Time course of postprandial plasma concentrations of individual essential amino acids from baseline up to 4 h postadministration (means ± SEMs, n = 12–13); (A) Ile, (B) Leu, (C) Val, (D) Arg, (E) His, (F) Lys (G), Met (H), Phe (I), Thr, (J) Trp; significant effect of time postadministration in all parameters (P < 0.01); significant effect of treatment (P < 0.05) for Val, Arg, His, Met, Trp, Phe. ^#significant difference between NWPI and DWPI; ^*significant difference between PBI and NWPI (treatment × time, P < 0.05); ^†significant difference between PBI and DWPI (treatment × time, P < 0.05). PBI, protein-based ingredient; NWPI, native whey protein isolate; DWPI, denatured whey protein isolate
