A study led by the IRB CatSud and the HUIPM reviews 122 papers on compounds such as vitamin D3 and magnesium across a range of psychiatric disorders

 

Psychiatric disorders such as schizophrenia, bipolar disorder, major depression, and autism spectrum disorder (ASD) have been linked in recent years to mitochondrial dysfunction—a loss of cellular capacity to produce the energy required for proper functioning. Now, a team from the Institut de Recerca Biomèdica Catalunya Sud (IRB CatSud) and the Hospital Universitari Institut Pere Mata (HUIPM) has led a systematic review on the use of nutraceutical supplements (such as vitamin D3, coenzyme Q10, magnesium, and various B vitamins), which are essential for mitochondrial function, as an adjunctive treatment for these psychiatric conditions.

Considering that the brain consumes approximately 20% of the body’s energy, largely produced within the mitochondria, the research team evaluated whether supplementation targeting this biological pathway could yield clinical benefits. To this end, the researchers reviewed articles published between January 2007 and April 2024. From an initial pool of 2,061 identified records, 122 studies meeting the inclusion criteria were ultimately evaluated.

Among the supplements analyzed, vitamin D3 emerged as the most widely researched across these pathologies. While trials on depression prevention failed to demonstrate an overall effect, individual studies noted improvements in specific subgroups, such as individuals with moderate-to-severe depression or those in the perinatal period. N-acetylcysteine showed more consistent findings across several schizophrenia studies, particularly regarding global symptoms and cognitive functions. The research team emphasizes that: “The findings of this review indicate that certain nutraceuticals could hold a promising role as an adjunctive therapy in psychiatry. However, more robust clinical trials with standardized protocols and validated efficacy biomarkers are required before translating this evidence into clinical practice,” explains Juan Tortajada, lead author of the study and member of the Genetics and Environment in Psychiatry (GAP) group at HUIPM-IRB CatSud-URV.

The authors also highlight the necessity of integrating socioeconomic factors, such as educational attainment and income levels, into future research. These variables can influence access to, adherence with, and continuity of nutraceutical regimens, making them key considerations for designing inclusive strategies in psychiatric care.

 

The study, led by Lourdes Martorell with Juan Tortajada and Bengisu Kevser Bulduk as co-first authors, has been published in the journal General Psychiatry. The research was conducted within the framework of an interCIBER collaboration, involving the Biomedical Research Networking Center in Mental Health (CIBERSAM) and the Biomedical Research Networking Center on Rare Diseases (CIBERER). This joint effort enabled the integration of expertise in mental health with specialized knowledge in mitochondrial pathology. Glòria Garrabou (IDIBAPS, UB, HCB, CIBERER), a co-author who contributed a translational perspective, notes that “this work could ultimately contribute to the development of novel therapeutic approaches for mental disorders that combine conventional pharmacology with nutritional supplementation

A study involving more than 1,500 patients is analysing genetic variants linked to psychiatric disorders and exploring tools to help psychiatrists identify patients with a possible genetic origin of their condition. This work is part of the CESPED project, coordinated by Hospital Universitari Institut Pere Mata (HUIPM) and the Institut de Recerca Biomèdica Catalunya Sud (IRB CatSud, formerly IISPV). The project has a budget of €1.7 million funded by the Instituto de Salud Carlos III (ISCIII) through the European Union’s Recovery and Resilience Facility. In addition, 17 Spanish research groups have participated, including 12 from CIBERSAM. Preliminary results show a frequency close to 3% of microdeletions and microduplications -losses or gains of genetic material- in the Spanish population, which is similar to international studies. The test used combines clinical information, such as psychiatric diagnosis, and also analyses facial features. At present, researchers are still analysing the data and final results are not yet available. However, the study coordinator, Elisabet Vilella -also deputy director of IRB CatSud and head of the Neuroscience and Mental Health area- is optimistic. She explains that “the first results suggest that the frequency of these genetic variants in Spain is around 3%, similar to what has been reported in other countries”. The CESPED project started in 2023 and recently held its final meeting in Barcelona. It was developed in response to growing knowledge about the role of genetics in psychiatric disorders, especially neurodevelopmental conditions. Because these cases are difficult to identify in daily clinical practice, the project aims to develop tools to help professionals detect patients who may have a genetic basis and guide further testing. The research shows that a large part of psychiatric disorders has a genetic component, which can be up to 80% in neurodevelopmental disorders such as autism, ADHD or psychosis. It also shows that between 2% and 5% of patients carry genetic variants caused by gains or losses of genetic material, which may explain the disorder. These changes often affect several genes and organs and can lead to multi-system conditions known as syndromes. For psychiatrists, it is difficult to recognise these cases during a consultation. For this reason, within the CESPED project, a test has been developed to collect key information, such as diagnosis, age of onset, developmental issues, intellectual disability or resistance to treatment. The test also includes a facial photograph to identify specific physical features. The sample The 14 research groups involved in recruitment worked for two years to obtain a sample of 1,555 patients: 471 children and 1,084 adults. Diagnoses include autism spectrum disorder, ADHD, schizophrenia and other psychoses, and bipolar disorder type 1. Different techniques are used to detect genetic variants. Each participant will receive a report, and those with identified genetic changes will be advised to visit a clinical genetics unit for further evaluation.

The intervention will take place on June 4 at 7.30 p.m. at Pavelló dels Distingits of the Hospital Universitari Institut Pere Mata and can also be followed online.

The Filial de Reus de l’Acadèmia de Ciències Mèdiques de Catalunya i Balears organizes, for next Wednesday June 4 at 19.30 pm in the Pavelló dels Distingits of the Hospital Universitari Institut Pere Mata, a talk entitled Eating disorders and addictive behaviors, which will be given by Dr. Fernando Fernandez Aranda, head of section and director of the Unitat de Trastorns Alimentaris i Servei de Psicologia of the Hospital Universitari de Bellvitge IDIBELL, also professor at the Universitat de Barcelona, Fernando Fernández Aranda. He is also in ICREA Acadèmia and deputy director of CIBERobn.
