Vitamin D confusion

November 22, 2018 at 9:06 pm

There has always been confusion about vitamin D.

There is no consensus about what constitutes normal blood levels and the information about the need for supplements varies.

Despite this, large sums of money are spent carrying out blood tests for vitamin D levels, and buying vitamin D supplements.

Recent studies have shown that Vitamin D supplements do not prevent bone fractures and do not reduce the likelihood of cancer or heart disease. High vitamin D levels, however, have been associated with some forms of cancer (skin prostate and blood).

Vitamin D levels can be boosted sufficiently by exposing a few inches of skin for several minutes three times per week during the summer. In winter, 1000IU Vitamin D per day is sufficient.


Over 10,000 cases of skin cancer per year in Scotland. Don't become a number.

I had just been told after attending the Mole Clinic at my local pharmacy that I could potentially have a melanoma on my right leg. Obviously I was very worried and upset by this and when I met Dr. Herd he did his best to try and reassure me. The mole was removed and after a few anxious weeks my results came back fine. I have since seen Dr. Herd on a regular basis over the years for annual skin check ups and I find that his calming and friendly manner gives me peace of mind.
