Vitamin D – a vitamin essential for life which is soluble in fats. It is distinguished from other vitamins by its steroid structure and hormonal activity. Vitamin D receptors (VDRs), which are characteristic of this vitamin, are present in most cells of our body. This vitamin is sometimes called a sunshine vitamin because of its synthesis in the skin during which UV-B rays react with 7-dehydrocholesterol and thus form cholecalciferol. After absorption through the skin, cholecalciferol is transported into the liver where it is converted into calcidiol. After reaching the kidneys, calcidiol is converted into calcitriol – a final biologically active form of vitamin D.
The benefits of liquid form
The vitamin administered in a solution may be attractive especially to individuals who do not like or have problems with swallowing capsules and tablets. This form is most frequently recommended for children and the elderly. However, it can interest persons in each age range. The next advantage of this form is that dosage can be adjusted precisely because we can choosing the amount of drops per serving, which is not possible when taking traditional tablets or capsules.
Proper bone development
The growth and development of bones is influenced by the ability of vitamin D to stimulate cell divisions. By activating vitamin D receptors on the surface of osteoblasts, which are bone-forming cells, this vitamin boosts their division and maturation.
The most recognizable function of vitamin D3 is its ability to improve absorption and utilization of calcium and phosphorus. These two elements has a significant impact on mineral density of bones and teeth. Normal vitamin D levels contribute to maintaining optimal calcium blood levels, mainly owing to suppression of parathormone secretion by parathyroid glands.
Immune system function
The immune system is a natural barrier protecting our body against harmful effects of many pathogens. To benefit fully from its capacity, we should provide a favourable environment. One of the factors affecting this condition is proper vitamin D levels.
To sum up, Now Foods Liquid Vitamin D-3 Extra Strength is recommended for individuals for whom it is problematic or just unpleasant to swallow tablets or capsules. It seems to be particularly attractive for children, the elderly or those with swallowing disorders. The supplement is worth interest especially in autumn and spring to support the immune system and in the case of low mineral density of bones, their fragility or mood disorders.
Vitamin D deficiency is estimated to affect more than 50% of the world population. Factors causing lack of vitamin D are: age, kidney disease and liver disease, as well as overweight or obese, and insufficient intake of vitamin D with the diet. Interesting information for active people - this supplement works by increasing muscle mass, especially when used in combination with leucine. It was observed that these compounds used at the same time effect of increasing the insulin, and insulin receptors, which explains their anabolic effect.

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.
