NOW Foods Vitamina D-3 400 UI Cápsulas blandas, paquete de 2 (360 cápsulas)

What is vitamin D3 and why is it essential?

Vitamin D is a fat-soluble nutrient that plays a fundamental role in numerous bodily functions. It is mainly obtained through sun exposure and, to a lesser extent, from some foods. However, due to factors such as lifestyle, the use of sunscreens, and geographical latitude, many people do not reach optimal levels. NOW Foods offers vitamin D3 in softgel form with 400 IU per capsule, an adequate dose for daily maintenance. This pack of 2 containers with 180 capsules each provides a total of 360 doses, facilitating continuous supplementation.

Benefits of vitamin D according to EFSA

The European Food Safety Authority (EFSA) has approved several health claims for vitamin D. Among them, it highlights that vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, which is essential for the maintenance of normal bones and teeth. It also contributes to the normal functioning of muscles and the immune system. It is important to note that these benefits are based on adequate consumption within a balanced diet. Vitamin D should not be used as a substitute for a varied diet.

How much vitamin D do you need? Recommended dosage

The recommended daily dose 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 µg) per day, although many health authorities suggest up to 400-800 IU to maintain adequate levels. NOW Foods Vitamin D3 provides 400 IU per capsule, an ideal dose for most people as a supplement to a normal diet. It should be remembered that the maximum tolerable intake level (UL) established by EFSA for adults is 4000 IU per day, so 400 IU is considered a safe and effective amount for daily use. It is always advisable to consult a healthcare professional before starting any supplementation.

Differences between vitamin D2 and D3

Vitamin D comes in two main forms: D2 (ergocalciferol) and D3 (cholecalciferol). D2 is obtained from plant sources, such as mushrooms exposed to UV light, while D3 is the form that human skin produces when exposed to the sun and is found in animal products. Various studies suggest that D3 is more effective in raising and maintaining blood vitamin D levels. NOW Foods uses vitamin D3, the most bioavailable form and similar to what our body produces naturally. This ensures better absorption and utilization by the body.

How to choose the best vitamin D supplement

When selecting a supplement, it is important to consider several factors. The form of the vitamin, the dosage, and the quality of the product are key. NOW Foods Vitamin D3 is presented in softgels, an easy-to-swallow and highly absorbable form. In addition, it is a non-GMO, soy-free product, and Halal and Kosher certified (contains gelatin). The company, family-owned and operating since 1968, follows strict quality controls with GMP (Good Manufacturing Practices) certification, which guarantees the purity, potency, and stability of the product. This pack of 2 offers excellent value for money and convenience.

Possible side effects and contraindications

Vitamin D in usual doses is safe and well tolerated. However, excessive consumption (above 4000 IU per day for prolonged periods) can cause toxicity, manifested by hypercalcemia. Symptoms include nausea, weakness, and kidney problems. Therefore, it is recommended not to exceed the indicated doses and to consult a doctor in case of pre-existing conditions or use of medications. This product is a food supplement and should not be used as a substitute for a balanced diet.
