Vitamin D3 – is one of the substances we need for the proper functioning. It is one of the vitamins soluble in fat. It is the only vitamin which has steroid structure, is produces from cholesterol, just like the steroid hormones, such as testosterone or cortisol. In the body system, it undergoes multistage transformations. The initial form of cholecalciferol, which is transported to the liver, is converted to calcidiol, and then to the active calcitriol in the kidneys.
Modulation of the immune system functions
Vitamin D promotes the reduction in symptoms associated with the impaired functioning of the immune system, such as asthma or atopic dermatitis. It can shorten the time of colds, as it supports the fight against infections. It contributes also to the reduction in the risk of autoimmune diseases, such as multiple sclerosis, which is interesting information as the number of autoimmune disease cases is nowadays growing.
Vitamin D plays an important role in bones development and their good condition. This is because of the positive influence on bone-forming cells, referred to as osteoblasts, whose membranes are rich in vitamin D receptors. Their activation allows for more effective division and faster maturation.
Not to mention the influence on the absorption and use of calcium and phosphorous, because it is the most important characteristic of vitamin D, and this is a feature we have known the vitamin for since the time of its discovery. The vitamin allows for the more effective transport of the elements mentioned, from the gastrointestinal lumen into the bloodstream, and then for their smoother distribution in the body. Thanks to vitamin D we can also maintain the proper calcium level, because of the reduction in the release of the parathormone which draws calcium out of bone tissue.
Impact on sport condition
Physically active people can be interested in the potential growth in the level of hormone which is particularly important in sports, testosterone. The increase in the level of this steroid means smoother muscle regeneration after training and stronger anabolism, which results in faster sport progression. Vitamin D participates also in the regeneration of muscle functions, and the proper control over muscles is one of the basic elements of success in sports. The studies conducted by the researchers demonstrate also smoother regeneration of muscle fibres damaged due to training.
Protection of the nervous system and mood improvement
Efficient nervous system is essential not only for general well-being and maintenance of cognitive functions, but also for the proper control over the body during the whole life, because any dysfunctions of this system can result in epilepsy, essential tremor or neuropathic pain. In this aspect, protective effects of vitamin D consist mainly in the modulation of calcium channels functions in neurons, which inhibits excitotoxic influence of glutamate due to excessive activation of NMDA receptors in the brain.
It has been demonstrated that vitamin D deficiencies are related to the frequency of depressive disorders; once the deficiency is complemented the researchers reported significant improvement in subjective assessment of life quality and well-being. The researchers indicate also a potential influence of low level of the vitamin on the deterioration in sleep quality, which negatively affects mood during the day, as lack of sleep and regeneration undoubtedly deteriorate the joy of life.
Healthy heart and blood vessels
Maintaining the proper concentration of vitamin D in the body system allows for a reduction in inflammations responsible for atherogenesis, which reduces the risk of atherosclerosis and infarction. Scientific research has demonstrated that supplementation of this vitamin can reduce the number of cardiovascular diseases. Due to the regulation of the renin-angiotensin system, the product can be beneficial also for people struggling with too high blood pressure.
Insulin sensitivity and diabetes
The resistance of cells to insulin action can cause much damage in the body system, because of excessive glycation, caused by too high concentration of glucose in blood, and potential growth of adipose tissue whose excess can increase inflammations because of produced cytokines.
Similarly to other ailments, the researchers reported inverse correlation between the concentration of vitamin D in blood, insulin sensitivity level and the risk of diabetes. The supplementation can contribute to the improvement in many indicators of metabolic health. They include fasting insulin level, test result after glucose load and HOMA index.
Now Foods Vitamin D-3 is recommended to everyone who struggles with vitamin D deficiency, especially if it was confirmed by blood tests. It will be also beneficial for people struggling with fragility of bones and teeth, immune system disorders or depression. It is a perfect preventive healthcare in the cold period, as it complements the level of vitamin which cannot be produced by skin due to the lack of sunlight.
Sunshine vitamin, a true elixir of life. In an ideal world you could spend all day in the sun and thus naturally take care of the level of vitamin D3 in the body. Unfortunately, in our country it is rather impossible. But fortunately we have supplements. Deficiencies of vitamin D3 in our climate are very common, so regular supplementation should be a part of taking care of our own health. According to the manufacturer's suggested dose is 1 tablet per day. It amounts are a little understated. Adults, the elderly and obese should increase the dose to 2 or 4 capsules per day, at least during the period from September to April, when the sun is the least and the natural synthesis of vitamin D-3 is inhibited. Vitamin D3 is fat-soluble, so it must be taken with a meal containing fat. Vitamin D3 combined with vitamin K2. This prevents osteoporosis.

Vitamin D belongs to fat soluble vitamins, occurs in three forms: calciferol (vitamin D1) ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3), it is formed under the action of sunlight for at least 15 minutes per day. In the absence of sunlight it should be administered in the diet in the form of fish oil (Vitamin A + D3) and fish oils. It is responsible for the absorption of calcium and phosphorus. It is the building substance of bone tissue particularly necessary during pregnancy, childhood, and for athletes. It is a component of dietary supplements and nutrients among competetive athletes. Deficiency of vitamin D causes children growth inhibition, and rickets.
For adults - deficiency causes osteomalacia.
Excess of vitamin D causes headaches, alopecia, nausea, drowsiness, blurred vision, pain in the long bones, the deposition of calcium deposits.
Dosage: 400 IU units during the day.
Cholecalciferol, or vitamin D3, is an organic chemical that belongs to the family of D vitamins. It is naturally found in fatty fish, fish oil, egg yolks, milk and dairy products. It is also synthesized in the human body. It is formed from 7-dehydrocholesterol present in the keratinocytes of the spinous and the basal layers of the epidermis, and a pre-requisite for initiating this process is the action of 290-315 nm wavelength UVB radiation on the skin.
Cholecalciferol is a biologically inactive compound. In the body, it undergoes enzymatic hydroxylation – first in the liver, with the participation of 25-hydroxylase, when calcidiol is formed and secondly in the kidneys, where under the influence of 1-α-hydroxylase, calcidiol is converted into the final active form – calcitriol.
The most important role of vitamin D3 in the body is the regulation of calcium-phosphate metabolism, which directly affects normal skeletal mineralization. In addition, it is involved in cell proliferation and differentiation, insulin secretion, as well as in some functions of the nervous, endocrine and immune systems.
Cholecalciferol is the most popular form of vitamin D used in dietary supplements. Studies show that supplementation with vitamin D in this form most effectively and rapidly raises the level of 25 (OH) D3 – a metabolite that is a marker of the level of vitamin D in the body.
Dosage: according to RDI standards for individual age groups.
Lanolin is obtained in the process of cleaning of raw sheep wool from the so-called wool fat, protecting it from getting wet and unbeneficial weather conditions.
Lanolin is commonly used for the production of ointments and creams with lubricating and softening effect, however, it also found application in the production of dietary supplements and more precisely vitamin D3.
In order to obtain vitamin D3 from lanolin, it undergoes cleaning and crystallization and then proper chemical processes, as a result of which 7-dehydrocholesterol is produced - a precursor of vitamin D3, the same which is produced in skin under the influence of UV radiation. 7-dehydrorocholesterol obtained from lanolin is then subjected to the above mentioned radiation, being transformed to vitamin D3.
