Often called the \"sunshine vitamin,\" it is produced in the skin after exposure to sunlight. However, in Spain, especially during the winter months, sun exposure is limited, making supplementation a convenient option to maintain adequate levels. Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, which is essential for bone health. It also plays a role in the normal functioning of the immune system and muscles.\u003c\/p\u003e\u003cp\u003eKirkland Extra Strength Vitamin D-3 provides 2000 IU of cholecalciferol (vitamin D3) per softgel, in a pack of 600 capsules. It is a high-strength formula, ideal for those seeking extra support throughout the year. Additionally, it is USP verified, ensuring its quality and purity.\u003c\/p\u003e\u003ch2\u003eHealth benefits of vitamin D\u003c\/h2\u003e\u003cp\u003eAccording to the European Food Safety Authority (EFSA), vitamin D has several scientifically backed benefits:\u003c\/p\u003e\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eCalcium and phosphorus absorption:\u003c\/strong\u003e Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, essential minerals for maintaining strong bones and teeth.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eBone maintenance:\u003c\/strong\u003e It helps maintain normal bone conditions, which is especially important in older adults and people at risk of osteoporosis.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eMuscle function:\u003c\/strong\u003e Contributes to the normal functioning of muscles, which can help prevent falls and improve mobility.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eImmune system:\u003c\/strong\u003e Vitamin D contributes to the normal functioning of the immune system, helping the body's defenses.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eBlood calcium levels:\u003c\/strong\u003e Contributes to the maintenance of normal blood calcium levels.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003cp\u003eThese benefits are endorsed by the EFSA, and Kirkland Extra Strength Vitamin D-3 provides them in a convenient daily dose.\u003c\/p\u003e\u003ch2\u003eHow much vitamin D do you need? Recommended dosage\u003c\/h2\u003e\u003cp\u003eThe recommended daily dose of vitamin D varies depending on age, lifestyle, and sun exposure. For adults, the recommended daily allowance (RDA) in the European Union is 5 µg (200 IU) to 15 µg (600 IU) per day, although many health authorities suggest higher doses for people with low sun exposure or risk factors. The Kirkland product provides 2000 IU (50 µg) per capsule, which is a higher dose than the RDA, but within the upper tolerable limit established by EFSA of 4000 IU (100 µg) per day for adults. It is important not to exceed this dose without medical supervision.\u003c\/p\u003e\u003cp\u003eEach pack contains 600 softgels, which is equivalent to a supply for almost two years if one capsule is taken daily. It is recommended to take one capsule daily with a meal containing some fat to improve absorption.\u003c\/p\u003e\u003ch2\u003eDifferences between vitamin D2 and D3\u003c\/h2\u003e\u003cp\u003eVitamin D comes in two main forms: D2 (ergocalciferol) and D3 (cholecalciferol). Vitamin D3 is the form produced by the human body after sun exposure and is found in animal sources such as fish oil and sheep's wool. Vitamin D2 is obtained from plant sources such as mushrooms exposed to UV rays. Studies suggest that vitamin D3 may be more effective in raising and maintaining serum vitamin D levels in the blood. Kirkland uses vitamin D3 (cholecalciferol) in its softgels, making it an optimal option for supplementation.\u003c\/p\u003e\u003ch2\u003eHow to choose the best vitamin D supplement\u003c\/h2\u003e\u003cp\u003eWhen choosing a vitamin D supplement, it is important to consider the form (D3 vs. D2), the dosage, and the quality of the product. Kirkland Extra Strength Vitamin D-3 is USP verified, meaning it meets rigorous standards for purity, potency, and disintegration. The softgels are easy to swallow and contain oil, which facilitates the absorption of the fat-soluble vitamin. Additionally, the 600-capsule pack offers excellent value for money for long-term use.\u003c\/p\u003e\u003cp\u003eThis product is suitable for adults who wish to maintain optimal vitamin D levels, especially during winter or for people with low sun exposure. As a food supplement, it should not be used as a substitute for a balanced diet.\u003c\/p\u003e\u003ch2\u003ePossible side effects and contraindications\u003c\/h2\u003e\u003cp\u003eVitamin D is generally safe when taken at recommended doses. However, excessively high doses (\u0026gt;4000 IU per day) can cause hypercalcemia (high blood calcium levels), which can lead to nausea, weakness, and kidney problems. It is recommended not to exceed the established daily dose without consulting a healthcare professional. People with certain medical conditions (such as sarcoidosis or hyperparathyroidism) should consult their doctor before taking vitamin D supplements. This product is a food supplement and should not be used as a substitute for a balanced diet.\u003c\/p\u003e","brand":"KIRKLAND","offers":[{"title":"Default Title","offer_id":48764430352538,"sku":null,"price":34.81,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0761\/4831\/0170\/files\/81dr_kdIG4L._AC_SL1500.jpg?v=1784480190","url":"https:\/\/vitaminaspain.es\/es\/products\/kirkland-vitamina-d3-2000-ui-600-softgels-b00jgz63we","provider":"vitaminaspain","version":"1.0","type":"link"}
