The long-term use of high doses of vitamin D3 in silver hair may increase the risk of dementia. Liu Yili, a nutritionist at Taiwan An Hospital, said that the focus of the research of the National Hospital is active vitamin (calcitriol), the drug "calcitriol" in the drug variety. It is not too worried about different health foods.
How to take vitamin D3? Zhu Zhili, deputy director of the Institute of Molecular and Genetic Medicine at the National Hospital, said that children's brains are still developing, and they are more practical to support children to take up sufficient amounts of vitamin D and calcification to prevent rium and maintain normal growth and development. People over the age of 65 should take active vitamin D3 carefully and pay attention to the dosage. It is best to discuss with the doctor first, and help the human body synthesize vitamin D through diet, exercise, and daily routines. As for young people with a family history of dementia, whether long-term vitamin replenishment is harmful remains to be studied further.
{9 1} Due to the impact of the epidemic, in the past two or three years, vitamin D, which is known as improving immunity and reducing internal inflammation, has become the most popular health food. Liu Yili pointed out that one microgram of vitamin D is equal to forty IU. According to the eighth edition of dietary nutrition suggestions, the daily vitamin D in adults is ten micrograms (400 IU), and over fifty years old, it can be increased to fifteen micrograms (600 IU), and the upper limit is fifty micrograms (2,000 IU).Liu Yili said that many people asked, "Is it good to eat all?", which seems to be different, but fish oil, calcines, and comprehensive vitamins all contain vitamin D. If you take a single pure vitamin D therapist and capsule, it may be too much if you accumulate.
Liu Yili said that vitamin D is reincarnated by the liver and kidneys. If excessive amounts are taken for a long time, it is still unknown whether it will increase the risk of dementia, but it is likely to cause abnormal liver and kidney function. It is recommended to take relevant health foods with caution.
In addition to health foods, Liu Yili said that sunlight is the best promoter for human synthesis of vitamin D. It is recommended that the public spend more time on sunlight and choose to wait for at least fifteen minutes a day.
In addition, vitamin D can also be collected through diet, including animal vitamin D3 such as fish (fish, fish, squid), milk, chicken eggs, etc. As for mushrooms, black fungus, and shiitake mushrooms that have been exposed to sunlight, they all contain rich vitamin D.
