It also enhances elasticity by promoting elastin production, leading to a smoother, firmer skin surface
John Buse, Director of the Diabetes Care Center at the University of North Carolina and a principal investigator in GLP-1 outcomes trials, has noted in published commentary that "the antioxidant milieu in type 2 diabetes is genuinely impaired, but whether exogenous supplementation corrects the underlying defect or simply raises circulating levels without tissue impact remains unresolved."
