They seem to work. My most recent blood test, in November, showed a Vitamin D3 content of 201 nmol/L. Barts recommend a reading of over 100 but less than 250.
I was in Holland and Barrett today looking for some vitamin D to help me cope with a current relapse and I found BetterYou Dlux3000 vitamin D spray.
It has the advantage of getting it directly into the bloodstream. The lady that sold it to me said I could take multiple sprays in one day when i explained about my MS.
The packet says 3000 IU 75ug.
I presume this means that each spray contains 3000 IU of vit D? The woman said there’s no problem for me to take 3/4 sprays a day. Presumably that would give me 9000/12000 IUs of Vit D. Is that right?
