Igennus Vitamina D3 2000 UI, 50 mcg, 365 Comprimidos Vegetarianos - Suministro para 1 Año

What is vitamin D and why is it important?

Vitamin D is an essential nutrient that plays key roles in the body. Known as the "sunshine vitamin," it is synthesized in the skin when we are exposed to sunlight. However, during the winter months or in people with little sun exposure, it can be difficult to get enough from sunlight alone. Furthermore, few foods naturally contain vitamin D, so supplements are a practical option to maintain adequate levels.

This product provides 2000 IU (50 mcg) of vitamin D3, the biologically active and preferred form by the body. Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, the maintenance of normal bones, normal muscle function, and the normal functioning of the immune system. With 365 tablets, it offers a complete year's supply, facilitating consistent and uninterrupted supplementation.

Health benefits of vitamin D

Vitamin D is fundamental for various physiological processes. According to the European Food Safety Authority (EFSA), vitamin D has been shown to contribute to:

• The normal absorption and utilization of calcium and phosphorus, essential for bone mineralization.
• The maintenance of normal blood calcium levels.
• The maintenance of normal bones.
• Normal muscle function.
• Normal immune system function.

These benefits make vitamin D important for people of all ages, especially during winter or in people at higher risk of deficiency, such as older adults, pregnant women, or those with little sun exposure. The dose of 2000 IU per day is an effective and safe amount for most adults, always within the limits established by health authorities.

How much vitamin D do you need? Recommended dose

Daily vitamin D requirements vary according to age, sun exposure, and general health status. In Spain, the recommended daily intake for adults usually ranges between 600 and 2000 IU, although in winter it can be higher. This supplement provides 2000 IU per tablet, an adequate dose for most adults looking to maintain optimal levels.

It is important not to exceed the tolerable upper limit of 4000 IU per day (100 mcg) unless under medical supervision. With one tablet a day, this product stays within safe margins. Each package contains 365 tablets, which facilitates a daily routine without the need to reorder frequently. Remember that food supplements should not be used as a substitute for a balanced and varied diet.

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 form produced by human skin. Vitamin D3 is considered more effective for maintaining and raising blood levels of vitamin D. This product uses cholecalciferol obtained from lanolin (sheep's wool fat), which makes it suitable for vegetarians, but not for vegans. The D3 form binds better to the body's receptors and has a longer half-life, making it the preferred option for supplementation.

How to choose the best vitamin D supplement

When selecting a vitamin D supplement, it is important to consider several factors: the form (D3 versus D2), the dose, the purity, and the quality of the product. This supplement stands out for its Clean Label formula: no silicon dioxide, magnesium stearate, titanium dioxide, artificial colors, or unnecessary fillers. It is hypoallergenic, non-GMO, and manufactured in the UK under strict GMP standards. The tablets are small and odorless, easy to swallow, and do not contain oils, which can be beneficial for people with fat malabsorption issues.

Possible side effects and contraindications

At recommended doses, vitamin D3 is generally safe and well-tolerated. However, very high doses (more than 4000 IU per day for prolonged periods) can lead to toxicity, manifesting as high blood calcium levels (hypercalcemia), which can cause nausea, weakness, or kidney problems. If you are pregnant, breastfeeding, have any medical condition, or are taking other medications, consult a healthcare professional before starting supplementation. This product should not be used as a substitute for a balanced diet.
