Vitamin D is an extremely important vitamin that has powerful effects on several-systems throughout the body. Unlike most vitamins, vitamin-D actually functions like a hormone, and every single cell in your body has a receptor for it. Your body makes it from cholesterol when your skin is exposed to sunlight. It’s also found in certain foods such as fatty fish and fortified dairy products, although it’s very difficult to get enough from diet alone.
The recommended daily intake is usually around 400-800 IU, but many experts say you should get even more than that.
Vitamin-D deficiency is very common. It’s estimated that about 1 billion people worldwide have low levels of the vitamin in their blood.
Here are 6 signs you may have Vitamin-D deficiency.
1.Bone and Back Pain
Vitamin-D is involved in maintaining bone health through a number of mechanisms.
For one, it improves your body’s absorption of calcium.
Bone pain and lower back pain may be signs of inadequate vitamin D levels in the blood.
Large observational studies have found a relationship between a deficiency and chronic lower back pain.
2.You Have Gut Trouble
Remember, vitamin D is a fat-soluble vitamin, which means if you have a gastrointestinal condition that affects your ability to absorb fat, you may have lower absorption of fat-soluble vitamins like vitamin D as well. This includes gut conditions like Crohn’s, celiac and non-celiac gluten sensitivity, and inflammatory bowel disease.
A depressed mood may also be a sign of deficiency. On the other hand, most of the controlled trials, which carry more scientific weight than observational studies, didn’t show a link between the two
Some controlled studies have shown that giving vitamin D to people who are deficient helps improve depression, including seasonal depression that occurs during the colder months.
Hair loss is often attributed to stress, which is certainly a common cause. However, when hair loss is severe, it may be the result of a disease or nutrient deficiency.
Hair loss in women has been linked to low Vitamin-D levels, although there is very little research on this so far
In a case study, topical application of a synthetic form of the vitamin was found to successfully treat hair loss in a young boy with a defect in the Vitamin-D receptor.
A depression diagnosis is often actually linked to a shortage of vitamin D. While the jury is still out about why, the Vitamin D Council says that the mineral may work in the same brain areas—and impact the same hormones, like serotonin—as those that affect mood.
6.Fatigue and Tiredness
Feeling tired can have many causes and vitamin D deficiency may be one of them. Unfortunately, it’s often overlooked as a potential cause.
In one case, a woman who complained of chronic daytime fatigue and headaches was found to have a blood level of only 5.9 Nanograms per milliliter. This is extremely low, as anything under 20 Nanograms per mililiter is considered to be deficient.
