Oral Proteins and Peptides Market to Reach USD 15.6 Billion by 2034

Proteins and peptides represent one of the most promising classes of therapeutic agents, offering highly specific mechanisms of action that enable targeted treatment of diseases ranging from diabetes and cancer to autoimmune and metabolic disorders. Traditionally, however, these biologics have been limited by their delivery routes-primarily injectables-due to their poor stability and absorption in the gastrointestinal tract.

In recent years, breakthroughs in oral protein and peptide drug delivery technologies have begun to transform this landscape. By overcoming barriers such as enzymatic degradation and low intestinal permeability, companies are developing innovative oral formulations that enhance patient convenience, adherence, and therapeutic outcomes. This shift is especially critical for chronic conditions like diabetes, where frequent injections remain a major barrier to compliance.

According to Exactitude Consultancy, the oral proteins and peptides market was valued at USD 6.9 billion in 2024 and is projected to reach USD 15.6 billion by 2034, growing at a CAGR of 8.5%. This reflects the convergence of drug delivery science, biotechnology, and patient demand for more accessible therapies.
