Calcium is a very important element in human life, accounting for 1.5% to 2% of body weight, of which 99% exist in bones, teeth, toenails and fingernails, only 1% exists in the blood, in the cellular organization and extracellular fluids. Calcium strengthens the immune system and participates in the elasticity of muscle cells and in coagulation. Moreover, this mineral is also a major component in the formation of bones and teeth in young children. Suffering from calcium deficiency, children will be slow growing and stunted. They will have poor quality, uneven and easily decayed teeth.
The process of premature bone aging will cause many bone defects in children
However, the excessive supply of calcium to the body also causes adverse impacts on health. When the body receives too much calcium, high levels of calcium in the blood can enter the bones, which can lead to premature bone stiffness and restriction in bone development. The ossified bones will make children stop growing taller and become shorter than their peers. The premature bone aging is the cause of the risk of a series of bone defects in children such as curvature of the spine, humpback, flat chest, bow legs, etc.
The increased intake of calcium causes the kidneys to work continuously to increase the excretion of calcium through the urine. If this condition persists, it can easily lead to diseases such as ureteral stones and kidney stones. Having too much calcium hinders the process of absorption of other micronutrients, especially iron, zinc, magnesium, phosphorus... and causes malnutrition or illness in children. Calcium excess also causes gastrointestinal disturbances, loss of appetite, abdominal pain, frequent constipation.
Fatigue, dizziness, nausea, thirst, and frequent urination... are the most obvious signs of calcium excess. Nevertheless, in order to obtain precise results, the necessary tests should be performed if calcium level in the child's blood is high. At that time, the doctors will take appropriate measures.
Parents should pay attention to the age of their children to have proper calcium supplementation
The body's calcium requirements vary with age and primarily depend on bone development in each individual. According to the recommendation of WHO, the calcium requirements of children will vary with the following stages:
Children under 6 months old need 300 mg calcium/day; children from 7 to 12 months old: 400 mg/day; children from 1 to 3 years old: 500 mg/day; children from 4 to 6 years old: 600 mg/day; children from 7 to 9 years old: 700 mg/day; 10 years old children: 1000 mg/day; people from 11 to 24 years old: 1200 mg/day.
The safest way for calcium supplementation in children is to strengthen the intake of foods which contain high mineral levels such as shrimp, crab, fish, tiny shrimp, broccoli, etc. Excessive calcium from food intake will be excreted. According to some experts, parents should not let their children use calcium supplements. Instead, they should let their children use dietary supplements which contain Nanometer Calcium.
Nanometer Calcium, a completely new form of calcium, is prepared according to advanced nanotechnology. Thanks to its super micro size (<60 m), it possesses a good solubility. Therefore, it is absorbed rapidly through the intestinal membrane and a maximum amount of Calcium from the intestine will enter the blood. There will be no calcium excess which leads to constipation and kidney stones. As the result, Nanometer Calcium is safe for long-term use. Nanometer Calcium will help strengthen the skeletal system, increase height quickly and prevent rickets and osteoporosis.
