BelgiëCombination of probiotics, plant extracts and micronutrients shows positive effects on the integrity of the intestinal barrier
Dysbiosis causes functional gastrointestinal disorders
Multiple studies have shown that a dysbiosis of the intestinal microbiome is associated with various disorders or could even be the cause of such complaints. The following are examples [1]:
- Influence on intestinal motility
- Increased gas production
- Alteration of the gut-associated immune system
- Irritation/inflammation of the intestinal wall
- Damage to the intestinal barrier function

Based on this model, transepithelial electrical resistance (TEER) and paracellular permeability are considered specific and sensitive biomarkers of intestinal barrier integrity and function. Lesions in the cell culture cause a drop in impedance in the TEER test. Treatment with inflammatory stimulants lowered the TEER compared to the untreated control, while pre-treatment with the study drug lowered the percentage resistance to a lesser extent. This resulted in a relative increase in TEER after pre-treatment with the drug complexes compared to the more reduced TEER of the control groups (see Tab. 1). These results were confirmed by determining the fluorescein isothyanate flux through the cell layer following the TEER experiment (see Fig. 1) [3–5].

| Test model | Result | References |
| CaCo-2 monolayer, pre-treatment with complex A, after 24 hours of inflammatory stimulation with LPS-conditioned THP-1 medium | After 3 and 6 hours, the pre-treatment resulted in a slight relative increase in TEER compared to the inflammatory stimulus of the control, p < 0.05 | [3] |
| CaCo-2 monolayer, pre-treatment with complex A, after 24 hours of inflammatory stimulation with LPS | At 21 and 24 hours, pre-treatment increased TEER by 11.43% and 7.78%, respectively, compared to the inflammatory stimulus of the control, p < 0.001 | [4] |
| CaCo-2 monolayer, pre-treatment with complex A, after 24 hours of inflammatory stimulation with INF-γ + TNF-α | After 24 hours, the pre-treatment increased the TEER significantly by 9.46% compared to the inflammatory stimulus of the control, p < 0.05 | [4] |
| CaCo-2 monolayer, pre-treatment with complex B, after 24 hours of inflammation stimulation with LPS | After 24 hours, pre-treatment increased TEER by 10.99% compared to the inflammatory stimulus of the control (personal information1), p < 0.05 | [5] |

Multimodal approach to the treatment of functional gastrointestinal disorders (FGIDs)
The multimodal mode of action of combinations of probiotics, herbal extracts and micronutrients can provide a fast-acting treatment option for FGIDs as well as a good alternative to a single probiotic [3–5]. Future studies based on this principle will clarify whether these combinations could be superior to a single strain of probiotics in the treatment of FGIDs. Chamomilla recutita extract possesses in vitro anti-inflammatory properties besides an antispasmodic and antidiarrhoeal potential and could thus contribute to the positive effect on typical FGID symptoms [6]. Olive oil polyphenols have anti-inflammatory and antioxidant properties which could have a positive effect on inflammatory mediators as well as on the protection of membrane permeability [7]. Vitamins A and D, as micronutrients, generally protect the mucous membranes and the integrity of the intestinal barrier [5].
