IMPORTANT UPDATE (October 2025): Citrucel Powder with Sugar Has Been Discontinued.
While the comparison of active ingredients in this article remains accurate, please be aware that Haleon no longer produces the original Citrucel with Sugar. For the full story and to learn about its direct generic replacement, please read our detailed announcement.
If you’re comparing Citrucel vs Metamucil to support regularity, the big difference comes down to fiber type: methylcellulose (Citrucel and its generic) vs psyllium husk (Metamucil). This guide breaks down benefits, side effects (gas/bloating), taste and mixability, costs, and who each works best for—including links to taste tips and mixing without clumps, plus our in-depth overview of Citrucel generic alternatives.
Why Fiber Supplements Matter
Dietary fiber helps regulate bowel movements, ease occasional constipation, support weight management, and contribute to heart health. If you don’t consistently hit your daily fiber targets from food, a supplement such as Metamucil or Citrucel can help fill the gap—without overhauling your entire diet.
Citrucel vs Metamucil: Quick Comparison
| Feature | Citrucel | Metamucil |
|---|---|---|
| Fiber Type | Methylcellulose (soluble, non-fermentable) | Psyllium husk (soluble + insoluble) |
| Fermentable? | No – typically less gas | Yes – may cause gas or bloating |
| Bloating Risk | Low | Moderate to high (varies by tolerance) |
| Digestive Sensitivity | Often preferred for IBS or sensitive stomachs | Effective, but can trigger bloating in some |
| Sugar-Free Options | Available | Available |
| How It Works | Forms a gel to ease stool passage | Adds bulk and retains water in stool |
| Best For | Gas sensitivity, gentler daily regularity | Extra bulk for constipation relief |
| Generic Alternative | Major Fiber Therapy | GoodSense Psyllium Fiber Powder |
Citrucel: The Gentle Fiber Supplement
Composition: Citrucel contains methylcellulose, a non-fermentable soluble fiber.
Effect: It absorbs water and forms a gel-like substance to promote regular bowel movements. Because its non-fermentable, many users report fewer issues with gas and bloating—one reason Citrucel generic alternatives remain popular for sensitive digestion.
Key Benefits of Citrucel:
- Gentler option if you’re prone to gas or bloating
- Often preferred for IBS or sensitive stomachs
- Available in flavored and sugar-free varieties

Metamucil: The Psyllium Fiber Powerhouse
Composition: Metamucil’s active ingredient is psyllium husk, a natural fiber derived from the Plantago ovata plant.
Effect: Psyllium swells and forms a gel when mixed with liquid, softening stool and supporting regularity. It’s well-known for constipation relief and can also support heart health as part of a healthy diet.
Key Benefits of Metamucil:
- Highly effective for constipation relief
- May help lower cholesterol
- Can promote fullness, which may aid weight management
Key Differences: Citrucel vs Metamucil
Both support digestive health, but there are important differences:
- Fiber source: Methylcellulose (Citrucel) vs psyllium husk (Metamucil)
- Gas/bloating: Non-fermentable methylcellulose typically causes less gas
- Calories/carbs: Many methylcellulose options are lower in calories than sweetened psyllium blends
- Formulations: Products may include sweeteners or flavors—check labels if you’re limiting sugar
- Cost: Psyllium name brands can be pricier; methylcellulose generics often save money
- Taste/mixability: Methylcellulose is often reported to dissolve more smoothly in water

Citrucel vs Metamucil: Which One Is Better?
It depends on your goals and tolerance:
Citrucel might be your preferred choice if you:
- Have a sensitive stomach or IBS
- Are prone to gas or bloating
- Prefer a smoother, easier-to-mix texture
Metamucil could be a better fit if you:
- Want extra stool bulk for constipation relief
- Are targeting cholesterol support alongside regularity
- Prefer a plant-based (psyllium) fiber source

Citrucel vs Metamucil: Which Is Better for Irritable Bowel Syndrome (IBS)?
Choosing between methylcellulose and psyllium for IBS depends on your symptoms and tolerance:
Citrucel (Methylcellulose)
- Type: Non-fermentable; typically less gas
- How it works: Forms a gel, softens stool, eases passage
- Best for: Users bothered by bloating and gas
- Common use: Constipation-predominant IBS (IBS-C)
Metamucil (Psyllium Husk)
- Type: Fermentable; may cause gas initially
- How it works: Adds bulk and retains water in stool
- Best for: IBS-M or IBS-D where bulking helps consistency
- Common use: Overall digestive regularity
Which Is Better for IBS?
- IBS-C: Both may help; methylcellulose often preferred if gas is a concern
- IBS-D: Psyllium may help bulk stool (start low to reduce side effects)
- IBS-M: Psyllium is frequently recommended for balancing swings
Personal Tolerance Matters
Each gut is different. Try one at a time with plenty of water and adjust dose gradually. Talk with your healthcare provider before starting a new fiber supplement, especially if you have IBS or other GI conditions.
Citrucel vs Metamucil: Which Is Right for You?
The choice between Citrucel and Metamucil ultimately depends on your sensitivity to gas, your need for stool bulk, and your broader health goals. Many with gas/bloating prefer methylcellulose; those prioritizing extra bulk or heart-health benefits may lean toward psyllium. When in doubt, consult a clinician or pharmacist for personalized guidance.
