Postprandial, Healthy individuals, Amino acid, Bioavailability, Protein
Brief summary
This study assesses the amino acid concentrations in subject serum after intake of different types of proteins. The study is divided in two consecutive sub-studies. Subjects will be asked to ingest a specific protein blend each visit in a randomized order, after which blood will be drawn on 14 different time points. At least 48 hours will be kept between each visit, and the subjects receive a follow up call within 4-14 days after visit 4.
Interventions
In total 4 protein products will be tested containing a single or mixture of plant and dairy protein sources in a randomized order
