Once bound to GLP-1R, GLP-1 initiates a cascade of events, including the activation of membrane-bound adenylyl cyclase (AC) leading to cyclic adenosine monophosphate (cAMP) synthesis
Myth: pyridoxine makes semaglutide work better for weight loss Pyridoxine does not enhance the weight loss mechanism of semaglutide
Epidemiology: High levels of vitamin B12 were found in: Causes: Excessive supplementation (a direct increase in plasma vitamin B12 by excess intake or administration) Increased release of vitamin B12 from tissue stores (liberation from an internal reservoir): Solid tumors (especially hepatic or hematologic malignancies) Liver metastases Increased binding proteins: 7 Excess production: Liver disease (e.g., hepatitis, cirrhosis, hepatocellular carcinoma) damaged hepatocytes release haptocorrin (transcobalamin I) and B12 into circulation Myeloproliferative disorders these increase granulocyte production, which leads to more haptocorrin (transcobalamin I/III), a B12-binding protein produced by proliferating myeloid cells
Enhanced insulin secretion : GIP and GLP-1 stimulate insulin release through partially distinct intracellular mechanisms
So, while dietary glutathione is helpful (especially for gut health, where it can act locally), its not a reliable way to increase intracellular glutathione levels throughout the rest of your body
