Hi all, seems like there have been some B12 related questions in this forum with good answers so I really hope to find here someone who had experienced it, or has some experience with it at least.

Im a 22 years old male. For about a year i have experienced weird visual problems, chronic fatigue and memory problems, with no doctor finding any reason for them. B12 deficiency runs in my family, in form of Hashimoto / pernicious anemia.
I got my B12 levels tested in march, with a result of 270 pg/mL. I got them tested in june again with a result of 239 pg/mL. Doc said this is the normal range and should not cause any problems.
Can he be wrong? There is any chance for B12 to be the cause? Have some of you experienced something similar?

Thanks everyone for reading!
