Table 3: Contributions of the macroalgae samples _Ultra_ sp., _Gracilaria multipartite_, and _Sargassum muticum_ from Buarcos and _S. muticum_ collected from San Marcos to the recommended daily intake (RDI) for an adult. from Buarcos provides the recommended daily intake (%RDI) of these minerals for an adult, with concentrations of 21.20%, 12.60%, 29.40%, and 16.60%, respectively. With regard to Mg, our findings also indicated that the RDI of Mg in _S. muticum_ from San Marcos (36.7%) was higher than in all of the Buarcos species. Furthermore, [PERSON] et al. [37] confirmed that the _S. muticum_ species is also capable of providing substantial quantities of Mg (40.1%), as we did in our study (36.7%). K was another crucial mineral found in the brown macroalgae of San Marcos, with 8 g providing 19.7 per cent of the recommended daily intake for an adult. Among the Buarcos species, the highest values for the recommended daily intake of sodium and magnesium were observed in _Ulta_ sp. (29.5% and 33.0%), followed by _S. muticum_ (29.4% and 29.1%) and _G. multipartita_ (25.6% and 16.8%) in 8 g of dried algae. The values for P, Zn, and Mn are very low in RDI. P was the most prevalent in _G. multipartita_ (2.30%), exhibiting a higher of RDI percentage than the other seaweeds. Mn and Zn are the trace elements with the highest concentration in brown seaweeds, but they represent only 1.48 per cent and 0.45 per cent of the RDI, respectively. Seaweeds are therefore uliparti as a valuable source of nutrients and minerals for human health.
