Supersmart - Vitamina D3 5000 UI (125mcg) - High Potency and Bioavailability - with Sunflower Oil | Non-GMO and Gluten-Free - 60 Softgels

What is vitamin D and why is it important?

Vitamin D is an essential nutrient that plays a fundamental role in multiple bodily functions. Often called the "sunshine vitamin," our body produces it when the skin is exposed to sunlight. However, during the winter months or in people with low sun exposure, intake through diet or supplements becomes crucial.

Supersmart Vitamin D3 5000 IU offers cholecalciferol (D3), the most bioavailable form of vitamin D, in a high-potency presentation. Each softgel contains 5000 IU (125 mcg) combined with sunflower oil to optimize absorption. This supplement is designed for those who need an additional intake, under professional supervision.

Health benefits of vitamin D

Vitamin D contributes to various physiological processes, supported by the European Food Safety Authority (EFSA). Its functions 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 normal muscle function.
• Contributes to the normal function of the immune system.

In addition, vitamin D plays a role in the process of cell division. These benefits are recognized by the EFSA, which ensures that the claims are scientifically backed.

How much vitamin D do you need? Recommended dose

The recommended daily allowance (RDA) for vitamin D for adults in Europe is 200 IU (5 mcg), although individual needs may vary. To maintain optimal levels, especially in people with deficiency or low sun exposure, higher doses may be necessary.

Supersmart Vitamin D3 provides 5000 IU per capsule, a high dose that covers 2500% of the RDA. This amount is above the tolerable upper intake level established by the EFSA (4000 IU/day for adults). Therefore, its use is recommended only under medical advice, especially if you have kidney disease or are taking other vitamin D supplements. The usual dose is one capsule daily, or as directed by a healthcare professional.

Excessive intake of vitamin D can lead to adverse effects. Consult your doctor before starting high-dose supplementation.

Differences between vitamin D2 and D3

There are two main forms of vitamin D: D2 (ergocalciferol) and D3 (cholecalciferol). Vitamin D2 is obtained from plant sources, while D3 is the form that the human body produces after sun exposure and is also found in animal-derived foods.

Studies suggest that vitamin D3 is more effective in raising and maintaining blood levels of vitamin D compared to D2. Supersmart uses D3 (cholecalciferol), the form closest to what our body produces, which favors its utilization.

Our supplement is vegan and does not contain animal-derived ingredients, as cholecalciferol is obtained from plant sources such as lichen (not from lanolin).

How to choose the best vitamin D supplement

When selecting a vitamin D supplement, consider the following aspects:

• Form: Prefer D3 (cholecalciferol) due to its higher bioavailability.
• Dosage: Choose a dose appropriate for your needs; high doses require medical supervision.
• Source: If you are vegan, look for D3 from lichen, as in this product.
• Certifications: Non-GMO, gluten-free, soy-free, and artificial additive-free products offer higher quality.
• Format: Softgels with oil promote absorption, as vitamin D is fat-soluble.

Supersmart meets all these criteria: it offers pure vitamin D3 with sunflower oil, gluten-free, non-GMO, vegan, and free of preservatives, colorants, and artificial flavors. Since 1992, the brand has been committed to quality and customer satisfaction.

Possible side effects and contraindications

Vitamin D3 is generally safe at recommended doses. However, very high doses (above 4000 IU/day) can lead to hypercalcemia (excess calcium in the blood), with symptoms such as nausea, weakness, or kidney problems. Do not exceed the recommended dose without consulting a professional.

Contraindications: People with kidney disease, sarcoidosis, or hypercalcemia should avoid vitamin D supplementation without medical supervision. If you are pregnant, breastfeeding, or taking other medications, consult your doctor before using this product.
