Strains, fibres and enzymes from a gut health supplement manufacturer
Custom probiotic, fibre, digestive enzyme and botanical supplements for brands go from the first formula to the finished product in our UK facility, where we develop and make them as a gut health supplement manufacturer. We make capsules, tablets, powders, sachets and stick packs, gummies and liquids, with each probiotic specified to the strain and to the count it must hold at the end of shelf life, fibre in gram doses and enzymes sold on declared activity. Every batch comes with a certificate of analysis and a batch release confirmation, and your brand owns the formula.
In the International Food Information Council's online survey of about 1,000 US adults in May 2026, 64% called gut health a high or extremely high priority, and 30% said they had supported it over the past year by eating more fibre (IFIC, August 2026).
Seven gut health products that stand out now
Seven product types stand out.
- Defined-strain probiotics. Capsules, sachets and gummies built on named strains at the count their trials used, including spore-forming strains that survive heat and synbiotics that pair a strain with a fibre. Our probiotic supplement manufacturing page covers strains, counts and stability.
- Fibre and prebiotic blends. Inulin, psyllium, partially hydrolysed guar gum and resistant starch in sticks, powders and gummies, including blends for people eating less while using GLP-1 medicines. See fibre and prebiotic supplement manufacturing.
- Digestive enzymes. Lactase carries an authorised claim. Protease, amylase and lipase blends, and fruit enzymes such as bromelain and papain, do not, so their labels state content and activity.
- Fermented-food formulas. ISAPP defines fermented foods as foods made through desired microbial growth and enzymatic conversions of food components (Marco and colleagues, 2021). In a randomised diet study in 36 healthy adults, a diet high in fermented foods increased gut microbiota diversity, while a high-fibre diet did not change it over the study period (Wastyk and colleagues, Cell, 2021). Brands bring that story into capsules and powders with defined cultures, and into live fermented drinks, which we also make in-house.
- DAO enzyme products. Diamine oxidase (DAO) is the enzyme that breaks down histamine from food. As of October 2026, it is an authorised novel food in GB and the EU, as protein extract from pig kidneys, for food supplements as enteric coated pellets in capsules or as enteric coated tablets, at up to 0.9 mg of DAO a day. The authorisation covers the porcine source only, which rules out halal, kosher and vegetarian positioning.
- Gut-brain and gut-skin formulas. Psychobiotics, probiotics studied for mood and stress, sit at the research frontier. A 2026 scoping review of 30 human studies found that the evidence does not yet establish a reproducible, biomarker-mediated pathway from these interventions to emotional improvement (Dai and colleagues, Frontiers in Nutrition, 2026). For skin, a 2022 meta-analysis found no significant effect on skin hydration from lactic acid bacteria taken alone (Sun and colleagues, Frontiers in Nutrition, 2022). These formulas take their claims from nutrients: vitamin B6 and magnesium contribute to normal psychological function, and biotin to the maintenance of normal skin.
- Seaweed actives. Fucoidan extract from the brown seaweed Fucus vesiculosus is an authorised novel food, at up to 250 mg a day in food supplements on the GB register (FSA, 2025). Seaweed also brings iodine at variable levels and cadmium, which has its own limit of 3.0 mg/kg in supplements made mainly from dried seaweed, so we specify both and check each lot.
Every project runs through the same development stages: brief, evidence review, formulation, bench samples, blind sensory panels, a pilot batch on production equipment, stability in the final pack, and scale-up into routine production. Each stage leaves a record you keep.
Every gut active screened for novel food status first
We specify every active by form, grade and dose, and screen each one for novel food status in-house against the public registers before a formula is fixed. Human milk oligosaccharides (HMOs) and lactoferrin and colostrum have their own pages, as do postbiotics, Akkermansia, liver health and oral health.
Probiotics
Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host (Hill and colleagues, 2014). Many benefits belong to specific strains, so we specify genus, species and strain, and set the count the product must still hold at the end of shelf life. The EU novel food catalogue lists bacteria by species, and some are not novel only in food supplements, so the format decides which strains a product can use.
Fibres and prebiotics
Fibres carry the largest set of authorised gut claims: chicory inulin and the oat, barley, rye and sugar beet fibres each have register wording and conditions of use, shown in the claims table below. ISAPP defines a prebiotic as a substrate that is selectively utilised by host microorganisms conferring a health benefit (Gibson and colleagues, 2017). On a label, though, regulators such as the FSAI regard "prebiotic" as a health claim, and no prebiotic claim is authorised (FSAI guidance).
Digestive enzymes
Lactase is the one enzyme with an authorised claim: "Lactase enzyme improves lactose digestion in individuals who have difficulty digesting lactose". It applies only to food supplements with at least 4,500 FCC units, taken with each lactose-containing meal, and the label must say that tolerance to lactose is variable and that users "should seek advice as to the role of this substance in their diet". Other enzyme blends sell on declared activity, measured by Food Chemicals Codex methods where they exist.
Binding proteins and adsorbents
Lactoferrin, the iron-binding milk protein, and colostrum, with its immunoglobulins, belong here too; both need milk allergen labelling. Activated charcoal is the one adsorbent with an authorised claim: "Activated charcoal contributes to reducing excessive flatulence after eating", for food with 1 g per quantified portion, and the label says the effect comes with 1 g taken at least 30 minutes before and 1 g shortly after the meal.
Botanicals and nutrients
Ginger and fennel carry no authorised claim in GB or the EU, so labels state content. Nutrients complete the claims plan: "Calcium contributes to the normal function of digestive enzymes", and "Chloride contributes to normal digestion by production of hydrochloric acid in the stomach", a claim that cannot be used for chloride from sodium chloride.
Acid-resistant capsules, fibre powders and spore-former gummies
The active decides the format.
- Capsules carry probiotics, enzymes and DAO. HPMC shells hold far less water than gelatine, and acid-resistant or enteric coated options protect acid-sensitive strains and enzymes; see capsule manufacturing.
- Powders carry gram doses of fibre, often with spore-forming probiotics that tolerate processing; see powder supplement manufacturing.
- Sachets and stick packs deliver one measured serving of fibre, or one probiotic dose, in high-barrier film.
- Gut health gummies suit spore-forming probiotics, modest fibre doses and nutrients, with the serving count set honestly; heat and water in gummy processing kill most lactic acid bacteria, and every gummy batch gets an active assay as standard. See gummy manufacturing.
- Liquids and shots suit botanical and fibre drinks, and dispensing caps keep a probiotic powder dry until opening.
We make every format above in our UK facility, which is ISO 9001, HACCP and GMP certified by BSI, and FDA registered. Capsules, gummies and liquids are GMP certified. For retail programmes: BRCGS implementation under way, certification expected in early 2027.
Keeping cultures cold and blends dry
- Approve and receive. Each culture, fibre and enzyme comes from an approved supplier, and its certificate of analysis is checked against our specification on receipt.
- Store and dispense. Live cultures stay chilled or frozen, as the producer's specification sets, and are dispensed under humidity limits; our allergen management plan, with yellow colour coding, controls milk and soy.
- Blend. Cultures go into dry, low water activity excipients with an overage set from stability data, and fibres blend in a set order and time, so every capsule, scoop and stick carries its dose.
- Fill and seal. Capsules are filled and checked by weight, and powders and sticks are sealed into high-barrier packs, with desiccant where the format needs it.
- Label and release. Label verification on every batch is the critical control point in our HACCP plan, and quality control releases each batch against its specification.
Live counts, fibre and enzyme activity tests
Every batch is tested by accredited partner laboratories (ISO/IEC 17025) as part of every order, then released against its specification; see testing and batch release. The panel, set for each product and market, covers live counts in CFU for probiotics, fibre by AOAC methods, enzyme activity, water activity and microbiology, including Salmonella. Every batch comes with a certificate of analysis and a batch release confirmation, and development adds the formula, the specification, stability data and a claims review for each market.
Why probiotic counts as a claim, and which gut claims are authorised
Gut claims follow the register, not the research. The table sets out the position as of October 2026, from the GB nutrition and health claims register, the EU register and US law.
| Market | Claims you can use | Conditions and what to avoid |
|---|---|---|
| Great Britain | "Chicory inulin contributes to normal bowel function by increasing stool frequency". Oat grain, barley grain and sugar beet fibre each contribute to an increase in faecal bulk, and "Rye fibre contributes to normal bowel function". Lactase for lactose digestion, activated charcoal for flatulence after eating, and calcium and chloride for digestion. | At least 12 g a day of native chicory inulin with a mean chain length of 9 or more; grain and beet fibre claims only on foods high in that fibre; the lactase and charcoal doses above. "Probiotic" is regarded as a health claim, acceptable only with a closely related authorised claim beside it (CAP, 2024), and none exists for probiotic supplements. |
| European Union | The same authorised wording and conditions. | The European Commission regards "probiotic" as a health claim, but at least eight member states, including Italy, France, Spain and the Netherlands, accept the term under national conditions (EHPM, 2024). |
| United States | Structure and function claims, such as support for digestive health, backed by competent and reliable scientific evidence, notified to FDA and carrying its standard disclaimer. "Probiotic" is common on labels. | No medical claims. FDA does not define "probiotic" as a regulatory category, and its draft guidance lets labels add a count of live cells in CFU beside the required weight. |
One formula can serve all three markets when it is built for them from the start: a fibre or nutrient at the dose its GB and EU claim needs, an evidence file for US claims, and label copy written for each market.
Akkermansia in EU and US formulas, and Bacillus coagulans in supplements
As of October 2026, these are the rules that change what gut health brands can make and sell. We review each line every quarter, and our regulation watch tracks the detail.
- Akkermansia. Pasteurised Akkermansia muciniphila is an authorised novel food in the EU, for adults at up to 34 billion cells a day and for adolescents from 12 at lower limits by age. It is not yet authorised in Great Britain, so it goes into EU and US formulas.
- Spore probiotics. In the EU, Bacillus coagulans, now named Heyndrickxia coagulans, is not novel in food supplements but novel in other foods, so we use it in capsules, powders and gummies sold as food supplements.
Your formula is yours, including its specification, test plan and stability data. Start your project with your strain, fibre or enzyme, your format and your markets, and we build the claims plan with the formula.

Questions brands ask
What does a gut health supplement manufacturer do?
A gut health supplement manufacturer develops and produces probiotic, fibre, enzyme and botanical supplements for brands. At British VitaTech that covers formulation, strain and fibre selection, novel food screening, manufacture, testing and the label claims for the UK, EU and US. We make capsules, tablets, powders, sachets, gummies and liquids in-house. R&D is a paid stage that can be included with an order of the right size, and your formula is yours.
Can a gut health supplement say "probiotic" on the label?
Not on its own in GB, or in EU markets that follow the European Commission's view. CAP's advice, citing DHSC guidance, regards "probiotic" as a health claim that needs a closely related authorised claim beside it, and as of October 2026 none is authorised for supplements. At least eight EU member states, including Italy, France and Spain, accept the term under national conditions, according to EHPM. The term is common on US labels, and labels in every market can name the strains.
Which gut health claims are authorised in the UK and EU?
Fibres and a few nutrients and enzymes carry them. "Chicory inulin contributes to normal bowel function by increasing stool frequency" needs 12 g a day, and oat grain, barley grain and sugar beet fibre contribute to an increase in faecal bulk in foods high in that fibre. Lactase, activated charcoal, calcium and chloride carry digestion claims at set conditions. As of October 2026, no claim is authorised for probiotics, prebiotics or other digestive enzymes.
Which formats work for gut health supplements?
The active decides the format. Capsules suit probiotics, enzymes and DAO, with acid-resistant or enteric options for sensitive actives. Powders, sachets and stick packs carry gram doses of fibre. Gummies suit spore-forming probiotics and modest fibre doses, and liquids suit botanical and fibre drinks. We make every format in our UK facility, which is ISO 9001, HACCP and GMP certified by BSI, and capsules, gummies and liquids are GMP certified.
Can you make DAO enzyme supplements?
Yes, within the novel food authorisation. As of October 2026, DAO is authorised in GB and the EU as protein extract from pig kidneys, for food supplements as enteric coated pellets in capsules or enteric coated tablets, at up to 0.9 mg of DAO a day. The label describes the enzyme and its content, because no DAO health claim is authorised. The authorisation covers the porcine source only, which rules out halal, kosher and vegetarian positioning.
Can gut health supplements make mood or skin claims?
Not for the strain itself. Research on the gut-brain and gut-skin axes is active, but a 2026 scoping review of 30 human studies found that the evidence does not yet establish a reproducible, biomarker-mediated pathway from these interventions to emotional improvement, and as of October 2026 no probiotic mood or skin claim is authorised in GB or the EU. Brands add nutrients with authorised claims, such as vitamin B6 or magnesium for normal psychological function and biotin for normal skin.
Do you make private label gut health supplements?
We develop bespoke gut health supplements rather than relabelling stock blends. Private label puts your logo on a catalogue formula; a bespoke formula lets you choose the strain, fibre, dose and format, match the claim to each market and control your supply. R&D is a paid stage that can be included with an order of the right size, and your formula is yours, including its specification and test plan.
