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.

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.

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

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.

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.

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.

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.

Nutrient Optimiser is designed for anyone who invests time and money into eating well and wants to make the most of it. It is particularly suited to those who take their nutrition seriously, whether through quality food choices, regular supplementation or both, and want to ensure their body is actually absorbing and using what they put in.

DigeZyme® is a patented multi-enzyme digestive complex. It is included in Nutrient Optimiser to support the efficient breakdown of food so that nutrients are released and available for absorption by the body.

Nutrient Optimiser is designed to support three key stages of how your body processes food, breaking food down at the enzyme level, supporting the gut environment where absorption takes place, and helping your body access the nutrients released from food. It is not about eating more; it is about getting more from what you already eat.

Nutrient Optimiser is a digestion and absorption supplement from Reflex Nutrition, designed to support how your body processes and uses the nutrients in food. It is built around three independently patented, clinically studied ingredients, DigeZyme® digestive enzyme complex, LactoSpore® probiotic and BioPerine® black pepper extract, each targeting a different stage of the digestion and absorption process.
