Consequently, drug delivery limitations significantly hinder clinical progress (16), and enhancing the stability of these bioactive agents within food matrices and during their passage through the GIT remains a critical challenge (12)
Supplementing with topical GHK-Cu can help restore some of these lost protective functions by delivering copper ions directly to the scalp, where they serve as essential cofactors for enzymes involved in tissue repair and hair follicle maintenance
