Vitamin D deficiency is very common. Information technology'southward estimated that about i billion people worldwide have low levels of the vitamin in their blood (two).

According to a 2011 report, 41.half-dozen pct of adults in the U.S. are deficient. This number goes up to 69.2 percent in Hispanics and 82.1 percent in African-Americans (3).

These are common risk factors for vitamin D deficiency:

• Having dark skin.

• Being elderly.

Several large observational studies take shown a link betwixt a deficiency and respiratory tract infections like colds, bronchitis and pneumonia (5, vi).

A number of studies have found that taking vitamin D supplements at dosages of up to 4,000 IU daily may reduce the risk of respiratory tract infections (7, 8, 9).

In one study of people with the chronic lung disorder COPD, just those who were severely scarce in vitamin D experienced a meaning benefit after taking a high-dose supplement for i year (10).

Bottom Line: Vitamin D plays important roles in allowed function. 1 of the most mutual symptoms of deficiency is an increased gamble of illness or infections.

2. Fatigue and Tiredness

Feeling tired tin have many causes and vitamin D deficiency may be one of them.

Unfortunately, it'southward often overlooked every bit a potential cause.

Case studies accept shown that very low claret levels tin cause fatigue that has a severe negative result on quality of life (11, 12).

In one case, a woman who complained of chronic daytime fatigue and headaches was establish to have a blood level of but 5.9 ng/ml. This is extremely low, as anything under 20 ng/ml is considered to be deficient.

When the woman took a vitamin D supplement, her level increased to 39 ng/ml and her symptoms resolved (12).

However, fifty-fifty blood levels that aren't extremely low may have a negative impact on free energy levels.

A large observational report looked at the human relationship betwixt vitamin D and fatigue in young women.

The report institute that women with blood levels under 20 ng/ml or 21–29 ng/ml were more likely to complain of fatigue than those with blood levels over 30 ng/ml (13).

Another observational study of female nurses found a strong connectedness between depression vitamin D levels and self-reported fatigue.

What's more than, the researchers found that 89 per centum of the nurses were deficient (14).

Bottom Line: Excessive fatigue and tiredness may be a sign of vitamin D deficiency. Taking supplements may help meliorate energy levels.

3. Os and Dorsum Pain

Vitamin D is involved in maintaining bone health through a number of mechanisms.

For i, it improves your body'southward absorption of calcium.

Os pain and lower back hurting may exist signs of inadequate vitamin D levels in the blood.

Large observational studies have found a relationship between a deficiency and chronic lower back pain (15, sixteen, 17).

I study examined the association betwixt vitamin D levels and dorsum pain in more than than ix,000 older women.

The researchers plant that those with a deficiency were more likely to take back pain, including severe back hurting that limited their daily activities (17).

In one controlled written report, people with vitamin D deficiency were near twice equally likely to experience bone pain in their legs, ribs or joints compared to those with claret levels in the normal range (18).

Bottom Line: Low claret levels of the vitamin may be a crusade or contributing factor to os pain and lower dorsum pain.

four. Low

A depressed mood may too be a sign of deficiency.

In review studies, researchers have linked vitamin D deficiency to depression, especially in older adults (19, 20).

In one analysis, 65 percent of the observational studies found a relationship between low claret levels and depression.

On the other mitt, most of the controlled trials, which behave more scientific weight than observational studies, didn't bear witness a link between the two (19).

However, the researchers who analyzed the studies noted that the dosages of vitamin D in controlled studies were ofttimes very low.

In addition, they noted that some of the studies may not have lasted long enough to run across the effect of taking supplements on mood.

Some controlled studies accept shown that giving vitamin D to people who are scarce helps meliorate low, including seasonal depression that occurs during the colder months (21, 22).

Bottom Line: Low is associated with low vitamin D levels and some studies accept found that supplementing improves mood.

five. Impaired Wound Healing

Slow healing of wounds after surgery or injury may exist a sign that vitamin D levels are likewise low.

Results from a test-tube study suggest that the vitamin increases production of compounds that are crucial for forming new skin as part of the wound-healing procedure (23).

Ane study on patients who had dental surgery found that certain aspects of healing were compromised past vitamin D deficiency (24).

It's also been suggested that vitamin D'south office in controlling inflammation and fighting infection is important for proper healing.

One analysis looked at patients with diabetic foot infections.

It institute that those with severe vitamin D deficiency were more likely to have higher levels of inflammatory markers that tin can jeopardize healing (25).

Unfortunately, at this point there is very little research well-nigh the furnishings of vitamin D supplements on wound healing in people with deficiency.

However, one report found that when vitamin D scarce patients with leg ulcers were treated with the vitamin, ulcer size reduced by 28 percentage, on boilerplate (26).

Lesser Line: Inadequate vitamin D levels may lead to poor wound healing following surgery, injury or infection.

6. Os Loss

Vitamin D plays a crucial part in calcium absorption and os metabolism.

Many older women who are diagnosed with bone loss believe they need to accept more calcium. Nevertheless, they may exist deficient in vitamin D besides.

Low bone mineral density is an indication that calcium and other minerals take been lost from os. This places older people, especially women, at an increased run a risk of fractures.

In a large observational study of more 1,100 middle-anile women in menopause or postmenopause, researchers found a potent link between low vitamin D levels and depression bone mineral density (27).

Withal, a controlled study found that women who were vitamin D deficient experienced no comeback in os mineral density when they took high-dose supplements, even if their blood levels improved (28).

Regardless of these findings, adequate vitamin D intake and maintaining blood levels within the optimal range may be a good strategy for protecting bone mass and reducing fracture risk.

Bottom Line: A diagnosis of low os mineral density may exist a sign of vitamin D deficiency. Getting plenty of this vitamin is of import for preserving os mass as yous get older.

7. Pilus Loss

Hair loss is often attributed to stress, which is certainly a common cause.

Still, when pilus loss is severe, it may exist the upshot of a illness or nutrient deficiency.

Hair loss in women has been linked to low vitamin D levels, although at that place is very little research on this so far (29).

Alopecia areata is an autoimmune affliction characterized by severe hair loss from the head and other parts of the torso. It'south associated with rickets, which is a disease that causes soft bones in children due to vitamin D deficiency (30).

Depression vitamin D levels are linked to alopecia areata and may be a take a chance factor for developing the disease (31, 32, 33).

Ane study in people with baldness areata showed that lower blood levels tended to be associated with a more severe hair loss (33).

In a case study, topical application of a synthetic grade of the vitamin was constitute to successfully care for hair loss in a immature boy with a defect in the vitamin D receptor (34).

Bottom Line: Hair loss may exist a sign of vitamin D deficiency in female person-pattern hair loss or the autoimmune condition baldness areata.

8. Musculus Pain

The causes of musculus pain are oft difficult to pinpoint.

In that location is some prove that vitamin D deficiency may exist a potential cause of musculus pain in children and adults (35, 36, 37).

In one study, 71 percent of people with chronic hurting were institute to be scarce (37).

The vitamin D receptor is present in nerve cells called nociceptors, which sense hurting.

One report in rats showed that a deficiency led to pain and sensitivity due to stimulation of nociceptors in muscles (38).

A few studies have found that taking high-dose vitamin D supplements may reduce various types of pain in people who are deficient (39, forty).

One study in 120 children with vitamin D deficiency who had growing pains found that a single dose of the vitamin reduced pain scores by an average of 57 pct (xl).

Bottom Line: There is a link between chronic pain and low claret levels of the vitamin, which may be due to the interaction between the vitamin and pain-sensing nervus cells.

Correcting a Vitamin D Deficiency is Uncomplicated
