Did you know that before the year 2000, most doctors believed that none of their patients could be vitamin D deficient? But as technology to measure for vitamin D became affordable, more studies were conducted. According to Dr. Michael Holick, who is one of the leading vitamin D researchers, The Centers for Disease Control and Prevention (CDC) reported that 32% of adults and children in the US were vitamin D deficient. That’s a pretty high number; so for that reason alone, it’s important that you look for signs of vitamin D deficiency.
With more research being conducted, Holick believes that about 50% of the general population may be at risk of vitamin D deficiency.
The only way to know for sure if you are vitamin D deficient is by a blood test. But the signs and symptoms that come along with this deficiency could be helpful as well. If any of the following signs apply to you, it might be a good idea to go see your doctor and have your blood checked, because you might be vitamin D deficient.
- Holick explains that if you have darker skin, you may need as much as 10 times more sun exposure to get the same amount of vitamin D as an individual with pale skin.
- He adds that your skin pigment acts as a natural sunscreen, so the more pigment you have, the more time you need to spend in the sun.
YOU HAVE THE BLUES:
- According to a study published in The American Journal of Geriatric Psychiatry, one of the signs of vitamin D deficiency is having a low mood.
- To prove this theory, researchers studied 80 elderly patients and they found that those who had the lowest vitamin D levels were 11 times more likely to be depressed than those who had healthy levels of vitamin D.
YOU’RE AT LEAST 50:
- According to the International Society for Clinical Densitometry, about 95% of senior citizens may be vitamin D deficient.
- The reason is not just because they spend a lot of their times indoors; another reason is that they produce less when they’re exposed to the sun.
- They add that an elderly individual over the age of 70 produces 30% less vitamin D than a younger person with the same sun exposure.
