Metformin, commonly prescribed for type 2 diabetes, is known to reduce B12 absorption over time, as highlighted in MHRA safety updates
Of greater concern are potential risks from combination use: Hypoglycaemia risk: Retatrutide enhances insulin secretion in a glucose-dependent manner, which carries a low intrinsic hypoglycaemia risk when used alone
These include dietary calcium, ethanol, and caffeine
AOD 9604 Peptide therapy is a popular weight loss program because it can target areas in the body that store abnormally high fat levels
However, vitamin B 12 is an essential vitamin and requirements are increased during pregnancy
Nevertheless, use of metformin may decrease vitamin B 12 status: a meta-analysis of four short-term intervention trials (up to 4 months duration) in patients with type 2 diabetes found that metformin use decreased serum cobalamin concentrations by 57 pmol/L, which could have clinical implications if such patients have suboptimal vitamin B 12 status (146)
