Does anyone know what the optimum amount of vitamin d to supplement is? I am currently taking 400 iu.

Many thanks.

It would depend on how deficient you are. Have you had a test? If so what was the result?

I was severely deficient at 15nmol/L. I managed to get it up to 202 with high dose supplements, then reduced and now maintain around 150 on 5000iu daily Mon-Fri (weekends off). I will probably reduce my maintenance dose a bit more now we've got some sunshine.

Thank you. No not had a test for deficiency but wondered if it was safe to take more.

To put it bluntly the amount your taking isn't worth taking especially if you are paying for your own supplements.

If you are in the UK City Assays do a postal test for around £30.

Take a test and post the results. Make sure you haven't taken your supplements for 48 hours before taking the test.

Some people have fine vitamin D levels but most people in the UK don't. Telling you to take more with no test results isn't good practise.
