Boys from 9 to 18 years old have the maximum natural need for calcium. More than pregnant women. Around 1,300 milligrams of calcium a day.
Children usually get 75% of their calcium from dairy products. If a child is allergic to cow's milk, then fortified (fortified) calcium drinks such as fruit juice or milk replacer should be given to him to wash his food (if he drinks it). Or soy foods with calcium. Or cereals and flakes, specifically fortified with calcium.

That is, if there is not enough calcium, then it is necessary to literally force it into the bones. Exercise.
It is advisable not to drink sugary soda, because for some unknown reason it weakens the bones of children.
Well, it is better for him not to start smoking, because with a lack of calcium, smoking also badly affects the bones. That is, this pampering will be more harmful for him than for other guys. For the same reason, it is better not to smoke next to the boy.
How long? All life. But before the age of 18, it is especially important to monitor calcium.
