At this time, the vitamin D produced by the body can meet the requirements of strongly recommended daily intake. Through the glass, the ultraviolet rays in the sun can hardly penetrate the laminated glass, so it can't help the body to produce vitamin D and can't help the absorption of calcium. Sunlight is actually ultraviolet light. When ultraviolet rays are irradiated on the body, it can help others to produce vitamin D. Lack of vitamin D can cause rickets, which leads to indigestion and absorption of calcium. Many babies can't often go out for outdoor sports in winter because of the cold weather, and they can't help to produce vitamin D through the sunshine through the glass, so they should pay attention to vitamin D supplementation. For newborn babies, vitamin D can be supplemented after birth 14 days.
According to WHO's proposal, 400 enterprises can be filled every day, and this filling can be maintained until adolescence. For babies fed with formula milk powder, it can be reduced according to the content of vitamin D in infant milk powder. You can choose vitamin D drops, which is also convenient to eat. Sunshine bath can supplement calcium and zinc. But sunbathing can't supplement calcium and zinc immediately. On the contrary, according to the ultraviolet rays in the sun, it shines directly on the skin. There is a chemical substance called dehydrocarbs on the skin surface, which can produce vital vitamin D3, thus promoting the absorption of calcium. Ultraviolet rays cannot penetrate through laminated glass, so it is impossible to supplement calcium and zinc by sunbathing indoors through glass. However, most things that directly penetrate through laminated glass indoors are infrared sensing. Many women pursue beauty, go out after taking a shower every time, or are afraid of tanning.
Covering yourself with only two eyes, you can't produce vitamin d3 according to the ultraviolet rays in the sun. Because they block the skin after bathing, they can't make dehydrohydrocarbons and ultraviolet rays generate vitamin D3, and calcium and zinc supplementation certainly have no practical effect. Ultraviolet rays of certain wavelengths in the sun can enhance 7- dehydrocarbohydrates in the skin and form provitamin D3. Using the environmental temperature of the skin itself, pre-vitamin D3 is converted into vitamin D3. Vitamin D3 is transported, digested and absorbed into the blood according to the lymphatic circulation in the body, and then passes through the liver and spleen. Vigorous vitamin D can also help the body absorb calcium and phosphorus, which can make our human bones look stronger. In other words, the digestion and absorption of calcium in everyone is inseparable from the vitality of vitamin D.
