It's not unusual for vegetarians to be low in vitamin B12, and
deficiency can cause the symptoms you describe. I'm not saying that this is necessarily causing your symptoms, but it's a possibility, and one that is easily remedied. Taking a typical B12 supplement (cyanocobalamin) may not work for individuals that have the
MTHFR mutation, but another form—
methylcobalamin—should. Have you had your B12 levels checked lately? A minimum of 400 is recommended, regardless of what the labs might say.
