BioTechUSA Vitamin D3 2000 IU – 60 Tablets

BioTechUSA Vitamin D3 is a vitamin D dietary supplement in tablet form, containing 50 micrograms (2000 IU) of vitamin D per tablet (1000% NRV). Vitamin D, or cholecalciferol, is a fat-soluble vitamin that the body produces in the skin through exposure to sunlight. During the autumn-winter period, when sunlight is scarce, ensuring adequate vitamin D intake is particularly important, as at northern latitudes UVB radiation is too weak for most of the year for the skin to produce sufficient amounts of the vitamin.

In the Estonian climate, dark months last a long time, and sunlight is not sufficient to ensure natural vitamin D production from October to April. Therefore, it is recommended to pay special attention to vitamin D intake through dietary supplements during the autumn-winter period. Good natural sources of vitamin D include fatty sea fish (cod, salmon, tuna), cod liver oil, various dairy products and egg yolk, but it is difficult to obtain a sufficient daily dose from regular food. BioTechUSA Vitamin D3 is a convenient and effective choice for supplementing vitamin D intake, as a single tablet covers the daily requirement more than tenfold.

Vitamin D performs several important physiological functions in the body. It contributes to the maintenance of normal bones and teeth and to healthy muscle function. Vitamin D contributes to the normal absorption and utilisation of calcium and phosphorus in the body, playing a key role in ensuring skeletal strength. Vitamin D also contributes to the normal function of the immune system, which is particularly important during cold months when viral illnesses are more common.

Active ingredient

Vitamin D (cholecalciferol, also known as D3) is a fat-soluble vitamin that is essential for the normal functioning of the body. Unlike many other vitamins, vitamin D acts as a hormone in the body, influencing bone mineralisation, immune system function, and the metabolism of calcium and phosphorus. BioTechUSA uses the D3 form (cholecalciferol), which is the most bioavailable form of vitamin D and the same form that human skin produces when exposed to sunlight. Like all BioTechUSA products, Vitamin D3 is made from safe and carefully selected ingredients.
