A quick vitamin D primer
You walk in the sunshine every day (wearing your SPF, of course). You eat right. You get enough sleep. But you still may be missing something even if you’re doing all the right things—vitamin D. Though rare, severely low levels of vitamin D can cause rickets in children and osteomalacia (softening of the bones) in adults. Left untreated, these conditions can lead to bone pain, soft and brittle bones, and muscle pain and weakness, according to the Cleveland Clinic. But recent research has suggested a connection between even moderately low levels of vitamin D and a number of surprising health conditions, including diabetes, osteoarthritis, and cancer. Here are a few sneaky vitamin D deficiency symptoms. If you feel that you’re suffering from any of these symptoms, talk with your healthcare provider, who will likely recommend a blood test. This is really the only way to accurately determine your vitamin D level. Then you can discuss ways to boost your levels, typically by taking an over-the-counter supplement.
You’re tired all the time
If you aren’t getting enough vitamin D, you may feel completely exhausted, even if you get plenty of sleep. “There is mounting evidence that vitamin D deficiencies are associated with fatigue and sleep disorders,” says Catherine G. R. Jackson, PhD, a professor of kinesiology and exercise science at California State University in Fresno. A study in the North American Journal of Medical Sciences found that low vitamin D levels were prevalent in people who are fatigued. Taking more vitamin D helped improve their symptoms. Here are other sneaky reasons you may be tired all the time.
