It is mainly obtained through sun exposure, although it is also present in some foods such as fatty fish, eggs, and fortified dairy products. However, in countries like Spain, during the winter months, sunlight is insufficient, which can lead to low levels of this vitamin. Therefore, supplementation becomes a practical option to maintain adequate levels.\u003c\/p\u003e\u003cp\u003eVitamin D contributes to the normal absorption and utilization of calcium and phosphorus, key elements for bone health. In addition, it helps maintain normal blood calcium levels and participates in the normal functioning of muscles and the immune system.\u003c\/p\u003e\u003ch2\u003eBenefits of vitamin D for health\u003c\/h2\u003e\u003cp\u003eAccording to the European Food Safety Authority (EFSA), vitamin D plays several important functions in the body.

Recommended dose\u003c\/h2\u003e\u003cp\u003eVitamin D needs vary according to age, lifestyle, and sun exposure. EFSA establishes an adequate intake (AI) of 15 µg per day (600 IU) for adults and children from 1 year of age. For those over 70, 20 µg (800 IU) per day is recommended. During pregnancy and lactation, 15 µg daily is also advised.\u003c\/p\u003e\u003cp\u003eEach \u003cstrong\u003eNature's Blend Vitamin D\u003c\/strong\u003e tablet provides 400 IU (10 µg), which is approximately two-thirds of the recommended daily intake for adults. This dose is ideal for maintenance or to supplement a varied diet. If you have a diagnosed deficiency or special needs, consult a healthcare professional to adjust the dose.\u003c\/p\u003e\u003cp\u003eThe maximum tolerable intake (UL) established by EFSA is 100 µg (4000 IU) per day for adults. At 400 IU per tablet, this supplement is within safe limits, even if combined with other sources of vitamin D.\u003c\/p\u003e\u003ch2\u003eDifferences between vitamin D2 and D3\u003c\/h2\u003e\u003cp\u003eThere are two main forms of vitamin D in supplements: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). D2 is obtained from plant sources, such as mushrooms exposed to UV radiation, while D3 is usually derived from lanolin (sheep's wool fat) or lichen (suitable for vegans).\u003c\/p\u003e\u003cp\u003eStudies indicate that vitamin D3 is more effective at raising and maintaining blood vitamin D levels. However, both forms contribute to the same health benefits. This supplement contains vitamin D without specifying the specific form; check the product label for detailed information on its origin.\u003c\/p\u003e\u003ch2\u003eHow to choose the best vitamin D supplement\u003c\/h2\u003e\u003cp\u003eWhen selecting a vitamin D supplement, consider the following aspects:\u003c\/p\u003e\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eDosage:\u003c\/strong\u003e 400 IU is an adequate dose for daily maintenance.
