5 signs that show you are in VITAMIN D DEFICIENCY

Vitamin D is very important, considered a hormone, it has many effects on many systems.
Long thought of as a simple vitamin like the others: A B C K E ...

Vitamin D is much more than that ...



Here are the 5 signs and symptoms of vitamin D deficiency
1 - You are often sick or infected
One of the most important roles of vitamin D is the strengthening of the immune system, allowing the latter to fight viruses and other infections that cause disease.

It interacts directly with the cells of the immune system! (3)

Indeed, it has long been believed that vitamin D acts indirectly in immune function, only today we know that the power of vitamin D lies in the fact that it is absolutely necessary for the immune system!

If you are often sick, often have a cold or the flu, then you are probably vitamin D deficient.

Several studies have demonstrated a link between this deficiency and respiratory infections such as colds, bronchitis and pneumonia (4,5).

In addition, other scientific publications have shown that supplementation of 4,000 IU per day may reduce the risk of respiratory infections (6, 7, 8).

Finally, a study of people with chronic obstructive pulmonary disease found that those who suffered from severe vitamin D deficiency had significant benefits on their pathology after supplementation (9).

2 - You are often tired
Nowadays, we notice something that was unknown before: chronic fatigue, doctors have even made a syndrome!

Chronic fatigue syndrome!



However, today we have evidence that leads us directly to vitamin D and more particularly to vitamin D deficiency.

Case studies have shown that very low levels of vitamin D in the blood can cause intense fatigue and impact the quality of life of the person (10, 11).

Indeed, in one of these cases, a woman, complaining of intense chronic fatigue during the day, was found to have extremely low levels of vitamin D in the blood: 5.9 ng / ml ( normal "is 30ng / ml).

But that's not all !

When this woman stabilized her vitamin D level through dietary supplements, her level reached 39 ng / ml and all her symptoms completely disappeared (12).

However, you can also feel fatigue without being extremely deficient, a small deficiency can also cause fatigue.

An observational study looked at the relationship between vitamin D deficiency and fatigue in young women.

This study showed that women who had a rate below 20 ng / ml or just under 30 ng / ml complained much more fatigue than people with normal rates (13).

Finally, another observational study showed that nurses regularly had a vitamin D deficiency and therefore, regularly complained of fatigue.

The researchers also found that 89% of nurses were deficient in vitamin D (14).

3 - You have bone problems and back pain
As we know, vitamin helps maintain the health of the bone including improving the body's ability to absorb calcium.

Bone and back pain can be a sign of vitamin D deficiency.

Several observational studies have demonstrated a very strong relationship between vitamin D deficiency and chronic back pain (15, 16, 17).

One study examined the association between vitamin D levels and back pain in more than 9,000 older women.

The researchers found that people with disabilities were more likely to have back pain, including severe back pain that limited their daily activities (17).

In a controlled study, people with vitamin D deficiency were nearly twice as likely to have bone pain in the legs, ribs or joints as in normal blood levels (18).

4 - You are subject to depressions
A depressed mood can also be a sign of vitamin D deficiency.

In scientific journals, researchers have linked vitamin D deficiency to depression, particularly in older adults (19, 20).

In addition, in one analysis, 65% of observational studies found a relationship between low blood levels and depression.



On the other hand, most controlled trials, which have more scientific weight than observational studies, have not shown a link between the two.

However, researchers who analyzed the studies noted that vitamin D doses in controlled studies were often very low.

In addition, they observed that some studies did not last long enough to see the effect of taking supplements on mood.


Some controlled studies have shown that giving vitamin D to people with a disability helps to improve depression, including depression.
