Drinking a calorie- and protein-rich formula enriched with arginine, zinc, and antioxidants improved the healing of pressure ulcers in patients who were malnourished, a condition that contributes to the development of pressure ulcers and hinders healing. The 200 patients with stage II, III, and IV pressure ulcers receiving home care services or in long-term care settings were randomly assigned to receive either the enriched formula (400 mL/day) or an isocaloric, isonitrogenous formula for 8 weeks. All participants also received optimal wound care (Cereda E et al. Ann Intern Med. 2015;162:167-174).
