Natural Factors - Vitamin D3 2000 IU, 90 tablets

What is vitamin D3 and why is it essential?

Vitamin D is a fat-soluble nutrient that plays key roles in the body. Although we can synthesize it through sun exposure, in countries like Spain, especially during the winter months, skin production decreases significantly. For this reason, vitamin D supplements have become a practical tool for maintaining adequate levels.

Vitamin D3, also known as cholecalciferol, is the form closest to what our skin produces. Natural Factors presents this supplement in 2000 IU tablets, a dose designed to contribute to daily health. Each container holds 90 tablets, enough for three months if taken once a day.

Made with non-GMO ingredients from organic farms, this product reflects the brand's commitment to quality and sustainability.

Health benefits of vitamin D3

Vitamin D3 contributes to multiple physiological functions supported by the European Food Safety Authority (EFSA). Among the most notable benefits are:

• Normal absorption of calcium and phosphorus: Vitamin D facilitates the assimilation of these minerals, essential for bone structure.
• Maintenance of normal bones: An adequate supply of vitamin D helps maintain bone density and strength.
• Maintenance of normal teeth: Along with calcium, it contributes to dental health.
• Normal muscle function: Sufficient levels of vitamin D promote muscle performance and strength.
• Normal functioning of the immune system: Vitamin D participates in the regulation of the body's natural defenses.

These effects make vitamin D3 an ally for people with limited sun exposure, older adults, or those looking to maintain an active and healthy lifestyle.

How much vitamin D3 do you need? Recommended dose

The optimal amount of vitamin D varies depending on age, sun exposure, and other individual factors. With 2000 IU per tablet, this supplement offers an intermediate dose, suitable for most adults as a complement to diet and sunlight.

It is recommended to take one tablet daily, preferably with a meal to improve its absorption as it is fat-soluble. If you have questions about the most appropriate dose for your case, consult a healthcare professional. Remember that food supplements do not replace a balanced and varied diet.

Differences between vitamin D2 and D3

There are two main forms of vitamin D in supplements: D2 (ergocalciferol) and D3 (cholecalciferol). Vitamin D2 is obtained from plant sources, while D3 comes from lanolin (found in sheep's wool) or from lichens in vegan versions.

Studies indicate that vitamin D3 is more effective at raising and maintaining blood levels of 25-hydroxyvitamin D, the circulating form measured in analyses. For this reason, most experts prefer D3. Natural Factors uses cholecalciferol, the form the body recognizes and uses more easily.

How to choose the best vitamin D3 supplement

When selecting a vitamin D3 supplement, it is advisable to look at the quality of the ingredients and the transparency of the manufacturer. Natural Factors stands out for controlling the entire process: from its own certified organic farms to extraction, encapsulation, and analysis in its own laboratories. This guarantees a product free of pesticides and chemical fertilizers, and free of genetically modified organisms.

In addition, the tablet format facilitates dosing and is suitable for those who prefer to avoid gelatin capsules. The absence of unnecessary additives and the commitment to sustainability (local crops, emission reduction) add value to this choice.

Possible side effects and contraindications

Vitamin D3 is safe at recommended doses. However, excessively high doses (more than 4000 IU per day for prolonged periods) can cause hypercalcemia. If you are pregnant, breastfeeding, or taking medication, consult your doctor before starting the supplement. Keep the product out of the reach of children and do not exceed the indicated daily dose.
