NOW Foods Vitamina D-2 1000 UI Alta Potencia - 120 Cápsulas Vegetales, Paquete de 3

What is vitamin D and why is it important?

Vitamin D is a fat-soluble nutrient essential for the body. It is synthesized in the skin after exposure to sunlight, but factors such as latitude (especially in Spain during winter), the use of sunscreens, and an urban lifestyle limit its production. Vitamin D deficiency is common and is associated with bone and muscle problems. There are two main forms: vitamin D2 (ergocalciferol), of plant origin, and vitamin D3 (cholecalciferol), of animal origin. NOW Foods Vitamin D-2 1000 IU provides ergocalciferol in vegetable capsules, ideal for vegans and vegetarians. Each capsule provides 1000 IU, a high dose that helps maintain adequate levels.

Health benefits of vitamin D

Benefits supported by EFSA

The European Food Safety Authority (EFSA) has approved several health claims for vitamin D. These include:

• Contributes to the normal absorption and utilization of calcium and phosphorus.
• Contributes to the maintenance of normal blood calcium levels.
• Contributes to the maintenance of normal bones.
• Contributes to the maintenance of normal teeth.
• Contributes to normal muscle function.
• Contributes to the normal function of the immune system.
• Contributes to the process of cell division.

Therefore, a vitamin D supplement like NOW Foods can be an important ally in preserving bone, muscle, and immune health, especially when sun exposure is insufficient.

How much vitamin D do you need? Recommended dosage

Vitamin D intake recommendations vary by age and situation. For healthy adults, the recommended daily intake (RDI) in Europe is 200 IU (5 µg), but many authorities suggest higher doses (600-800 IU) to maintain optimal levels. Older people, those with dark skin, obesity, or low sun exposure may need higher doses. This product offers 1000 IU per capsule, which may be adequate to cover the daily needs of those with a deficiency or at risk of deficiency. It is recommended to take one capsule daily with food. Each pack includes 3 bottles of 120 capsules, totaling 360 capsules, enough for approximately one year of daily supplementation. It is always wise to consult a healthcare professional to adjust the dose to your individual needs.

Differences between vitamin D2 and D3

Vitamin D2 (ergocalciferol) is obtained from plant sources such as yeasts and fungi exposed to ultraviolet radiation. Vitamin D3 (cholecalciferol) is produced from lanolin (sheep wool fat) or fish oil. Both forms are converted to the active form in the liver and kidneys. Although some studies indicate that D3 may raise blood levels of 25-hydroxyvitamin D more effectively, D2 remains a valid option and is the only plant-based form available. NOW Foods Vitamin D-2 is an excellent choice for those seeking a 100% plant-based supplement. In addition, the capsules are of plant origin, suitable for vegans.

Possible side effects and contraindications

Vitamin D is safe at recommended doses. Excessive intake (toxicity) is rare but possible with very high doses (>4000 IU/day for months). Symptoms include hypercalcemia, nausea, and weakness. This product provides 1000 IU per capsule, within safe limits. However, people with sarcoidosis, hyperparathyroidism, or kidney stones should consult their doctor.
