Comprehensive assessment of post-prandial protein handling by the application of intrinsically labelled in vivo in humans.
There are many advantages of this method.
Building amino acid tracers into dietary protein allows assessment of protein digestion and absorption into the circulation. This is preferred over plasma amino acid concentrations that are just a proxy.

Note that this was a methodological review and does not have many practical applications for those who want to optimize protein synthesis. For more practical advice, see our comprehensive blog article The Ultimate Guide to Muscle Protein Synthesis, or our scientific review (1).
All living tissues are constantly renewed in a process called protein turnover, which allows a high tissue quality to be maintained. For example, muscle tissue has a protein turnover rate of 1-2 % per day, which translates to muscle tissue being completely renewed every 2-3 months.

Protein ingestion stimulates muscle protein synthesis, the process driving muscle adaptation and growth (1, 2).
Most protein is consumed during the 3 main meals: breakfast, lunch, and dinner (3). This leaves a long overnight period where little dietary protein is available for muscle recovery. Can an extra protein meal/supplement prior to sleep be beneficial?
Our work shows that an extra protein supplement before sleep improves overnight muscle protein synthesis. We have shown this in healthy younger and older subjects (4, 5).
Casein Ingestion Does Not Increase Muscle Connective Tissue Protein Synthesis Rates
A single session of resistance exercise stimulates muscle protein synthesis. Over time, resistance training can result in muscle mass gains.
Protein intake also stimulates muscle protein synthesis (Trommelen, 2020). Therefore, protein intake can further improve training-induced muscle mass gains.

Milk contains both whey and micellar casein protein (~20 and 80 % of total protein content, respectively). Whey is a fast digesting protein. In contrast, micellar casein is a slow digesting protein (Gorissen et al, 2020).
Micellar casein clots in the stomach due to the acidic environment and the presence of pepsin. However, the micellar casein structure can also be intentionally disrupted by various food processing techniques, resulting in food products such as cheese and yoghurt.
