Guest blog - Vitamin D and Immunity by Naturopath Belinda Kirkpatrick

I think that nearly everyone must be aware of what a big Vitamin D fan I am but I just can't resist sharing the latest research with you! Testing your vitamin D is easy with a simple blood test that I can refer you for from the clinic- this is important for us all - especially women who are pregnant, doing preconception care, undergoing IVF or ART treatment and also babies and the elderly.

Vitamin D is essential for 'switching on' the immune system to fight invading pathogens.
•    In latest news, severe vitamin D deficiency (which I see every day in clinic!) has been linked to worse outcomes in pneumonia patients. 
•    Low vitamin D levels at birth appears to increase the risk of developing lower respiratory infections and wheezing in infancy and early childhood.
•    Evidence also shows that vitamin D3 may be up to 800% more effective in preventing the flu than vaccinations!

Maintaining your vitamin D levels can be assisted by consuming foods including:
•    Sardines
•    Organic egg yolk
•    Organic butter
•    Moderate amounts of full-fat dairy products

Birmingham UK NHS path lab offer postal 25(OH)D tests.
City Assays Vitamin D Blood Spot Test
Single test £25 UK but if you share a 10 pack with friends/family/online buddies you Save £5 each. They are easy to post in Large Letter.
While food sources are always useful we have to bear in mind skin creates 10~20,000iu if you lay naked at noon, 20~30mins, providing skin doesn't burn & you've not been cholesterol lowering (7 dehydrocholesterol is the precurson molecule that UVB acts on to create Cholecalciferol (vit d3))and you don't live in a city or near a motorway (urban pollution blocks UVB). So at the very best food sources can provide only 10% of our daily needs. The RDA for vitamin D is only sufficient to prevent rickets.
If we want to benefit from the full anti inflammatory action of D3 we have to keep 25(OH)D levels around 125nmol/l or 50ng/ml. If we think human milk should be a complete vitamin D replete food for human babies then 150nmol/l 60ng/ml is the target. If you are fighting cancer and want to ensure there is always a sufficient reserve of Vit d then maybe levels around 200nmol/l or 80ng/ml would be best.
To reach the first of those thresholds generally takes 1000iu/daily vitamin D3 for each 25lbs you weigh. 5000iu/drops or gelcaps are available in the UK but probably cheaper from the online USA discount providers.
