Vitamina D 400 UI – 90 Tabletas – Laboratorios Jamieson

What is vitamin D and why is it important?

Vitamin D is an essential nutrient that plays a key role in the absorption of calcium and phosphorus, fundamental minerals for bone and teeth health. It is primarily obtained through sun exposure, but in many regions, especially during winter months, skin synthesis is insufficient. Therefore, food supplements such as Jamieson's Vitamin D 400 IU help meet daily needs. This supplement is formulated to provide a moderate dose of vitamin D in convenient tablets, ideal for those looking to maintain adequate levels throughout the year.

In addition to its role in bone metabolism, vitamin D contributes to the normal functioning of the immune system and muscle function. In Spain, the prevalence of vitamin D deficiency is notable, especially in populations with little sun exposure, older people, or those with restrictive diets. Incorporating a supplement like this can be a simple and effective strategy to ensure sufficient intake.

Health benefits of vitamin D

Vitamin D has multiple benefits supported by the European Food Safety Authority (EFSA). Approved health claims include:

• Contributes to the normal absorption and utilisation of calcium and phosphorus.
• Contributes to the maintenance of normal blood calcium levels.
• Contributes to the maintenance of normal bones.
• Contributes to the maintenance of normal teeth.
• Contributes to normal muscle function.
• Contributes to the normal function of the immune system.

These effects make vitamin D an essential nutrient for people of all ages, especially for those at higher risk of deficiency: over 65, pregnant or breastfeeding women, people with dark skin, or those living in northern latitudes. Maintaining adequate vitamin D levels is an important preventive measure for overall health.

How much vitamin D do you need? Recommended dosage

Each tablet of Jamieson Vitamin D provides 400 IU (10 µg) of vitamin D, an adequate dose for general health maintenance. The recommended daily amount may vary depending on age, sun exposure, and individual needs. For the general adult population, the reference intake in the European Union is 200 IU (5 µg) per day, but many experts suggest that higher doses may be beneficial, especially in cases of deficiency.

It is important not to exceed the recommended daily dose without medical supervision. The upper tolerable limit established by the EFSA for adults is 4000 IU (100 µg) per day, although high doses should only be used under prescription. If you have doubts about the appropriate dose for you, consult a healthcare professional. This product is a food supplement and should not be used as a substitute for a balanced diet.

Differences between vitamin D2 and vitamin D3

There are two main forms of vitamin D in supplements: D2 (ergocalciferol) and D3 (cholecalciferol). Vitamin D3 is the form that the body naturally produces when exposed to the sun and is obtained from animal sources such as lanolin. For its part, vitamin D2 is derived from plant sources, such as fungi exposed to UV rays.

How to choose the best vitamin D supplement

When selecting a vitamin D supplement, consider several factors: dosage, form, brand quality, and certifications. This Jamieson Laboratories product offers a dose of 400 IU in tablet form, easy to take. Jamieson is a recognized brand with over 90 years of experience in the health and supplement sector.

To ensure quality, verify that the product has been manufactured under strict quality controls. Also, consider whether you prefer a presentation in drops, softgels, or tablets. Tablets are a practical option for daily use. If you follow a vegan diet, look for supplements with vitamin D2 or plant-based D3 (lichen), although this product may contain D3 from lanolin, so it is advisable to check the label.

Possible side effects and contraindications

Vitamin D is safe when consumed at recommended doses. However, excessively high and prolonged doses can lead to hypercalcemia (high calcium levels in the blood), with symptoms such as nausea, weakness, or kidney problems. Therefore, it is important not to exceed the indicated dose without medical advice. People with certain health conditions, such as sarcoidosis or kidney disorders, should consult their doctor before taking vitamin D supplements. This product is intended for adults and should not be used by children without supervision.

This product is a food supplement and should not be used as a substitute for a balanced diet. Do not exceed the recommended daily dose. Keep out of reach of young children. Consult a healthcare professional before use if you are pregnant, breastfeeding, or have any medical condition.
