“Nasogastric and Oral Administration of Protein-Rich Drink: Different Insulin and Amino Acid Responses, Equivalent Protein Turnover and Muscle Synthesis”

https://pubmed.ncbi.nlm.nih.gov/38112515

Nasogastric administration of a protein-rich drink increases postprandial insulin and amino acid availability to a greater extent than oral administration, but the resulting whole-body protein turnover and muscle protein synthesis are equivalent between administration routes.
