Clinical-use summary

What it is and when it may be considered

GastroNYX Plus is a food supplement based on Aloysia triphylla and an Ajuga reptans cell-culture extract, both used for digestive function, with Althaea officinalis supporting a soothing and emollient effect on the digestive tract.

Positioning

Nutritional support

It may be considered as an adjunct nutritional option, within an appropriate diet and after clinical assessment, in subjects with:

  • gastroesophageal reflux even in the presence of lesions, erosions or micro-ulcerations and heartburn;
  • functional dyspeptic complaints, slow digestion, post-prandial fullness, bloating and gas;
  • reduced mucosal comfort or irritative symptoms involving the oro-gastrointestinal tract [1].
What it is not

It does not replace therapy

This page does not present GastroNYX Plus as a pharmacological alternative to PPIs or other treatments. The product is not positioned as an antacid and is not intended to diagnose, treat or cure disease. Use should always be framed within professional clinical judgement [1][6].

Directions for use

Practical schedule

1 tablet per day, to be swallowed or, in case of reflux, to be dissolved in the mouth. In this case, after taking it, avoid food or drinks for approximately 15 minutes in order to promote a topical action and not wash out the active molecules of GastroNYX. Take preferably in the morning upon getting up or in the evening before going to bed: in case of pharmacological therapy with PPIs or alginates, take GastroNYX apart (for example, PPIs in the morning and GastroNYX in the evening). There is no pharmacological interference but the indicated drugs create a barrier that makes it more difficult for the active molecules of GastroNYX to act on the mucosa. It can be taken both on a full and empty stomach [1].

Rationale

Why the rationale is not centred on pH

The product rationale rests on three complementary pillars:

  • mucosal comfort and protection, due to the mucilage fraction of Althaea officinalis;
  • digestive support, consistent with the traditional use of Aloysia triphylla / triphylla in dyspeptic and gastrointestinal complaints [2];
  • biological interest in the modulation of pro-inflammatory and oxidative mediators described for acteoside and, in other literature, for teupolioside [1][3][4][5].

In practical terms, this medical page frames the product as nutritional support focused on mucosa, digestive function and a phytonutritional rationale, rather than as a simple acid-neutralising approach.

Scientific evidence

Literature supporting the rationale

The evidence summarised below includes preclinical studies and technical/regulatory documents on individual compounds or extracts relevant to the product profile. References are reported transparently and should not be read as definitive clinical proof for the finished product [1][2][3][4][5].

acteoside

Modulation of pro-inflammatory pathways

The review by Alipieva et al. describes acteoside as a phenylethanoid glycoside with antioxidant and anti-inflammatory activities. More recent literature, also reflected in the ISF technical sheet, discusses interactions with NF-κB, TNF-α, IL-1β, COX-2, iNOS and pathways such as MAPK e PI3K/AKT [1][3].

Traditional use of Aloysia

Recognised digestive context

The EMA assessment report on Aloysia triphylla describes a history of traditional use in the digestive area, including dyspepsia, gastrointestinal complaints, stomach ache and indigestion [2].

Mucosal integrity

Preclinical experimental data

In an animal model of 5-FU-induced mucositis, acteoside attenuated increases in inflammatory and tissue-damage biomarkers, alongside histological improvement across the gastrointestinal tract, from the oesophagus to the colon [5].

Total gastric lesion area in the cold-restraint stress model
Figure 1. Selected data from Table 2 in López-Rodríguez et al. In the cold-restraint stress gastric ulcer model, total gastric lesion area was 47.36 ± 9.80 mm² in the vehicle group and 0.05 ± 0.02 mm² in the acteoside 1 mg/kg group; the comparator misoprostol was 0.06 ± 0.01 mm². The figure is provided for informational purposes as support for the biological rationale of acteoside and is not clinical evidence on the finished product [4].
Reading the figure

What the preclinical model suggests

López-Rodríguez et al. evaluated fractions and isolated compounds in an experimental stress-induced gastric lesion model. In that setting, acteoside markedly reduced ulcerated area, with inhibition close to 99.8% compared with the vehicle group [4].

Correct interpretation: the finding is useful because it confirms the gastroprotective interest of acteoside in a preclinical setting; however, it refers to an animal model, not to direct clinical evidence on the marketed product.
2025 acteoside study

Reasoned summary of the 5-FU mucositis model

In the 2025 Medical Oncology study, 5-fluorouracil induced widespread biochemical and histological alterations in the gastrointestinal tract. acteoside attenuated these changes, with a trend towards better outcomes at the higher dose [5].

ParameterEffect of 5-FUReported effect of acteoside
TNF-α, IL-1βIncreaseAttenuation of the increase [5]
MMP-1, MMP-2, MMP-8IncreaseReduction / attenuation [5]
TIMP-1DecreaseTrend towards recovery [5]
ALP, AST, LDHIncreaseAttenuation [5]

Traditional use and regulatory context

What the EMA report adds on Aloysia triphylla

The EMA/HMPC report on Aloysia triphylla provides regulatory and historical context for interpreting the formulation. The document refers to traditional uses associated with:

  • dyspepsia and gastrointestinal complaints;
  • stomach ache and indigestion;
  • antispasmodic / digestive use in traditional literature [2].

Value of the data: it supports the digestive-use coherence of Aloysia within the formula, while remaining distinct from specific clinical proof in reflux disease.

Use caution in transplant recipients undergoing immunosuppressive therapy, as the active ingredients in GastroNYX have immune-modulating properties.
Food supplements should not be used as a substitute for a varied, balanced diet and a healthy lifestyle. Keep out of reach of children under 3 years of age. Excessive consumption may have laxative effects. Store in a cool, dry place [1].
