The Vit D Council recommends a level of 50ng/ml (125nmol/L), the Vit D Society and Grassroots Health recommends a level of 40-60ng/ml (100-150nmol/L), therefore your Vit D level is perfect.
You’re getting the right amount of vitamin D by the standards set by the Vitamin D Council and Endocrine Society. The Institute of Medicine, however, doesn’t feel there is enough evidence to say that having a level higher than 50 ng/ml is of any benefit.
Some vitamin D researchers believe that these levels are the best to aim for, though more research is needed to be sure about this.
Research has demonstrated many health benefits of higher vitamin D levels. What do scientists say is the target amount? 48 world-wide vitamin D researchers agree it is 40-60 ng/ml (100-150 nmol/L).

B12. 405.0 pg/ml
According to an extract from the book, "Could it be B12?" by Sally M. Pacholok:
"We believe that the 'normal' serum B12 threshold needs to be raised from 200 pg/ml to at least 450 pg/ml because deficiencies begin to appear in the cerebrospinal fluid below 550".
"For brain and nervous system health and prevention of disease in older adults, serum B12 levels should be maintained near or above 1000 pg/ml."
You really need Folate testing too as B12 and Folate work together.
You can help raise your B12 level with a good quality B Complex containing methylcobalamin and methylfolate. Often recommended here are Thorne Basic B or Igennus Super B. You can also look at a good quality whole food B Complex but ensure there is enough B12, not less than 400mcg methylcobalamin to raise your level.
When supplementing we should monitor our levels so retest after about 3-4 months. If your folate and B12 are at good levels, you can then lower your dose to maintain those levels, maybe just supplementing 2 or 3 days a week rather than 7 days a week. B12 stores are supposed to be good for 2 years, so if your level reaches the top of the range, you could swap to a B Complex with a low amount of B12.
When supplementing with a B Complex containing Biotin, or Biotin as a stand-alone supplement, this should be left off for 7 days before any blood test as it can give false results if Biotin is used in the testing procedure (which most labs do).
