Oliver Gillie, in Memorandum

This website was established over a decade ago in collaboration with Oliver Gillie, one of the first and strongest advocates of Vitamin D. Oliver sadly passed away May 2021 at the age of 83. Gillie held a doctorate in genetics from Edinburgh University before embarking on his medical journalistic career that lasted over more than 40 years. Early on his career he became fascinated with the role and Vitamin D and the consequences of deficiency.  He was responsible for describing the “Scottish Effect” arguing that many of the health problems in Scotland were a result of the constant cloud cover which prevents the production of Vitamin D.  Today, thanks largely to Gillie’s work, the Scottish government recommends that everyone, including children, should take Vitamin D supplements, especially during the low-sunlight months from October to March.  We are glad to continue the work that he was so pivotal in starting.

Personal stories

  • William B Grant, PhD

    Californian scientist who has published more than 170 scientific articles about Vitamin D

    “My studies have found that people with low levels of vitamin D are more likely to get any of approximately 100 common diseases including autoimmune diseases, many types of cancer, heart disease, dementia, and infectious diseases. I take 4000 IU of vitamin D a day to maintain my blood level above 150 nmol/l (60 ng/ml) and get some mid-day sun which is limited in San Francisco due to the frequent clouds and fog.”

  • Graeme Peacock

    An energetic retiree living in Yorkshire. Has had diabetes for 15 years

    “My GP was sceptical when I told him I wanted to take vitamin D. My blood glucose was then 10.5. I took 2000 IU vitamin D a day and felt a lot better. My blood sugar gradually came down and after 18 months it was 6.5. Now my GP even suggests vitamin D for other patients.”

  • Judy Graham

    Editor of New Pathways magazine, published by the Multiple Sclerosis Resource Centre. She has also written ‘Managing Multiple Sclerosis Naturally – A Self-Help Guide To Living With MS’

    “For the last five years or so, I have been taking 5000 IU of vitamin D a day to help control my MS."

  • Sheree Bryant

    Health charity campaigner

    "It came as a shock to me to realise that people with brown skin living in Europe were invariably badly deficient in vitamin D. I did lots of research on the issue and now my family (pictured) takes a supplement all year round. My son is a competitive athlete and it has been specially important for him."

  • Dr Helga Rhein

    Edinburgh GP, Vitamin D pioneer

    “We get very few days when it's warm enough to be out of doors with short sleeves in Scotland and I find that many of my patients are deficient in vitamin D. I regularly recommend patients to take a vitamin D supplement and also prescribe it for many.”
