Vitamin D supplementation may help to prevent a range of viral and bacterial infections
New research published today indicates that taking a regular vitamin D supplement will reduce the chance of picking up infections
BBC health report on this research:

Everyone should consider taking vitamin D supplements in autumn and winter, public health advice in England and Wales says.
It comes as a government commissioned report sets the recommended levels at 10 micrograms of the vitamin a day.
But officials are concerned this may not be achievable through diet alone, particularly when sunlight, which helps in vitamin D production, is scarce.
Low vitamin D levels can lead to brittle bones and rickets in children.
Dr Charles Shepherd comments:
We often flag up the fact that people with ME/CFS, especially those who are partially or totally housebound, are at increased risk of developing vitamin D deficiency - mainly due to the lack of exposure to sunlight (which helps with vitamin D production) but this may also be compounded due to lack of foods that are good sources of vitamin D in their diet (i.e. oily fish, eggs, fortified breakfast cereals).
This new advice from Public Health England, which recommends that everyone should consider taking a vitamin D supplement during the autumn and winter months, is therefore very relevant - because vitamin D is essential for good muscle and bone health. So any deficiency of vitamin D in ME/CFS could add to the problems of muscle weakness that is already occurring.
On a personal basis, I will now be following this advice and taking a vitamin D supplement during the autumn and winter months.

All aspects of vitamin D, and vitamin D deficiency, are covered in the MEA information leaflet on vitamin D:

Summary of key points relating to the vitamin D (25-hydroxyvitamin D) blood test:
The National Osteoporosis society (NOS) guidelines (UK, 2013) and the Institute of Medicine (US) classify vitamin D results as follows:
High levels of 25- hydroxyvitamin D usually reflect excess supplementation from vitamin pills or other nutritional supplements.

Summary of research into vitamin D and ME/CFS from the MEA purple book (2016 edition):
Consider vitamin D deficiency in adults with restrictive diets and lack of access to sunlight. A retrospective study of serum 25-OH (hydroxy) vitamin D levels in 221 ME/CFS patients found moderate to severe suboptimal levels, with a mean level of 44.4nmol/l (Berkovitz et al 2009).
Vitamin D deficiency often goes unrecognised and can cause bone or muscle pain and muscle weakness. It can co-exist with ME/CFS.
Levels < 25nmol/ml may be associated with symptoms.
NB: Low serum calcium and phosphate and an elevated alkaline phosphatase are consistent with osteomalacia.

The National Osteoporosis society (NOS) guidelines (UK, 2013) and the Institute of Medicine (US) classify vitamin D results as follows:
- 25-hydroxyvitamin D of less than 30 nmol/L is deficient
- 25-hydroxyvitamin D of 30-50 nmol/L may be inadequate in some people
- 25-hydroxyvitamin D of greater than 50 nmol/L is sufficient for almost the whole population.
High levels of 25- hydroxyvitamin D usually reflect excess supplementation from vitamin pills or other nutritional supplements.
