Doctors know nothing about nutrients. They don't 'do' them in med school. However, not only is your B12 low enough to take supplements, it's so low that you should be tested for Pernicious Anemia. But, you might have to insist on it with your doctor. Best not to start supplementing before this has been done.
Going by those results, I take it you didn't have your antibodies tested for autoimmune thyroiditis (aka Hashi's). You should ask to have those done, too. It's important to know.

As Greygoose has said, you must get tested for B12 deficiency/pernicious anaemia. Your B12 level is below range, your GP has no reason not to investigate this further, and it's far too low to self supplement.
Check out this list of signs/symptoms of B12 deficiency
b12deficiency.info/signs-an...
and list any that you may have to discuss with your GP when requesting further testing.
Also, because B12 and folate work together, your GP should also test your folate level.
Come back and let us know the outcome.
Do not take any B12 supplements or B Complex until further testing has been carried out.
You very likely need B12 injections.
As you have such a dire B12 result, besides testing folate your GP should test Ferritin and Vit D. Plus thyroid antibodies as Greygoose has mentioned.
What dose/brand of Levo have you been given?
Hi thanks for reply I'm on 50mcg Teva
OK, so that's the normal starting dose. You should retest and have an increase of 25mcg in 6 weeks, then continue retesting/increasing every 6-8 weeks.
Teva is not tolerated by many members who seem to have adverse reactions to it. However, some do well on it and it is the only lactose free Levo tablet in the UK. See how you go.
