Vitamin levels

Where should the following vitamin levels be within the ranges:

B12

Vitamin D

Ferritin

Folate

And any others that I am not aware of that are important for the thyroid.

Also, do you have to take these vitamins separately if deficient and not in multivitamin form?

Thank you

As a rough guide vits should be over half way through range and heading into top third of range. If there is no range and just a greater than sign and a number then aim to be double that number.Only take the vitamins in which you are deficient. Multivitamins tend to be poor quality and they will contain things you don't need to supplement and often iodine. Multis often contain things which shouldn't be taken together because they interfere one with the other such as vit c and b12.

What supplements were you taking when these tests were done

All look pretty good

A daily vitamin B complex

Vitamin D

and increase iron rich foods in your diet to improve ferritin levels

Thank you for your reply. I only take vitamin D at the moment and primrose oil. Do I need more vitamin D if it is at adequate levels? I don’t eat red meat. Can I improve ferritin levels by other dietary forms?

Also, can I ask why I would need a vitamin B complex when it is halfway through the range?

Thank you
