Nestlé Isosource Energy Vanilla Flavor 500ml is a complete, high-calorie (1.5 kcal/ml) nutritional formula indicated for adults and children over 3 years of age who require a higher energy intake than that provided by conventional food. It is particularly recommended in situations of malnutrition or nutritional risk, convalescence, post-operative recovery, chronic diseases, involuntary weight loss, or difficulties in meeting daily energy needs. Each 500ml pack provides approximately 750 kcal, allowing for a significant increase in energy intake without the need for large volumes of food. The composition presents a balance between carbohydrates, proteins, lipids, vitamins, and essential minerals, and can be used as an exclusive or complementary source of nutrition, as directed by a doctor. The formula contains high-quality proteins from milk, lipids of vegetable origin, and medium-chain triglycerides (MCTs), contributing to an efficient supply of energy. It also includes a complete complex of vitamins and minerals that helps ensure an adequate intake of micronutrients in situations of higher nutritional demand. Gluten-free and clinically lactose-free, this formula is well tolerated by most patients with lactose intolerance. The pleasant vanilla flavor promotes adherence to the nutritional plan and can be consumed fresh between meals or as a meal replacement when recommended by a healthcare professional.
