Health benefits of vitamin D3

Vitamin D3 plays a fundamental role in various bodily processes. According to the European Food Safety Authority (EFSA), the following health claims have been approved:

• Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus.
• Vitamin D contributes to the maintenance of normal blood calcium levels.
• Vitamin D contributes to the maintenance of normal bones.
• Vitamin D contributes to normal muscle function.
• Vitamin D contributes to the normal function of the immune system.

These benefits are especially relevant for people with low sun exposure, older adults, pregnant or breastfeeding women, and those following restrictive diets.

How much vitamin D3 do you need? Recommended dosage

The recommended daily dose of vitamin D varies according to age, health status, and sun exposure. In Spain, health authorities suggest an intake of 600 to 800 IU per day for adults, although many people may need higher doses, especially in winter. This supplement provides 5000 IU (125 mcg) per capsule, a high dose that should be used under professional supervision. The tolerable upper limit (UL) established by EFSA is 4000 IU per day for adults, so higher doses should be recommended by a doctor.

It is recommended to take 1 capsule daily, or as directed by a healthcare professional. It is important not to exceed the recommended dose without medical advice.

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 the human body produces when exposed to the sun. Various studies suggest that vitamin D3 is more effective at raising and maintaining blood vitamin D levels. This supplement uses vegan-sourced vitamin D3, obtained from lichens, which guarantees its effectiveness and suitability for vegan diets.

When choosing a supplement, the D3 form is generally preferred for its greater bioavailability and long-lasting effect.

How to choose the best vitamin D supplement

When selecting a vitamin D supplement, it is important to consider several factors:

• Form of vitamin D: Opt for D3 (cholecalciferol) for better absorption.
• Origin: If you are vegan, look for D3 from lichens instead of lanolin.
• Dosage: Adjust the dose to your needs and consult with a professional.
• Quality and purity: Look for products that are allergen-free, non-GMO, and have third-party certifications.
• Brand commitment: Brands like Natural Factors that control the entire production chain offer greater assurance.

This supplement meets all these criteria: it is vegan, non-GMO, free of common allergens, and manufactured under strict quality standards.

Possible side effects and contraindications

Vitamin D3 is generally safe when taken at recommended doses. However, very high doses (above 4000 IU per day long-term) can lead to toxicity, with symptoms such as nausea, weakness, and kidney problems. Its use is not recommended in people with hypercalcemia or certain kidney diseases without medical supervision. Always consult a healthcare professional before starting any supplementation, especially if you are pregnant, breastfeeding, or taking other medications.
