Do You Have Enough Vitamin D?

Vitamin D is one of the most interesting vitamins in this world.  It is essential for the human body to function properly but at the same time, it is only found in salmon, mackerel, tuna, and foods that are “fortified” like dairy products or juices.  So if vitamin D is not found regularly in the foods we eat, how do we acquire it?

Vitamin D is synthesized through our skin upon exposure to the sun.  It is recommended that we expose our face, hands, arms, and legs three times a week for 5-10 minutes with no sunscreen.  Unfortunately, this is not always possible due to where we live, and what time of year it is, so supplementation becomes important.  Most doctors recommend 400-1000IU per day, the older you are, the more units you need.  Your doctor can check vitamin D levels through a simple blood test.  If your levels are exceptionally low you may notice some subtle symptoms such as fatigue, muscle weakness, diminished cardio or aerobic ability, increased sensitivity to pain, irritability, or high blood pressure.  Have you been diagnosed with repeated stress fractures?  This could be another sign you need to increase your vitamin D intake.  You should always check with your doctor before taking any supplements, especially if you suffer from atherosclerosis, kidney disease, sarcoidosis, or hyperthyroidism since vitamin D increases calcium levels.
