Please get your B12 checked before taking any. Taking it skews the result. This is according to my neurologist, who’s ordered thatvI take 1000 mcg daily with sublingual tablets. My body doesn’t absorb it well, so it’s sublingual or injections. I’ve done both. I’ll take it indefinitely according to my neurologist. It takes a long time to restore the body.

I have hypothyroidism, take medication and have my thyroid level checked regularly. It’s been ok for many years with meds, but I will mention it again when I see the rheumatologist next week. Thanks for the info. I also had constipation, but that has cleared since I started B12 treatment.
