How does calcium help to grow taller?

There are various approaches to enhance children’s height, and nutrition plays a crucial role in this aspect. Among the essential minerals, calcium takes precedence as it provides the necessary nutrients for optimal growth and development in children. So, how does calcium specifically contribute to height growth? Let’s explore the information below, obtained from

Why do we need calcium supplements?

Calcium is an essential mineral that plays a critical role in the body. It is a vital component of bones, teeth, the cardiovascular system, and nerves. In a typical human body, 99% of calcium is found in bones and teeth, while the remaining 1% is distributed throughout blood vessels, muscles, tissues, and other organs.

The 1% of calcium outside of the bones is crucial for proper muscle contraction, blood clotting, and effective transmission of messages in the nervous system. It is essential for maintaining nerve and muscle activity, as well as ensuring normal cellular function throughout the body.

Throughout daily activities, the body loses calcium through sweat and excretion, resulting in gradual calcium depletion. In the absence of adequate calcium intake, the body “borrows” calcium from the bones and releases it into the bloodstream to maintain a stable calcium level.

Insufficient calcium in the bones can significantly impact bone development and lead to various problematic conditions. In adults, this can result in osteoporosis, an increased risk of fractures, poor memory, neurasthenia, headaches, and other issues. Children may experience weak and small bones, as well as deformities, which can hinder their growth.

It is evident that calcium plays a crucial role in the overall functioning and well-being of both children and adults. Therefore, it is essential to ensure an adequate daily intake of calcium to supplement and maintain the necessary levels in the body.

Functions and roles of calcium

Calcium is a crucial element in bone structure as it acts as a storage site for this mineral. The formation of bones begins early in fetal development, where a strong and flexible matrix is created, forming the foundation of the body’s skeletal structure. This matrix, which makes up about one-third of the bone, consists of collagen fibers coated with gelatin.

During the growth process, calcification occurs rapidly to enable the bones to support the body’s weight as the individual learns to walk. The ends of long bones contain spongy sections called trabeculae, which readily provide calcium to maintain normal levels of calcium in the blood. Throughout life, bones undergo continuous changes in shape and density influenced by factors such as age and weight gain.

Bone is a unique type of connective tissue with a distinct shape. It forms through two main processes: matrix formation, where the bone matrix is created, and mineral placement, where minerals like calcium are deposited into this matrix. Three types of cells, namely osteoblasts involved in bone formation, osteoclasts responsible for bone maintenance, and osteocytes contributing to bone resorption, play different roles in bone function.

Exposure to sunlight stimulates the body to produce vitamin D, which aids in the absorption of calcium into the bloodstream, facilitating its incorporation into bones.

How to supplement calcium to increase height

As the body cannot produce calcium on its own, it needs to be supplied from external sources. To prevent calcium deficiency, we can supplement it in the following ways:

Supplement Calcium through food:

The simplest and safest way to supplement calcium is through a diet that includes foods rich in this mineral. There are several calcium-rich foods that can be incorporated into one’s diet. Examples of such foods include prawns (1,120mg/100g), crabs (5,040mg/100g), fresh straw (3,520mg/100g), rock snails (1,660mg/100g), egg yolks (134mg/100g), and various vegetables like kale, bean sprouts, bok choy, celery, sweet potato, pumpkin, and nuts, which often contain more than 100mg of calcium per 100g serving.

Medical professionals recommend daily calcium intake based on age. For infants under six months, 300mg of calcium per day is recommended. Infants aged seven to 12 months require 400mg/day. Children between the ages of one and three need 500mg/day, while those between four and six years old need 600mg/day. Children aged seven to nine require 700mg/day. For children aged 10 and above, a daily intake of 1,000mg is recommended, and those between 11 and 24 years old need 1,200mg/day. Adults between 24 and 50 years old should aim for 800-1,000mg of calcium per day.

Ensuring that children meet the recommended daily calcium intake is essential for their proper growth and development, including achieving their maximum potential height.

Supplement calcium through milk:

Milk is a significant source of calcium, which plays a crucial role in promoting strong bones and teeth and reducing the risk of osteoporosis in later life. It is also an excellent source of vitamin D, which aids in the absorption of calcium into the bones. Milk is not only rich in calcium and vitamin D but also provides an adequate amount of protein and calories, supporting enhanced strength and muscle development. This is especially important for growing children who require these nutrients for proper growth and development. Therefore, establishing a daily habit of consuming milk can contribute to better height growth and overall health.

Supplement Calcium through supplement products:

In reality, the calcium obtained from the diet typically provides an average of around 400mg, which falls significantly short of the recommended daily intake of 800-1000mg. Moreover, not everyone enjoys the taste of milk or has a lactose-intolerant body or allergies to cow’s milk protein, making it challenging to obtain sufficient calcium solely from milk.

To address this deficiency, utilizing a Nano Calcium supplement is recommended. Nano Calcium is a form of calcium that is prepared using Nano technology, resulting in a super small size that enables quick absorption into the body without causing issues like kidney stones or constipation.

Furthermore, it is crucial to supplement other essential nutrients like hydrolyzed collagen type II, deer velvet, Hai Sam, and Do Trong to stimulate the pituitary gland’s production of growth hormone, which promotes better height growth.

Additionally, it is important to select height-increasing support products that are licensed by the US FDA for unrestricted circulation in the US and certified for nationwide distribution by the State Agency in Vietnam. This ensures both the safety and effectiveness of the products during use

When to start needing calcium supplements?

If a child fails to meet the daily calcium requirement and is at risk of calcium deficiency, it is essential to increase calcium intake. Specifically, calcium supplementation is necessary in the following cases:

When the diet is not guaranteed

In a child’s daily diet, it is common for them to have a dislike for calcium-rich foods such as shrimp, fish, and seafood. Additionally, some children may have a poor appetite and fail to consume enough calcium through their regular meals. In such situations, it becomes crucial for parents to ensure that children receive calcium supplementation.

When children are at risk of calcium deficiency

Children are prone to calcium deficiency due to various reasons. During infancy, calcium deficiency can occur if mothers restrict their calcium intake excessively or if the milk the child consumes lacks an adequate amount of calcium. Additionally, in the early years of life, children may face challenges with micronutrient deficiencies resulting from poor digestion.

Considering these factors, it is essential to provide calcium supplements to children when they exhibit the following signs:

  1. Difficulty sleeping or being easily startled.
  2. Restlessness or fussiness.
  3. Experiencing night sweats.
  4. Walking slowly or displaying signs of weak bones.
  5. Delayed tooth development.
  6. Frequent hiccups or spitting up milk.
  7. Loss of appetite or poor appetite.
  8. Frequent illnesses or infections.
  9. Height below the average for their age and genetic potential.

In such cases, calcium supplementation should be administered promptly to address the potential calcium deficiency in children.

When children are in the age of development

This is also the golden period when the child’s body develops the strongest, so it needs a large amount of calcium to nourish the bones and joints, helping children to break through both physically and in height. Therefore, parents should not miss this stage to ensure adequate calcium for the body, helping children develop comprehensive height.

The main causes of poor absorption of calcium in the body

Certainly! Here are some reasons why the body may poorly absorb calcium:

Vitamin D deficiency: Vitamin D is essential for calcium absorption in the intestines. Insufficient levels of vitamin D can significantly reduce calcium absorption. This deficiency often occurs in individuals with limited sunlight exposure, naturally dark skin, obesity, or those who consume insufficient vitamin D-rich foods.

Diseases: Various diseases can disrupt calcium absorption and lead to decreased levels of calcium in the body. Kidney and digestive tract diseases can affect calcium absorption, as well as conditions like celiac disease, colitis, pancreatitis, Crohn’s disease, and others.

Consumption of foods high in phytic acid and oxalic acid: Whole grains and beans contain phytic acid, while vegetables like cabbage, chives, spinach, and beets contain oxalic acid. These acids combine with calcium ions to form insoluble calcium salts, hindering calcium absorption. It is important to note that the effect of phytic acid and oxalic acid on calcium absorption is more pronounced when consumed with milk.

Excessive salt intake: The American Institute of Medicine recommends a daily salt intake of about 1,500 mg. Consuming excessive amounts of salt can lead to high blood pressure and promote the excretion of minerals, including calcium, through the urinary tract. This gradual loss of calcium from the body can result in calcium deficiency.

These factors contribute to poor calcium absorption in the body, emphasizing the importance of addressing them to maintain adequate calcium levels..

Diet combined with Calcium helps to develop better height

In order to increase the absorption of calcium, the following combination nutrients should be ensured in the diet:

Vitamin D

This is an extremely necessary nutrient for the synthesis of protein (osteocalcin) that has the function of “transporting” calcium to the bones, helping to absorb calcium from the intestines into the blood, replenishing the bones, helping the bone system to develop healthy.

We can supplement vitamin D through chicken breastbone, fish oil, animal liver… However, to ensure an abundant amount of calcium, it is best to “enjoy” this source of nutrients from the sun before 8 o’clock. morning and after 4pm.

Vitamin C

Some citrus fruits such as oranges, tangerines, grapefruits, and lemons contain a lot of vitamin C, which also contributes to the elimination of toxins from the body, strengthens the immune system, helps calcium be better absorbed into the bones and protects the bones. strong and supple bones that we should not ignore.


Zinc is a micro-mineral that plays an important role especially in the development of children’s height, muscles, nervous system, and immune system. This substance participates in most metabolic processes, cell development, if zinc deficiency the body will slow down growth.

On the contrary, if you combine zinc with a full range of other nutrients, typically calcium, it will be a premise for the body to grow healthy and grow well in height.

Magnesium (Mg)

In the body, about 60% of magnesium is located in bones, this substance plays a fundamental role in creating and implementing bone mineralization process, protects cartilage production well, and has the ability to convert vitamin D into an active form. Therefore, it will enhance the absorption of Calcium into the body, maintain healthy bones and develop well.

You can supplement magnesium content through foods such as almonds, sunflower seeds, chestnuts, pumpkin seeds, peanuts, tuna …

In addition to the above combined nutrients, in the diet, to avoid calcium being unaffected during absorption into the body, you also need to note a few things:

Should cut caffeine: Because if too much of this substance can increase the rate of calcium excretion, weakening the bone system.

Do not eat too salty to avoid increasing the excretion of calcium through the urine.

Limit the use of alcohol, beer, carbonated soft drinks, because these substances are also “enemies” that both make it difficult for the body to absorb Calcium and cause bone erosion, making it difficult to grow optimally.

Limit the use of typical oxalate-rich foods such as rhubarb, beets. Because this will also increase the risk of intestinal calcium excretion from the body through the urinary tract. If the amount of oxalate is too high, it can concentrate in the urine, leading to the risk of stone formation.

In addition to the problems of appropriate calcium supplementation through nutrition, do not forget to combine it with a reasonable exercise and rest regime to improve your ability to improve your physique as desired.

Should children take calcium or not?

Calcium deficiency is one of the causes of short stature and growth retardation in children. However, giving children calcium needs to consult a doctor, do not arbitrarily add calcium to children because an excess of calcium can cause children to become constipated, kidney failure, kidney stones, reduce iron absorption, zinc, magnesium…

Should children take calcium before or after eating?

Supplement calcium for children before or after meals to bring the best effect? One thing mothers should note is that calcium should not be given to children on an empty stomach because this can be harmful to the child’s kidneys, stomach, and urinary tract.

So when giving children calcium, please give them to children from 7-8 am, after they have had a full breakfast to support their best development.

Does excess calcium supplementation affect height or not?

Excessive intake of calcium can have detrimental effects on health. When the body receives an excessive amount of calcium, high levels of calcium in the blood can be deposited in the bones, leading to premature bone hardening and restricted bone growth.

This early ossification of bones can cause stunted growth in children, resulting in shorter stature compared to their peers. Premature bone aging also increases the risk of various bone disorders in children, including scoliosis, kyphosis (hunchback), pectus excavatum (flat chest), and bowed legs.

Excess calcium forces the kidneys to work continuously to increase the excretion of calcium through urine. Prolonged excessive calcium levels can lead to conditions such as ureteral stones and kidney stones.

Furthermore, an excessive amount of calcium can interfere with the absorption of other vital micronutrients, particularly iron, zinc, magnesium, and phosphorus, leading to malnutrition or diseases in children. Excess calcium can also contribute to digestive disorders, loss of appetite, abdominal pain, and frequent constipation.

Fatigue, dizziness, nausea, thirst, and frequent urination are common signs of calcium excess. However, to obtain accurate results, appropriate tests should be conducted to measure the child’s blood calcium levels. At that point, doctors can take the necessary measures and interventions.

It is crucial to maintain a balanced calcium intake that meets the child’s needs without exceeding the recommended limits to ensure optimal health and development.
