Discussion This study demonstrates that increasing milk intake to the recommended 3 cups/day in older adults with habitual low intake raised brain GSH concentration over 3 months

Instead of forcing rapid hormonal changes, many peptides work by supporting natural signaling pathways, such as growth hormone release, tissue repair, or metabolic regulation
