I would show them to your GP and see what s/he intends to do.

Folate is deficient. My GP prescribed 5mg folic acid for a couple of months to correct folate deficiency.

B12 is very low. I would ask your GP to check intrinsic factor antibodies to rule out pernicious anaemia causing low B12. are the experts re folate deficiency, low B12 and pernicious anaemia.

Ferritin is deficient which can indicate iron deficiency anaemia. Ask your GP to do an iron panel and full blood count to confirm or rule out anaemia.

Vitamin D is severely deficient. My GP prescribed 40,000iu ProD3 daily x 14 as loading doses followed by 2,000iu daily x 8 weeks to raise my vitD from <10 to 107.
