For this specific question, I would recommend: reviewing the relevant clinical guidelines.

Shop Reference StandardsWant to share my personal experience related to Vitamin B12 monitoring anyone since I think it might help others in a similar situation.
I started my GLP-1 journey in March 2025 at 252 lbs with metabolic syndrome. My telehealth provider prescribed semaglutide 0.25mg to start.
Now, 14 months later: I am down 62 lbs, my labs have normalized, and my sleep apnea has improved dramatically. The Vitamin B12 aspect specifically was something that made a big difference in my journey.
This forum was my go-to resource throughout.
Just wanted to say — for anyone reading this Vitamin B12 thread who is feeling discouraged: it gets better. The first 6 weeks are the hardest. Hang in there. 💪
