Hello, I am new here. I have a quick question. My methylation isn't working well, after a year of active B12 supplementation (with all the other Bs) I still have my homocysteine level > 14. I seem to be stuck around that number and it doesn't want to go down. My B12 serum levels have gone from 312 to 880 micrograms/mL which is almost at the end of the range. (900 according to the lab tests) Question is, is it safe to continue the supplementation at ~1000mcg (every day)? What are the risks of going to high with the serum levels? Thanks in advance, and sorry if there's any misspelling. English is not my native language.
