Dietitian-led fibre programme for bloating and constipation, adjusted weekly
TL;DR Fibrecoach pairs a dietitian with a small range of fibre sachets for adults with bloating, constipation or IBS-type symptoms. The mix gets tuned week by week from a symptom diary, not a stool test. Gut clinics refer patients and the patients pay a monthly fee.
Gut trouble is common and most people deal with it at home. Indian community studies put IBS at roughly 4–7.5% of adults, depending on the criteria used[1][2], and one Chandigarh survey found constipation in 16.8% of people[2]. In a rural Haryana study, women were hit harder than men[1].
So do they see a doctor? Mostly not. Only about 29% of urban IBS patients in one study had consulted anyone, and in rural India the share was 17%, with Ayurvedic practitioners consulted more often than allopathic doctors[2].
What people actually do is buy fibre powders and probiotics off the shelf, and nobody checks whether the product suits their symptoms. Some fibres make bloating worse, which is a fun surprise if you bought them to fix bloating.
What it does, in regulatory terms: nutrition and wellness support only. Fibrecoach does not screen for, diagnose or treat any disease. Its sachets are foods under FSSAI's 2022 nutraceutical rules, which forbid claims to treat or cure[3]. A short intake form sends anyone with warning signs, like blood in the stool or weight loss, straight to a doctor.
Here's how it works - a dietitian starts each person on one of five or six pre-made fibre sachets (guar gum, psyllium or resistant dextrin, for example), then adjusts the type and dose every week for 4–8 weeks based on a two-minute symptom diary. Diet advice comes with it. A microbiome test is optional and pitched as education.
The seed wanted custom prebiotic blends designed from gut tests to fix digestion and immunity. I changed that. A review of 11 trials found prebiotics did no better than placebo for IBS overall, and inulin-type fibres raised flatulence[4]. Consensus experts call the evidence for clinical microbiome testing scarce[5]. Tuning by symptoms is cheaper and far easier to defend.
The user is an urban adult, more often a woman, with gut discomfort that won't go away. Today she pays ₹649–949 for a pack of gut sachets from a D2C brand[6], or ₹199–9,999 for a gut test[7][8]. Fibrecoach would charge a monthly fee covering sachets and dietitian check-ins. Gastroenterologists and clinical dietitians are a better channel than cold ads, because they see these patients every day and have no time to coach them.
FSSAI's nutraceutical rules took effect on 1 April 2022 and added guar gum, pectin and resistant dextrin as permitted prebiotics, which ended case-by-case approvals that had taken six to 12 months[3]. A large FMCG company co-led a $10 million round in a gut-supplement brand in December 2022[9], and a 12-month trial published in August 2026 gave the first lasting signal that personalised diets can help IBS[10].
The narrowest figure is India's prebiotics market, which one market research firm puts at US$424.7 million in 2025 (about ₹4,100 Cr)[11]. That covers food, feed and pharma uses, so the supplement slice is smaller. Nobody publishes a figure for personalised gut programmes. The real demand signal is the pile of gut products and tests sold by Indian supplement brands and gut-test startups[6][7][8].
One Indian startup sells a stool-sequencing test with a diet plan, now ₹9,999[7]. Another launched a ₹199 saliva gut scan in 2025 and sells fibre supplements[8]. A large supplement brand sells off-the-shelf fibre and gut sachets through 3,000+ stores[9]. A US gut-testing company is the closest to the seed, with a test-designed prebiotic and probiotic formula[12]. The gap is a clinic-referred programme where a dietitian keeps adjusting fibre type and dose until symptoms settle.

Making the product is the easy bit. The hard part is keeping people on the programme past the first month and getting dietitian time per user low enough to make money, and you also have to write labels and ads that stay inside food-claim rules. Expect the first clinic partners to take two or three months to sign.
Yes, because you sell a food product. The coaching itself needs no licence.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let AI give medical advice or diagnose IBS. It supports the dietitian, and warning signs go to a doctor.

Here's what can go wrong -
I think this is a sensible, low-capital business for a founder with a dietitian network or a gut clinic partner. If you want to sell microbiome tests or a magic formula then skip it. First prove two things - that clinic-referred users stay for three months, and that symptom scores fall for most of them.
My estimate is ₹40–76 L to launch, covering product development, the first sachet runs, dietitians and clinic partnerships. The kit breaks it down line by line.
Yes. The brand owner needs an FSSAI licence or registration, and the product must follow the 2022 nutraceutical rules, with no treat or cure claims.
Yes. The model is the same anywhere, but supplement and claims rules differ a lot, so check your local food regulator before you print a label.

Thinking about building Fibrecoach or something close to it? The make-or-break work is signing clinic partners and keeping users past month three, and that's the kind of thing I help founders figure out. If you need a hand, you know where to find me. Talk to Yash →
