Vitamin A properties

Cholecalciferol - it is an organic chemical compound from the group of vitamin D. It is soluble in fats and has the ability to store in the body. He is best known for his influence on the calcium economy and its positive effect on bones, but in recent years much more health properties of vitamin D have been discovered for practically every system in our body. It is synthesized in the skin under the influence of UV-B rays on 7-dehydrocholesterol.
Widespread vitamin D deficiency in society
It is estimated that up to 90% of the population may have insufficient level of vitamin D in the blood. This makes the vitamin gaining an inglorious title of the most missing vitamin in the body. The reason for this may be a small exposure to sunlight from 11-14 hours, which is characterized by the highest UV-B emission. Unfortunately, these hours coincide with the working time of the majority of society, which means that it is not possible to use the healthy properties of the sun.
Economy of calcium and phosphorus
Vitamin D effectively supports the absorption of these minerals in the gut, and then has a positive effect on their use. It also helps to regulate the level of calcium in the blood. The reduction in the level of parathyroid hormone by vitamin D may contribute to limiting the release of calcium from bone stores, allowing for a higher bone mineral density.
Well-being and mental health
Cholecalciferol is characterized by a strong influence on the mood regulation. Research shows that the low level of this vitamin in the blood increases the risk of depression and disorders associated with well-being. Deficiencies in vitamin D are also associated with deterioration of sleep quality, supplementation with highly concentrated vitamin can effectively solve problems with falling asleep. Better sleep means more energy during the day and more efficient functioning of the whole body. Vitamin D has the ability to modulate calcium channels in neurons. It can also control cell death by excitotoxicity. One can be tempted to say that this vitamin protects the nervous system and can help to preserve mental performance for a long time.
Hormonal activity of vitamin D
The view on this vitamin has changed radically when specific VDR receptors (vitamin D receptors) have been discovered in most cells of the human body. This has thrown a new light on its functionality, because it is indicative of hormonal activity.
Effect on testosterone
Supplementation with cholecalciferol contributes to the increase in testosterone levels in men who previously complained about its low level. It may also result in a decrease in SHBG, or globulin binding sex hormones, which increases the concentration of biologically active free testosterone. What's more, the effect of vitamin D supplementation on the slowdown of androgen decline resulting from the aging of the body was observed, which allows you to enjoy vitality for a long time.
Benefits for athletes
The effect on muscle work translates into better control over the body and stronger activation of muscle fibers to work. Regulation of androgen levels and tissue sensitivity to insulin allows maximizing anabolic processes and optimal use of nutrients. A beneficial effect on the reduction of adipose tissue can also be noted, among others due to elevated adiponectin. Research confirms the effect on the severity of fat burning in people who previously suffered from a deficiency of vitamin D.
