When it comes to the functioning of your cells, methyl groups are used in methylation reactions.[ref] Examples of methylation reactions include: synthesis of some of the nucleic acid (DNA) bases turning off genes so that they arent transcribed (DNA methylation) converting serotonin into melatonin methylating arsenic so that it can be excreted breaking down neurotransmitters metabolizing estrogen regenerating methionine from homocysteine Methylation in the right amount: For example, you need enough folate (vitamin B9) and methylcobalamin (vitamin B12) for the methionine synthase reaction to occur
Seek urgent help if: Youre soaking through a pad or tampon every hour for more than 2 hours Youre passing clots larger than a golf ball Youre feeling dizzy and faint
[104] [105] Deficiency does not develop if dietary intake of vitamin B 12 is adequate or prophylactic B 12 supplementation is given
Chloramphenicol should be discontinued if anemia attributable to chloramphenicol is noted during periodic blood studies, which should be done approximately every 2 days during chloramphenicol receipt
To Summarize Vitamin B12 injections side effects are incredibly rare, and when reactions occur, they are more likely due to additives rather than the B12 itself
Patience and consistency are key
