21st Century Vitamina D3 5000 UI, 360 Tabletas

What is vitamin D and why is it important?

Vitamin D is an essential nutrient that the body produces when exposed to sunlight, although it is also found in foods such as fatty fish and egg yolks. However, many people do not get enough, especially in winter or with little sun exposure. This 21st Century vitamin D3 (cholecalciferol) supplement offers a convenient way to meet your daily needs, with 5000 IU per tablet and 360 doses per container. Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, the maintenance of normal bones, and the normal functioning of the immune system.

Health benefits of vitamin D

According to the European Food Safety Authority (EFSA), vitamin D plays several key roles in the body. It helps maintain normal blood calcium levels, which is essential for bone health. It also supports the normal functioning of muscles and the immune system. In addition, it plays a role in cell division. These benefits are backed by science and officially recognized. Therefore, an adequate intake of vitamin D is important for people of all ages, especially for those with little sun exposure, over 50 years old or with restrictive diets.

How much vitamin D do you need? Recommended dose

The recommended daily dose of vitamin D varies depending on age and personal circumstances. In general, it is between 400 and 800 IU for most adults, but many people require higher doses to maintain optimal levels. Each 21st Century D3 tablet provides 5000 IU, a high dose that may be appropriate under professional supervision. Since it exceeds the usual recommended daily intake, it is advisable to consult a doctor or pharmacist before starting supplementation. Store the product in a cool, dry place, out of the reach of children.

Differences between vitamin D2 and D3

There are two main forms of vitamin D: D2 (ergocalciferol), of plant origin, and D3 (cholecalciferol), which is the form that the human body produces and is found in animal sources. D3 is more effective in raising and maintaining vitamin D levels in the blood. This product uses vitamin D3, which makes it especially bioavailable. If you follow a vegan diet, keep in mind that D3 is usually obtained from lanolin (sheep's wool fat). Always verify the source if you prefer a plant-based option, although in this case its origin is not specified.

How to choose the best vitamin D supplement

When choosing a vitamin D supplement, consider the form (D3 is preferable), the dose, product quality, and certifications. 21st Century D3 tablets are gluten-free, contain no genetically modified organisms (GMOs), and have no added yeast or artificial flavors.

However, excessively high doses (more than 4000 IU per day for prolonged periods) can lead to toxicity, with symptoms such as nausea, weakness, or kidney problems. Therefore, it is not recommended to exceed the indicated dose without medical advice.
