You probably know that your body produces vitamin D, when you stay in the sun rays without protecting skin. It's also possible to get sunshine vitamin from foods, like salmon, tuna, eggs and cod liver oil.
Actually vitamin D may be considered as prohormone, which takes part in numerous processes in the body. For example, it plays a role in maintaining your bones and teeth dense, in regulating insulin levels and improving immune response.
In addition to these well-known health benefits, vitamin D was found to fight off depression, help in weight loss and reduce risks of heart disease.
Several studies have also found that there is a link between reproductive processes and vitamin D levels. It may change ovulation rates in women and influence on the sperm count in men. Low levels of this chemical were also associated with some polycystic ovary syndrome symptoms.
Specialists have found that in women, who got assisted reproduction therapy, success of the procedure was significantly higher in those with normal vitamin D levels than in deficient patients.
It's very important for pregnant women to get enough of this fat-soluble vitamin, as its deficiency may increase risks of preeclampsia (raised blood pressure, swelling in the body and breathlessness), gestational diabetes and bacterial vaginosis.
Vitamin D has ability to change cell-to-cell communication. That's why it may help slow down cancer progression by reducing cell propagation and cancer's blood vessels development.
It's interesting that lack of vitamin D may raise risks of autoimmune disorders, like rheumatoid arthritis and multiple sclerosis, in which immune system destroys person's own tissue by mistake.
Even though your body can generate vitamin D, when you simply stay in the sun, deficiency is not uncommon, particularly for dark-skinned people and those, who live in northern regions or highly-polluted areas.
Be aware that constant unexplained fatigue, low mood, painful sensations in the bones, hair loss and muscle aches may indicate too low levels of vitamin D.
If deficiency stays untreated for a long time, it may result in fibromyalgia, osteoporosis, obesity and major depression.
So how much vitamin D is OK for your body? According to recent recommendation, children from one to 18 years, as well as adults younger than 70 years old, need 600 IU (15 mcg) vitamin D a day.
If you find it impossible to attain these amounts from sun light and foods, speak with your doctor about special supplements, which can help you meet body’s needs for this chemical and avoid serious consequences.
