Vitamina D-3 Natural 2000 UI - 200 Comprimidos Recubiertos, Paquete de 2

What is Vitamin D and why is it important?

Vitamin D, known as the 'sunshine vitamin,' is a fat-soluble nutrient essential for the body. It is synthesized in the skin after exposure to sunlight, but in Spain, especially during autumn and winter, UV radiation is insufficient to produce optimal amounts. This makes supplementation a practical option to maintain adequate levels. Vitamin D3 (cholecalciferol) is the form most used by the human body, as it is identical to what we produce naturally. This Basic Vitamins supplement provides 2000 IU per tablet, in an economical pack of two bottles with 200 tablets each, ideal for a prolonged supply.

Health Benefits of Vitamin D

According to the European Food Safety Authority (EFSA), vitamin D contributes to various key physiological functions. Supported benefits include: contributes to the normal absorption and utilization of calcium and phosphorus, to the maintenance of normal blood calcium levels, to the maintenance of normal bones, to normal muscle function, and to the normal function of the immune system. These effects are especially relevant for bone health and defense against infections. However, it is important to remember that vitamin D is a supplement, not a medication, and should not be used to prevent, treat, or cure diseases.

How much Vitamin D do you need? Recommended dosage

The recommended daily allowance (RDA) for adults in the European Union is 15 µg (600 IU) per day. However, many people, especially those with low sun exposure, dark skin, or certain medical conditions, may benefit from higher doses. The tolerable upper limit established by EFSA is 100 µg (4000 IU) per day. This supplement offers 2000 IU per tablet, a dose that falls within a safe and effective range for most adults. It is recommended to take one tablet daily with a meal, preferably one containing some fat to improve absorption. Each bottle contains 200 tablets, providing more than six months of supplementation per bottle; the 2-pack covers more than a year.

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 the one produced in human skin. Research indicates that vitamin D3 is more effective at raising and maintaining serum levels of 25-hydroxyvitamin D, the storage form in the body. Therefore, most experts recommend D3 supplementation. This product contains natural vitamin D3 obtained from lanolin, ensuring a highly bioavailable form compatible with the body.

How to choose the best Vitamin D supplement

When choosing a vitamin D supplement, it is essential to consider the form (D3 preferably), dosage, purity, and certifications. This Basic Vitamins product comes in coated tablets, easy to swallow, and is formulated without sugar, starch, preservatives, or artificial colors or flavors. In addition, it is gluten-free, making it suitable for people with gluten sensitivity. The pack of two bottles offers excellent value for money. To ensure quality, the product is manufactured under strict quality controls. Remember that food supplements should not replace a varied and balanced diet.

Possible side effects and contraindications

Vitamin D is safe at recommended doses. However, excessive and prolonged intake (more than 4000 IU per day) can cause toxicity, with symptoms such as nausea, vomiting, loss of appetite, and weakness. It can also raise blood calcium levels (hypercalcemia), affecting the kidneys. People with conditions such as sarcoidosis, hyperparathyroidism, or kidney stones should consult a doctor before taking supplements. Do not exceed the recommended daily dose. This product is a food supplement and should not be used as a substitute for a balanced diet.
