Priority One Vitamins Sun D3 3000 UI - 90 Vegetarian Capsules

What is vitamin D and why is it important?

Vitamin D is an essential nutrient that plays a fundamental role in numerous bodily functions. Known as the "sunshine vitamin," it is produced in the skin after exposure to sunlight. However, in the northern hemisphere, especially during the winter months, skin production is drastically reduced, making it necessary to obtain it through diet or food supplements.

Priority One Sun D3 provides 3000 IU of vitamin D3 (cholecalciferol) per vegetarian capsule. Vitamin D3 is the most bioavailable form, similar to that generated by our body. This product has been formulated to help cover daily needs, especially in people with limited sun exposure, frequent use of sunscreens, or with diets that do not include rich sources of this vitamin.

Health benefits of vitamin D

Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, which in turn helps maintain normal bones and teeth. In addition, it contributes to the normal functioning of the immune system and muscles. It also plays a role in the process of cell division.

These benefits are recognized by the European Food Safety Authority (EFSA). It is important to note that vitamin D does not prevent or treat diseases, but rather supports normal physiological processes.

How much vitamin D do you need? Recommended dose

Daily vitamin D needs vary according to age, lifestyle and sun exposure. In the European Union, the reference intake for adults is 200 IU (5 µg) per day, although many organizations recommend higher doses to maintain optimal levels. Priority One Sun D3 provides 3000 IU per capsule, an adequate amount for people who need additional intake.

The EFSA has established a tolerable upper intake level (UL) of 4000 IU (100 µg) per day for adults. Doses above this should be taken under medical supervision. For safe use, it is recommended to follow the manufacturer's instructions or consult a healthcare professional.

Differences between vitamin D2 and D3

There are two main forms of vitamin D in supplements: D2 (ergocalciferol) and D3 (cholecalciferol). D2 is obtained from plant sources, while D3 is usually derived from lanolin (sheep's wool fat) or from lichens for vegan versions. Vitamin D3 is the form that the body produces naturally, and numerous studies indicate that it is more effective in raising and maintaining blood vitamin D levels.

Priority One Sun D3 uses cholecalciferol from lanolin, ensuring high bioavailability. In addition, the capsules are vegetarian (hypromellose), suitable for vegetarian diets.
