Exact phrase from label:
Oral administration of glycine to rats was found to induce a significant increase in the plasma and cerebrospinal fluid glycine concentrations and a significant decrease in the core body temperature associated with an increase in cutaneous blood flow. The decline in the core body temperature might be a mechanism underlying glycine's effect on sleep, as the onset of sleep is known to involve a decrease in the core body temperature.

Biological macromolecule-based hydrogels, derived from natural proteins and polysaccharides, have emerged as promising platforms to bridge this gap due to their intrinsic bioactivity, tunable physicochemical properties, and structural similarity to the extracellular matrix (ECM). This review provides a comprehensive overview of regenerative biology inspired hydrogel systems constructed from key biological macromolecules, including gelatin methacryloyl (GelMA), hyaluronic acid, chitosan, and silk fibroin, and examines how their molecular design can be tailored to promote dynamic tissue integration and regeneration.

Low-protein diets (LPDs) and supplemented very low protein diets (sVLPDs) have been successfully employed to decrease the symptoms of people living with non-dialysis-dependent CKD, delay the progression of the disease and retard the need for dialysis.
Label source:
Expert review: High-protein supplement load can increase renal solute load and nitrogen waste production; in severely compromised kidneys, additional protein catabolites (from hydrolyzed collagen) may worsen uremic burden. For low-dose (40mg) undenatured collagen, this concern is minimal per established renal nutrition guidelines.
