Aliness Vitamin D3 5,000 IU is a dietary supplement containing 5,000 IU cholecalciferol in one tablet.

Cholecalciferol is an organic chemical compound belonging to D vitamins. It is a fat-soluble vitamin that can be stored in the body. Cholecalciferol is best known for its effect on calcium metabolism and positive effects on bones, however, in recent years, much more health benefits of vitamin D have been discovered for virtually every system in our body. It is synthesized in the skin under the influence of UV-B rays on 7-dehydrocholesterol.

Widespread deficiencies
It is estimated that up to 90% of the population may have insufficient vitamin D in their blood. This is why the vitamin has gained the infamous name of the most deficient substance.

The reason for this may be low exposure to sunlight between 11 a.m. to 2 p.m, during which the emission of UV-B rays is the highest. Unfortunately, these are the hours that coincide with the working hours of most of the population, so there is no possibility to benefit from the health-promoting properties of the sun.

Calcium and phosphorus balance
Vitamin D effectively supports the absorption of calcium and phosphorus in the intestines, and then positively affects their use. It also helps to regulate blood calcium levels. Lowering the level of parathyroid hormone by vitamin D may contribute to limiting the release of calcium from bone stores, allowing the maintenance of a higher mineral density.

Well-being and mental health
Cholecalciferol exerts a strong effect on the regulation of mood. Low levels of this vitamin in the blood are said to affect an increased risk of depression and well-being worsening.

Vitamin D deficiencies are also associated with poor sleep quality, which can be improved after deficiency replenishment. Better sleep, subsequently, means more energy during the day and better functioning of the whole body.

Vitamin D can modulate calcium channels in neurons. It can also control cell death by excitotoxicity. Therefore, it might be said that this vitamin protects the nervous system and may contribute to maintaining mental efficiency for a long time.

The hormonal activity of vitamin D
The perception about vitamin D changed dramatically when specific VDR receptors (vitamin D receptors) were discovered in most cells of the human body. This shed new light on the vitamin’s functionality, as it indicates hormonal activity.

Impact on testosterone levels
Cholecalciferol supplementation contributes to an increase in testosterone levels in men who have previously complained about its low level. It may also result in a decrease in SHBG, i.e. sex hormone-binding globulin, thanks to which the concentration of biologically active free testosterone increases.

What's more, vitamin D supplementation proved to slow down the age-associated decline of androgens, which prolongs vitality.

Benefits for athletes
The effect of vitamin D on muscle work translates into better control over the body and stronger activation of muscle fibers. Regulation of androgen levels and tissue sensitivity to insulin allows maximization of anabolic processes and optimal use of nutrients.

A beneficial effect of vitamin D3 may also be noted on adipose tissue, e.g. due to elevated adiponectin. Studies confirm a subtle effect on the increase in burning of body fat in people who had previously suffered from vitamin D deficiency.

To sum up, Aliness Vitamin D3 5,000 IU is recommended in cases of diagnosed vitamin D deficiency in the blood. It can also be used to improve general health and as a support for people who train intensively.
