Secondary

MeasureTime frame

The amount of changes of stool frequency, stool volume, stool days, stool shape, stool smell, exhilarating feeling between before test-food consumption and one and two weeks after the start of test-food consumption 2. AUC, Cmax, Tmax, and the measured values at each assessment point* of total amino acid amount 3. AUC, Cmax, Tmax, and the measured values at each assessment point* of taurine, phosphoethanolamine, aspartic acid, hydroxyproline, threonine, serine, asparagine, glutamic acid, glutamine, sarcosine, alpha-aminoadipic acid, proline, glycine, alanine, citrulline, alpha-amino-n-butyric acid, valine, cystine, methionine, cystathionine, isoleucine, leucine, tyrosine, beta-alanine, phenylalanine, beta-aminoisobutyric acid, homocysteine, gamma-aminobutyric acid, monoethanolamine, hydroxylysine, ornithine, 1-methylhistidine, histidine, lysine, 3-methylhistidine, tryptophan, anserine, carnosine, arginine, alloisoleucine, Fischer ratio (BCAA/AAA) *Each assessment point indicates before test-food consumption at 30, 45, 60, 90, 120 and 180 minutes after test-food consumption
