I'm a 61 year old male who has had symptoms consistent with PA most of my life. Although I feel like crap most of the time, I have managed to keep fit/exercise frequently and eat a "whole foods" (lower case!) diet. BMI is about 22. I've been investigating PA as a source of my issues since 4/2019, when I began taking 2000 mcg Cyanocobalamin orally daily until 6/2019, when I began Cyanocobalamin injections, 1000 mcg 3 x week. I have noted some improvements, though they haven't been massive. Here are my pertinent test results, any insights are greatly appreciated!
Note that I'm not sure if the 1st 2 tests were ELISA.
