Vit D

Sleepyachy profile image

Hi again , my last bloods my vit d was up to level . Should I stop taking the 2000iu now? I was feeling better , could notice difference. But last few days feeling crappy , hard to get out of bed etc. Then I thought vit D can be bad if over level and too high. Any advice please

Your result on 15th May was 78.2nmol/L - is that what you consider "up to level"? It puts you in the "Sufficiency" or "Adequate" category.

The Vit D Society and Grassroots Health recommend a level of 100-150nmol/L.

The NHS lab which does private Vit D testing for the public gives the "Adequate" category a range of 50.1-220 and over 220nmol/L they say is risk of toxicity.

So, no, you don't stop your 2,000iu D3 daily at the moment, if that was my result I'd continue until I was in the 100-150nmol/L range, preferably 150, then I'd find my maintenance dose by trial and error.

Awe thank you so much Seaside Susie .You found my latest results faster than I could. Awe thanks I will carry on taking then. I just started getting paranoid thinking it was going too high. Only started taking 20th May and I definitely thought I could tell a difference but this last few days just on go slow mode. Might be with the warm weather. I think I prob have another blood test when I've taken all the ferrous sulfate .By looks of it got couple more months on them . Hope your well

🤗 thanks again for your advice x

Just re read that and abit confusing , I haven't only just started taking vit d . I'm on about ferrous sulfate thenx
