Vitamin D3, also known as Cholecalciferol, is a kind of vitamin D. Vitamin D is a fat soluble vitamin and is also regarded as a hormone precursor that acts on calcium and phosphorus metabolism. It is closely related to sunlight, so it is also called "sunshine vitamin".
Vitamin D2 is produced by Ergosterol in plants irradiated by ultraviolet light, which is rarely found in nature. Vitamin D3 is the most biologically metabolized active form of vitamin D.
Vitamin D3 (Cholecalciferol) is mainly synthesized by the human body itself. The human skin contains a kind of cholesterol, which becomes vitamin D3 after being exposed to the sun. So, if a child can fully receive direct sunlight on the skin for more than 4-6 hours, their own synthesis of vitamin D3 can basically be met. However, due to the rise in skin cancer, air pollution, and changes in weather caused by ultraviolet radiation, the time people in various countries receive sunlight is decreasing, and many countries have clearly stipulated restrictions on the time they receive sunlight. Therefore, vitamin D is widely lacking worldwide. In addition, vitamin D3 can also come from animal food, such as liver, especially Cod liver oil extracted from fish liver of marine products.
Sea fish is the most abundant source of vitamin D3, such as 3200-750 micrograms, 500-10000 micrograms, and 25000 micrograms of vitamin D per 100 grams of cod, flatfish, and swordfish liver, respectively. Others, such as herring, salmon, sardine and pomfret whales, contain a small amount; Livestock liver, eggs, and milk also contain small amounts, with a content of less than 100 micrograms per 100 grams. In general, obtaining sufficient vitamin D3 from food alone is not easy, so synthesizing vitamin D3 in vivo through sunbathing is a particularly important pathway.
The main sources of vitamin D3 include fish, fish eggs, animal liver, egg yolk, cream, butter, dry cheese, meat, milk, fruits, nuts, vegetables, and grains.

VD3 is a vitamin that plays an important role in human metabolism and physiological functions, especially in calcium and phosphorus metabolism. If patients take calcium supplements, they need the help of vitamin D3 to be well absorbed and utilized. At the same time, it can also promote calcium deposition in new bone formation sites, promote bone calcification, osteoblast function and bone like tissue maturation, so it can be used to prevent and treat Vitamin D deficiency.
Vitamin D3 is closely related to cardiovascular diseases and decreased immune function. Lack of vitamin D3 will increase the risk of cardio cerebral Vascular disease and tumors, reduce the resistance and be prone to infection. Therefore, vitamin D3 can reduce the risk of cardiovascular disease.
Some people may experience gastrointestinal irritation such as nausea and vomiting after taking vitamin D3. Because vitamin D3 promotes the absorption of calcium in the intestinal tract, sometimes it may greatly increase blood calcium, causing hypercalcemia.
The function:
1. Improve the absorption of calcium and phosphorus by the body, and achieve saturation of plasma calcium and phosphorus levels.
2. Promote growth and bone calcification, promote tooth health;
3. Increase the absorption of phosphorus through the intestinal wall and the reabsorption of phosphorus through the renal tubules;
4. Maintain normal levels of citrate in the blood;
5. Prevent amino acid loss through the kidneys.
