Vitamin D is a nutrient that lacks nine out of ten people in Korea. Even though it is a cheap vitamin that can be easily taken because it can be synthesized naturally if you take only 15 to 30 minutes of sunlight a day. It is pointed out that the problem is that they prefer to live indoors and the use rate of sunscreen is high, but it can't be helped to be sad for some reason.
Of course, vitamin D deficiency is very common in other countries. In southern Europe, 30-60% of the population complain of vitamin D deficiency, and up to 80% in the eastern region, where winter sun is particularly short. That's why all Europeans run outside at sunrise.
What are the symptoms that occur when vitamin D is lacking?
Blood tests are most accurate, but simply check for vitamin D deficiency with the six symptoms below.
One of the common symptoms of severe vitamin D deficiency is chronic severe fatigue. This is because vitamin D keeps the cardiovascular system healthy, reduces inflammation, and helps maintain immunity. It is also related to catching a cold often when you are tired. In fact, the symptoms of vitamin D excess are also fatigue, but few Koreans are affected, right?
Some researchers say frequent muscle pain and muscle weakness are linked to vitamin D deficiency. This is because vitamin D helps absorb calcium and is an important nutrient for strengthening bones and muscles.
Since it is an essential nutrient for calcium absorption, the higher the vitamin D deficiency, the higher the incidence of osteoporosis. Especially in old age, vitamin D synthesis is more difficult, so if you experience unprovoked pain, it is recommended to consult a doctor.
Did you know that vitamin D is involved in hair health and growth? Not only does your hair grow slowly, but losing a lot of weight is also linked to vitamin deficiency. But the biggest causes of hair loss are heredity and hormones, as you know.
Vitamin D is associated with immunity. That's why you get sick often, but if you don't know why, it can be vitamin D deficiency. I can see why doctors often talk about walking in the sun as a panacea.
In fact, there are few direct studies on vitamin D deficiency and depression. However, the medical community believes that when the amount of vitamin D is small, more nutrients are consumed and tired, which can eventually cause mental problems and hormonal disorders. In other words, without the calcium that bones need, muscles and connective tissues use energy to support the skeleton, increasing fatigue. If fatigue builds up, it can affect your mood. It is related to studying and working only when you have physical strength and good emotional control.
In fact, just getting a lot of sun and eating three meals a day is enough. When you are lacking, it is good to put fish such as cod liver oil, salmon, tuna, mackerel, and eel, which are rich in vitamin D, as well as egg yolk, milk, and butter in your meal. It's enough to eat cereal with vitamins for breakfast, eat milk and eggs, and photosynthesize during lunch time!
It is recommended to take supplements after consulting a doctor. If you take a mixture of multivitamins and various nutritional supplements, excessive vitamin D can cause heart and kidney problems.
