What is Vitamin D and why is it so important?

How to Restore Low Levels of Vitamin D

If you suspect that you might be low on vitamin D, report this problem to your doctor: a simple blood test will answer the question as to whether or not a deficiency is causing the problem.  And the good news is that there are plenty of simple lifestyle changes you can make that can help you raise your low vitamin levels, including:

• Eating foods that are rich in vitamin D, either because they contain it naturally or they have been fortified. These include egg yolks, fatty fish like salmon and tuna, beef liver or some cheeses. Fortified dairy, cereals, juices or other fortified plant-based drinks (such almond milk).
