Vitamina D3 1000 IU, 360 Cápsulas Blandas - NOW Foods

What is vitamin D3 and why is it important?

Vitamin D3, also known as cholecalciferol, is a form of vitamin D that the body can use directly. It is naturally produced in the skin after sun exposure, but modern life and reduced sun exposure often make supplementation necessary. NOW Foods offers vitamin D3 in 1000 IU softgels, an adequate dose to maintain optimal levels. This fat-soluble vitamin is essential for multiple functions, from calcium absorption to immune system support.

Health benefits of vitamin D3

Vitamin D3 contributes to various physiological processes supported by the European Food Safety Authority (EFSA):

• Calcium and phosphorus absorption: Helps absorb and utilize these key minerals for bone health.
• Maintenance of normal bones: Promotes bone mineralization and prevents density loss with age.
• Normal muscle function: Participates in muscle contraction and performance.
• Immune system: Supports the body's natural defenses against external aggressions.
• Blood calcium levels: Helps regulate blood calcium concentration, essential for the nervous and cardiac systems.

These effects make vitamin D3 a key supplement for people with low sun exposure, older adults, or those looking to support their general health.

How much vitamin D3 do you need? Recommended dose

Each NOW Foods softgel provides 1000 IU of vitamin D3 (cholecalciferol). This dose is adequate for most adults as a supplement to dietary intake and sun exposure. It is recommended to take one capsule daily, preferably with a meal containing fat to improve its absorption. If you have specific needs or health conditions, consult a healthcare professional to adjust the dose.

Vitamin D is measured in IU (international units). For reference, the recommended daily intake in Europe for adults is 200 IU, although many experts suggest higher amounts, especially in winter or in people with darker skin. Do not exceed the recommended daily dose without supervision.

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. D3 is considered more effective at raising and maintaining blood vitamin D levels. NOW Foods uses D3, the most biologically active and best utilized form by the body. If you are looking for a plant-based supplement, D2 is an option, but D3 is the most recommended due to its greater potency and duration.
