Calculadora de vitamina D
La vitamina D favorece la salud ósea y la inmunidad. La orientación general es de 400 IU/días para bebés, 600 IU/días para niños y adultos, y 800 IU/días para mayores de 70 años. La luz solar, el pescado graso y los alimentos enriquecidos son las principales fuentes; los suplementos ayudan cuando la exposición al sol es baja.
Preguntas frecuentes
- How much vitamin D do I need per day?
- Most adults need about 600 IU (15 mcg) of vitamin D daily, rising to 800 IU (20 mcg) after age 70. This calculator tailors the recommendation to your age and status and reports it in both international units and micrograms.
- What is the safe upper limit for vitamin D?
- For most adults the tolerable upper intake level is 4,000 IU (100 mcg) per day from supplements; routinely exceeding it raises the risk of toxicity. The calculator shows this ceiling so you can supplement safely without going over.
- How can I get more vitamin D naturally?
- Sunlight on bare skin is the main source, supported by foods like oily fish, egg yolks and fortified milk or cereal. Because sun exposure varies with season, latitude and skin tone, many people in winter rely on diet or a supplement to meet their needs.
