Unlike other vitamins, it can be synthesized in the skin with sun exposure, but in regions like Spain, especially during winter, production is insufficient. Therefore, food supplements such as \u003cstrong\u003eKirkman's Vitamin D-3 400 IU\u003c\/strong\u003e help meet daily needs. Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, key elements for bone health. In addition, it plays a role in maintaining normal blood calcium levels and in the normal functioning of muscles and the immune system.\u003c\/p\u003e\u003ch2\u003eBenefits of vitamin D for health\u003c\/h2\u003e\u003cp\u003eVitamin D, backed by the European Food Safety Authority (EFSA), offers several health benefits.

Vitamin D is also involved in the cell division process. It is important to remember that vitamin D is fat-soluble, so it is best absorbed when taken with fatty foods.\u003c\/p\u003e\u003ch2\u003eHow much vitamin D do you need? Recommended dose\u003c\/h2\u003e\u003cp\u003eThe recommended daily dose of vitamin D varies according to age, sun exposure and health status. In the European Union, the reference intake for adults is 5 µg (200 IU) per day, although many authorities recommend higher amounts, between 400 and 800 IU per day, especially for people with little sun exposure. \u003cstrong\u003eKirkman's Vitamin D-3 400 IU\u003c\/strong\u003e provides 400 IU per capsule, an ideal dose for daily maintenance. For people with a diagnosed deficiency, healthcare professionals may recommend higher doses. However, the maximum tolerable level of 4000 IU per day should not be exceeded without medical supervision. This product contains 120 capsules, enough for four months if one capsule is taken daily.\u003c\/p\u003e\u003ch2\u003eDifferences between vitamin D2 and D3\u003c\/h2\u003e\u003cp\u003eThere are two main forms of vitamin D: D2 (ergocalciferol) and D3 (cholecalciferol). Vitamin D2 is obtained from plant sources, such as mushrooms exposed to UV light, while D3 is produced in animal skin and found in foods such as fatty fish and cod liver oil. Research suggests that vitamin D3 is more effective at raising and maintaining blood levels of 25-hydroxyvitamin D compared to D2. For this reason, most modern supplements contain D3, as is the case with \u003cstrong\u003eKirkman's Vitamin D-3\u003c\/strong\u003e. When choosing a supplement, it is advisable to opt for D3 for better bioavailability.\u003c\/p\u003e\u003ch2\u003eHow to choose the best vitamin D supplement\u003c\/h2\u003e\u003cp\u003eWhen selecting a vitamin D supplement, it is important to consider the form (D3 over D2), dose, source, and quality of the product. \u003cstrong\u003eKirkman's Vitamin D-3 400 IU\u003c\/strong\u003e stands out for being hypoallergenic, gluten-free and casein-free, and with plant-based capsules, making it suitable for people with food sensitivities. In addition, Kirkman performs extensive \"Ultra Tested\" tests to guarantee the purity and potency of the product. The capsule presentation facilitates dosing and avoids the unpleasant taste that drops sometimes have. It is important to store the capsules in a cool, dry place, protected from light and excessive heat.\u003c\/p\u003e\u003ch2\u003ePossible side effects and contraindications\u003c\/h2\u003e\u003cp\u003eVitamin D is safe when consumed in recommended doses. However, excessive doses (generally \u0026gt;4000 IU per day for prolonged periods) can cause toxicity, manifesting as hypercalcemia (elevated calcium levels in the blood) which can lead to nausea, weakness, and kidney problems. People with certain medical conditions, such as sarcoidosis or hyperparathyroidism, should consult their doctor before taking vitamin D supplements. This product is designed for adults and should not be used as a substitute for a balanced diet. Keep out of reach of young children. Do not exceed the recommended daily dose.\u003c\/p\u003e","brand":"Kirkman","offers":[{"title":"Default Title","offer_id":48764757803162,"sku":null,"price":33.35,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0761\/4831\/0170\/files\/71phNJI1lyL._AC_SL1500.jpg?v=1784483213","url":"https:\/\/vitaminaspain.es\/es\/products\/vitamina-d3-400-ui-capsulas-kirkman-b00p8dvoya","provider":"vitaminaspain","version":"1.0","type":"link"}
