Mason Natural Vitamin D3 1000 IU (25 mcg) from Fish Liver Oil, 180 Capsules (3 Bottles of 60)

What is vitamin D and why is it important?

Vitamin D is a fat-soluble nutrient essential for the body. It is mainly obtained through sun exposure and, to a lesser extent, from certain foods. However, in Spain, during the winter months or in people with little sun exposure, vitamin D levels can drop considerably. This vitamin plays a key role in the absorption of calcium and phosphorus, fundamental minerals for maintaining strong bones and teeth. In addition, it contributes to the normal functioning of the immune system and muscles.

The product we present contains vitamin D3 (cholecalciferol), the most bioavailable form and the one the body produces naturally. Each softgel capsule provides 1000 IU (25 mcg) of this vitamin, extracted from highly refined fish liver oil. This pack includes three containers of 60 capsules each, providing a supply for 180 days.

Health benefits of vitamin D

Vitamin D has several properties backed by the European Food Safety Authority (EFSA). Among its most notable benefits are:

• Calcium and phosphorus absorption: Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, essential for bone mineralization.
• Bone maintenance: Helps maintain bones in normal conditions, reducing the risk of bone fragility.
• Muscle function: Promotes normal muscle function, which is important for mobility and balance.
• Immune system: Contributes to the normal functioning of the immune system, helping the body's defenses.
• Cell division: Vitamin D also participates in the cell division process.

It is important to remember that these benefits are part of a balanced diet and a healthy lifestyle. Vitamin D does not replace a varied diet or adequate sun exposure.

How much vitamin D do you need? Recommended dose

The amount of vitamin D each person needs can vary depending on age, sun exposure, skin pigmentation, and certain health conditions. As a general reference, many health authorities recommend a daily intake of 600 to 800 IU for adults, although in cases of deficiency, higher doses may be necessary under medical supervision.

Each capsule of this supplement provides 1000 IU of vitamin D3, a dose that is within the range considered safe for most adults. It is recommended to take one capsule daily, preferably with a meal containing fat to improve its absorption. This pack of three containers of 60 capsules offers a supply for 180 days, facilitating continuous consumption.

If you have questions about the appropriate dose for you, consult a healthcare professional. It is not recommended to exceed the daily dose without medical advice, as excessive consumption of vitamin D can have adverse effects.

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, such as mushrooms exposed to UV light, while D3 is the form that human skin produces when exposed to the sun and is also found in animal foods, such as fatty fish.

Numerous studies indicate that vitamin D3 is more effective than D2 in raising and maintaining blood levels of vitamin D. This is because the body uses it more efficiently. For this reason, most supplements opt for the D3 form. This product uses vitamin D3 from fish liver oil, a natural and high-quality source.

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) due to its higher bioavailability.
• Source: It can be of animal origin (lanolin, fish oil) or plant origin (lichen). Choose according to your dietary preferences.
• Dosage: 1000 IU is a common dose for general maintenance. Higher doses may be necessary under medical recommendation.
• Purity and quality: Look for brands that apply good manufacturing practices (cGMP) and carry out quality controls.
• Additional ingredients: Check that it does not contain unwanted allergens. This product is gluten-free, milk-free, egg-free, shellfish-free, and nut-free, although it contains soy and fish.

Possible side effects and contraindications

Vitamin D is generally safe when consumed in recommended doses. However, excessive and prolonged intake can lead to toxicity, with symptoms such as nausea, weakness, or kidney problems. People with certain conditions, such as hypercalcemia, sarcoidosis, or kidney disease, should consult their doctor before taking vitamin D supplements. This product is contraindicated in case of allergy to fish or soy.
