Bio-Tech D3 (Colecalciferol) 1000 UI 100 cápsulas

What is Vitamin D and why is it important?

Discover Bio-Tech (Cholecalciferol) 1000 — Vitamin D is an essential nutrient that plays a fundamental role in multiple bodily functions. Known as the "sunshine vitamin," it is synthesized in the skin after exposure to sunlight, but can also be obtained through diet and supplements. Vitamin D3, or cholecalciferol, is the most effective form for raising blood levels of this vitamin, as it is the same form produced by the human body.

In Spain, solar radiation is sufficient during the summer months, but in winter, exposure decreases, leading many people to have suboptimal levels. Therefore, supplementation with vitamin D3 has become a recommended practice for maintaining optimal health.

Health benefits of Vitamin D

Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, key elements for bone mineralization. Additionally, it helps maintain bones in normal conditions and participates in the normal functioning of muscles and the immune system. These benefits are supported by the European Food Safety Authority (EFSA).

Adequate vitamin D levels can also contribute to dental health and general well-being. It is important to note that these are recognized physiological functions, not therapeutic claims. Vitamin D does not prevent or treat diseases by itself, but it is an essential component for the proper functioning of the body.

How much Vitamin D do you need? Recommended dosage

The recommended daily dose of vitamin D varies depending on age, lifestyle, and sun exposure. For adults, the reference intake in the EU is 5 µg (200 IU) per day, but many health authorities suggest higher amounts, especially in people with little sun exposure. The Bio-Tech D3 product provides 1000 IU (25 µg) per capsule, a moderate dose that falls within the safe limits established by the EFSA (maximum tolerance of 100 µg/day for adults).

It is recommended to take one capsule daily, preferably with a meal containing fats to promote its absorption. It is always advisable to consult a healthcare professional before starting any supplementation, especially if taking other medications or having pre-existing health conditions.

Differences between Vitamin D2 and D3

There are two main forms of vitamin D: D2 (ergocalciferol), of plant origin, and D3 (cholecalciferol), of animal origin and also the one produced by the human body. D3 is considered more effective at raising and maintaining blood vitamin D levels, as it has a higher affinity for transport proteins and a longer half-life. For this reason, most supplements opt for D3, as is the case with Bio-Tech D3.

For people following a vegan diet, there are sources of D3 obtained from lichens, although most commercially available D3 comes from lanolin (sheep's wool fat). This product is formulated with cholecalciferol, the most bioavailable form.

When choosing a vitamin D supplement, it is important to consider the form (D3 preferably), the dosage (adapted to your needs), the presentation (capsules, drops, tablets), and the quality of the manufacturer.
