Key Features

Supports Digestion & Regularity*

Psyllium husk absorbs water in the gut, forming a gel-like substance that softens stools and facilitates their passage through the intestines, thereby promoting regular bowel movements [1].

Contributes to Feeling Full*

Psyllium husk expands in the stomach upon absorbing water, promoting a feeling of fullness [2]. It also slows nutrient absorption, allowing nutrients to reach the distal small intestine. This delayed delivery stimulates GLP-1 secretion [3], which plays a key role in supporting satiety and appetite regulation.

Prebiotic Boost

FOS are rapidly fermented by gut bacteria [4], providing immediate nourishment for beneficial microbes. In contrast, Fibersol® ferments slowly [5], supporting a sustained release of short-chain fatty acids (SCFAs), essential for colon health.

Where fiber flows, vitality grows. Fibersentials FLOW provides pure, effective fiber to help you bridge your fiber gap effortlessly.

Key Features

Advanced Fiber Blend with Complementary Kinetics

Each fiber in this blend is selected for its unique properties: psyllium husk forms a gel that delivers nutrients to the distal small intestine; FOS is rapidly fermented [4], particularly benefiting the proximal colon; and Fibersol®’s slow fermentation [5] supporting microbial balance and SCFAs production in the distal colon. Together, they deliver comprehensive, health-promoting effects throughout the entire gut.

FRUCTO-OLIGOSACCHARIDES (FOS)

A shorter-chain version of inulin, FOS is a rapidly fermenting prebiotic that promotes the growth of beneficial gut bacteria, including Bifidobacteria [6]. Typically found in fruits and vegetables, our FOS is derived from chicory root.

FIBERSOL®

A thermally and enzymatically treated corn starch, classified as resistant starch type 4, consisting of α(1-4), α(1-6), (1-2) and (1-3) glycosidic linkages [7]. Approximately 50% of Fibersol® is fermented by gut bacteria (including Bifidobacteria) [8], while the other half increases stool volume by being excreted. A soluble, slowly fermenting fiber, Fibersol® supplies a sustained prebiotic boost and its intake leads to SCFAs production [9].

PSYLLIUM HUSK

Psyllium is a dietary fibre consisting primarily of highly branched arabinoxylans (arabinose and xylose polymers). It forms a viscous gel that retains water throughout colon, increasing stool water content, forming a soft, bulky mass that is easier to pass.

Fibersol® is a soluble dietary fiber produced by ADM/Matsutani Singapore Pte., Ltd.

How to use

  • Mix 1 serving (2 levelled-off scoops) with 1–2 glasses of water, juice or milk. Stir well and drink immediately. You can also mix it into yogurt or smoothies, but always follow with a large glass of water.
  • You can take more than one serving per day, adjusting your intake based on your fiber needs. Each leveled scoop provides 2.8 g of fiber, and 2 scoops (1 serving) provides 5.6 g of fiber to help you bridge your fiber gap.
  • Drink plenty of water when consuming FLOW and stay hydrated throughout the day (1.5-2 liters daily).
  • Do not use if you have difficulty swallowing or a history of esophageal narrowing.

Closing the Fiber Gap—Made Simpler

Historically, our ancestors consumed close to 100 g of fiber per day [10]. Today, modern diets fall drastically short: Netherlands 21 g/day [11], UK 19 g/day [12], US 17 g/day [13], Asia 8–10 g/day [14].

Women often face an even wider gap. In the Netherlands, 10% of men and just over 5% of women meet the recommendation [15]. In the UK, only 4% of women and 13% of men [12] reach it.

In the Netherlands, the recommendation is 30 g/day for women and 40 g/day for men [15]. Evidence shows that going even higher, toward ~45 g/day, can increase short-chain fatty acid (SCFA) production and promotes the activity of fiber-degrading enzymes in the gut microbiome [16,17].

It’s not about filling that gap with fiber supplements alone. Real, whole foods: vegetables, fruits, legumes, whole grains, are the foundation (we’ll share more practical strategies in our blog). Fibersentials FLOW is a fiber gut health supplement to help make that journey easier. Each serving adds 5.6 g of fiber: dense, convenient, and designed to complement—not replace—your daily efforts.

Why? Because even small, steady changes help you cross the line and your gut will thank you for it.

How is Fibersentials FLOW different?

We all know psyllium helps soften stools, relieve constipation, and promote satiety—but FLOW is more than just psyllium. This fiber gut health supplement combines fast- and slow-fermenting fibers, using psyllium as a delivery vehicle to provide complete digestive and microbiome support.

It depends on your goal. For general fiber support, start with ½ or 1 serving (1 scoop = 2.8 g fiber or 2 scoops = 5.6 g fiber) and adjust as needed. If you’re targeting specific needs like relieving constipation or supporting satiety, you may benefit from 4–6 scoops daily. Start low and build gradually.

We always use a level scoop for accuracy. Heaped scoops vary too much to be reliable.

Yes, mix into yogurt, smoothies, or porridge. Just follow with water.

Take it during the day with plenty of hydration. Avoid taking it right before bed.

Mild discomfort can happen when increasing fiber intake or introducing new fibers. Start with a smaller amount (e.g. 1 scoop daily), let your gut adjust for 1–2 weeks, and then increase gradually.

Psyllium has a unique dual action: it softens hard stools when you’re constipated and can help firm loose stools. Its gel-forming properties help normalize bowel movements rather than trigger diarrhea. Just remember to stay well-hydrated for best results.

We recommend at least 1.5 to 2 liters of water daily to help the fibers work properly and reduce the risk of intestinal discomfort.

FLOW contains only pure, water-loving fibers—no anti-clumping agents. To prevent lumps, sprinkle gradually while stirring. Blending into smoothies also works well.

Absolutely. FLOW complements probiotics perfectly. Its prebiotic fibers nourish beneficial gut bacteria, helping them thrive.

As with any supplement, we recommend speaking with your healthcare provider before using Fibersentials FLOW during pregnancy or breastfeeding.

Fibersentials FLOW is formulated with adult needs in mind. However, psyllium husk is commonly recommended by healthcare providers for children, particularly for constipation support. If you’re considering it for your child, we recommend discussing it with your healthcare professional to ensure the right guidance for their specific needs.

Yes, Fibersentials FLOW contains only plant-based ingredients and is suitable for both vegetarians and vegans.
