In 2025, the study published in International Journal of Molecular Sciences examined several medicinal plants used to support gut health. Among them were fennel and ginger, two ingredients found in Digelit.
The review brought together studies on their relationship with the gut microbiota, inflammation, oxidative stress and antimicrobial activity. These mechanisms help explain why both extracts are used in formulations designed for digestive wellbeing.
Fennel and ginger are two botanicals of interest for digestion
Fennel, Foeniculum vulgare, and ginger, Zingiber officinale, were two of the plants included in the review. Both have a long history of digestive use and are also studied for their characteristic compounds and their possible role in gut health.
When choosing a supplement, it is also important to look at the form in which these plants are used and how well their extracts are characterised.
Not all botanical extracts are the same
A concentrated extract is different from simply using powdered plant material. The extraction ratio indicates how much plant material is used to obtain one part of extract.
For example, a 4:1 ratio means that four parts of plant material are used to produce one part of extract. In Digelit, fennel is provided as a 4:1 dry seed extract and ginger as a 10:1 dry root extract.
These ratios help show how concentrated an extract is, but there is another detail that is even more useful when assessing its composition: standardisation.
5% gingerols shows what the ginger extract actually provides
Standardisation indicates the amount of specific characteristic compounds present in an extract. This gives a clearer picture of its composition and helps maintain greater consistency between batches.
The ginger extract in Digelit is standardised to 5% gingerols, one of the most studied groups of characteristic compounds naturally found in ginger.
That is why comparing two supplements only by the number of milligrams can be misleading. It is also useful to check whether a concentrated extract is used and, especially, whether its standardisation is stated.
Nutribiolite Digelit combines selected extracts and digestive enzymes
Digelit combines fennel and ginger with DigeZyme®, bromelain and gentian root extract, bringing together several ingredients associated with digestion in one formula.
DigeZyme® provides amylase, protease, lactase, cellulase and lipase. These enzymes are involved in breaking down carbohydrates, proteins, lactose, plant fibres and fats.
The formula also includes bromelain, derived from pineapple, and gentian, a plant traditionally used to support digestion.
Digelit therefore combines digestive enzymes with botanical extracts defined by their concentration and, in the case of ginger, also by their standardised gingerol content.
What to look for when choosing a digestive supplement
A well-designed formula can also be assessed by the quality and characterisation of its ingredients. It is useful to consider the ingredient form, extract concentration, standardisation and the amounts provided.
Digelit brings these elements together in a formula with concentrated botanical extracts, ginger standardised to 5% gingerols and a blend of five digestive enzymes.
Digelit combines fennel, ginger standardised to 5% gingerols, DigeZyme®, bromelain and gentian in a complete formula for digestive wellbeing.
A formula for those looking for more than a simple blend of botanicals
Digelit brings together selected botanical extracts, digestive enzymes and standardisation that makes it easier to understand what the ginger in the formula actually provides.
If you are looking for a complete formula to complement your digestive routine, Digelit combines fennel, ginger standardised to 5% gingerols, DigeZyme®, bromelain and gentian in one supplement.
Frequently asked questions about Digelit
How is Digelit related to the study?
Digelit contains extracts of Foeniculum vulgare and Zingiber officinale, two of the species analysed in the scientific review.
What does a 4:1 or 10:1 extract mean?
The ratio indicates how much plant material is used to obtain one part of extract. For example, 10:1 means that ten parts of plant material are used to produce one part of extract.
Why is it important that the ginger is standardised to 5% gingerols?
Because standardisation shows the proportion of specific characteristic compounds present in the extract and provides more information about its composition than the total amount of extract alone.
What does DigeZyme® provide?
DigeZyme® combines amylase, protease, lactase, cellulase and lipase, enzymes involved in the breakdown of different nutrients during digestion.
How should Digelit be taken?
Take one capsule twice a day with sufficient liquid before the main meals. It is not recommended for children under 12, or for pregnant or breastfeeding women.
