Do I need to take vitamin D to supplement calcium?

In today's society, the dietary structure of many people is unreasonable. Everyone knows the importance of calcium supplementation. However, people also have various misunderstandings on the matter of calcium supplementation. For example, many people think that eating green vegetables cannot supplement calcium. In fact, spinach, cabbage, rapeseed and other vegetables are rich in calcium, so eating more vegetables can also play a role in calcium supplementation. Do you need to take vitamin D during the calcium supplementation process?

Do I need to take vitamin D to supplement calcium?

Assuming there is enough milk, the calcium content is still sufficient. However, when supplementing calcium, you should also pay attention to supplementing vitamin D, because vitamin D promotes calcium absorption. When vitamin D is deficient, the calcium absorption rate is 10% to 15%. If vitamin D is supplemented, the absorption rate can reach more than 40%. Therefore, you must supplement vitamin D while supplementing calcium. If you supplement with casein calcium, you do not need to supplement with vitamin D. This is the latest generation of biological calcium and can be directly absorbed and utilized by the human body without the need for vitamin D.

Of course, in the summer, the sun is better and you can go outdoors to get more sun. When there is enough sun exposure, the body can synthesize vitamin D on its own, and calcium absorption is better at this time. This is a very important aspect of calcium supplementation.

Will calcium supplementation cause constipation?

Some children will suffer from constipation when taking calcium supplements, because calcium has an astringent effect. When taking calcium supplements, their stools may become denser. If they take biological calcium, there will be no such problem.

Unless the child gets good sun exposure, he or she will need supplements. Because the real source of vitamin D is not from food, sun exposure can provide more than 95% of the vitamin D needed by the human body. It is recommended to sunbathe for more than 1-2 hours a day, and the area to be sunbathed should be relatively large, preferably the whole body. In winter, there is very little ultraviolet light in sunlight in areas above 35 degrees north latitude, so it is necessary to supplement vitamin D in winter. Simply sunbathing is not enough.

Therefore, general calcium supplements require additional vitamin D to be well absorbed by the human body. The latest generation of biological casein calcium (such as iCarbon casein calcium) uses a new generation of calcium supplement raw materials and can be well absorbed without the participation of vitamin D. It is currently the most ideal calcium supplement product.
