Vitamin D - the sunshine vitamin and your immune system

Vitamin D has been in the press a lot. Partly because Osteoporosis is on the rise. Vitamin D plays a role in Osteoporosis because of its interplay with calcium. calcium is essential for bone health, however, you must have adequate vitamin D levels to absorb the calcium. Therefore GP's now prescribe  Vitamin D. 

Vitamin D is a crucial factor in promoting a good immune system. Vitamin D makes macrophages, one  type of white blood cell that digest viruses or bacteria that enter your body. 

How do you feel if you are low in vitamin D?

  • Low immunity  - you either get alot of coughs and colds or you find it difficult to shift a virus
  • Insomnia
  • Nervousness and anxiety

The demand for vitamin D increases in a variety of ways, for example, if you you drink alcohol, are a diabetic, a vegetarian, have crohn's disease or treating cancer.

What do I need to eat to get more of it?

This is the tricky part. Yes, there are traces of vitamin D in some foods like egg yolk and sprouted seeds but not enough for your daily requirements. You need the sun. Sunshine on your skin gets made into vItamin D in your body. This is hard to obtain during the long UK winters, that's why supplementation is recommended from October-April. However, It is very important to get your vitamin D levels checked by your doctor before supplementing.
