Getting enough fiber is crucial for maintaining a healthy digestive system, stabilizing blood sugar, and regulating appetite. Despite its importance, many Americans don’t meet the recommended daily intake. That’s where fiber supplements can make a big difference.
To help you navigate the vast array of options, the experts at CNET have meticulously reviewed and identified the top fiber supplements of 2025. Here are four standout choices that can boost your fiber intake and support your overall health goals. Let’s review them in detail.
1. Benefiber Original
- Price: $13 at Amazon.
- Form: Powder.
- Serving size: 3 grams of soluble fiber per 2 teaspoons.
This is an excellent choice for anyone on a budget. Made from wheat dextrin, it’s a versatile option that works well in both hot and cold drinks. Whether you’re stirring it into your morning coffee or blending it into a smoothie, this tasteless powder won’t alter flavors or textures. You can even cook with it.
This supplement is ideal for managing blood sugar levels, thanks to its soluble fiber content. However, its lower fiber dose means you might need to use it more frequently compared to other brands.
2. Vitafusion Fiber Well Fit Gummies
- Price: $13 at Walmart.
- Form: Gummies.
- Serving size: 5 grams of soluble fiber per 2 gummies.
For those who dislike swallowing pills, this product offers a fun and tasty alternative. These berry, peach, and strawberry-flavored gummies are packed with fiber and also come fortified with essential B vitamins, folic acid, and biotin. They’re perfect for kids and adults alike.
Although it’s a convenient and flavorful option, keep in mind that it’s not vegan-friendly due to the inclusion of gelatin. However, users rave about its chewability and effectiveness.
3. Spectrum Essentials Organic Ground Chia Seeds
- Price: $11 at Amazon.
- Form: Ground chia seeds.
- Serving size: 4 grams of dietary fiber per 2 tablespoons.
This is a fantastic option for those who prefer natural and food-based fiber sources. These seeds are a whole-food form of fiber and come with the added benefit of omega-3 fatty acids, known to support heart health.
The nutty flavor makes them perfect to add to smoothies, yogurt, or baked goods. However, since they don’t dissolve in liquids, they’re less versatile than traditional powders.
4. NOW Supplements Psyllium Husk Powder
- Price: $17 at Amazon.
- Form: Powder.
- Serving size: 7 grams of dietary fiber (6 grams soluble, 1 gram insoluble) per 2 tablespoons.
This supplement stands out as a potent option for those dealing with constipation. With a blend of soluble and insoluble fiber, it’s a powerful tool for improving digestion. You can mix it into smoothies or even bake it into your favorite recipes.
It also offers a bonus of 8% of your daily iron needs per serving. While its high fiber content is beneficial, it may be too much for some individuals, so it’s best to start with smaller doses and adjust.
