The invention relates to a bioactive composition which is characterised in that it comprises: a calcium concentration (Ca2+) of more than 350 mg/l, a magnesium concentration (Mg2+) of more than 1200 mg/l, a sodium chloride concentration (NaCl) of less than 3500 mg/l, and a potassium concentration (K+) of less than 450 mg/l. The inventive composition is also characterised in that it has a pH of between 1.5 and 6.5, preferably between 4.3 and 6.5 and, in particular, 5.5. In addition, the invention relates to a method of preparing one such composition based on seawater, which is characterised in that it comprises the following steps consisting in: selectively demineralising the seawater by means of electrodialysis; acidifying the solution thus obtained, involving the dissociation of the water with the aid of ion transfer through ion-exchanger membranes, and concentrating the solution thus obtained by means of nano filtration. |
