Hi. Has anyone with had any success improving anxiety and low mood by increasing B12 / folate and Ferritin levels? My 18 year old daughter suffers from anxiety and low mood and recently had blood tests with the following results: B12 - 235 pmol / Folate - 7.3 mol / Ferritin 38 ug/l all of which I believe are on the lower end of the accepted range. Thanks
