Ive previously reviewed the GLP-1 family of peptides extensively (here and here) and it seems every week there is a new potential use case, such as we recently saw for migraine and the oneAlzheimers disease that we await with a very high level of anticipation in September from the 2 large trials with semaglutide
Whilst vitamin B12 toxicity is exceptionally rare due to its water-soluble nature, very high levelsparticularly from mega-dose supplements or frequent injectionshave been associated with certain adverse effects, most notably skin reactions

Why B12 Matters: Vitamin B12 is essential for: Red blood cell production DNA synthesis Nerve function Mental clarity Energy metabolism Its especially critical for vegetarians, vegans, older adults, or those with conditions like pernicious anemia or digestive malabsorption issues (e.g., celiac, Crohns, or low stomach acid)
