What Is FOS? The Prebiotic Behind Our Sugar-Free Sweetness
31 October 2026
Turn over a pack of Herbaura Moringa Gummies and you will see FOS on the label. It is the reason the gummies taste sweet with no added sugar.
What FOS means
FOS stands for fructooligosaccharides. It is a type of plant fibre found in small amounts in foods such as onions, garlic, bananas and chicory root.
What a prebiotic does
Probiotics are helpful bacteria, and prebiotics are the fibre those bacteria feed on. Your body does not digest FOS the way it digests sugar. It travels to the large intestine, where gut bacteria can use it.
Why we chose it
- It gives a light, natural sweetness.
- It lets us avoid added sugar.
- It adds a prebiotic fibre to a daily gummy.
Good to know
Like other fibres, too much FOS at once can cause gas or bloating in some people. Stick to the serving on the pack.
