Can celiacs use Metamucil?

Celiac disease is an autoimmune disorder that causes damage to the small intestine when gluten is ingested. Gluten is a protein found in wheat, barley, and rye. When someone with celiac disease eats gluten, their immune system mistakenly attacks the small intestine, causing inflammation and damage to the villi – the small, finger-like projections that line the small intestine and absorb nutrients from food.

This damage to the villi results in an inability to properly absorb nutrients from food. Common symptoms of celiac disease include diarrhea, abdominal pain, bloating, fatigue, weight loss, and malnutrition. The only treatment for celiac disease is adhering to a strict gluten-free diet, avoiding all foods and products containing wheat, barley, rye, and sometimes oats.

What is Metamucil?

Metamucil is a fiber supplement made by Procter & Gamble. It contains psyllium husk as its main active ingredient. Psyllium is a type of soluble fiber derived from the Plantago ovata plant. When mixed with water, psyllium husk becomes gelatinous and thick. This allows it to pass through the digestive tract relatively intact, providing bulking and texture.

Metamucil is used to help promote regularity and relieve occasional constipation. The psyllium husk attracts water as it passes through the intestines, softening the stool and allowing for easier passage. Metamucil comes in powder, capsule, wafer, and gummy forms. The powder is generally mixed into water or another liquid and drank.

Is Metamucil Gluten-Free?

Metamucil’s main ingredient, psyllium husk, is naturally gluten-free. Psyllium is derived from the Plantago ovata plant, not wheat or grains that contain gluten. Pure psyllium fiber itself does not contain any gluten.

However, Metamucil products may contain other ingredients besides psyllium that could potentially contain traces of gluten. The brand advises anyone following a gluten-free diet to carefully read the ingredients list and description for each individual Metamucil product.

Metamucil Powders

Metamucil powders contain psyllium husk as the main ingredient but are often blended with additional fibers, sweeteners, flavors, and preservatives. Most of Metamucil’s powder products are labeled as gluten-free:

  • Metamucil Premium Blend
  • Metamucil MultiHealth Fiber
  • Metamucil Sugar Free
  • Metamucil Smooth Citrus Flavor
  • Metamucil Smooth Orange Flavor

However, some Metamucil powders do contain gluten or do not have a gluten-free label. These include:

  • Metamucil Appetite Control Formula
  • Metamucil 3-in-1 Fiber Drink Mix with Probiotics (Berry Burst)

Metamucil Capsules & Wafers

Metamucil capsules and wafers contain fewer additional ingredients than the powders. Most formulas and flavors of Metamucil capsules and wafers are labeled gluten-free by the manufacturer:

  • Metamucil MultiHealth Fiber Clear & Natural Capsules
  • Metamucil MultiHealth Fiber Capsules (Berry Burst, Orange Smooth)
  • Metamucil MultiHealth Fiber Wafers (Chocolate, Cinnamon Spice, Lemon Crisp, Orange)

Metamucil Gummies

Metamucil gummies are a relatively new product offering from the brand. Currently, there is just one formula of Metamucil Sugar-Free Gummies available in Wild Berry flavor. These gummies are labeled gluten-free by the manufacturer.

Are Any Metamucil Products Not Gluten-Free?

While most Metamucil products are gluten-free, there are a few exceptions:

  • Metamucil Appetite Control: contains wheat dextrin
  • Metamucil 3-in-1 Berry Burst Powder: contains barley malt extract
  • Discontinued Metamucil products or limited/special edition flavors may also contain gluten

Individuals following a gluten-free diet should be sure to check the ingredient list and product details carefully when purchasing Metamucil. Call the manufacturer if you have any concerns about whether a specific Metamucil item is gluten-free.

Is Metamucil Safe for People with Celiac Disease?

For most people with celiac disease, pure psyllium fiber supplements like Metamucil should be safe in moderation. Here are some things to consider when deciding whether Metamucil is appropriate for someone with celiac disease:


There are several potential benefits of Metamucil for celiacs:

  • Added fiber: Celiac disease can damage the small intestine and impact its ability to absorb nutrients from food. This may result in a deficiency of fiber. Metamucil adds soluble fiber to help balance this out.
  • Relieves constipation: Constipation due to impaired nutrient absorption is common in untreated celiac disease. The extra fiber from Metamucil can help regulate bowel movements.
  • Supports gut health: Some research indicates supplementing with psyllium fiber may help support intestinal health in celiac disease.


However, there are also some cautions to keep in mind:

  • Cross-contamination risk: Even if labeled gluten-free, Metamucil products could potentially contain traces of gluten from cross-contamination during manufacturing. This risk may not be acceptable for more sensitive celiacs.
  • May cause temporary bloating/gas: A sudden increase in Metamucil or fiber intake can sometimes cause digestive side effects as body adjusts.
  • Interactions with medications: Metamucil/psyllium can impact how certain medications are absorbed. Celiacs should consult their doctor before use.

Personal Tolerance

The best way to gauge compatibility with Metamucil is for those with celiac disease to slowly introduce it and see how their individual body responds:

  • Start with a small dose mixed in water 1-2x per day.
  • Gradually increase intake up to recommendation on packaging.
  • Watch for any digestive upset, bloating, nausea or other symptoms.
  • Discontinue use if any bothersome reactions occur.

Drinking plenty of water and maintaining a balanced gluten-free diet can also help support tolerance of Metamucil.

Other Brands of Psyllium Husk Fiber

In addition to Metamucil, there are a number of other psyllium husk fiber supplement brands on the market. These include more “natural” options that contain just psyllium husk without artificial colors, flavors, or sweeteners. Here are some potential gluten-free psyllium supplement alternatives to Metamucil:

Brand Product(s)
Yerba Prima Psyllium Husks Capsules, Psyllium Husks Powder
Heather’s Tummy Fiber Organic Psyllium Husk Capsules

Celiacs should still carefully check the ingredients and manufacturing details of any psyllium husk supplement to ensure it is gluten-free before consuming.

Other Constipation Remedies for Celiacs

In addition to psyllium supplements, there are other natural ways those with celiac disease can help relieve constipation without gluten exposure:

  • Increase hydration: Drink plenty of water and fluids like broths or herbal teas.
  • Consume probiotics: Probiotic foods or supplements may improve gut motility.
  • Exercise regularly: Any physical activity can help stimulate the bowels.
  • Reduce stress: High stress can impact gut function and transit time.
  • Eat more fruit and veggies: Produce provides fiber and important nutrients for digestion.
  • Use magnesium supplements: Magnesium helps relax tight muscles and draw water into the intestines.

Those with persistent issues should see their doctor to address the underlying cause and rule out complications of celiac disease. Ongoing constipation can sometimes indicate continued gluten exposure or refractory disease.

The Bottom Line

Most Metamucil products are gluten-free and well-tolerated by celiacs when consumed in moderation. The key is starting slow and picking psyllium supplements with clean ingredient profiles to minimize any additive reactions.

Pure psyllium fiber offers benefits like added fiber intake and relief from constipation frequently experienced with celiac disease. Just be sure to watch for any individual sensitivities. Combining Metamucil or other psyllium supplements with a balanced gluten-free diet and healthy lifestyle optimizes digestion and gut function for those with celiac disease.
