Natural Factors, Vitamin D3 400 IU, Supports Strong Bones and Teeth and Immune Function, 100 Chewable Tablets

What is vitamin D and why is it important?

Vitamin D is an essential nutrient that plays a key role in multiple bodily functions. Known as the "sunshine vitamin," it is produced in the skin after exposure to sunlight, but in many regions, especially during winter, natural synthesis is insufficient. Therefore, vitamin D food supplements are a practical way to maintain adequate levels.

Vitamin D3 (cholecalciferol) is the most bioavailable form, identical to what our body generates. This presentation in 400 IU chewable tablets is ideal for children and adults looking for a gentle and easy-to-take supplement.

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.
• Maintenance of normal teeth.
• Normal muscle function.
• Normal function of the immune system.

In addition, vitamin D plays a role in the process of cell division. These benefits are supported by broad scientific consensus and by European health authorities.

How much vitamin D do you need? Recommended dosage

Each Natural Factors chewable tablet provides 400 IU of vitamin D3, an adequate dose for general health maintenance. For children, this amount usually covers the recommended daily needs, always as part of a balanced diet.

It is important to consult a healthcare professional before starting supplementation, especially in cases of diagnosed deficiency or specific needs. The recommended daily dose should not be exceeded without medical supervision.

Differences between vitamin D2 and D3

Vitamin D can occur in two main forms: D2 (ergocalciferol) and D3 (cholecalciferol). Vitamin D3 is the form that the body naturally produces after sun exposure and is considered more effective in raising and maintaining blood vitamin D levels. For its part, vitamin D2 is of plant origin, but its bioavailability is lower.

This product uses vitamin D3 (cholecalciferol), the form most recommended by nutrition experts.

When selecting a vitamin D supplement, several aspects should be considered:

• Form: D3 is preferable to D2 due to its greater effectiveness.
