Vitamin D (vitamin D) is known as "sun vitamin". It is the only vitamin that can be naturally synthesized through enough sunlight, and can also be obtained from diet. In the past, vitamin D was thought to only increase the absorption of calcium phosphorus and prevent bone relaxation, but modern research has found that vitamin D is a type of steroid hormone.
Vitamin D works. There are many forms of vitamin D throughout the body, mainly vitamin D2 and D3. Vitamin D2 is present in plants and is produced by photosynthesis by keratinol; vitamin D3 is produced by irradiating the skin through yang light and reacting with ultraviolet light in the subcutaneous calcification sterol.Vitamin D has a lot of functions and can act on almost every organ of the human body. It can help absorb minerals and reduce bone relaxation risks, but it also enhances immunity, anti-inflammatory, and allergies, and reduces the chance of colds.
People with sleep disorders may have insufficient vitamin D intake. Vitamin D is also related to the prevention and prescription of many chronic diseases, such as diabetes, hypertension, cancer, etc.; research has found that increasing the concentration of vitamin D in the serum may reduce the chance of suffering from autoimmune diseases, such as type 1 diabetes, red spotted wolf abdomen, inflammation, asthma, etc.
How to replenish vitamin D? 1. Sunlight: After the human skin is exposed to sunlight, vitamin D can be synthesized. It is recommended to choose the strongest period of ultraviolet light from 11 to 13 noon, and sunlight for 10 to 15 minutes a day. 2. Natural food acquisition: Vitamin D2 mainly comes from plant foods, such as yeast, mushrooms, shiitake mushrooms, black fungus, algae, etc.Vitamin D3 is mainly derived from animal foods. Eat more foods such as fish, squid, fish, liver, egg yellow, cheese, etc., which helps supplement vitamin D.
3. Vitamin D supplement: People who are afraid of darkness and live in high-rise sunlight and are obscured, it is recommended that additional vitamin D supplements be taken. Generally, adults recommend that 400 to 2,000 IU of vitamin D be supplemented daily. Vitamin D3 is fat-soluble, and it can promote absorption with oil-based intake, and it is effective after eating. Vitamin D can effectively increase calcin absorption by 60%. If calcines are replenished at the same time, it can promote bone strength.Taking too much vitamin D can cause calcification to accumulate in the blood, causing calcification, vomiting, weakness, frequent urine, and even bone pain and calcification.
