Brief Answer:
Yes, they are recognised side effects. They are not harmful!

Detailed Answer:
Hi and thank you so much for this query.

I am so sorry to hear about this low levels of vitamin B12. These are recognized side effects of vitamin b12. However, they are not harmful. At this time, drink as much water as possible to replace any possible fluid losses through diarrhea. Be calm and relaxed knowing this will soon fade away.

I hope this helps. I wish you well. Feel free to ask for more information and clarifications if need be. Above all, thanks for using our services.
