Fiber is one of the most important nutrients we need in our bodies. It helps us properly digest food as well as regulate our sugar levels and usage. However, most people don’t get nearly enough fiber — only around 5% of the US population meet the requirements. Fiber supplements are an easy way to meet your nutritional needs and keep your digestion on track.

Best budget fiber supplement

Benefiber Original

Benefiber Original is wheat dextrin, a byproduct of milling wheat. It takes our spot as the best budget fiber supplement thanks to its low cost and versatility. However, that low price means it has less fiber per serving than other brands.

Benefiber only has soluble fiber, which makes it a great option for people who want to use a fiber supplement to manage their blood sugar. Soluble fiber dissolves in water and is good for both diarrhea and constipation, while insoluble fiber helps with constipation. This fiber supplement is tasteless and dissolves easily in cold and hot liquids. Or you can add it to food while you cook — it won’t thicken or add a flavor. 

Pros:

  • Affordable
  • Available in on-the-go packets
  • Flavorless and sugar-free

Cons:

  • Lower dose of fiber
  • No third-party certifications

Additional details

  • Price: $
  • Form: Powder 
  • Serving size: 3 grams of soluble fiber per 2 tsp
  • Supply: 62 days
