The detrimental pathophysiology of heart failure (HF) leaves room for physiologic and metabolomic concepts that include supplementation of micronutrients and macronutrients in these patients. Hence myocardial energetics and nutrient metabolism may represent relevant treatment targets in HF. This review focuses on the role of nutritive compounds such as lipids, amino acids, antioxidants, and other trace elements in the setting of HF. Supplementation of ferric carboxymaltose improves iron status, functional capacity, and quality of life in HF patients. To close the current gap in evidence further interventional studies investigating the role of micro- and macronutrients are needed in this setting.
