Detailed Description:

Based on evidence-based literature on vitamins and minerals, there is a cooperation of a manufacturer multivitamin specifically designed for patients with a gastric band and Roux-en-Y gastric bypass (RYGB). These preparations are the proportions adjusted so that the risk of shortages should decrease and on the other hand, excessive levels of nutrients should be avoided. Main objective of this study is to examine whether these new supplements in particular the number of deficiencies in iron, vitamin B12 and vitamin D can be reduced.
