I have just read the following re Vitamin D - two excerpts:-
"The findings carried out by University Hospital Zurich in Switzerland mirror the UK Department of Health guidelines, which deem those over the age of 65 as an ‘at risk group’ for vitamin D deficiency, and recommends regular supplementation
and
Diseases related to Vitamin D deficiency, including Multiple Sclerosis, Type 2 Diabetes, bone diseases such as osteoporosis and a growing number of internal cancers are believed to cost the UK taxpayer £29 billion annually – more than a quarter of the NHS budget.."
How many people over 65 get Vitamin D supplementation?
