NOW Foods Vitamina D3 5000 UI, 360 Cápsulas Blandas

What is Vitamin D and why is it important?

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin essential for the body. Unlike other vitamins, our body can synthesize it through sun exposure. However, factors such as winter, the use of sunscreen or living in northern latitudes can limit this production. Therefore, supplementation with vitamin D3 has become a common practice to maintain adequate levels.

NOW Foods Vitamin D3 5000 IU is a food supplement in softgel capsules that provides a high dose of cholecalciferol, the most bioavailable form of vitamin D. Each capsule offers 5000 IU, which helps meet daily needs, especially in times of less sun exposure.

Benefits of vitamin D for health

Vitamin D plays multiple roles in the body, supported by the European Food Safety Authority (EFSA). Among the most notable benefits are:

• Absorption of calcium and phosphorus: Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, essential minerals for bone health.
• Maintenance of bones and teeth: Helps maintain bones in normal conditions and contributes to the maintenance of healthy teeth.
• Muscle function: Participates in the normal functioning of muscles.
• Immune system: Contributes to the normal functioning of the immune system, helping the body's natural defenses.
• Cell division: Plays a role in the cell division process.

These effects are based on health claims authorized by the EFSA. Vitamin D does not replace a varied diet, but its supplementation can be beneficial when dietary intake or skin synthesis are insufficient.

How much vitamin D do you need? Recommended dose

Daily vitamin D needs vary depending on age, lifestyle and sun exposure. In Spain, the recommended intake for adults is between 600 and 800 IU per day, although many people opt for higher doses to maintain optimal levels.

NOW Foods Vitamin D3 5000 IU provides 125 mcg (5000 IU) per capsule, a high dose. For most healthy adults, this amount is safe when taken daily, but it is recommended not to exceed the tolerable upper limit of 4000 IU per day without medical supervision. Consult your healthcare professional before starting supplementation, especially if you are pregnant, breastfeeding or taking other medications.

This product comes in a batch of 360 capsules (3 bottles of 120), enough for a year of use if one capsule is taken daily.

Differences between vitamin D2 and D3

There are two main forms of vitamin D in supplements: D2 (ergocalciferol) and D3 (cholecalciferol). Vitamin D2 is obtained from plant sources, while D3 is of animal origin (lanolin) or, in its vegan version, from lichens. D3 is the form naturally produced by human skin and is considered more effective in raising and maintaining blood vitamin D levels.

NOW Foods Vitamin D3 5000 IU uses cholecalciferol, the form closest to what the body synthesizes, which ensures optimal absorption and utilization. Although D2 can also be effective, D3 is generally preferred for its greater potency and duration in the body.
