Figure 4: The ‘leucine trigger’ concept with data adapted from (Tang et al.,
2009) as shown for whey protein, soy protein, and casein proteins. These
proteins would be digested in the following order: whey ≥ soy >> casein, and
the following leucine content: whey > casein > soy. Thus, a greater and more
rapid rise in blood leucine triggers a greater rise in MPS.
