The Science Behind Fibre Water

Science illustration Science illustration Science illustration Science illustration
The Biology
Fibre regulates gut motility - the contractions that move food through your digestive tract. Without enough, transit slows, gas builds up, and digestion becomes irregular. Prebiotic fibre also feeds beneficial gut bacteria that reduce inflammation and keep your microbiome balanced.
How This Helps
Fibre Water uses Sunfiber® - a certified Low-FODMAP fibre that ferments slowly and gently, so you get none of the gas or bloating that other fibres cause. It forms a soft gel in the gut that smooths digestion, while its prebiotic action feeds beneficial bacteria to restore long-term gut balance.
The Biology
Most Indians get 10–15g of fibre daily - less than half of what's recommended. This gap affects digestion, blood sugar, gut microbiome diversity, and long-term metabolic health.
How This Helps
One serving delivers 5.2g of Sunfiber® in just 12 kcal. No diet overhaul. No extra meals. Just mix in water and drink.
The Biology
Low-fibre meals empty from the stomach quickly, causing a rapid blood sugar drop which the brain reads as hunger. This drives cravings and overeating through the day.
How This Helps
Sunfiber® forms a gel in the stomach that slows gastric emptying, keeping you fuller for longer. It also supports SCFA production - gut signals that tell your brain you've had enough.
The Biology
A healthy gut is responsible for absorbing the nutrients your body converts into energy. When fibre is low, gut bacteria are disrupted, absorption weakens, and cells receive less of what they need leaving you fatigued even when you've eaten enough.
How This Helps
Unlike most fibres, Sunfiber® has been clinically shown to improve absorption of iron, magnesium, and calcium - minerals your body directly uses for energy production. Combined with increased butyrate from its prebiotic action, your gut cells get the fuel they need to work efficiently, so your energy levels reflect what you actually eat.

FAQ

What is Fibre Water?

Fibre Water is a daily drink mix that adds 5.2g of prebiotic dietary fibre to your water. Just mix 1.5 tbsp into a glass of water and drink. It dissolves completely clear with no texture and a clean hint of lemon.

What's in it?

Sunfiber® (partially hydrolysed guar gum). No artificial sweeteners, no preservatives, no fillers.

What is Sunfiber® and why is it different?

Sunfiber® is a certified Low-FODMAP, clinically-studied prebiotic fibre made from partially hydrolysed guar gum. Unlike psyllium husk or inulin, it ferments slowly in the gut — so it works without causing the bloating or gas that most fibre supplements are known for.

Will it cause bloating or gas?

No — this is one of the key reasons we use Sunfiber® specifically. Its Low-FODMAP certification means it doesn't ferment rapidly in the gut, which is the main cause of gas and bloating from other fibres.

When should I take it?

You can take it any time of day. Before meals works well to support fullness and digestion. If you're new to fibre supplementation, start with 1 serving per day and increase to 2 as your gut adjusts.

How much fibre does one serving give me?

Each serving delivers 5.2g of fibre at just 12 kcal. Women need around 25g of daily fibre and men around 38g — count your Fibre Water serving toward that total.

Can I mix it with something other than water?

You can mix it into any drink of your choice like coconut water, protein shake or a light smoothie. It dissolves completely with no texture in any liquid.

How long before I see results?

Most people notice improved digestion and regularity within 1–2 weeks of daily use. Gut microbiome changes from prebiotic fibre typically build over 4–6 weeks of consistent intake.

Is it safe to take every day?

Yes. Sunfiber® is GRAS certified (Generally Recognised As Safe) and is designed for daily use. It has no known side effects at recommended doses.

Is it suitable for people with IBS?

Sunfiber® is certified Low-FODMAP, which is the gold standard for IBS-friendly fibre. However, if you have a diagnosed condition, we recommend consulting your doctor before starting.
