Summary
A Reddit user reported that a nurse gave them a methylated B12 injection, which caused over-methylation with a racing heart and anxiety and messed them up for weeks. They said they do not have the MTHFR variant and that other B12 shots had been fine. They advised others to find out which form of B12 they need before getting it.
