Information

Product Description

Finally. FOS Prebiotic Fibre is a smart, plant-based sweetener that delivers a gentle, natural sweetness while actively supporting digestive health and overall wellbeing.

Made from Fructo-oligosaccharides (FOS), a naturally occurring prebiotic fibre derived from plants, it helps nourish beneficial gut bacteria, promoting a balanced and healthy digestive system. With approximately one-third the sweetness of sugar, it’s ideal for anyone seeking a subtle, mild flavour that complements both sweet and savoury creations.

Use it in baking, smoothies, yoghurts, hot drinks, sauces, or even when blending with other sweeteners to boost fibre content and improve taste balance. Its clean flavour and prebiotic benefits make it a versatile and intelligent addition to any modern kitchen.

Why Choose Finally. FOS?

  • 0 Glycaemic Index suitable for low-carb and keto lifestyles
  • Sugar-free & 100% Plant-Based
  • Supports gut health and digestion
  • High in Fibre: 92.5g per 100g
  • 33% as sweet as sugar: mild, clean, and naturally smooth taste

Finally. FOS is more than just a sweetener; it’s sweetness with purpose. A natural, functional ingredient designed to nourish your body while keeping your recipes wholesome and delicious.

Sustainability at heart: All our packaging is 100% recyclable.
