When to Consult Your Doctor
Everyday Health recommends speaking with your doctor before adding any supplement to your diet to make sure it’s safe and appropriate for your individual health needs. Some supplements can interact with medications, so if you take any prescribed medications, always talk with your doctor first. While fiber supplements are generally well tolerated, sometimes they can lead to temporary gastrointestinal (GI) distress like gas, bloating, cramping, and change in bowel movements. Your doctor can help you understand how the supplement will affect you and whether any symptoms you experience are cause for concern.

- Dissolves quickly, doesn’t change the texture of food or drink
- Unflavored

If you’re looking for a fiber supplement, chances are you’ve experienced some digestive discomfort. Some fiber supplements may not sit well with people with sensitive stomachs, but Tomorrow’s Nutrition SunFiber was designed to be gentle on your digestive system with a low FODMAP-certified formula. FODMAPs are a group of carbohydrates that can lead to digestive issues in some people, especially those with irritable bowel syndrome (IBS).
One of the biggest benefits of this formula is that it doesn’t change the consistency of whatever you mix it into. Some fiber supplements thicken the food or liquid that you add it to, and some may add a gritty texture. SunFiber’s formula dissolves completely, making it easier to swallow and consume regularly.
The formula is also gluten-free, dairy-free, and certified organic. Tomorrow’s Nutrition SunFiber supplements are third-party tested by LGC Assure and have Informed Ingredient Certification that confirms the supplements are free of impurities and substances banned in sports nutrition products.

Best for Weight Loss

Pros
- Helps manage hunger and feeling of fullness
- Gluten-free, paleo, keto-friendly

It’s worth noting that it thickens whatever liquid you mix it into, so it may not be best with plain liquids where the consistency could be unpleasant or even unsafe for people who have trouble swallowing. On the other hand, the thickening effect could work in smoothies or soups. Viva Natural’s fiber supplements are third-party tested to ensure the quality and purity of ingredients.

Best for Daily Use
NOW Foods Psyllium Husk Powder
Pros
- Well tolerated in daily use and helps meet your daily fiber needs
- CGMP-certified

- Fiber per serving: 7 g
- Form: Powder
- Serving size: 1 tbsp
- Third-party tested: Yes
It’s recommended to vigorously mix 1 tablespoon with 12 ounces (oz) of water and drink immediately. Because soluble fiber absorbs water, it could lead to tolerance issues, such as bloating, gas, and abdominal discomfort, if you’re not drinking enough water. “Drink an extra 20-24 oz of water to ensure that bowel movements are able to sufficiently pass and prevent buildup,” says Fencl. NOW Foods Psyllium Husk Powder is also third-party tested and CGMP-certified.

Best Powder
Thorne FiberMend
Pros
- Powder dissolves quickly, with smooth consistency
- Contains prebiotics to support a healthy gut

Key Specs
- Fiber type: Guar gum, rice bran, pectin
- Fiber per serving: 7 g
- Form: Powder
- Serving size: 1 scoop
- Third-party tested: Yes
Note: The powder can settle and become more compact. It’s suggested to “fluff” the powder or you could get fewer servings per container.
As you may have noticed from this list, it’s more common for fiber supplements to come in powder form. In general, powder fiber supplements tend to provide a higher concentration of fiber per serving than capsules. In addition, powders may be more convenient for people who don’t like swallowing pills.

Best Gummy
Best Gummy: Metamucil Fiber Gummies
Pros
- Easier format for people who don’t like powders
- Contains prebiotic
- No added sugars
- Natural orange flavor
Cons

- Form: Gummy
- Serving size: 3 gummies
- Third-party tested: No
There is no added sugar in these gummies, but it does contain a natural sugar alcohol called xylitol. Xylitol is generally well tolerated, but some people may experience digestive discomfort, like gas, bloating, or diarrhea when consuming it. If you have kids at home, be sure to store these gummies out of their reach so that they don’t take more than a recommended serving size.

Best Gluten-Free
Anthony’s Organic Psyllium Husk Powder
Pros
- Batch-tested, verified gluten-free
- Non-GMO
- Certified organic, vegan friendly

Cons
- Lower fiber per serving
- Must drink quickly
Key Specs
- Fiber type: Psyllium
- Fiber per serving: 3 g
- Form: Powder
- Serving size: 1 tsp
- Third-party tested: Yes
Anthony’s Organic Psyllium Husk Powder is batch-tested and verified gluten-free. It may help to promote regularity, improve constipation, and support overall digestion. The powder can be mixed with water or smoothies for a boost of fiber. Just note the packaging suggests drinking the supplement right after mixing because it will thicken and form a gel when it’s allowed to sit.
Psyllium husk is naturally gluten free, but sometimes even products that are naturally gluten free could have cross-contamination when processed in facilities that manufacture gluten containing products or have other ingredients with gluten. The only ingredient is psyllium husk, so if you need to avoid gluten, you can be sure this product is safe.
This supplement has a smaller amount of fiber per serving, partially because it’s a smaller serving size of only 1 teaspoon (tsp). This can be a great option for people who experience some digestive discomfort with fiber supplements. If you want more fiber to get closer to the daily recommended fiber intake, it’s easier to take this supplement a couple of times throughout the day to spread your fiber intake throughout the day so it’s not going through your digestive system at one time.

Comparison Table
What to Look for in a Fiber Supplement
Types of Fiber
When buying a fiber supplement, it’s helpful to look at the different types of fiber.
Insoluble Fiber This fiber isn’t digested and moves through your digestive system whole, adding bulk to stool. Food sources of insoluble fiber include fruits (pears, bananas, prunes), vegetables (leafy greens, broccoli), whole grains (brown rice, quinoa), legumes (beans, lentils), and nuts and seeds.
Examples of soluble fiber in supplements include psyllium husk, wheat dextrin, and inulin while insoluble fiber includes cellulose and lignin. But often foods and supplements with fiber will contain some of both types of fiber, for example, psyllium husk does contain a little bit of insoluble fiber.
Health Goal
When selecting a fiber supplement, you also want to consider what you’re trying to achieve by taking the supplement. If you find it challenging to reach the recommended daily fiber intake, you’ll probably want to consider one of the fiber supplements with more grams of fiber per serving.
But if you’re looking because of a specific health issue, you’ll want to pick up a fiber supplement created for that concern. That could be helping with blood sugar, cholesterol levels, or digestive concerns like constipation, diarrhea, or indigestion.
Third-Party Testing
Nutrition supplements are not regulated by the U.S. Food and Drug Administration (FDA), but supplement companies can choose to have their products third-party tested to verify ingredient quality and purity. It’s generally recommended to try to pick supplements that have been third-party tested. Some products also undergo other certifications like the Certified Gluten Free, Non-GMO, or Vegan.
