Vitamin D

Vitamin D is a fat soluble vitamin and therefore requires fat for absorption. It is estimated that over 70% of the US population is deficient. It is an important vitamin as every cell in the body contains vitamin D receptors. Two commonly known known functions of Vitamin D includes maintaining calcium levels and supporting cardiovascular health. Low vitamin D levels have been associated with many chronic diseases including many cancers, heart disease, osteoporosis, type 2 diabetes and autoimmune diseases. Everyone should have their vitamin D level checked by their doctor to see if they are deficient. The correct test is a 25-hydroxyvitamin D level. It should be at least 35ng/mL with optimum levels above 50ng/mL. People who are deficient can increase their levels naturally  by exposure to the sun.  Vitamin D can also be obtained in fortified foods including fortified plant milks (such as almond milk or soy milk) and cow’s milk. Vitamin D supplements are also available – talk to your doctor to see if this is necessary and before starting any supplement.
