Depression related to vitamin D3 deficiency

The link between mood and vitamin D3 deficiency is obvious and has been confirmed by numerous scientific studies. These findings convince us of the usefulness of this vitamin for disorders such as depression, seasonal affective disorder (SAD), anxiety, and even schizophrenia.

An important study carried out in 2006 among elderly people proved that the lower the blood level of vitamin D3, the more marked the psychological disorders (anxiety, depressive state, sleep disorders...), are. Deficient people are statistically up to 11 times more depressed than those with normal blood levels.

Here are 2 scientific hypotheses concerning the consequences of a lack of this vitamin: a lack of vitamin D3 could directly affect the dopamine and norepinephrine receptors, which in the long term can lead to depression.

It has been proven that vitamin D3 helps synthesize the enzymes essential for the synthesis of catecholamine, dopamine, adrenaline, noradrenaline and other neurotransmitters all associated with bipolar disorders, schizophrenia, and of course, depression.

D3 insufficiency is also very frequently associated with hyperthyroidism, which is almost always coupled with a depressive state in women as in elderly men.

The other hypothesis is based on the excessive or deficient response of the immune system, both of which can lead to chronic inflammation, an inflammation maintained by the lack of vitamin D3, as well as by worry, anxiety and depression.

In addition to regulating certain neurotransmitters, the immune system and inflammation, it also regulates glucocorticoids (stress hormones belonging to the corticosteroid family), and it is known that a deficiency of this type of hormone can lead to mental disorders.

If we review the virtues of vitamin D3, we see that it is not just a vitamin, it is also an essential prohormone or cofactor that reinforces the activity of other hormones or hormonal precursors. For example, exposure to the summer sun, which increases the level of vitamin D3, leads to an increase in the level of serotonin, which is useful for restful sleep and a good mood. It is this prohormone synthesized by the action of the solar spectrum that naturally becomes scarce in winter.

Remember that blood levels of vitamin D3 are easily measured by a simple blood test. Remember that to obtain an optimal level and therefore an ideal health, you can reach 5000 international units (IU) daily without any problem (5000 IU correspond to 2 g).

It is interesting to know that we can strengthen, stabilize and preserve our mental health with an adequate intake of vitamin D3.
