A few years ago, patients came for treatment abroad and said, they did so many tests in Bangladesh, no one could catch that vitamin D is low in my blood!
However, the American and European Endocrine Societies agree that there is no need for vitamin D testing on a mass scale unless necessary. But this expensive test has now become a routine test. And you should also know that vitamin D is not a specific treatment for any disease.
The boatman who crosses the river while singing, the farmer who works in the fields, may not always have the right amount of nutrients in their food, but vitamin D testing will show the right amount in the blood. Because, another name of vitamin D is 'sunshine vitamin'. When we are exposed to sunlight, vitamin D is produced spontaneously from cholesterol stored in the skin. Then it enters the blood and goes to the liver and kidneys to become active vitamin D. That is, stronger. Its function in the body is to absorb blood calcium and maintain its proper amount, keep bones strong and strong, maintain muscle strength, prevent against some diseases, etc. Although a type of vitamin, D is now called a hormone due to its many metabolic effects.
Sunlight contains ultraviolet rays, which are used to make vitamin D. But if there is more melanin in the skin, less vitamin D is produced. Melanin is a natural sunscreen that protects us from UV rays. Acts like armor. Since dark skin (dark skin) has more melanin than white skin, dark skin will produce less vitamin D.
