Metabolic Maintenance Vitamina D3 2000 UI - 120 Cápsulas

What is vitamin D3 and why is it important?

Vitamin D3, also known as cholecalciferol, is a form of vitamin D that is produced naturally in the skin after sun exposure. It is essential for numerous bodily functions, especially the absorption of calcium and phosphorus, bone health, and the immune system. In Spain, during the autumn and winter months, sun exposure is limited, so supplementation with vitamin D3 can help maintain adequate levels.

The supplement Metabolic Maintenance Vitamin D3 2000 IU provides 50 mcg of cholecalciferol per capsule, in a bioavailable and high-purity form. It is formulated for adults with low sun exposure who are looking for fundamental nutritional support.

Health benefits of vitamin D3

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

• The normal absorption and utilization of calcium and phosphorus.
• The maintenance of normal blood calcium levels.
• The maintenance of normal bones.
• The normal functioning of muscles.
• The normal functioning of the immune system.

In addition, vitamin D plays a role in the process of cell division. Therefore, maintaining adequate levels is key to overall health.

How much vitamin D3 do you need? Recommended dosage

The dose of vitamin D can vary depending on age, sun exposure, and individual needs. The recommended daily intake in the European Union is 5 µg (200 IU) for adults, although many people require higher doses to maintain optimal levels. The dose of 2000 IU (50 µg) offered by this supplement is within the safe limits established by EFSA, which sets the maximum tolerable level at 100 µg (4000 IU) per day for adults.

It is recommended to take one capsule a day, preferably with a meal containing fat to improve absorption. If you have doubts about the appropriate dose for you, consult a health professional.

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 produced by the human body. Vitamin D3 is more effective at raising and maintaining blood vitamin D levels. Therefore, most high-quality supplements, such as this one from Metabolic Maintenance, use D3.

How to choose the best vitamin D3 supplement

When selecting a vitamin D3 supplement, it is important to consider:

People with certain medical conditions (such as sarcoidosis or hypercalcemia) should consult a doctor before taking vitamin D supplements.
