Basic Vitamins Vitamina D3 1000 UI - 200 Comprimidos Recubiertos

What is vitamin D and why is it important?

Vitamin D is an essential nutrient that the body needs to function properly. It is known as the "sunshine vitamin" because the skin produces it when exposed to sunlight. However, in Spain, especially during the autumn and winter months, sun exposure is insufficient to maintain optimal levels. Therefore, vitamin D supplements are a practical option to meet daily needs. This product provides 1000 IU of vitamin D3 (cholecalciferol) per tablet, the form closest to that produced by the human body.

Health benefits of vitamin D

According to the European Food Safety Authority (EFSA), vitamin D contributes to:

• The normal absorption and utilisation of calcium and phosphorus.
• The maintenance of normal blood calcium levels.
• The maintenance of normal bones.
• Normal muscle function.
• Normal immune system function.

These benefits are scientifically recognised and make vitamin D a key nutrient for bone, muscle and immune health.

How much vitamin D do you need? Recommended dose

Vitamin D intake recommendations vary depending on age, lifestyle and sun exposure. EFSA establishes an adequate intake of 15 µg (600 IU) per day for adults, and 20 µg (800 IU) for those over 70. This supplement provides 1000 IU per tablet, a moderate dose that can help maintain adequate levels, especially in people with low sun exposure or increased needs. It is recommended to take one tablet daily, preferably with a meal containing fat to improve its absorption.

Differences between vitamin D2 and D3

There are two main forms of vitamin D in supplements: D2 (ergocalciferol), of plant origin, and D3 (cholecalciferol), which is obtained from lanolin (sheep's wool fat) and is the same form produced by human skin. Research suggests that vitamin D3 is more effective at raising and maintaining blood vitamin D levels. This product uses vitamin D3, making it a particularly efficient option.

How to choose the best vitamin D supplement

When choosing a vitamin D supplement, it is advisable to look at the form (D3 vs. D2), the dose and the quality of the product. This supplement offers 1000 IU of vitamin D3 per tablet, in a 200-coated tablet format that facilitates swallowing. It is an economical and long-lasting presentation, ideal for prolonged daily consumption. In addition, the product is manufactured following strict quality controls, which guarantees its purity and potency.

Possible side effects and contraindications

Vitamin D is safe at recommended doses. However, very high and prolonged doses can lead to toxicity (hypercalcaemia). EFSA sets a maximum tolerable level of 100 µg (4000 IU) per day for adults. This amount should not be exceeded without medical supervision. This product provides 1000 IU, well below the limit, so its normal use is safe. People with kidney disease, sarcoidosis or who are taking medications such as thiazide diuretics should consult their doctor before taking vitamin D supplements.
