This study aimed to characterize the nutritional composition of <i>C. cylindracea</i> comprehensively. Samples were collected from the Northern Adriatic and analyzed for proximate composition, amino acids, minerals, vitamins, and fatty acids using standardized laboratory methods. The results revealed a balanced proximate profile with notable protein (11.8 g/100 g DW) and fiber (24.4 g/100 g DW) levels and relatively low carbohydrates (11.6 g/100 g DW). The seaweed exhibited a rich mineral content, including high levels of iron, magnesium, manganese, and potassium, while toxic heavy metals were absent. Vitamins B12 and E were present at elevated concentrations compared to related species. Amino acid analysis showed a well-balanced essential amino acid profile supporting its nutritional value. The high salt content (33.8 g/100 g DW) suggests the need for desalination prior to consumption to reduce sodium intake risks. These results indicate the potential of this invasive species as a novel dietary component, particularly for populations who may benefit from plant-based marine sources of essential nutrients in the Mediterranean region. This is the first comprehensive nutritional characterization of <i>C. cylindracea</i> from the Adriatic Sea, highlighting its potential for valorization as both an environmental management strategy and a novel dietary resource.Foods (Basel, Switzerland)&lt;i&gt;Caulerpa cylindracea&lt;/i&gt;: First Insight into Its Nutritional Potential.PMC12469415HORIZON-MSCA-2022-CITIZENS-01(dr.
