You can see some people mourning their previous selves, Thiara says
Abnormal (dysbiotic) gut microbiota could account for leaky gut and inflammation in older adults (3, 9), since dysbiotic microbiota can produce metabolites that interact with the hosts intestinal epithelial cells to reduce epithelial barrier proteins like zonulin-1 ( Zo1 ), occludin ( Ocln ), and claudins, resulting in disrupted cell-to-cell connections, which compromises intestinal permeability (10, 11)
While early results are promising, many studies are either small, in-vitro, or not rigorously controlled
Exendin is only 55% similar to human GLP-1
This happens because activating melanocyte receptors (MC1) stimulates melanin production
