Does anyone know why standard blood tests come back >above high reference for Folate? I was very low 4 months ago but the last 2 tests have shown >above high reference 25, yet i have not been supplementing Folate. Levels of Serum B12 have been steadily dropping and the last test was 500 but i was symptomatic of low B12, iron and Vit D so suspect that it wasn't getting to the cells). I have been low in ferritin, deficient in Vit D (I have been supplementing Vit D3, Vit K2, Magnesium Glycinate, Liquid iron and Oral Spray Vit B12,).
If you supplement with B12, how can you tell when you have got levels to a reasonable level? Cannot find how to do this - only that it stays in the system for 4 months so B12 testing will not show accurate measures.
