It helps protect the skin from oxidative stress caused by free radicals, promoting a healthier and more youthful appearance. In the medical field, it is studied for its potential role in wound healing and tissue repair, as it may enhance cell regeneration and reduce inflammation. Additionally, Gly-His is utilized in research for its metal-chelating abilities, which are valuable in studying biochemical processes involving metal ions. Its applications also extend to the food industry, where it is explored as a natural preservative to extend shelf life by inhibiting oxidation.
