Unlike the health of other limbs, bone health is often forgotten. In fact, bones play an important role in the body’s system. Bones serve as builders, part of the organ of movement, protectors of important organs of the pulmonary heart, etc., home to stem cell “factories”, hematopoietic systems, main mineral reserves and other functions that we do not yet know.
Vitamin D is a useful nutrient for bone formation. Vitamin D is also needed by the body to maintain the health of the heart, brain, and muscles.
Vitamin D is formed naturally when the skin is exposed to direct sunlight. In fact, most vitamin D needs are met through sun exposure. In addition, vitamin D is also contained in several types of foods, such as mushrooms, egg yolks, as well as fish. This type of vitamin D is referred to as vitamin D2 or ergocalciferol.
When calcium levels in the body are reduced, the parathyroid glands will stimulate the intestines and kidneys to produce vitamin D to absorb more calcium.
However, not a few people are deficient in vitamin D. This usually happens when the body does not get enough sunlight, or is not effective in absorbing vitamin D. In such conditions, Vitamin D supplements are needed to prevent vitamin D deficiency.
What is Vitamin D?
Vitamin D is known as the sun’s vitamin produced by the body when we are in the sun. In addition, vitamin D can be obtained from foods and supplements.
Vitamin D is a vitamin that belongs to the group of vitamins that easily dissolve in fat. Vitamin D is also referred to as ‘sun vitamin’ because this vitamin is produced from the process of converting cholesterol into calcitriol when the skin is exposed to sunlight, to then calcitriol is delivered to the kidneys and liver until vitamin D is created, precisely vitamin D3 or Calciferol.
We still love vitamins after a century, they were discovered, with half the population of the United States and The United Kingdom takes supplements. Vitamin D–a vitamin of sunlight–is the most favorite and is believed to have the most proven benefits.
Many governments, including the UK government, have said that the evidence of the health benefits of vitamin D is so great that every older person should take it as a supplement at least six months of the year.
One of the main foods of the bones is Vitamin D. Vitamin D plays an important role in regulating calcium and phosphorus levels in the blood. Calcium and phosphorus are two very important factors when it comes to maintaining bone health. The body needs vitamin D to absorb calcium to the maximum in the intestine, as well as help build strong bones and teeth.
Vitamin D is also a receptor on almost all cells, so why people who are deficient in vitamin D tend to get infections, because the commander of his immune system is weak.
This vitamin was first used to cure rickets disease in children in Victoria who live in poor towns and are now routinely given to them to prevent and treat brittle bone disease (osteoporosis) and fractures. This has been linked to a decrease in the risk of common diseases in observational studies, ranging from depression to cancer.
The largest clinical study ever conducted on the benefits of vitamin D in preventing fractures is now reported in the BMJ, with more than 500,000 people and about 188,000 fractures from 23 groups of people who have the same criteria for different countries.
Because vitamin D levels are strongly influenced by genes, the researchers used genetic markers for vitamin D levels in the blood (called Mendelian randomisation or MR) to avoid normal observational study biases, such as confusing disease causes and consequences and other effects related to health behaviors (called confounding factors).
