What is Citrucel and its Active Ingredient?
Citrucel is a brand-name, over-the-counter medication widely used to treat occasional constipation and maintain regularity. The key to understanding its function lies in its active ingredient: methylcellulose. Methylcellulose is a soluble, non-fermentable fiber derived from plant-based cellulose. Unlike other fiber types that are fermented by bacteria in the gut, methylcellulose passes through the digestive system largely intact. This non-fermentable characteristic is why Citrucel is often promoted as a fiber supplement that helps with constipation without causing the excess gas and bloating sometimes associated with other fiber sources. By absorbing water, methylcellulose adds bulk and softness to the stool, making it easier to pass.
How Citrucel Functions as a Fiber Supplement
As a bulk-forming laxative, Citrucel's methylcellulose works similarly to dietary fiber found in whole foods. When mixed with a sufficient amount of liquid, the powder or caplets form a gel-like substance in the gut. This gel adds mass to the stool, and by retaining water, it softens it. The increased bulk stimulates the bowels to contract and push the stool through the digestive tract, resulting in a more comfortable and frequent bowel movement. This process typically takes between 12 and 72 hours to produce an effect. The advantage of using a non-fermentable fiber like methylcellulose is that it can provide these effects without the typical side effects of gas and bloating that can occur with fermentable fibers.
Citrucel vs. Metamucil: A Fiber Comparison
To highlight how Citrucel works, it is useful to compare it to one of its most popular competitors, Metamucil. While both are fiber supplements and bulk-forming laxatives, their active ingredients are different, which leads to different digestive effects.
| Feature | Citrucel (Methylcellulose) | Metamucil (Psyllium Husk) |
|---|---|---|
| Active Ingredient | Methylcellulose | Psyllium Husk |
| Fiber Type | 100% Soluble, Non-fermentable | Primarily Soluble, Highly Fermentable |
| Mechanism | Adds bulk and holds water, remains intact in gut | Forms a gel, absorbs water, and is fermented by gut bacteria |
| Side Effect Risk | Less likely to cause gas and bloating | More likely to cause gas and bloating |
| Additional Benefits | Primarily focused on regularity | Better at lowering cholesterol and regulating blood sugar |
| Texture | Less gritty, smoother texture | Often described as having a thicker, grittier texture |
For those with sensitive digestive systems or concerns about excess gas, Citrucel's methylcellulose fiber offers a gentler alternative. However, Metamucil's psyllium has been shown to be more effective at lowering cholesterol levels due to its gel-forming properties. The best choice depends on individual health goals and tolerance.
How to Use Citrucel Safely and Effectively
When taking Citrucel or any bulk-forming fiber supplement, proper usage is essential for safety and effectiveness. The most important instruction is to mix the supplement with a full glass of water (at least 8 ounces) and drink it promptly. This prevents the powder from swelling in the throat and causing a choking hazard. Drinking an additional glass of water is also recommended to ensure proper hydration and help the fiber move through the system effectively. It is best to start with a lower dose and gradually increase it to avoid potential side effects like temporary abdominal discomfort. Most products are for short-term use, and if constipation persists for more than seven days, a doctor should be consulted. Fiber supplements like Citrucel should not be used as a replacement for a healthy, balanced diet rich in natural fiber from fruits, vegetables, and whole grains.
Conclusion
In summary, Citrucel is definitively considered a fiber supplement, specifically a bulk-forming laxative containing methylcellulose fiber. Its defining feature is that it is a non-fermentable soluble fiber, which makes it less likely to cause gas and bloating compared to fermentable fiber supplements like Metamucil. This characteristic makes Citrucel a suitable option for individuals with sensitive digestive systems who need to relieve occasional constipation and improve regularity. However, for additional benefits like cholesterol reduction, psyllium-based products might be more effective. As with any medication, it is important to follow all directions and consult a healthcare professional if symptoms persist beyond a week.
