It is very difficult for the body to get vitamin D from food, so it is easy for us to be deficient in this vitamin.
The benefits of vitamin D most of us know: Vitamin D strengthens bones, improves mood and helps get rid of excess weight more effectively. However, we often do not know if our body is deficient in vitamin D. If you notice one or more of the following symptoms, contact your doctor for a blood test (the supplement should not be taken on its own as it must first be determined if a vitamin D deficiency is present).
* Muscle weakness.
Reduced muscle mass can be the result of a lack of vitamin D in muscle and nerve tissue, says Kimberly Muller, an American athletic trainer. Therefore, if you find that you are unable to do as much exercise as you used to, you may need to get vitamin D.
* Risk to bone .
When a bone is subjected to stress for a long time, it can form small cracks.
Vitamin D promotes bone growth, so if your body lacks this vitamin, bones become weak, so the risk of “stress fractures” increases. Research shows that severe deficiency of this vitamin doubles the risk!
* Blood pressure increases.
Vitamin D is also involved in the functioning of the heart, helping to regulate blood pressure. So, if this vitamin is lacking, blood pressure can increase.
* Sleepy .
A study in the Journal of Clinical Sleep Medicine found that low levels of vitamin D make us feel sleepy during the day.
* Uncomfortable .
Before blaming erratic weather, people around you, or perimenopause, remember that vitamin D affects levels of serotonin in the brain responsible for mood.
* Decreased stamina.
Several studies have concluded that the ability to perform exercise is reduced with vitamin D deficiency.
