For height, generally speaking, congenital genes account for 70%, and acquired living habits, exercise habits, eating habits and sleeping habits account for 30%. Experiments on twins in the United States found that maintaining good habits the day after tomorrow can increase by about 7cm on average. Nature cannot be changed.

Look what I wrote. I'm sure it will help you. Personality guarantee, your own summary and experience, lie to death! It is suggested to do a bone age test, that is, take an X-ray to see if your hand bones are closed and roughly infer whether you can get up.

In terms of diet and calcium supplementation. Actually, I don't think calcium tablets are necessary. As long as you pay attention to your diet and exercise reasonably, you generally need enough nutrition. A cup of fresh milk every morning and a cup of yogurt before going to bed at night are helpful to sleep (sleep is very important) and absorb nutrition. Eat more beans and ribs when you are free. Seafood, bones need enough calcium, and get more sunshine. People, like flowers, can't grow well without light watering, and so can people. More sun exposure helps to absorb calcium.

I said fresh milk. The pure milk we usually drink is sterilized by ultra-high temperature, and its shelf life is very long, about 30 days. But all the ingredients in it are lost, so it is not easy to be absorbed by people. When I say fresh milk, it is squeezed on the spot. It is called pasteurized milk abroad. You can search on Baidu, and the shelf life is relatively short, about 2 days. The reason why there are few China is that it requires high environmental protection, is easy to deteriorate and has high transportation cost.
