Hi Ted,

Sorry to trouble you, but I was hoping you could answer a question.

I live in the UK like yourself, and have been taking 5000iu Vitamin D3 now for almost a year.

I have never been tested, and I'm not sure my GP will test me for Vitamin D without good reason.

Can you recommend any genuine, safe and reliable home tests or retailers where I can provide a sample for testing?

I can see from previous posts that you mentioned Grassroots, however they appear to require $60 every six months for the test kit, which is a little more than I can afford.

Thanks in advance.

Tony
