What is vitamin D and why is it important?

Discover Nature's Truth High — Vitamin D is an essential fat-soluble nutrient that performs multiple functions in the body. Often called the "sunshine vitamin," it is produced in the skin after exposure to sunlight, but is also obtained through diet and supplements. Its most active and bioavailable form is vitamin D3 or cholecalciferol, the same one our body synthesizes naturally.

The importance of vitamin D lies in its role in the absorption of calcium and phosphorus, key minerals for maintaining strong bones and teeth. In addition, it contributes to the normal functioning of the immune system and the maintenance of muscle function. In Spain, during the autumn and winter months, solar radiation is insufficient to produce adequate amounts, so supplementation becomes especially relevant.

Benefits of vitamin D for health

Vitamin D has health claims approved by the European Food Safety Authority (EFSA). Its confirmed benefits include:

• Contributes to the normal absorption and utilization of calcium and phosphorus.
• Contributes to the maintenance of normal blood calcium levels.
• Contributes to the maintenance of bones in normal conditions.
• Contributes to the normal functioning of muscles.
• Contributes to the normal functioning of the immune system.
• Plays a role in the process of cell division.

It is important to note that these benefits are obtained as part of a balanced diet and a healthy lifestyle. Vitamin D does not prevent, treat or cure any disease.

How much vitamin D do you need? Recommended dose

The recommended daily allowance (RDA) of vitamin D for adults in the European Union is 5 µg (200 IU), although needs may vary depending on age, sun exposure and health status. Many experts suggest higher intakes, between 600 and 2000 IU per day, to maintain optimal levels. This product provides 1000 IU per softgel, a moderate dose suitable for most adults.

For specific populations such as the elderly, pregnant women or those with low sun exposure, a higher dose may be advisable, always under medical supervision. The EFSA has established a tolerable upper intake level (UL) of 100 µg (4000 IU) per day for adults, so 1000 IU is within a safe range.

Differences between vitamin D2 and D3

There are two main forms of vitamin D in supplements: ergocalciferol (D2) and cholecalciferol (D3). Vitamin D2 is obtained from plant sources, such as UV-exposed yeasts, while D3 comes from lanolin (sheep wool fat) or lichen (suitable for vegans).

Numerous studies indicate that vitamin D3 is more effective in raising and maintaining blood levels of 25-hydroxyvitamin D compared to D2. Therefore, most high-quality supplements contain D3. This product uses cholecalciferol (D3), the form closest to what our body produces.

How to choose the best vitamin D supplement

When selecting a vitamin D supplement, consider the following aspects:

• Form: Opt for vitamin D3 (cholecalciferol) for its higher bioavailability.
• Dose: Choose a dose according to your needs. 1000 IU is a common maintenance dose.
• Presentation: Softgels facilitate absorption by containing the nutrient in a fatty medium.
• Quality: Look for products from recognized brands that follow good manufacturing practices.
• Certifications: If you follow a vegan diet, verify that the D3 is plant-based (lichen). This product is not vegan, as the D3 comes from lanolin.

This pack of 2 bottles of 130 capsules each provides a total of 260 capsules, offering a supply for several months with a single purchase.

Possible side effects and contraindications

Vitamin D is generally safe when taken at recommended doses. However, excessively high doses (above 4000 IU per day for prolonged periods) can lead to toxicity, with symptoms such as nausea, weakness or kidney stones. If you are taking other medications or have pre-existing health conditions, consult your healthcare professional before starting supplementation.

Storage: Store the capsules in a cool, dry place, protected from light and out of reach of children.
