluble fiber that can help regulate blood sugar levels. However, there are important considerations for people with diabetes:

– Sugar-free Metamucil is the better option as it will not spike blood glucose.

– Regular Metamucil with sugar will raise blood sugar as the sugars are absorbed.

– Fiber slows digestion of carbohydrates, helping control blood sugar changes.

– Metamucil taken with meals may require medication dosage adjustments for diabetes.

– Sugar alcohols like sorbitol can still impact blood glucose but less than regular sugars.

Consulting a doctor is important when using Metamucil with diabetes to ensure proper medication and diet management. But fiber supplements can provide benefits when used correctly.

Other Health Benefits

Some other potential health benefits are seen from psyllium supplements like Metamucil:

– May lower LDL and total cholesterol levels
– Reduces risk of heart disease and high blood pressure
– Lowers triglycerides
– Improves regularity which reduces toxin buildup
– Provides rich source of soluble fiber lacking in many diets
– Adds bulk to stools to reduce pressure and constipation

The high soluble fiber content of psyllium is responsible for many of these benefits as fiber has wide-reaching effects on digestion and metabolism.

Who Should Choose Sugar-Free Metamucil?

The sugar-free version may be preferable for people who:

– Have diabetes or blood sugar regulation issues
– Are monitoring their calorie or carb intake
– Follow a low-sugar, keto, or paleo diet
– Are sensitive to sugar or experience energy crashes
– Want to limit empty calorie foods
– Need to avoid gas, bloating, and digestion issues

For most other people, the regular Metamucil with sugar is fine to use and provides an easier drinking experience. But sugar-free is ideal for anyone watching their sugar intake for health reasons.


Metamucil with sugar and sugar-free both provide the same soluble fiber from psyllium husk. This fiber helps normalize bowel movements and offers other digestive and heart health benefits.

The main difference is the addition of sugar to the regular Metamucil to improve its taste, texture, and mixability. However, the sugar adds extra calories and carbs that may be undesirable for some.

Sugar-free Metamucil uses non-nutritive sweeteners instead to remove the extra sugar. However, some people find the taste less natural. Sugar-free Metamucil also does not dissolve quite as smoothly.

In general, Metamucil with sugar is easier to drink for long-term use. But sugar-free is better for diets like keto and any health conditions where sugar intake should be restricted. Both provide the helpful fiber, and personal taste preference plays a large role in choosing between the two.
