The Chinese Nutrition Society recommends an age-related daily intake of vitamin D₃ of 600 IU/day for people aged 65 and above, and 400 IU/day for others.
Vitamin D₃ plays a huge role in the human body and is vital for the growth and development of young children, which can promote the absorption of calcium and phosphorus, the development of bones and teeth in young people, and the prevention of rickets, with a recommended intake of 400IU/day. For the elderly over 65 years old can prevent osteoporosis and soft tissue calcification, the recommended intake is 600IU/day.
In addition, appropriate increase in sun exposure time (time at least half an hour), or increase the intake of cheese, egg yolks, dried mushrooms and other foods, can also be supplemented with vitamin D₃.
In addition, the recommended intake of vitamin D₃ in Europe and the United States is higher than that in China. If supplementing vitamin D3 for medication it is recommended to do so under the guidance of a physician. Do not take it blindly.
