Nutricost Vitamina D3 10,000 UI, 240 Softgels (2 Botellas)

What is vitamin D and why is it important?

Vitamin D is a fat-soluble nutrient essential for multiple bodily functions. It is known as the "sunshine vitamin" because the skin synthesizes it when exposed to sunlight. However, in Spain, during the autumn and winter months, UVB radiation is insufficient to produce adequate amounts, leading many people to resort to supplementation.

The most bioavailable form of vitamin D is D3 or cholecalciferol, identical to what the body generates. This vitamin plays a key role in calcium absorption, bone maintenance, muscle function, and the immune system. Therefore, maintaining optimal levels is fundamental for overall health.

Health benefits of vitamin D

According to the European Food Safety Authority (EFSA), vitamin D contributes to:

• The normal absorption and utilization of calcium and phosphorus.
• The maintenance of normal blood calcium levels.
• The maintenance of bones under normal conditions.
• The normal functioning of muscles.
• The normal functioning of the immune system.

Additionally, vitamin D contributes to the process of cell division. These benefits are backed by science and are part of the community register of authorized claims.

How much vitamin D do you need? Recommended dose

Vitamin D needs vary according to age, sun exposure, and health status. The reference intake for adults in the EU is 5 µg (200 IU) per day, although many experts consider this amount insufficient to maintain optimal levels. The daily dose recommended by some scientific societies ranges between 600 and 2000 IU for healthy adults.

The Nutricost Vitamin D3 supplement provides 10,000 IU (250 µg) per softgel capsule, a high dose indicated for people with diagnosed deficiency or under medical supervision. The EFSA sets a maximum tolerable level (UL) of 4000 IU (100 µg) per day for adults. Therefore, higher doses should only be used under the recommendation of a healthcare professional. It is not recommended to exceed the daily dose indicated on the product.

Differences between vitamin D2 and D3

There are two main forms of vitamin D: D2 (ergocalciferol), of plant origin, and D3 (cholecalciferol), of animal or synthetic origin. D3 is the form the body produces naturally and is considered more effective at raising and maintaining blood vitamin D levels. Numerous studies suggest that D3 has a higher affinity for vitamin D receptors and remains in the bloodstream longer.

The Nutricost product uses pure vitamin D3 (cholecalciferol), obtained from lanolin (sheep's wool fat), which ensures high bioavailability and efficacy.
