1,What is vitamin D3?
Vitamin D3 (cholecalciferol) is mainly synthesized by the human body itself. Human skin contains a type of cholesterol, which becomes vitamin D3 when exposed to sunlight. Therefore, if the child can fully receive direct sunlight on the skin for more than 4-6 hours, the vitamin D3 synthesized by itself can basically be satisfied. However, under the influence of the rise of skin cancer caused by ultraviolet radiation, air pollution, and weather changes in various places, the time that people in various countries receive sunlight is decreasing, and many countries clearly stipulate that the time of receiving sunlight should be limited. Therefore, worldwide There is widespread deficiency of vitamin D. In addition, vitamin D3 can also come from animal foods, such as liver, especially cod liver oil extracted from seafood. Except for a few animal foods, vitamin D3 is mainly formed by 7-dehydrocholesterol in the skin after being irradiated by ultraviolet rays, while 7-dehydrocholesterol is formed by the transformation of cholesterol, so some people call it the sun vitamin.
vitamin D3 liquid is fat-soluble, insoluble in water, only soluble in fat or fat solvent, and resistant to high temperature and oxidation in neutral and alkaline solutions. According to the experiment, when heated at 130 degrees for 90 minutes, its physiological prevalence is still not destroyed, but it is gradually decomposed and destroyed under acidic conditions. Generally, the food will not be lost in the process of cooking and adding styles. Destruction of D3. There are two units of measurement for vitamin D3, the weight unit and the international unit. 1 microgram of D3 is equivalent to 40 international units; or 1 international unit of vitamin D3 is equivalent to 0.025 micrograms of cholecalciferol.
Vitamin D3 is most abundant in sea liver. For example, every 100 grams of cod, flounder and swordfish liver contains vitamin D3200~750 micrograms, 500~10000 micrograms, and 25000 micrograms, respectively. Others such as herring, salmon, sardines and pomfret whales contain a small amount; poultry liver, eggs and milk also contain a small amount, less than 100 micrograms per 100 grams. In general, it is not easy to get enough vitamin D3 from food alone, so the synthesis of vitamin D3 in the body through sunbathing is a particularly important way.

What's function of vitamin D3 K2?
Vitamin D3 transports calcium from the intestines to the blood. In fact, vitamin D3 supplementation alone is not enough, because after calcium reaches the blood vessels, vitamin K2 must be deposited into the bones for absorption by the bones.
