Vitamina D3 2000 UI - 220 comprimidos - Nm

What is vitamin D and why is it essential?

Vitamin D is a fat-soluble nutrient that plays a fundamental role in bone health and the immune system. Unlike other vitamins, our body can produce it when exposed to the sun, but the lack of sunlight, especially in winter months or in Nordic climates, means that many people need an extra supply through food or food supplements.

Many people do not get enough vitamin D from diet alone, so supplementation can be an effective way to maintain optimal levels.

This product provides **vitamin D3 (cholecalciferol)**, the most bioavailable form and the one the body uses naturally. Each tablet contains **2000 IU (50 mcg)**, an effective dose to cover the daily needs of most adults. Presented in a practical **220-tablet** container, it allows a simple regimen of one tablet per day.

Benefits of vitamin D backed by EFSA

The European Food Safety Authority (EFSA) has approved several health claims for vitamin D, which are detailed below:

• Contributes to the normal absorption and utilization of calcium and phosphorus. This is essential for maintaining strong bones and teeth.
• Contributes to the maintenance of bones under normal conditions. Vitamin D helps fix calcium in bone tissue, reducing the risk of fragility.
• Contributes to normal muscle function. An adequate concentration of vitamin D promotes muscle function and mobility.
• Contributes to the normal functioning of the immune system. It participates in the activation of the body's defenses, helping to maintain natural defenses.
• Contributes to the maintenance of normal blood calcium levels. It regulates calcium balance, fundamental for nerve transmission and muscle contraction.

These claims are approved by EFSA after reviewing scientific evidence.

These benefits are scientifically recognized and apply to the general population. It is important to remember that food supplements do not replace a varied and balanced diet.

How much vitamin D3 do I need per day?

Vitamin D needs vary according to age, sun exposure, and health status. EFSA establishes an adequate intake of 15 µg (600 IU) per day for adults, and 20 µg (800 IU) for those over 70 years of age. However, many people benefit from higher doses to reach optimal levels.

This supplement provides **2000 IU (50 µg)** per tablet, a dose higher than the recommended intake but considered safe for most adults. It is recommended to take one tablet a day, preferably with a meal containing fat to improve its absorption. Before starting any supplementation, consult a healthcare professional, especially if you are pregnant, breastfeeding, or taking other medications.

It is important not to exceed the recommended daily dose and to consult a healthcare professional before starting supplementation, especially in case of pregnancy or pre-existing diseases.

Differences between vitamin D2 and D3: which one to choose?

There are two main forms of vitamin D: ergocalciferol (D2), of plant origin, and cholecalciferol (D3), of animal origin (lanolin) or synthetic. D3 is the form produced by human skin and is considered more effective in raising and maintaining plasma vitamin D levels. Numerous studies indicate that D3 has a greater affinity for cell receptors and a longer half-life than D2.

Although D3 is more effective, vitamin D2 can also be a suitable option for those following a vegan diet, although its bioavailability is lower.

This product contains **vitamin D3 (cholecalciferol)**, which guarantees high bioavailability and prolonged action. If you are looking for a vegan option, D2 or D3 of lichen origin are alternatives, but in terms of efficacy, D3 remains the most studied option.

How to choose the best vitamin D supplement

When selecting a supplement, it is important to look at the form, dose, and quality of the product. Vitamin D3 is the most recommended for its efficacy. The dose should be adjusted to your needs; for general maintenance, 2000 IU daily is a safe option for adults. In addition, look for products from recognized brands that follow good manufacturing practices.

The tablet format is comfortable and easy to swallow, ideal for daily consumption.

Possible side effects and contraindications

Vitamin D is safe at recommended doses. However, excessively high doses (above 4000 IU per day for prolonged periods) can cause hypercalcemia, whose symptoms include nausea, weakness, and kidney problems. Do not exceed the recommended daily dose. Keep the product out of the reach of children. If you have any medical condition or are taking medications, consult your doctor before using this supplement.

This product is a food supplement, it should not be used as a substitute for a balanced diet.
