Multivitamin and multimineral food supplement. It has been formulated following the recommendations of scientific societies of bariatric surgery. Nutritional deficiencies are very common in people undergoing bariatric surgery. The main vitamins deficient before surgery are: vitamin A, vitamin D, thiamine, cyanocobalamin, folic acid, and vitamin C. Regarding minerals, iron, zinc, selenium, and copper deficiencies are very common in the bariatric preoperative period. How to use: 1 Capsule daily. Follow the nutritionist's instructions. Swallow with water. Because our Barimix contain both water-soluble and fat-soluble vitamins, it's generally recommended to consume them with a meal. This can improve the absorption of certain nutrients while reducing the risk of gastrointestinal discomfort, which can otherwise occur when taking a multivitamin on an empty stomach. It's not recommended to take them with dietary supplements and calcium-rich foods.
