Dr. Dzugan's Advanced Vitamin D3 Formula – 90 Softgels de 5.000 UI

What is vitamin D and why is it important?

Vitamin D is an essential nutrient that the body produces when the skin is exposed to sunlight. However, factors such as indoor lifestyle, sunscreen use, and geographical latitude can limit natural synthesis. This deficiency is especially common in Spain during the winter months. Vitamin D3 (cholecalciferol) is the most bioavailable form and the one the body uses most efficiently. Dr. Dzugan's Advanced Vitamin D3 Formula supplement provides 5,000 IU per softgel, helping to maintain optimal levels when sun exposure is insufficient.

Health benefits of vitamin D

Vitamin D plays a fundamental role in multiple bodily functions. According to the European Food Safety Authority (EFSA), vitamin D contributes to:

• The normal absorption and utilization of calcium and phosphorus.
• The maintenance of normal blood calcium levels.
• The maintenance of normal bones.
• Normal muscle function.
• Normal immune system function.

These benefits support bone health and immune function, key aspects for overall well-being.

How much vitamin D do you need? Recommended dosage

Daily vitamin D needs vary according to age, sex, and sun exposure. EFSA establishes an adequate intake of 15 µg (600 IU) for adults, increasing to 20 µg (800 IU) for those over 70. The tolerable upper limit (UL) for adults is 100 µg (4,000 IU) per day. This supplement offers 5,000 IU per capsule, a high dose that may be suitable for people with confirmed deficiency or increased needs, but it is recommended to consult a healthcare professional before exceeding 4,000 IU daily.

Differences between vitamin D2 and D3

There are two main forms of vitamin D: D2 (ergocalciferol), of plant origin, and D3 (cholecalciferol), of animal origin (generally lanolin). Vitamin D3 is the form that the human body produces naturally and is considered 20% to 50% more effective at raising and maintaining blood vitamin D levels. Dr. Dzugan's Advanced Vitamin D3 Formula contains cholecalciferol, offering the most physiological and efficient form.

How to choose the best vitamin D supplement

When selecting a vitamin D supplement, it is important to consider the dose, the form (D2 vs D3), the source, quality certifications, and the manufacturer's reputation. This product stands out for:

• 5,000 IU per softgel: optimal dose for people with high needs.
• Non-GMO and gluten-free: suitable for special diets.
• GMP certified: manufactured under strict quality controls.
• Formulated by Dr. Dzugan: recognized expert in the field of supplements.

In addition, the softgel presentation facilitates administration and absorption.

Possible side effects and contraindications

Vitamin D is generally safe when taken within recommended doses. Very high doses (>10,000 IU daily for prolonged periods) can lead to toxicity, with symptoms such as nausea, weakness, and kidney stones. People with conditions such as sarcoidosis, hypercalcemia, or kidney disease should consult their doctor before taking supplements. This product is a food supplement and should not be used as a substitute for a balanced diet.
