According to the recommendations of the Institute of Medicine, the recommended amount of vitamin D3 is in the food to improve bone health as follows:

Vitamin D2 opposite D3

Vitamin D is an important vitamin for the health of the body and lies in two forms that have a similar chemical structure: Vitamin D2 (Ergocalcififerol) and vitamin D3 (cholecalciferol).

In fact, both types of vitamin D cover the needs of the body, but the difference between vitamin D2 and D3 is in some important points we explain below:

Sources:

Natural sources: The difference between vitamin D and D3 is that vitamin D3 can be obtained by the action of the ultraviolet rays of the sun.

Food sources: Vitamin D3 is included in food from animal sources, while vitamin D2 can be obtained from vegetable sources and enriched foods.

Here are some food sources for each of them:

Sources for vitamin D3: fat fish, fish oil, egg yolk, butter, liver and dietary supplements.

Sources for vitamin D2: mushrooms, enriched foods and dietary supplements.

Production:

The difference between vitamin D2 and vitamin D3 with respect to the production is that vitamin D3 can be synthesized by the action of sunlight, since dehydrocholesterine, which occurs in the layers of the skin, converted by the action of UV rays in vitamin D3 will. Similar to plants, vitamin D2 is formed from the ergosterol compound which occurs in vegetable oils.

effectiveness

Some one likes to ask what the difference between vitamin D2 and vitamin D3 is in relation to its effectiveness in the body and which of the two is stronger.

It seems that the difference between vitamin D2 and D3 is in terms of their effectiveness in the different ability to increase the vitamin D levels in the body.

Although both are included in the bloodstream, they are metabolized in the liver, whereby vitamin D2 is converted into 25-hydroxyvitamin D2 and vitamin D3 in 25-hydroxyvitamin D3, both of which are referred to as Calciferol.

However, vitamin D3 produces more Calciferol as vitamin D2, as the results of vitamin D analysis in persons show vitamin D2 and vitamin D3 preparations.

Additions:

Here are some important differences between a vitamin D2 supplementation and a vitamin D3 supplementation:

Composition:

A vitamin D3 supplement preparation corresponds to the natural vitamin D3, which forms the skin by the action of sunlight, while vitamin D2 is not produced naturally in the human body.

Toxicity:

The toxicity of vitamin D is different depending on the type. The toxicity of vitamin D3 is probably less than that of vitamin D2, which is due to the different ratios in binding to the vitamin D receptors in the body.

Stability:

Vitamin D3 is more stable than vitamin D2 so that a vitamin D3 supplement is likely to remain more effective under different conditions such as temperature fluctuations and changed storage conditions.
