Healing wounds requires more protein than usual because amino acids are needed for collagen synthesis, tissue repair, immune function, and enzyme activity. Stage 3 and 4 ulcers are deep, draining wounds with significant tissue loss and inflammation, which increases protein turnover and nitrogen losses. Because of this, protein needs rise to support healing and prevent negative nitrogen balance. The recommended range is 1.5–2 g of protein per kilogram of body weight per day, which provides enough amino acids to fuel tissue repair without overloading the system. For example, a 70 kg person would target about 105–140 g of protein daily. Keep in mind that staying energy-replete is important too; adequate calories help spare protein for healing rather than using it for energy. Lower protein ranges would not meet the heightened demands of these wounds, while even higher amounts (2.0–2.5 g/kg) offer little additional benefit and may not be necessary, especially if there are renal concerns.
