Prebiotic Fibre Supplements: India Comparison
Inulin, FOS, GOS, chicory root – a clear breakdown of what each type of prebiotic fibre does and the best products available in India for each use case.

Types of Prebiotic Fibres
Prebiotic supplements are classified by their chemical structure, which determines which gut bacteria they feed and how rapidly they are fermented:
- Inulin: Long-chain fructan derived from chicory root. Slowly fermented – less gas than FOS for many people. Selectively feeds Bifidobacterium and Lactobacillus.
- FOS (Fructooligosaccharides): Short-chain fructans – more rapidly fermented by a wider range of gut bacteria. Stronger prebiotic effect, but more gas potential.
- GOS (Galactooligosaccharides): Derived from lactose. The most evidence-backed prebiotic for selectively increasing Bifidobacterium – important for mood and immune function. Added to infant formulas.
- Pectin: Soluble fibre from fruit/vegetable cell walls. Fermented in the colon to produce butyrate. Available from food (apple, guava, citrus peel) more than supplements.
- Resistant starch (RS): Starch that escapes small intestinal digestion. Found naturally in cooked-and-cooled rice, green banana, legumes. Excellent butyrate producer.
Inulin vs FOS vs GOS vs Pectin
| Prebiotic | Best For | Gas Potential | Availability in India |
|---|---|---|---|
| Inulin | General gut health, constipation | Moderate | Good (Neuherbs, Now Foods) |
| FOS | Rapid microbiome feeding, IBS recovery | High initially | Good (in synbiotic capsules) |
| GOS | Bifidobacterium boost, mood/immune support | Low-Moderate | Limited standalone; in synbiotics |
| Pectin | Butyrate production, gut lining | Low | Food sources best; limited supplements |
| Resistant Starch | Butyrate, blood glucose regulation | Low-Moderate | Food sources (rice, legumes) |
Who Benefits Most from Prebiotic Supplements?
- People with consistently low fibre intake (<15g/day) who can't quickly change their diet
- Those recovering from antibiotics – prebiotic fibre accelerates microbiome recovery
- People with low Bifidobacterium (associated with constipation, mood disorders, and weakened immunity)
- Those combining with a probiotic supplement (synbiotic approach) for IBS management
- People managing type 2 diabetes who want glycaemic benefit from prebiotic fibre

FAQ
Q: What is the difference between inulin, FOS, and GOS?
All three are prebiotic fibres but differ in structure. Inulin is a long-chain fructan found in chicory root and garlic. FOS (fructooligosaccharides) are short-chain fructans – more rapidly fermented. GOS (galactooligosaccharides) are derived from lactose and preferentially feed Bifidobacterium. GOS is often considered the most potent prebiotic for Bifidobacterium growth.
Q: Can prebiotic supplements cause bloating?
Yes – prebiotic fibres are fermented by gut bacteria, which produces gas. This is most pronounced in the first 2 weeks and typically subsides as the microbiome adapts. Starting with small doses (2-3g/day) and gradually increasing minimises this effect.
Q: Should I take a prebiotic or probiotic supplement first?
If you have depleted gut bacteria (post-antibiotics, poor diet history), start with a probiotic to repopulate first, then add a prebiotic to feed the new bacteria. For general health maintenance, a synbiotic (both together) or a food-first approach is most practical.
Q: Are prebiotic supplements better than prebiotic foods?
Not necessarily – garlic, onion, chicory, leeks, unripe banana, oats, and legumes provide generous prebiotic fibres. Supplements are most useful when dietary sources are consistently low, or when a therapeutic dose is needed (e.g., 10-15g/day for specific conditions).
