Exploring the Impact of Extended Amino Acid Supplementation on Body Composition and Psychopathology in Patients with Eating Disorders Undergoing Psycho-Nutritional Rehabilitation
Article in Endocrine, metabolic & immune disorders drug targets, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEating disorders are frequently linked to protein-energy malnutrition, resulting from chronic energy intake reduction, and leading to reduced body weight and altered body composition. A nutritional approach based on the supplementation with a mixture of essential amino acids has proven effective in conditions characterized by reduced dietary intake and increased degradation of endogenous proteins and might also contribute to correct the amino acid deficiency possibly involved in the pathogenesis of eating disorders.
objectiveThis study aimed to explore the effects of amino acid supplementation in conjunction with a standard psycho-nutritional rehabilitation program on body composition, symptoms and psychopathology status in 30 female patients with eating disorders hospitalized at the Residenza Palazzo Francisci in Todi, Italy.psychopathologic state.
methodsEnrolled patients were divided in two groups receiving amino acid supplementation for 45 and 90 days, respectively. Each patient underwent bioelectrical impedance analysis at baseline, after 45 days and after 90 days. Validated psychometric tests were administered at study entry and study end to all enrolled patients.
resultsResults from bioelectrical impedance analysis suggest that amino acid supplementation contributes to restoring nutritional and metabolic balance, with effects proportional to the duration of administration. Conversely, interpreting the effects on psychopathologic state and symptoms was challenging, probably due to the small sample size and short observation period.
conclusionsProlonged amino acid supplementation may play a role in the management of patients with eating disorders, favoring the correction of the catabolic state and possibly contributing to improvement of the psychopathologic state.
