About this study
Official title: EVALUATION OF A NEW SUPPLEMENT ON NUTRITIONAL STATUS IN CHILDREN WITH FOOD ALLERGY
Allergic diseases are rising globally. By 2025, over half of the European population is projected to be affected by some form of allergy, with the highest rates among infants and young children. This growing prevalence also has a significant economic impact, resulting in more than 100 million lost work and school days each year due to allergic conditions.
Allergies arise from a breakdown in immune tolerance mechanisms. Current research suggests that the development is influenced by genetic, environmental, and gene-environment interactions, leading to immune system dysfunction, partly mediated by epigenetic mechanisms. Various factors have been proposed as contributors to FA onset. Among the unchangeable risk factors are male sex, race/ethnicity (with higher risks among Asian and Black children compared to White children), and genetics (familial associations, HLA, and specific genes).

Modifiable risk factors also play a role, with growing evidence showing that environmental influences, such as the use of antibiotics, antiseptic agents, and a high-fat, low-fiber diet, negatively affect microbiome composition. Additional risk factors potentially affecting FA onset include atopic diseases (such as comorbid atopic dermatitis), increased hygiene, vitamin D deficiency, reduced consumption of omega-3 polyunsaturated fatty acids and antioxidants, the use of antacids (which hinder the digestion of allergens), obesity, and the timing and route of food exposure (increased risk with delayed oral ingestion of allergens coupled with environmental exposure). The microbiome also plays a critical role in these processes.
Currently, no Food and Drug Administration (FDA)-approved treatment exists for FA, and the standard approach is strict dietary avoidance of the triggering allergens. As a result, the nutritional burden of elimination diets can be substantial, leading to risks such as growth failure, micronutrient deficiencies, and feeding challenges with long-term consequences.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 17 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
body growth parameters (time frame: after 6 months of treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06751810, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Dec 2025; AzTrials last refreshed its copy on 8 Nov 2026.
