Uses and synthesis of Vitamin D3 Powder

Vitamin D3 Powder, also known as cholecalciferol, is a type of vitamin D that has been shown to be the true active form of vitamin D in the body. There are at least 10 known forms of vitamin D, but the most important are vitamin D2 (ergocalciferol) and Vitamin D3 CAS 67-97-0 (cholecalciferol).

Vitamin D3 Powder primarily regulates calcium and phosphorus metabolism in the body. Vitamin D3 is converted from 7-dehydrocholesterol in the skin by ultraviolet light exposure.

Vitamin D3 CAS 67-97-0 is a fat-soluble vitamin known as the "sunshine vitamin" because most people can synthesize their own vitamin D from UV light and cholesterol in the skin with moderate exposure to sunlight.

Vitamin D3 CAS 67-97-0 (mainly synthesized by the human body itself, the human skin contains a kind of cholesterol, after exposure to sunlight, it becomes Vitamin D3 Raw Materials. The Vitamin D3 Raw Materials synthesized by the child can basically satisfy his/her needs.

Applications / Functions of Vitamin D3 Powder

• 1）Improve the body's absorption of calcium and phosphorus, so that plasma calcium and plasma phosphorus levels reach the saturation level;
• 2）Promote growth and calcification of bones and sound teeth;
• 3) increasing phosphorus absorption through the intestinal wall and increasing phosphorus reabsorption through the renal tubules;
• 4) maintaining normal levels of citrate in the blood;
• 5) preventing the loss of amino acids through the kidneys.

Vitamin D3 CAS 67-97-0 (can keep the metabolism of calcium and phosphorus normal, can promote the body's absorption of calcium and phosphorus, when lacking, children are prone to rickets. China's regulations can be used to fortify margarine, the use of 125-156μg/kg; in the fortification of dairy products, the use of 63-125μg/kg; in the fortification of baby food, the use of 50-100μg/kg; in the fortification of milk and milk beverages, the use of 10-40μg/kg; in the fortification of solid beverages and ice cream, the maximum use of 10-20μg/kg. Maximum use level is 10～20μg/kg in fortified solid beverages and ice cream.

Vitamin D3 Powder can keep the metabolism of calcium and phosphorus normal and promote the absorption of calcium and phosphorus. The utilization rate of vitamin D2 and D3 in pigs is equal, but the utilization rate of vitamin D2 in poultry is only 1/40-1/30 of that of D3.When vitamin D3 is deficient, eggshells become thin, egg production rate decreases and rickets occurs. Dosage 1000-1500IU/kg.

Vitamin D3 Powder is a fat-soluble vitamin. There are more than a dozen known compounds with vitamin D effect, no series of sterol derivatives, of which the two of practical significance are vitamin D2 and vitamin D3. D3 is predominant in the world, and the "international standard substance" of vitamin D is also a pure crystallization of D3. The main function of vitamin D is the metabolism of calcium and phosphorus, and it is difficult to promote the absorption of calcium and phosphorus as well as the calcification of bones. When the human body lacks D, the ability to absorb calcium and phosphorus decreases, and the level of calcium and phosphorus in the blood decreases, so that calcium and phosphorus can not be deposited in the bone tissue, and even bone salts will dissolve, hindering the calcification of bones. When children are deficient, they get rickets, and adults get osteochondrosis. In Japan, D2 is produced and used mostly, with 30% of the demand for pharmaceuticals, 65% for feed additives, and 5% for food additives. According to the "Hygienic Standard for the Use of Food Nutritional Enrichment Agents (1993)" issued by the Ministry of Health of China, D2 and D3 as nutritional supplements can be used in liquid milk, margarine, dairy products, and baby food.

Vitamin D3 CAS 67-97-0 is mainly used in food, health products and other related products.

Vitamin D3 Raw Materials acts through a receptor that is a member of a family of ligand-dependent transcription factors that regulate the proliferation and differentiation of normal and cancerous cells and has anti-proliferative and anti-metastatic effects on breast, colon and prostate cancer. Activated Vitamin D receptors in the intestine and bone also maintain calcium absorption and homeostasis.

Vitamin D3 Raw Materials Vitamin D3 Powder mainly promotes intestinal calcium and phosphorus absorption and deposition, used in the treatment of rickets and osteomalacia.

Vitamin D3 Powder properties and stability

Production method of Vitamin D3 Powder

Dissolve 7-dehydrocholesterol in ethanol, open the ring with UV irradiation, the reaction solution is concentrated, frozen, filtered, the filtrate is concentrated to dryness under reduced pressure with nitrogen, and crude vitamin D3 liquid is obtained. The Vitamin D3 Raw Materials are then refined.

Vitamin D3 Powder is naturally found in liver, milk and egg yolks. The industrial production method is to extract the 7-dehydrocholesterol, which cannot be absorbed by the human body, from vegetable oils or yeast, and then dissolve it in chloroform or cyclohexane, and then transform it into Vitamin D3 by UV irradiation in a quartz glass flask.

Vitamin D3 CAS 67-97-0 occurs naturally in liver, milk and egg yolks, and is produced industrially by extracting 7-dehydrocholesterol, which cannot be absorbed by the human body, from vegetable oils or yeast, then dissolving it in chloroform or cyclohexane and converting it into Vitamin D3 CAS 67-97-0 by UV irradiation in a quartz glass flask.
