Nature Made Vitamina D3 5000 UI Cápsulas Blandas Líquidas, 90 unidades (Paquete de 2)

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, during the winter months or in people with little sun exposure, skin synthesis may be insufficient. Therefore, food supplements such as vitamin D3 capsules become a useful tool to maintain adequate levels.

This fat-soluble vitamin contributes to the normal absorption and utilisation of calcium and phosphorus, fundamental elements for bone health. In addition, it participates in maintaining normal blood calcium levels and in the normal functioning of the immune and muscular systems. The product we present, Nature Made Vitamin D3 5000 IU, provides a high dose of cholecalciferol (vitamin D3) in liquid softgel format, facilitating its intake and absorption.

Health benefits of vitamin D

The benefits of vitamin D are supported by the European Food Safety Authority (EFSA), which has approved several health claims. These include:

• Vitamin D 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 normal muscle function.
• Contributes to the normal functioning of the immune system.

In addition, vitamin D plays a role in the cell division process. These effects make adequate vitamin D intake especially important for bone health and defence against external aggressions. Consumption of 5000 IU of vitamin D3 daily can help maintain optimal levels, especially in people with diagnosed deficiency or risk factors.

How much vitamin D do you need? Recommended dosage

Daily vitamin D recommendations vary according to age, sex and physiological situation. In Spain, the recommended intake for adults is 600 IU (15 mcg) per day, increasing to 800 IU (20 mcg) in people over 70 years of age. However, many experts suggest that these amounts may be insufficient to maintain optimal blood levels, especially in climates with low solar radiation.

This product offers 5000 IU (125 mcg) per capsule, a dose considered high. According to the EFSA, the maximum tolerable intake level (UL) for adults is 4000 IU (100 mcg) per day, from all sources. Therefore, the 5000 IU dose exceeds the established UL. This means that its use should be under medical supervision, especially if combined with other supplements or fortified foods. People with a need for high doses (e.g., due to diagnosed deficiency) may benefit, but always with professional control.

Differences between vitamin D2 and D3

There are two main forms of vitamin D in supplements: vitamin D2 (ergocalciferol), of plant origin, and vitamin D3 (cholecalciferol), which is the form produced by the human body after sun exposure and the one found in foods of animal origin. Vitamin D3 is considered more effective in raising and maintaining blood vitamin D levels, so it is the preferred form in most supplements.

Nature Made uses cholecalciferol (D3) obtained from lanolin, a natural fat found in sheep's wool. This ensures high bioavailability and similarity to the vitamin D that our skin synthesises. Although there are vegan versions of D3 obtained from lichen, lanolin D3 is the most common and studied.

How to choose the best vitamin D supplement

When selecting a vitamin D supplement, there are several factors to consider:

• Vitamin D form: Choose D3 (cholecalciferol) over D2, for its greater efficacy.
• Dosage: Appropriate to your needs and, in high doses, under medical supervision.
• Format: Liquid softgels facilitate absorption, especially in people with difficult digestion.
• Certifications: Although this product does not specify certifications, look for quality seals such as GMP or non-GMO if they are important to you.
• Value for money: Economy packs, such as this one with 2 bottles, offer a prolonged supply.

This Nature Made product meets high manufacturing and purity standards, making it a reliable option for those who need an extra boost of vitamin D.

Possible side effects and contraindications

In adequate doses, vitamin D is safe and well tolerated. However, excessive intake (generally above 10,000 IU per day for a prolonged period) can lead to toxicity, with symptoms such as hypercalcemia, nausea, weakness and kidney problems. Since this product provides 5000 IU, it is recommended not to exceed the indicated daily dose without medical advice. People with conditions such as sarcoidosis, hyperparathyroidism or kidney stones should consult their doctor before taking high doses. In addition, pregnant or breastfeeding women should adjust the dose under supervision.

This product is a food supplement and should not be used as a substitute for a balanced diet. Store in a cool, dry place, out of reach of children.
