Vitamin D belongs to the group of fat-soluble vitamins. Sufficient vitamin D intake provides several important functions. Probably the most important of these is the regulation of calcium and phosphorus absorption, which affects the condition and development of bones and teeth. Among other things, vitamin D also helps the immune system to function properly.

Human body naturally produces vitamin D when exposed to direct sunlight. However, vitamin D can also be obtained from certain foods, such as fish or eggs or from supplements. These sources are particularly important in the autumn and winter months when it is almost impossible to get regular exposure to direct sunlight.

• Vitamin D contributes to the proper absorption and utilisation of calcium and phosphorus
• Vitamin D contributes to good bone and teeth health
• Vitamin D supports proper immune system function
• Vitamin D supports proper muscle function
• Vitamin D participates in the process of cell division

Relationship between vitamin D and fats

Vitamin D is a fat-soluble vitamin, which means that fat intake is important for optimal absorption. This is why each Natios Vitamin D3 softgel capsule contains extra virgin olive oil which is an excellent source of fat. However, it is important to note that not every type of fat affects vitamin D3 absorption in the same way. Many products contain linseed oil instead of olive oil which, however, is not optimal for supplementation when combined with vitamin D3.

• Both extra virgin olive oil and flaxseed oil are full of healthy unsaturated fats but they differ in type.
• Flaxseed oil contains mostly polyunsaturated fats, while extra virgin olive oil primarily consists of mono-unsaturated fats. Research indicates that vitamin D absorption is positively influenced mainly by mono-unsaturated fats.
• Another important difference is the stability of the two oils. Flaxseed oil is very susceptible to oxidation, making it very unstable. In fact, linseed oil is so unstable that it cannot be heated, must be stored in the refrigerator and consumed within a few weeks. This is not the case with extra virgin olive oil.

Forms of vitamin D

Vitamin D is available in two forms, Ergocalciferol (D2) and Cholecalciferol (D3). These two forms differ slightly from each other. Both forms increase blood levels of vitamin D and both provide vitamin D benefits. However, research indicates that vitamin D3 is more effective for increasing blood levels of vitamin D than vitamin D2.
