Nutricost Vitamin D3 10,000 IU, 240 Softgels - High Potency, Non-GMO, Gluten Free

What is Vitamin D and why is it important?

Vitamin D is an essential nutrient that plays a crucial role in overall health. It is known as the "sunshine vitamin" because the body produces it when the skin is exposed to sunlight. However, in Spain, during the winter months and in people with little sun exposure, levels can be insufficient. Vitamin D exists in two main forms: D2 (ergocalciferol) and D3 (cholecalciferol). D3 is the most bioavailable form and the one found in this supplement. Nutricost Vitamin D3 provides 10,000 IU per softgel, a potent dose to help maintain optimal levels.

Health Benefits of Vitamin D

Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, which is essential for maintaining normal bones and teeth*. In addition, it contributes to the normal functioning of the immune system* and the maintenance of muscle function*. These benefits are supported by the European Food Safety Authority (EFSA). Each Nutricost Vitamin D3 capsule helps meet daily needs, especially in people with deficiencies.

*Statements are approved by the EFSA.

How much Vitamin D do you need? Recommended dosage

The recommended daily dose varies depending on age, health status, and sun exposure. In adults, the reference intake is 5 µg (200 IU) per day, but many experts suggest higher amounts to maintain optimal blood levels. The tolerable upper limit (UL) established by the EFSA is 100 µg (4,000 IU) per day for adults. This Nutricost supplement provides 10,000 IU per capsule, a high dose that should be taken under medical supervision. It is recommended to consult a healthcare professional before starting supplementation with high doses. For long-term use, perform regular blood tests.

Differences between Vitamin D2 and D3

Vitamin D2 (ergocalciferol) is obtained from plant sources and fungi, while D3 (cholecalciferol) is the form produced by the human body and found in animal-derived foods such as fatty fish and lanolin. Numerous studies indicate that vitamin D3 is more effective at raising and maintaining blood levels of 25-hydroxyvitamin D. Nutricost uses high-quality vitamin D3, ensuring better bioavailability. If you are vegan, look for D3 from lichen; this one comes from lanolin.
