Citrucel Review

Editor's Rating:

This is a review of Citrucel with SmartFiber.  This soluble fiber supplement is made with methylcellulose that promotes regularity, relieving both constipation and diarrhea. The manufacturer claims that the SmartFiber formula will not ferment in the gut, causing uncomfortable side effects such as bloating and gas. Continue reading to see if this product will benefit you.


This product contains:

  • Methylcellulose 500 mg per caplet

The active ingredient, methylcellulose, is a non-allergic fiber. Made with cellulose, it is completely water soluble and works by adding bulk to the stool, resulting in firmer bowel movements for diarrhea sufferers and having a softening effect on the stool which eases constipation. Inactive ingredients include: Crospovidone, Dibasic Calcium Phosphate, FD&C Yellow No. 6 Aluminum Lake, Magnesium Stearate, Maltodextrin, Povidone, Sodium Lauryl Sulfate and 10 mg of Calcium per capsule.

Citrucel is also available in powered form, with both regular and sugar free options. The manufacturer does not state whether either form is vegetarian friendly. The sugar free form of Citrucel with SmartFiber contains aspartame. Aspartame is an artificial sweetener that may not be well tolerated by some IBS sufferers.


Adults and children over 12 years old are advised to take 2 caplets up to 6 times daily. Children aged 6-12 years, 1 caplet up to 6 times per day. For children younger than 6 years old, speak with a doctor for dosage instructions.

The supplement can be taken with or without food, but it must be taken with a minimum of 8 ounces (240ml) of water. Failing to do so may cause a choking hazard. It should be taken 2 or more hours before or after medications.

Possible Side Effects

The most common side effect associated with this product is a feeling of fullness. It is safe to use long-term. Seek medical attention right away if you experience an allergic reaction to any of the ingredients.


Citrucel with SmartFiber is available at a variety of retailers and online at Amazon. Prices start at $19.52 for 220 caplets, and $9.98 for a 16 ounce container of the powdered form of the product.


The manufacturer does not offer a money back guarantee, leaving the customer subject to the terms and conditions of the retailer they have purchased from. There are a limited number of customer reviews online and none on the product website itself, but the reviews we did find are primarily positive in nature.


Citrucel with SmartFiber is a reasonably priced product which contains a standard dose of soluble fiber. The SmartFiber comes from cellulose, which will not ferment in the stomach, thus avoiding the bloating and gas that some supplements of this kind are known for. It is available in both caplet and powder form for convenience. However, the sugar free version of the powder form uses aspartame as a sweetener. There is also no mention of whether the products are vegetarian friendly. With no specific quality guarantee from the manufacturer, new customers may hesitate to purchase this supplement.
