Natural Factors Vitamina D3 1000 UI (25 mcg) - 180 Comprimidos

What is vitamin D and why is it important?

Vitamin D is an essential nutrient that plays a fundamental role in multiple bodily functions. Also known as the "sunshine vitamin," it is produced in the skin after exposure to sunlight, but during the autumn and winter months, or in people with little sun exposure, it can be difficult to get enough through the sun alone.

Natural Factors Vitamin D3 1000 IU (25 mcg) provides cholecalciferol, the most bioavailable form of vitamin D, in a convenient daily tablet. Each pack contains 180 tablets, enough for six months of use.

Health benefits of vitamin D

Vitamin D contributes to several processes essential for overall well-being. According to the statements authorized by the European Food Safety Authority (EFSA), vitamin D:

• Contributes to the normal absorption and utilization of calcium and phosphorus.
• Contributes to the maintenance of normal bones.
• Contributes to the maintenance of normal teeth.
• Contributes to the normal functioning of muscles.
• Contributes to the normal functioning of the immune system.

In addition, vitamin D plays a role in the process of cell division. Adequate intake is especially important for maintaining bone health throughout life.

How much vitamin D do you need? Recommended dose

The recommended daily amount of vitamin D varies according to age, sun exposure, and individual needs. For adults, the reference intake in the European Union is 200 IU (5 mcg) per day, although many health organizations suggest higher amounts to maintain optimal levels, especially in populations with low sun exposure.

Each Natural Factors tablet provides 1000 IU (25 mcg) of vitamin D3, a dose that can help meet the daily needs of most people. It is recommended to take one tablet daily, preferably with a meal containing some fat to facilitate absorption. If you have doubts about the appropriate dose for you, consult a healthcare professional.

Differences between vitamin D2 and D3

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

Numerous studies indicate that vitamin D3 is more effective at raising and maintaining blood levels of vitamin D compared to D2. For this reason, most experts recommend opting for D3 supplements. Natural Factors uses high-quality vitamin D3 to ensure maximum effectiveness.

How to choose the best vitamin D supplement

When choosing a vitamin D supplement, it is important to consider the form (D3 versus D2), the dose, and the quality of the product. Natural Factors Vitamin D3 1000 IU undergoes rigorous quality controls: it is third-party certified, contains no genetically modified organisms (non-GMO), and is independently tested for more than 700 contaminants using advanced technologies such as mass spectrometry. This ensures purity and potency in every batch.

In addition, the tablets are easy to swallow and are formulated to offer optimal consistency. Store the product in a cool, dry place, out of reach of children.

Possible side effects and contraindications

Vitamin D3 in doses of up to 1000 IU per day is generally safe and well tolerated. However, excessively high doses (more than 4000 IU per day for prolonged periods) can cause vitamin D toxicity, with symptoms such as nausea, weakness, or kidney problems. If you are taking other medications or have any health condition, consult your doctor before starting supplementation.
