Mason Natural Vitamin D3 1000 IU (25 mcg) from Fish Liver Oil, 120 Softgels

What is vitamin D and why is it important?

Vitamin D is a fat-soluble nutrient essential for the body. Its main function is to regulate the absorption of calcium and phosphorus, key minerals for bone health. In addition, it participates in the normal functioning of the immune system and muscle contraction. Although we can obtain it through sun exposure and certain foods, many people do not reach adequate levels, especially in months with little sunlight or in populations at risk of deficiency.

Mason Natural Vitamin D3 1000 IU offers a bioavailable form of vitamin D3 (cholecalciferol) from fish liver oil. Each softgel provides 1000 IU (25 mcg), an adequate dose for maintaining optimal levels in adults.

Health benefits of vitamin D

According to the European Food Safety Authority (EFSA), vitamin D contributes to:

• Normal absorption and utilization of calcium and phosphorus.
• Maintenance of normal blood calcium levels.
• Maintenance of normal bones.
• Normal muscle function.
• Normal immune system function.

In addition, it plays a role in the cell division process. These benefits are backed by decades of research and are recognized by European health authorities. Incorporating a quality vitamin D3 supplement can help meet daily needs, especially in people with limited sun exposure, over 50 years of age, or those following restrictive diets.

How much vitamin D do you need? Recommended dose

The recommended daily dose for adults varies depending on age, lifestyle, and sun exposure. In the European Union, the reference intake for vitamin D is 5 μg (200 IU) per day, although many health organizations suggest higher amounts to maintain optimal levels. Mason Natural Vitamin D3 provides 1000 IU per capsule, a dose that is within the safe and effective range for most adults.

It is recommended to take one softgel daily, preferably with a meal containing fat to improve its absorption. If you have questions about the appropriate dose for you, consult a healthcare professional.

Differences between vitamin D2 and D3

There are two main forms of vitamin D: D2 (ergocalciferol), of plant origin, and D3 (cholecalciferol), which is what the body produces after sun exposure and what is found in foods of animal origin. Vitamin D3 is considered more effective at raising and maintaining blood vitamin D levels, as it has a higher affinity for transport proteins and a longer half-life.

Mason Natural uses vitamin D3 from fish liver oil, a natural and well-absorbed source. When choosing a supplement, the D3 form is usually preferred due to its higher bioavailability and effectiveness.

How to choose the best vitamin D supplement

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

• Form: Vitamin D3 (cholecalciferol) is the most recommended for its effectiveness.
• Source: It can be from lanolin (sheep), fish liver oil, or lichen (vegan). This product comes from fish liver oil, which also naturally provides omega-3 fatty acids.
• Dose: 1000 IU is a common dose for maintenance. Higher doses may be necessary under medical supervision.
• Purity: Look for products without unnecessary additives. Mason Natural contains no milk, eggs, gluten, peanuts, wheat, shellfish, tree nuts, or artificial preservatives.
• Quality and trust: Brands with decades of experience and manufacturing under Good Manufacturing Practices (cGMP) offer greater assurance. Mason Natural has met these standards for over 50 years.

This product is a food supplement and should not be used as a substitute for a balanced diet. Maintaining a varied diet and a healthy lifestyle is essential for overall well-being.
