By Route of Administration – Enteral Leads and Records the Fastest Growth
According to Shubham Padhi, Research Analyst at 6Wresearch, with 61% of route of administration revenue in 2025, Enteral was the largest category. Enteral administration holds the largest share as it is essential for patients who cannot consume food orally, particularly in hospital settings. This method effectively addresses the unique dietary requirements of individuals with severe metabolic disorders, ensuring they receive the necessary nutrition. Its lead should widen, with a projected CAGR of 16.5% during 2026–2032, the highest in this split. The enteral route is poised for rapid growth due to an increasing number of diagnoses for conditions such as phenylketonuria, which necessitates specialised nutritional support. As awareness rises and more patients are diagnosed, the demand for enteral products will continue to strengthen, further solidifying its market position. Suppliers should focus on enhancing their enteral product offerings to meet the rising demands of healthcare facilities.
By Product – Liquid Leads, Powder Expected to Grow Fastest
Liquid took 53% of product revenue in 2025, more than any other category. Liquid formulations dominate the market as they are preferred for ease of consumption, especially among children with rare diseases. Their widespread use in hospitals contributes to their substantial market share. The quickest growth will come from Powder, forecast to expand at a CAGR of 20.0% between 2026 and 2032. Powder products are experiencing the fastest growth due to their flexibility in dosage and administration, appealing to caregivers managing complex dietary needs. This trend indicates a shift towards more adaptable nutritional solutions. Buyers may benefit from exploring a wider range of powder products to accommodate varying patient requirements.
By Application – Phenylketonuria Leads, Tyrosinemia Expected to Grow Fastest
The largest application category in 2025 was Phenylketonuria, at 49% of revenue. Phenylketonuria products lead the market as they are critical for managing dietary restrictions in affected individuals, with a notable patient population in Japan. Their established use in clinical settings reinforces their dominant position. Over 2026–2032, Tyrosinemia is expected to post the fastest growth, at a CAGR of 20.1%. Tyrosinemia products are growing quickly due to an increase in diagnosed cases, highlighting the need for specific nutritional interventions. This growth reflects a broader awareness and focus on rare metabolic disorders. Suppliers should consider investing in research and development for tyrosinemia products to capture the expanding market.
By Sales Channel – Institutional Sales Leads, Online Sales Expected to Grow Fastest
In 2025, Institutional Sales led the sales channel split with a 50% share.
