Sufficient reserves of this vitamin in the human body have a positive effect not only on immunity, but also on a person's physical condition and strengthen the heart.
Researchers at the University of Virginia in the United States have proven that adequate vitamin D levels in the human body have a positive effect not only on immunity but also on physical well-being. They also have a beneficial effect on the heart and blood vessels.
This conclusion was reached using a statistical method. Volunteers from medical institutions participated in the experiment. Initially, all participants underwent a medical examination. Their dietary preferences and unhealthy habits were also studied. Throughout the experiment, the participants were given varying doses of vitamin D and were required to perform specific physical activities.
The results showed that volunteers who took larger amounts of fish oil, which contains vitamin D, were able to withstand physical exertion several times better than others.
It was also found that this vitamin has a positive effect on both men and women, regardless of their age.
This study is not the only one. Numerous similar studies have previously been conducted to confirm the benefits of vitamin D on the human body. The benefits of this vitamin for bones and joints have long been known.
Also, before all sorts of scientific experiments were conducted, people noticed that damaged bones healed faster if they were regularly exposed to the sun. This is because the sun accelerates the synthesis of vitamin D.
Molecular biologists also conducted experiments on worms, giving them massive doses of vitamin D. This strengthened the immune system and activated receptors that protect cells from malignant transformation.
However, scientists say that excessive vitamin D consumption is dangerous to health. To ensure it benefits the body, it's important to correctly calculate the optimal dose. To do this, you need to have your blood tested for vitamin D levels. Then, you can calculate the correct dosage.
