Hi I wish I could help you but I've no idea I've put some blood results on here myself like you I'm hoping someone will reply good luck I'm checking some of my results against others to try and get an idea but haven't got a clue


Debs_69 Your ferritin isn't quite good enough, it should be half way through range. You could give that a bit of a boost by eating iron rich foods, liver being a good one.

Vit D is way too low, the recommended level is 100-150. You should supplement with D3. I'd suggest 5000iu daily for 3 months and then retest. You can get that done through City Assays, fingerprick blood spot test costing £28, if there's nothing else you're having tested with BH.

When taking D3 we need K2-MK7. Vit D aids absorption of calcium and K2 directs the calcium to bones and teeth rather than arteries and soft tissues. Magnesium is another co-factor when taking D3.

B12 is worrying. As it is below range I would discuss this with your GP and see if he will carry out further tests. Don't supplement at the moment, once you do further results are skewed and it really needs investigating.

Folate is a bit low, it needs to be half way through range which is about 26. A good B Complex is needed that contains methylfolate. Thorne Basic B or Jarrows B Right are good ones. However, as this is usually taken alongside B12, again I would hold off until your B12 has been looked into as some B Complex supplements contain B12.

Your thyroid tests show that your conversion could be better, but that has been discussed in a previous post so I won't repeat the advice given there.


B12 and D are shockingly low, which could give hypo-type symptoms. Conversion to T3 isn't great either, but might improve with better B12 and D.
