Vitamin D3

fat-soluble vitamin

Vitamin D3 is a fat-soluble vitamin, known as the "sunshine vitamin" because most people can synthesize their own vitamin D using ultraviolet rays and cholesterol in the skin when the skin is moderately exposed to sunlight. It is mainly synthesized by the human body. The human skin contains a type of cholesterol, which turns into vitamin D3 after exposure to sunlight. Therefore, if children can fully receive direct sunlight on their skin for more than 4 to 6 hours, the vitamin D3 synthesized by themselves can basically meet their needs.

Description

Vitamin D3 is also known as cholecalciferol. It is converted from 7-dehydrocholesterol in the skin by ultraviolet irradiation and is one of the most important forms of vitamin D. Vitamin D is a fat-soluble vitamin, which acts as a hormone precursor of calcium and phosphorus metabolism. It is closely related to sunlight, so it is also called "sunshine vitamin".

Physiological functions and effects：

1) Improve the body's absorption of calcium and phosphorus, so that the levels of plasma calcium and plasma phosphorus reach saturation;

2) Promote growth and bone calcification, and promote healthy teeth;

3) Increase phosphorus absorption through the intestinal wall and increase phosphorus reabsorption through the renal tubules;

4) Maintain normal levels of citrate in the blood;

5) Prevent amino acids from being lost through the kidneys.

Vitamin D is a fat-soluble vitamin. There are more than a dozen compounds known to have vitamin D effects, and there are no steroid derivatives. Among them, vitamin D2 and vitamin D3 are of great practical significance. D3 is the main vitamin in the world, and the "international standard substance" of vitamin D is also pure crystal of D3. The main function of vitamin D is the metabolism of calcium and phosphorus, and it is difficult to promote calcium and phosphorus absorption and bone calcification. When the human body lacks D, the ability to absorb calcium and phosphorus is reduced, and the calcium and phosphorus levels in the blood decrease, so that calcium and phosphorus cannot be deposited in bone tissue, and even bone salts will dissolve, which hinders the calcification of bones. Children who lack D will suffer from rickets, and adults will suffer from osteomalacia. Japan produces and uses most D2. Among the various demands, medicine accounts for 30%, feed additives account for 65%, and food additives account for 5%. According to the "Sanitary Standards for the Use of Food Nutrition Fortifiers (1993)" promulgated by the Ministry of Health of my country, D2 and D3 as nutritional supplements can be used in liquid milk, margarine, dairy products and infant food.

Product Features

NO01

Natural Source

As a source of vitamin D3, lichens are naturally pure. Lichens grow in natural environments without artificial synthesis or chemical treatment, retaining the most original nutrients.

NO02

Efficient absorption

Vitamin D3 from lichens has the advantage of efficient absorption. Studies have shown that vitamin D3 in lichens has similar structure and biological activity to vitamin D3 synthesized by the human body, and is more easily absorbed and utilized by the human body.

NO03

Promote calcium absorption

Vitamin D3 plays a key role in maintaining bone health. It can promote the intestinal absorption of minerals such as calcium and phosphorus, increase the concentration of calcium and phosphorus in the blood, and provide sufficient raw materials for bone growth and maintenance.
