Simple vitamin D home-testing kit
Public Health England estimates that 10 million people in the UK may be deficient in vitamin D. But the only way to know if you are is via a blood test. Betteryou has teamed up with an NHS trust to offer a home test kit (£28, betteryou.com). Just collect a drop of blood using the fingertip lancet and post it in the envelope provided. Our tester received her test results and advice in five days.
