NOW Foods Vitamina D3 1.000 UI Comprimidos Masticables Sabor Frutas Naturales 180 unidades

What is Vitamin D and why is it important?

Vitamin D is a fat-soluble nutrient essential for the body. It is known as the "sunshine vitamin" because the skin produces it when exposed to sunlight. However, in Spain, especially during the autumn and winter months, sun exposure is limited, which means many people have suboptimal levels. This vitamin plays a key role in the normal absorption and utilization of calcium and phosphorus, thus contributing to the maintenance of strong bones. In addition, it is involved in the normal functioning of the immune system and muscles.

NOW Foods presents its vitamin D3 in a practical chewable presentation with natural fruit flavor, ideal for those who prefer to avoid capsules. Each tablet provides 1,000 IU of cholecalciferol (vitamin D3), the most bioavailable form and similar to that generated by the human body.

Health benefits of vitamin D

According to the European Food Safety Authority (EFSA), vitamin D contributes to:

• Normal absorption and utilization of calcium and phosphorus.
• Maintenance of normal blood calcium levels.
• Maintenance of normal bones.
• Normal muscle function.
• Normal immune system function.
• Reducing the risk of falls associated with postural instability and muscle weakness in people over 60 years of age.

In addition, vitamin D is involved in the cell division process. These benefits are recognized by the EFSA and backed by decades of scientific research.

How much vitamin D do you need? Recommended dosage

The recommended daily dose for the general population in Europe is 200 IU (5 µg) for adults, although many experts suggest higher intakes (400-800 IU) to maintain optimal levels, especially in people with low sun exposure. This product provides 1,000 IU per tablet, an amount that falls within the safe range established by EFSA (the tolerable upper limit is 4,000 IU daily for adults).

It is recommended to take one chewable tablet daily, preferably with a meal containing fat to improve its absorption. Do not exceed the recommended daily dose. As with any supplement, consult your healthcare professional before starting, especially if you are pregnant, breastfeeding, or taking medication.

Differences between vitamin D2 and D3

There are two main forms of vitamin D: D2 (ergocalciferol) and D3 (cholecalciferol). D2 is obtained from plant sources, such as UV-exposed mushrooms, while D3 is what human skin produces and is found in animal foods (fatty fish, eggs) or in supplements derived from lanolin (sheep's wool fat). Several studies indicate that D3 is more effective at raising and maintaining serum vitamin D levels in the body. For this reason, NOW Foods uses D3 (cholecalciferol) in its chewable tablets, guaranteeing the most active and usable form.

How to choose the best vitamin D supplement

When selecting a vitamin D supplement, it is important to consider the form (D3 versus D2), the dosage, the presentation, and the quality certificates. This product stands out for several reasons:

• Optimal form: Vitamin D3 (cholecalciferol) for better absorption.
• Chewable format: Easy to take, no water needed, with a pleasant natural fruit flavor.
• Certified quality: Manufactured under strict GMP standards. Its internal laboratories are ISO/IEC accredited for stability, potency, and formulation testing.
• Additional certifications: Kosher, gluten-free, soy-free, and made without animal-derived ingredients (suitable for vegetarian or vegan diets, as lanolin is of sheep origin).
• Track record: NOW Foods is a family-owned company founded in 1968, recognized for its commitment to quality and purity.

In addition, as it is a chewable product, it is ideal for people who have difficulty swallowing capsules or who simply prefer a more pleasant experience.

Possible side effects and contraindications

Vitamin D is generally safe when taken within the recommended doses. However, excessively high doses for prolonged periods (more than 4,000 IU daily in adults) can cause hypercalcemia (excess calcium in the blood), with symptoms such as nausea, weakness, and kidney problems. If you suffer from sarcoidosis, hyperparathyroidism, or kidney disease, consult your doctor before taking vitamin D supplements. This product should not be used as a substitute for a balanced diet or a healthy lifestyle.
