96% of UK adults don’t meet the recommended 30g of daily fibre (Source: National Diet and Nutrition Survey 2019-2023). Fibre Superblend is an unflavoured high-fibre powder built around four plant-based fibre sources, each contributing to the variety of fibre in your diet: 

1. Bamboo fibre: a source of insoluble fibre that adds bulk 

2. Chicory root fibre: a natural prebiotic that acts as food for beneficial gut bacteria 

3. Green banana flour: rich in resistant starch, which passes undigested to the large intestine where gut bacteria ferment it 

4. Roasted carob powder: a natural source of soluble fibre that contributes to feelings of fullness and satiety 

The formula also contains four live cultures, heat-treated postbiotic microflora, and vitamins and minerals including: 

1. Chromium, which contributes to the maintenance of normal blood glucose levels 

2. Calcium, which supports the normal function of digestive enzymes 

3. Chloride, which contributes to normal digestion by aiding the production of hydrochloric acid in the stomach 

Each 8g serving provides 5.6g of fibre and only 16 calories. 

KEY BENEFITS 

Increase your fibre intake – top up your diet with a balanced blend of soluble and insoluble fibres. Each serving provides 5.6g of fibre from four different sources.

HOW TO USE

Add one heaped 15ml scoop (8g) to shakes, juices or smoothies. This will thicken the drink slightly — add extra water to reach your preferred texture.

Increase your intake gradually to allow your gut to adjust:

- Week 1: one serving per day

- Week 2: two servings per day

- Week 3 onwards: up to three servings per day

Drink an additional one to two glasses of water per day when increasing your fibre intake. Do not exceed three servings (24g) per day.

This product is a food supplement and should be used in conjunction with a varied and balanced diet and a healthy lifestyle, not as a substitute for such. Not intended for use by anyone under 16. Keep out of reach of young children.

Frequently Asked Questions

What you need to know

No. Fibre Superblend is a food supplement. It is not intended to diagnose, treat, cure or prevent any disease. If you have a health condition or take medication, consult your GP before use.

Yes. The unflavoured powder is designed to stack with your existing routine — add it to your protein shake, morning smoothie or any drink. It’s compatible with Nutrient Optimiser, which supports digestion and absorption, and works well as part of a broader longevity stack.

The UK government recommends 30g of dietary fibre per day for adults. Average intake for men is around 21g — approximately 70% of the target. Each 8g serving of Fibre Superblend provides 5.6g of fibre, contributing meaningfully to closing that gap.

Increasing fibre intake quickly can cause temporary bloating, gas or digestive discomfort as your gut bacteria adjust. Starting with one serving per day and increasing over two to three weeks gives your digestive system time to adapt. Staying well hydrated helps significantly.

Chromium contributes to the maintenance of normal blood glucose levels — an authorised claim on the GB Nutrition and Health Claims Register.

Most fibre supplements are built around a single source: psyllium husk, inulin or acacia. Fibre Superblend contains four different plant-based fibre sources: bamboo, chicory root, green banana and carob. It includes prebiotics, live cultures and postbiotic microflora, making it a more complete gut formula than a single-source fibre powder.

Postbiotics are heat-treated preparations of beneficial microorganisms. Unlike live probiotics, they don’t require refrigeration and are stable in powder form. This formula uses heat-treated postbiotic microflora alongside four live cultures.

Different fibre structures are fermented by different gut bacteria. Eating a broader variety of fibre types gives a wider range of beneficial bacteria something to feed on — which supports a more diverse gut microbiome. Most people eat the same rotation of foods, which limits the variety of fibre they consume. Four sources in one formula is one practical way to address that.
