Hi,
I've been suffering symptoms such as short term memory loss, confusion, obsessive thoughts, anxiety, heart palpitations, irritability, extreme fatigue, low motivation, etc.
My B12 level range came back as 509 or 512, I don't remember which but it was one of them two numbers. I live in Europe and found out that at this range people can experience numerous psychiatric and physical symptoms. Has anybody else experienced symptoms at that kind of range?
