Where it works: Adipose tissue (fat cells): Reduces inflammation and may improve fat metabolism Pancreas: Works alongside GLP-1 to enhance insulin secretion Brain: May contribute to appetite regulation (research ongoing) Weight loss contribution: When GIP is added to GLP-1 (as in tirzepatide), weight loss increases from ~15% to ~22%
Conversely, lactylation of lysine-specific demethylase 1 (LSD1) in melanoma promotes its interaction with Fos-like antigen 1 (FosL1), resulting in repression of TFRC-mediated iron uptake and conferring resistance to ferroptosis (70)
People with compromised immune systems : Conditions like HIV, cancer treatments, or other immune system disorders can result in reduced glutathione levels, impacting the bodys ability to fight infections and heal
Limitations include limited large-scale human clinical evidence, challenges in extrapolating in-vitro concentrations to in-vivo contexts, stability sensitivities (light, heat, alkaline pH), and variability in supplier purity
