Digestive comfort products we make, from lactase to peppermint oil
Our UK facility formulates and makes custom digestive comfort supplements for premium brands, and as a digestive supplements manufacturer we build them on lactase at the 4,500 FCC units or more that its authorised claim requires, digestive enzyme blends declared by activity, activated charcoal at the full 1 g serving its claim fixes, ginger specified by its gingerols, peppermint oil specified to its European Pharmacopoeia monograph, and gentle fibre blends. Each goes into the format that suits it: capsules, chewable and swallowable tablets, powders, sachets and stick packs, liquids and shots, or gummies. Every batch is tested by accredited partner laboratories, and declared enzyme activity is measured at release and confirmed to the end of shelf life.
Digestive comfort is the everyday side of gut health and sits within our gut health supplement manufacturing range. In the Rome Foundation's survey of 51,425 adults in 26 countries, nearly 18% reported bloating at least weekly over three months (Ballou and colleagues, Gastroenterology, 2023).
We also make digestive comfort products as nutrition for people using GLP-1 medicines, rather than a GLP-1 effect: smaller servings, fibre that is gentle to build up, hydration and formats that suit a smaller appetite. A joint advisory from four US medical and nutrition societies counts the management of gastrointestinal side effects among the nutrition priorities for people using these medicines (Mozaffarian and colleagues, 2025), and our GLP-1 support supplement manufacturing page covers the full range.
We specify every active by source, grade and activity, and screen each one in-house against the novel food registers of your target markets before a formula is fixed.
Lactase and digestive enzymes
Lactase from the mould Aspergillus oryzae works at the acid pH of a meal in the stomach, while lactase from the yeast Kluyveromyces lactis works near neutral pH and suits use in milk itself. The authorised lactase claim counts activity in Food Chemicals Codex (FCC) units, so we specify the assay that matches the enzyme. Broad-spectrum blends combine protease, amylase and lipase, each declared by activity rather than weight: protease in HUT, amylase in DU and lipase in FCC lipase units. Fruit enzymes add protein-splitting activity: bromelain from pineapple stem and papain from papaya.
Activated charcoal
Activated charcoal is carbon from coconut shell, wood or other plant material, activated with steam at high temperature to open a dense network of fine pores. Grade decides performance, so we specify the source, particle size and adsorption power, and test each lot against its pharmacopoeial monograph. It is also the one adsorbent with an authorised digestive claim, which fixes the dose at 1 g per quantified portion.
Ginger, peppermint and fennel
Ginger root and its extracts are specified by their pungent gingerols, measured by HPLC. Peppermint oil is specified to its European Pharmacopoeia monograph, which sets ranges for menthol, menthone and menthofuran and caps pulegone. Fennel seed rounds out warming blends. None of the three carries an authorised claim in GB or the EU, so labels state content. In the UK, peppermint medicines with digestive indications hold product licences or traditional herbal registrations (MHRA, 2025), and our food supplements never borrow those indications.
Fibres, live cultures and postbiotics
Fibre supports regular digestion, but the wrong fibre at the wrong dose causes the very gas a comfort product sets out to avoid. In a controlled crossover trial in 26 healthy adults, up to 10 g a day of native inulin and up to 5 g of oligofructose were well tolerated, while oligofructose at 10 g gave the largest rise in symptoms, mainly flatulence and bloating (Bonnema and colleagues, 2010). We favour slow fermenters such as partially hydrolysed guar gum and acacia gum, split servings and build-up directions, as our fibre and prebiotic supplement manufacturing page explains. Named strains come from our probiotic supplement manufacturing range, and heat-inactivated strains from postbiotic supplement manufacturing.
Debloat names need an authorised claim beside them, such as charcoal's
Digestive comfort claims follow the register. As of October 2026, these are authorised in GB and the EU, in this wording and with these conditions:
| Active | Authorised claim | Conditions |
|---|---|---|
| Lactase | "Lactase enzyme improves lactose digestion in individuals who have difficulty digesting lactose" | Only food supplements with at least 4,500 FCC units, taken with each lactose-containing meal; 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". |
| Activated charcoal | "Activated charcoal contributes to reducing excessive flatulence after eating" | Only food with 1 g of activated charcoal per quantified portion; the label says the beneficial effect is obtained with 1 g taken at least 30 minutes before and 1 g shortly after the meal. |
| Live yoghurt cultures | "Live cultures in yoghurt or fermented milk improve lactose digestion of the product in individuals who have difficulty digesting lactose" | Only yoghurt or fermented milk with at least 100 million CFU of live starter microorganisms (Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus) per gram, so it suits a fermented dairy drink rather than a capsule. |
| Calcium | "Calcium contributes to the normal function of digestive enzymes" | Only food that is at least a source of calcium, as the nutrition claim defines it. |
Ginger, peppermint, fennel and enzyme blends other than lactase carry no authorised claim in either market. A product name built on "debloat" can be read as a health claim, so it needs a related authorised claim beside it, such as the charcoal claim at its full dose. In the US, labels carry structure and function claims, such as support for healthy digestion, backed by competent and reliable evidence and FDA's standard disclaimer, and never a medical claim. Our claims and regulation page covers each market in depth.
Directions from the claim, and enzymes kept active to expiry
Dose and timing
Claim conditions set the dose and the directions. Lactase is taken with each meal that contains lactose, and activated charcoal works as 1 g at least 30 minutes before a meal and 1 g shortly after it. We write those directions onto the label and size each serving to deliver them. One gram of a light, porous powder fills several capsules, so a stick pack or a compressed tablet often suits charcoal better.
Keeping enzymes active
Enzymes are proteins, and heat, moisture and acid unfold them. We add enzymes to dry blends at room temperature, compress tablets with only the force their hardness target needs, and keep enzymes out of cooked gummy masses. Acid-resistant capsules or enteric coating carry acid-sensitive enzymes past the stomach. Activity falls over shelf life, so we set an overage from stability data and confirm the declared activity at the end of shelf life, not only at release.
Botanical chemistry
Gingerols readily dehydrate to shogaols, a reaction driven by heat and pH, with the greatest stability near pH 4 (Bhattarai and colleagues, Journal of Pharmaceutical Sciences, 2001). Ginger shots and drink mixes are therefore built close to that pH, with as little heat as the process allows. Peppermint oil is volatile, so we fill it into sealed, acid-resistant capsules that release it after the stomach rather than in it.
Compatibility and interactions
Activated charcoal adsorbs many substances, other actives included, so we keep it apart from vitamins, enzymes and botanicals in a formula, and labels advise taking it apart from medicines. Sweeteners matter too. Polyols such as sorbitol and xylitol ferment in the gut, and once added polyols exceed 10% the label must warn that excessive consumption may produce laxative effects. We sweeten with steviol glycosides or sucralose instead, and mask the bitter notes of enzymes and ginger in flavour development. Any allergen an enzyme preparation carries, such as milk or soy from its carrier, is declared under our allergen management plan, with yellow colour coding.
Lactase at the table, charcoal in a stick, ginger in a shot
The active and the moment of use decide the format.
- Capsules carry lactase, enzyme blends, peppermint oil and botanical extracts, in HPMC or acid-resistant shells. Our capsules are GMP certified; see capsule and tablet manufacturing.
- Chewable and swallowable tablets suit lactase and enzymes taken at the table, and compressed charcoal. We make tablets in-house, with hardness and disintegration checked through every run.
- Powders, sachets and stick packs carry a full 1 g charcoal serving, gentle fibre blends and ginger drink mixes in one measured dose; see powder supplement manufacturing.
- Liquids and shots suit ginger and botanical drinks built near pH 4, and our liquids are GMP certified.
- Gummies suit ginger and modest fibre doses, while enzymes go into tablets and capsules. Gummies are GMP certified and every gummy batch gets an active assay as standard.
Every format is made in our UK facility, which is ISO 9001, HACCP and GMP certified by BSI, and FDA registered. Your formula is yours: the specification, the activity targets and the stability data belong to your brand.
Charcoal in a dust-controlled area, with a validated clean-down
- Brief and claims plan. We agree the customer, the markets and the claim first, because the claim sets the dose and the directions.
- Specify and approve. Every material comes from a supplier that has passed our supplier approval, with a review every year. Each lot arrives with a certificate of analysis giving enzyme activity, adsorption power or marker content.
- Weigh and blend. Materials are weighed against the batch record in controlled humidity, with enzymes added to dry blends at room temperature. Charcoal runs in a dust-controlled area with a validated clean-down, because fine carbon marks everything it touches.
- Fill, compress or pack. Capsules are filled and checked by weight, tablets compressed to hardness and disintegration targets, powders filled into sticks or tubs, and shots filled and sealed.
- Label and release. Label verification on every batch is the critical control point in our HACCP plan, CCP-01, and covers the claim directions. Three retained samples per batch are kept for shelf life plus one year, and nothing is dispatched without quality control sign-off.
Enzyme activity a digestive supplements manufacturer proves at expiry
Ask how label activity is proved at the end of shelf life. Every batch is tested by accredited partner laboratories (ISO/IEC 17025) as part of every order, and your specification sets the release tests:
- Enzyme activity: FCC methods for lactase, protease, amylase and lipase, at release and at each stability time point.
- Activated charcoal: adsorption power and purity against its pharmacopoeial monograph, with heavy metals.
- Botanicals: identity by HPTLC fingerprint, gingerols by HPLC and the peppermint oil profile by gas chromatography.
- Live cultures: counts by plate count or flow cytometry, so the label count holds to the end of shelf life.
- Purity and stability: lead, cadmium, mercury and arsenic, microbiology to the specification for each format, and accelerated and real-time stability studies on every new formula.
Our quality system adds a HACCP study per product type, reviewed annually, and a full mock recall, forward and backward with mass balance, in seconds; our testing and batch release page sets out the full approach. R&D is a paid stage that can be included with an order of the right size. Start your project with your actives, your format and your markets, and we will build the formula and the claims plan together.

Questions brands ask
What does a digestive supplements manufacturer make?
A digestive supplements manufacturer develops and produces lactase, enzyme, activated charcoal, botanical and fibre products for brands. At British VitaTech that covers formulation, activity and dose targets, novel food screening, manufacture, batch testing and label claims for the UK, EU and US. We make capsules, tablets, powders, stick packs, liquids and gummies. R&D is a paid stage that can be included with an order of the right size, and your formula is yours.
Which digestive comfort claims are authorised in the UK and EU?
As of October 2026, four claims apply in GB and the EU. Lactase improves lactose digestion in individuals who have difficulty digesting lactose, at 4,500 FCC units with each lactose-containing meal, and the label notes that tolerance varies. Activated charcoal contributes to reducing excessive flatulence after eating, with 1 g at least 30 minutes before a meal and 1 g shortly after. Live cultures in yoghurt or fermented milk carry a lactose digestion claim, and calcium contributes to the normal function of digestive enzymes.
Can a supplement claim to reduce bloating?
Not in those words in the UK or EU. As of October 2026, no authorised claim mentions bloating; the closest is activated charcoal's claim on reducing excessive flatulence after eating, which needs 1 g per portion and the full directions on the label. A product name built on "debloat" can be read as a health claim, so it needs a related authorised claim beside it. US labels use structure and function claims, such as support for healthy digestion, with FDA's disclaimer.
How do you keep digestive enzymes active to the end of shelf life?
We protect them from heat, moisture and acid at every step. Enzymes go into dry blends at room temperature, tablets are compressed with only the force their hardness target needs, and acid-sensitive enzymes travel in acid-resistant capsules or enteric coating. We set an overage from stability data, measure activity by FCC methods at release and through stability, and confirm the declared activity at the end of shelf life, not only at release.
Can you make digestive comfort products for people using GLP-1 medicines?
Yes, as nutrition for people using GLP-1 medicines, rather than as a GLP-1 effect. These customers eat less, so we build smaller servings, slow-fermenting fibres that are gentle to build up, hydration and formats that suit a smaller appetite. Claims stay with nutrition: nothing on the label refers to GLP-1 or to the medicine's side effects. Our GLP-1 support supplement manufacturing page covers protein, fibre and micronutrient products for the same customers.
Can ginger and peppermint supplements make digestive claims?
No. As of October 2026, ginger, peppermint and fennel carry no authorised health claim in GB or the EU, so labels state the plant, the part, the extract and its content. In the UK, peppermint medicines with digestive indications hold product licences or traditional herbal registrations, and our food supplements never borrow those indications. Brands add an authorised nutrient claim, such as calcium for the normal function of digestive enzymes, to carry the health message.
Which formats suit digestive comfort supplements?
The active and the moment of use decide. Capsules suit lactase, enzyme blends and peppermint oil; chewable tablets suit enzymes taken at the table; stick packs deliver a full 1 g charcoal serving or a gentle fibre dose; and liquids and shots suit ginger. Gummies suit ginger and fibre but not enzymes. Every format is made in-house, and our capsules, gummies and liquids are GMP certified.
