Abstract: A method for providing nutritional supplement information for a subject is proposed, including a sequence of steps in given order and repeated at least once after a time span of at least 2 days or one week for adapting the provided nutritional information: A) taking a sample from the subject; B) analyzing said sample to determine the nutritional status; C) based on the results calculation of nutritional supplements to improve the nutritional status; D) providing individualized nutritional supplement information. This sequence involves the prediction of at least one initial characteristics matrix and multiplication of this matrix weighted with factors, with an initial recommendation vector for the calculation of a target profile vector after a given first time interval from the profile vector as determined in step B), and in each following cycle adaptation by adapting at least one of the characteristics matrix and the weighting factors.
