Metamucil Alternatives, Compared Gram for Gram (Including Ones Without Aspartame)
Share
Last updated October 7, 2026 · By the Fiber Society team
A Metamucil alternative comes in five forms: another psyllium product (plain psyllium husk powder, or Metamucil's own stevia-sweetened Premium Blend if aspartame is the issue), a wheat dextrin powder such as Benefiber, a methylcellulose powder such as Citrucel, fiber gummies, or a multi-fiber blend such as Fiber Society's Daily Fiber Blend. What separates them: grams of fiber per serving, which fiber it is (gel-forming psyllium, non-viscous wheat dextrin, or viscous-but-not-gel-forming methylcellulose), and the sweetener and dyes in the scoop. Here is the comparison, per each label as of October 2026.
Key takeaways
- Per the label as of October 2026, Metamucil 4-in-1 Fiber Sugar-Free Orange is sweetened with aspartame and colored with Yellow 6; Metamucil Premium Blend uses stevia, paprika extract, and turmeric.
- Grams per serving vary widely: Citrucel Sugar Free Orange gives 2 g of methylcellulose per rounded tablespoon, Metamucil powders 3 g per rounded teaspoon, Benefiber Original 6 g per 4 teaspoons, Fiber Society Daily Fiber Blend 10 g per scoop.
- Psyllium forms a gel and is not fermented; wheat dextrin does not thicken and is readily fermented; methylcellulose is viscous but not gel-forming and is not fermented (McRorie, 2015).
- The FDA Daily Value for dietary fiber is 28 g, so 3 g is 11% DV, 6 g is 21% DV, and 10 g is 36% DV.

Why people look for Metamucil alternatives
The sweetener. Per the label as of October 2026, Metamucil 4-in-1 Fiber Sugar-Free Orange lists aspartame and states "Contains phenylalanine 25 mg per teaspoon." The FDA says aspartame is an approved sweetener whose safety for the general population is supported by the evidence under approved conditions of use, and it requires that statement for people with phenylketonuria (PKU). Choosing not to use aspartame is a preference, not a safety verdict.
The color and the grams. The same label lists Yellow 6, a synthetic dye; Premium Blend lists paprika extract and turmeric instead. And one rounded teaspoon of Metamucil powder provides 3 g of fiber, so 10 g takes more than three teaspoons; hence the "servings to reach 10 g" column.

Metamucil without aspartame: your options
If aspartame is the only thing you want to change, you can stay with psyllium. Per the labels as of October 2026:
- Metamucil Premium Blend, Sugar-Free Orange with Stevia. Same psyllium base, 3 g per rounded teaspoon, with stevia, paprika extract, turmeric, maltodextrin, and natural orange flavor.
- Metamucil 4-in-1 Fiber Powder, Unflavored. Its DSLD label lists two ingredients, sugar and psyllium. No aspartame, but it contains added sugar.
- Plain psyllium husk powder. Single-ingredient labels (Viva Naturals lists psyllium husk powder and nothing else) have no sweetener, flavor, or color.
- A different fiber. Benefiber Original is unsweetened wheat dextrin with 0 g total sugars. Fiber Society Daily Fiber Blend is sweetened with stevia (Reb M), with no aspartame or sucralose.
Psyllium vs wheat dextrin vs methylcellulose: what each fiber does
A two-part 2015 review in Nutrition Today by Johnson McRorie sorted supplement fibers by whether they hold water (viscosity, gel formation) and whether gut bacteria ferment them. In that scheme, acacia (gum arabic), the main fiber in Fiber Society's blend, is low-viscosity and fermented; inulin, in Metamucil's gummies, is non-viscous and readily fermented. See acacia vs psyllium and psyllium vs inulin.
Psyllium: gel-forming and not fermented
McRorie classifies psyllium as "soluble viscous/gel forming, nonfermented." Because bacteria do not break it down, it "retains its water-holding gelled structure throughout the large bowel." That gel is why psyllium drinks thicken if they sit and why labels say drink promptly.
Wheat dextrin (Benefiber): non-viscous and readily fermented
Wheat dextrin is "soluble, nonviscous, readily fermented." It dissolves clear, as the Benefiber label says, but McRorie notes it "does not gel or alter viscosity and thus does not provide any of the gel-dependent fiber health benefits," and once fermented it has "no water-holding capacity."
Methylcellulose (Citrucel): viscous, not gel-forming, not fermented
Methylcellulose is a semisynthetic fiber from chemically treated wood pulp. McRorie's table places it in the "soluble viscous" column, with water-holding capacity but no gel formation, and lists it as "nonfermented." Citrucel's Drug Facts label calls it "a non-allergenic fiber."
Benefiber vs Metamucil: the short version
- Fiber: Metamucil is psyllium husk (gel-forming, not fermented). Benefiber Original is wheat dextrin (non-viscous, readily fermented).
- Grams: Metamucil powders give 3 g per rounded teaspoon. Benefiber Original gives 6 g per 4-teaspoon (8 g) serving, per the Haleon label dated April 2025.
- Everything else: Metamucil Sugar-Free Orange lists aspartame and Yellow 6 (15 calories per teaspoon). Benefiber Original lists one ingredient, wheat dextrin (30 calories per serving), and its label says clear, taste-free, dissolves completely.
How to read a fiber supplement label
- Serving size. Often a range ("1 to 2 rounded teaspoons"); every number on the panel refers to that serving.
- Dietary fiber, in grams. The number to compare; "soluble fiber" sub-lines are optional and inconsistently reported.
- % Daily Value. The FDA Daily Value for dietary fiber is 28 g per day for adults and children age 4 and older; 5% DV or less per serving is low, 20% DV or more is high.
- The ingredient line. Fiber source first, then maltodextrin, flavor, sweetener (aspartame, sucralose, stevia, xylitol, or sugar), and colors. Yellow 6 is a synthetic dye; annatto, paprika extract, and turmeric are plant-derived.
Then divide 10 by the grams per serving to see how many servings reach 10 g, roughly a third of the Daily Value. For the full 28 g on a plate, see what 25 grams of fiber looks like.
FAQ
Is there a Metamucil without aspartame?
Yes. Per the label as of October 2026, Metamucil Premium Blend Sugar-Free Orange is sweetened with stevia, and Metamucil 4-in-1 Fiber Powder Unflavored lists only sugar and psyllium. The 4-in-1 Sugar-Free Orange powder is the version that lists aspartame.
What is the difference between Benefiber and Metamucil?
The fiber. Benefiber Original is wheat dextrin (dissolves clear, readily fermented), 6 g per 4 teaspoons. Metamucil is psyllium husk (forms a gel, not fermented), 3 g per rounded teaspoon.
Is Citrucel the same as Metamucil?
No. Citrucel's active ingredient is methylcellulose, 2 g per rounded tablespoon, sold as an over-the-counter drug with a Drug Facts panel; Metamucil is psyllium husk sold as a dietary supplement. Both the Sugar Free Orange versions list aspartame and Yellow 6.
Do fiber gummies have as much fiber as powder?
Usually less per serving. Metamucil Fiber Gummies provide 5 g per 3 gummies from inulin and soluble corn fiber, with 2 g total sugars and 0 g added sugars. See fiber gummies vs powder.
Where Fiber Society fits
Fiber Society makes one of the products in the table, so read this section with that in mind. Daily Fiber Blend (Strawberry Lemonade) is a multi-fiber powder: each 14.2 g scoop provides 10 g of dietary fiber (36% DV) from organic acacia (7.3 g), psyllium husk (2.5 g), Fibersol-2 resistant maltodextrin (1.95 g), and BeniCaros carrot fiber (300 mg), with about 20 calories and 0 g sugar. It is sweetened with stevia (Reb M), has no aspartame, sucralose, or synthetic dyes, and is vegan and gluten-free. Because most of the fiber is acacia and psyllium is kept to 2.5 g, it is designed to drink thin in 350 to 400 ml of cold water. It is high in fiber: 10 g per glass, 0 g sugar, about 20 calories. A pouch holds 28 servings: 20% off on a 4-week subscription, or one-time at the regular price.
It is gentle by design: start with half a scoop for the first few days, do not exceed 2 scoops a day, take it at least 2 hours apart from oral medications, and always use at least a full glass of liquid. Too little liquid can cause choking; do not take it if you have difficulty swallowing.
