Clinical nutrition has become an important part of current American medicine, comprising a range of medicinally produced foods intended for consumption by patients that are unable to cover their nutritional requirements from ordinary food due to certain medical reasons. It comprises enteral feeding formulations, parenteral nutrition, oral nutritional supplements, and infant nutrition products for medical infants.
It has altered the way U.S. hospitals and healthcare facilities manage patient recovery and treatment. An increase in the number of patients with chronic diseases, frequent hospitalizations of senior citizens, and the importance of nutritional therapy in the clinical outcomes are some factors driving its demand. Abbott Nutrition will launch its Ensure Plant-Based Protein supplement in 2024, which is a 20-gram portion of plant-based protein.
The U.S. Clinical Nutrition Market was valued at approximately USD 12.76 billion in 2025 and is projected to reach around USD 21.57 billion by 2035, driven by CMS reimbursement structures, a growing cancer patient population, and the aging population's rising malnutrition risk. Globally, the Clinical Nutrition Market was valued at USD 34.06 billion in 2025 and is expected to reach USD 57.64 billion by 2035, expanding at a CAGR of 5.36% during the forecast period of 2026–2035.
