Many people, especially vegans, don't get enough vitamin D. So much so that it is now recognised that everyone living in the far Northern (and Southern) hemisphere, where the angle of the sun in the winter is insufficient to make much vitamin D, and the cold climate not conducive to exposing naked skin to sunlight, need to supplement this versatile vitamin.
If you live in sunnier climates and spend lots of time outdoors, you may just make enough from the synthesis of vitamin D, acting on cholesterol in the skin. Vitamin D also stores so if you spend a couple of weeks in the sun in the winter months that too might see you through.
Due to these variables, it is ideal to know your vitamin D status by measuring your blood level of 25-hydroxyvitamin D. The level you’re shooting for is 75 nmol/l. Below 50nmol/l is considered inadequate. Fortunately, this is one inexpensive test many GPs are willing to give you. If not, you can get relatively inexpensive home test kits (£29) online from http://ow.ly/xgke50FoSd3. If your level is low it’s best to supplement 25mcg a day (1,000ius) and recheck that you’ve achieved a level of 75nmol/l or more.
