Health for All says
As we all know, calcium is the cornerstone of our physical health and plays a pivotal role in the growth and development of children. Calcium deficiency is like a trickle that affects children's bone development, which not only hinders their growth, but also has a certain impact on their intellectual development.
Those things about "calcium supplementation" in the market
1. "Heightening" calcium tablets may just be advertising and marketing!
The role of calcium tablets is not to "increase height", but only to "supplement the insufficient calcium nutrition in the diet"!
Calcium supplementation is a necessary but not sufficient condition to promote height growth, and a variety of methods are required to promote height growth.
Therefore, it is not reliable to "increase" calcium tablets!
2. Early bone age is not the fault of calcium supplementation!
Bone age growth is a process of gradual ossification and fusion of epiphyseal growth plate cartilage, which is mainly regulated by endocrine hormones.
Calcium supplementation provides a material basis for bone growth, has no effect on the differentiation and proliferation of epiphyseal cartilage, and will not accelerate bone age growth.
3. It is more appropriate to supplement calcium after dinner!
Calcium supplementation requires gastric acid to participate in digestion, so it is advisable to take it within 1 hour after a meal, and it is recommended that it is better after dinner among the three meals, because the dinner is relatively light, less meat, eggs and milk, and the calcium content in the diet is relatively less, which is more conducive to the absorption of additional calcium in the intestine.
In addition, calcium is lost when the body produces urine, and calcium can be supplemented from breakfast and lunch during the day, but at night, when the urine production does not stop, additional calcium supplements are needed after dinner.
4. What nutrients do I need to supplement while supplementing calcium?Vitamins D and K
There are two key points of calcium supplementation: absorption into the blood and deposition into the bone.
Everyone knows that supplementing vitamin D with calcium can help improve the absorption rate of calcium nutrients in the intestine and increase blood calcium concentration.
Another key nutrient that facilitates the transport of calcium into bone cells – vitamin K – as blood flows through the bones.
Therefore, it is recommended to supplement vitamins D and K at the same time as calcium supplementation.
Note: While taking calcium, do not use ** products, soy products or other high-calcium foods at the same time, so as to avoid consuming more at the same time to reduce the intestinal absorption rate and cause waste.
5. "Organic calcium" and "inorganic calcium" are the most important!
Calcium carbonate, calcium phosphate, calcium lactate, calcium acetate, calcium citrate, calcium gluconate, calcium seaweed, etc., how to choose?
It is roughly divided into two categories: inorganic calcium and organic calcium
Inorganic calcium: calcium carbonate, calcium phosphate, etc., high calcium content, gastric acid dissolution is required to be well absorbed, suitable for children with good gastrointestinal digestion function and large calcium demand
Organic calcium: calcium lactate, calcium acetate, calcium citrate, calcium gluconate, calcium citrate, seaweed calcium, etc., with low calcium content, but good solubility, suitable for children with weak digestive function (or eating inorganic calcium has an uncomfortable reaction), but be sure to pay attention to calculate whether the amount of elemental calcium supplement is up to standard!These calcium supplements are wrong, starting calcium supplementation after birth
For children aged 0 to 6 months, breast milk can provide sufficient calcium, and no additional supplementation is required, and it is also a VD supplement to promote better calcium absorption.
Let your child eat more meat and less vegetables
The meat of chickens, ducks, cattle and sheep and other poultry and livestock commonly found on the table contains very little calcium, and the calcium content in 100g of meat is less than 15mg.
On the contrary, some green vegetables have a calcium content of as high as 50 130mg per 100g.
Only calcium supplementation, not vitamin D supplementation
Many parents often think that as long as enough calcium is enough, they ignore the question of whether calcium can be effectively absorbed by the body. It's like a person has countless treasures, but if there is no effective way to exploit them, then the treasures lose their value. Therefore, while supplementing calcium, we must pay attention to vitamin D3 supplementation. Vitamin D3 acts as a wise mentor to guide calcium to be better absorbed and utilized by the body. In the complex site of the small intestine, the active form of vitamin D3 can induce a special protein. This protein acts as a guide for calcium, binding tightly to calcium ions, acting as a carrier to transport calcium into the bloodstream. At the same time, this protein also increases the permeability of calcium to the mucosa of the small intestine, allowing calcium to be more easily transported through the mucosa into the bloodstream. It's like a wide door that allows calcium to pass through and get into the body to be fully utilized. 
Therefore, while parents are concerned about their children's calcium supplementation, they should not forget to supplement vitamin D3. Only when calcium and vitamin D3 work synergistically can we ensure that calcium is effectively absorbed and utilized by the body, laying a solid foundation for the healthy growth of children.
