Why do I need fiber?​ ​

As one of the most vital human organs, maintaining the health of our gut is important to lead a healthy life.* Gut regulates metabolism, immunity, brain, weight, and happiness.* In this fast-moving world, people started moving towards delicious and easily cookable foods, which demand the use of refined and polished grains. Polished grain may be good in taste but contains minimal fiber. But, adequate fiber intake is essential for a healthy gut as they support regular bowel movements and maintain a healthy gut microbial environment.*

Sandhu’s Prebiotic Fiber is family-friendly, easy to add to meals, supports healthy living for all ages with Joy & Bonding

Why Sandhu’s Prebiotic Fiber?​

Our unflavored prebiotic fiber mixes rapidly in your favorite beverages or bakes without changing its flavor, color, texture, or aroma which makes your gut care routine easy and comfortable. ​

    Frequently Asked Questions

    1. Is SunFiber a prebiotic?

    Yes, SunFiber is classified as a prebiotic fiber that supports the growth of beneficial gut bacteria and helps maintain a healthy digestive environment. Many researches shows that SunFiber help increases beneficial bacteria like Bifidobacteria and Lactobacillus while maintaining a comfortable digestive experience.

    • It is made from partially hydrolyzed guar gum (PHGG), a plant-based soluble fiber derived from guar beans.
    • Unlike many common fibers that ferment quickly and cause discomfort, SunFiber ferments very slowly in the colon, which helps ease common issues like bloating and gas.
    • It also supports gut balance by enhancing microbial diversity and supporting a strong gut barrier for digestive wellness.
    • Because it is gentle, SunFiber can be used daily, even by people with sensitive digestive systems.

    2. Is SunFiber gluten-free and low-FODMAP?

    Absolutely. SunFiber is gluten-free, organic, and is certified low-FODMAP—making it ideal for digestive-sensitive consumers. Unlike many other fibers, it is easy for the body to digest and does not cause any digestive upset even in sensitive stomachs.

    3. Can it help both constipation & diarrhea?

    Yes—it’s known as a “true regulating” fiber. SunFiber works gently in both directions. It adds bulk to loose stool, while also helping bind water and making hard stools easier to pass. This dual action supports healthy bowel movements, making it ideal for everyday digestive comfort.

    4. How much fiber per serving?

    SunFiber provides around 7 grams of soluble fiber per scoop, which supports regularity and gut health. It offers a gentle, well-tolerated source of fiber that fits easily into your daily routine—without adding any fillers or sweeteners.
