Jimmy that's good info. Unfortunately my GP doesn't seem to find my Vit D status worrisome, although I do, and I'm scared of jeopardising the new patient/doctor communications as my last GP (had for 8 years) ended up thinking I was a nutter because I asked too much about hughes and lupus. With good reason, but that's another story.
I'll ask my pharmacist instead, he's amenable to questions! Maybe we have a similar high-dose D3 in Ireland. At the moment I'm taking 40 xdrops of D3, it's actually a product designed for babies (2 drops a day) so it takes time to get them all in!!
And high-dose D3 would be cheaper too. Will ask him next week.
Just wondering what did you do for cal/mag/zinc/copper while you took 50,000 IU? - At the moment I'm taking 1500mg cal/1000mg mag/35mg zinc/2mg copper along with 4,000IU D3.
p.s. I think you should call yourself jimmyvits by the way! You are a font of knowledge.
