The U.S. medical foods market size was estimated at USD 6.9 billion in 2025 and is projected to reach USD 10.7 billion by 2033, growing at a CAGR of 5.5% 2026 to 2033. This growth is driven by the rising geriatric population, growing prevalence of chronic diseases, and increasing adoption of disease-specific nutritional formulas.
The growing prevalence of chronic diseases further accelerates demand for disease-specific nutritional interventions. According to the data published by the Centers for Disease Control and Prevention in April 2025, approximately 194 million U.S. adults, which is 76.4%, reported at least one chronic condition, while over 51% had multiple chronic conditions. Among older adults, the burden is even higher, with nearly 93% of individuals aged 65+ having at least one chronic disease in 2023. Neurological conditions such as Alzheimer’s are particularly significant, with about 7.2 million Americans currently living with the disease, and projections indicating continued growth. This rising disease burden creates sustained demand for medical foods as adjunct therapy in clinical treatment pathways.
The rising incidence of chronic and rare diseases, along with advances in targeted therapies, is driving demand for disease-specific medical foods. These products are increasingly used in the management of conditions such as cancer, gastrointestinal disorders, and metabolic diseases, where tailored nutrition is essential to support treatment outcomes and avoid drug-nutrient interactions. For instance, gastrointestinal patients require easily digestible, tolerance-focused formulas, while oncology patients benefit from high-protein, energy-dense solutions to manage treatment-related complications. Leading companies such as
- Abbott Osmolite 1.2 / 1.5 Cal: A fiber-free enteral formula designed for patients with gastrointestinal intolerance, supporting nutrient absorption and tolerance in sensitive patients.
- Danone Milupa Product Range: Foods for Special Medical Purposes (FSMPs) intended for the dietary management of inherited metabolic disorders, supporting growth and nutrient requirements under medical supervision.
- Nestlé BOOST SOOTHE: A clear, high-calorie oral nutritional supplement designed for patients experiencing oral discomfort, taste changes, or mucositis, particularly during cancer treatment. It provides 300 kcal and 10 g of protein per serving, in a soothing, easy-to-drink format, to help maintain weight and nutrition.

Route of Administration Insights
The oral segment accounted for the largest revenue share of the U.S. medical foods market in 2025. Nutrient and vitamin administration via the oral method is widely practiced across healthcare institutions in the U.S., with products available in various forms such as liquids, powders, puddings, pills, and pre-thickened formulations. Most patients requiring Oral Nutritional Supplements (ONS) are treated using standard products with a calorific value of 1.5 to 2.4 Kcal/mL, offered in multiple flavors to improve patient compliance.
This mode of administration is convenient, cost-effective, and highly preferred, which has driven its widespread adoption. In addition, the rising prevalence of chronic diseases and increasing demand for patient-friendly, easy-to-consume nutritional solutions, particularly among pediatric and geriatric populations. For instance, in March 2026, Nestlé introduced Compleat Paediatric Oral Blends, an oral nutritional supplement in an on-the-go pouch designed for children with specialized medical nutrition needs, highlighting the increasing focus on convenient and specialized oral formulations.
The enteral segment is expected to grow at the fastest CAGR during the forecast period. Enteral formulas are designed for diverse patient groups, including geriatric and pediatric populations, and are regulated by the U.S. Food and Drug Administration to ensure quality and safety. Growth is driven by the rising prevalence of chronic diseases such as cancer and cardiovascular disorders, which limit oral intake. In addition, advancements in feeding devices and the introduction of easy-to-administer formulations are supporting increased adoption across healthcare settings in the U.S.

The powdered form of medical foods accounted for the leading revenue share of 35.4% in 2025. Medical food products are extensively available in powder form that can be easily administered via the enteral or oral route by combining them with water or milk, as per the directions of the physician. Increasing consumer preference for powdered formulas, driven by their ease of use, is encouraging manufacturers to develop new product categories. Companies such as Danone, Abbott, and Nestlé have developed a range of medical foods in powdered form that address various nutritional requirements, disorders, and deficiencies.
The liquid-formulated medical food segment is anticipated to grow at the fastest CAGR from 2026 to 2033. Liquid products are administered to patients diagnosed with dysphagia or when there are limitations to their oral physiology. Moreover, these formulations are widely adopted by the geriatric and pediatric populations when solid formulations are not possible or are limited.
