MAJOR Vitamina D3 10mcg (400 IU) with Calcium - 100 Tablets

What is vitamin D and why is it important?

Vitamin D is an essential nutrient that plays a key role in numerous bodily functions. Known as the 'sunshine vitamin,' it is synthesized in the skin after exposure to sunlight, but in countries like Spain, during the winter months, or for people with little sun exposure, it can be difficult to get enough. This vitamin D3 (cholecalciferol) supplement from MAJOR provides 10 mcg (400 IU) per tablet, the recommended daily dose for adults, along with 25 mg of calcium to complement its action.

Health benefits of vitamin D

Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, which helps maintain normal bones and teeth. It also contributes to the maintenance of normal blood calcium levels, normal muscle function, and normal immune system function. These benefits are supported by the European Food Safety Authority (EFSA).

How much vitamin D do you need? Recommended dosage

The recommended daily intake for adults in the European Union is 5 mcg (200 IU) to 15 mcg (600 IU), although many experts suggest 400 IU (10 mcg) as the optimal dose for the general population. This supplement provides exactly 400 IU per tablet, an adequate amount to cover daily needs. It is recommended to take one tablet daily, preferably with a meal. If you are taking other supplements or medications, consult your healthcare professional.

Differences between vitamin D2 and D3

There are two main forms of vitamin D: D2 (ergocalciferol) and D3 (cholecalciferol). Vitamin D3 is the form that the human body produces naturally and is considered more effective at increasing and maintaining blood vitamin D levels. D2 comes from plant sources, but its bioavailability is lower. This product contains vitamin D3 (cholecalciferol), the form closest to what the body produces.

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 dosage, the quality of the product, and the absence of allergens. MAJOR tablets are formulated without gluten, yeast, lactose, or artificial colors or flavors. Each tablet contains 25 mg of calcium (as calcium carbonate) and 10 mcg of vitamin D3, making them a complete option for bone and immune maintenance. The MAJOR Pharmaceuticals brand maintains high quality standards through regulatory compliance.

Possible side effects and precautions

Vitamin D is safe when taken at recommended doses. Excessive doses (above 100 mcg/day) can lead to toxicity, so the recommended dose should not be exceeded. This product is indicated for adults. If you are pregnant, breastfeeding, or have any medical condition, consult your doctor before use.
