KAL Vitamina D3 5000 UI (125 mcg) - 90 Cápsulas Blandas - Suplemento Alimenticio

What is vitamin D and why is it important?

Vitamin D is an essential nutrient that plays a key role in numerous bodily functions. Often called the "sunshine vitamin," it is produced in the skin after exposure to sunlight. However, in countries like Spain, especially during the winter months or for people with little sun exposure, it can be difficult to get enough from sunlight alone. Therefore, vitamin D supplements are a practical option to maintain adequate levels. Vitamin D3 (cholecalciferol) is the most bioavailable form and the one the body uses most efficiently.

The KAL Vitamin D3 5000 IU product provides a high dose in a convenient liquid softgel capsule (ActivGel), designed for optimal absorption. Each package contains 90 capsules, enough for 90 days if taken once a day. It is formulated without soy and is suitable for a wide variety of diets.

Health benefits of vitamin D

Vitamin D contributes to various physiological functions supported by the European Food Safety Authority (EFSA). The most notable benefits include:

• Calcium and phosphorus absorption: Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, essential for bone health.
• Bone maintenance: It helps maintain bones in normal conditions, which is especially important in older adults and postmenopausal women.
• Muscle function: Contributes to normal muscle function, reducing the risk of falls in older people.
• Immune system: Vitamin D contributes to the normal functioning of the immune system, helping the body's defenses.
• Blood calcium levels: Contributes to the maintenance of normal blood calcium levels.

These benefits are recognized by European health authorities, so they can be mentioned without making exaggerated claims.

How much vitamin D do you need? Recommended dosage

The recommended daily dose of vitamin D varies depending on age, sex, sun exposure, and health status. For adults, the reference intake is usually 600 to 800 IU per day, although many people require higher doses to reach optimal levels. The KAL product provides 5000 IU per capsule, a high dose that may be suitable for people with diagnosed deficiency or low sun exposure, always under professional supervision.

It is important to consider the tolerable upper limit (UL) established by EFSA, which is 4000 IU per day for adults. Doses greater than 4000 IU should be recommended by a doctor. Therefore, this supplement is intended for people who need a high intake and who have previously consulted with a healthcare professional. It is recommended to take one capsule a day with a meal containing fat to improve absorption.

Differences between vitamin D2 and D3

Vitamin D comes in two main forms: D2 (ergocalciferol) and D3 (cholecalciferol). D2 is obtained from plant sources, such as UV-exposed mushrooms, while D3 is the form produced in human skin and found in animal-derived foods. Numerous studies suggest that vitamin D3 is more effective at raising and maintaining blood vitamin D levels. Therefore, most high-quality supplements, such as KAL's, use D3, which is the active form that the body recognizes and uses most efficiently.

The KAL product uses cholecalciferol of ovine origin (lanolin), guaranteeing a natural and high-purity source. If you are vegan or vegetarian, you should look for D3 supplements of lichen origin, although this product is not vegan.

How to choose the best vitamin D supplement

When selecting a vitamin D supplement, it is important to consider several factors:

• Form of vitamin D: Opt for D3 (cholecalciferol) for its greater bioavailability.
• Dosage: Choose a dose appropriate to your needs. 5000 IU is a high dose, ideal for people with severe deficiency or little sun exposure.
• Format: Liquid softgels (like KAL's ActivGels) favor better absorption.
• Ingredients: Verify that it does not contain allergens such as soy, gluten, or dairy. This product is soy-free.
• Certifications: Look for brands that follow good manufacturing practices (GMP) and are transparent in their labeling.

KAL is a recognized brand in the food supplement sector, with decades of experience and a commitment to quality.

Possible side effects and contraindications

Vitamin D is generally safe when taken within recommended doses. However, extremely high doses (more than 10,000 IU per day for prolonged periods) can lead to toxicity, with symptoms such as nausea, vomiting, loss of appetite, or kidney stones. It is not recommended to exceed 4000 IU daily without medical supervision. This product is indicated for individuals over 18 years of age. Pregnant or breastfeeding women should consult their doctor before use. Store in a cool, dry place, protected from light and heat.

This product is a food supplement, it should not be used as a substitute for a balanced diet. Do not exceed the recommended daily dose. Keep out of reach of children.
