Important Notes When Supplementing Calcium for Children

Calcium is an essential mineral that helps build strong bones and teeth. In children, bone development happens rapidly, which means their calcium needs are especially high. A calcium deficiency may lead to:

• Rickets
• Stunted growth
• Sleep disturbances
• Muscle cramps or limb tremors
• Delayed or decayed teeth

Additionally, calcium supports the nervous system, muscles, and cardiovascular functions. Therefore, proper calcium supplementation helps children develop both physically and mentally.

1. Daily Calcium Needs by Age Group

According to recommendations from the Vietnam National Institute of Nutrition, daily calcium needs for children vary by developmental stage:

Meeting these requirements through a balanced diet is essential to prevent calcium deficiency or excess.

2. Signs of Calcium Deficiency in Children

Here are some common symptoms that may indicate calcium deficiency in children:

• Frequent crying or restless sleep
• Night sweats, especially during sleep
• Hair loss forming a bald ring on the scalp
• Slow or decaying teeth
• Soft bones, bow legs
• Delayed walking or standing

If your child shows these signs, consult a doctor for appropriate calcium supplementation advice.

3. Natural Food Sources Rich in Calcium

When possible, calcium should be sourced from natural foods, which are easier for the body to absorb and generally safer. Consider adding these calcium-rich foods to your child’s daily diet:

• Dairy products: fresh milk, yogurt, cheese
• Dark green vegetables: spinach, bok choy, amaranth, water spinach
• Protein-rich seafood: shrimp, crab, small fish (eaten with bones like anchovies)
• Nuts and legumes: almonds, soybeans, mung beans
• Eggs and animal liver

In addition, sun exposure before 9 a.m. helps the body produce vitamin D, which enhances calcium absorption.

4. Should You Use Calcium Supplements?

In cases where the diet doesn’t provide enough calcium—or if your child has increased needs (such as during puberty, or with rickets or poor absorption)—parents may consider calcium supplements.

However, supplementation should follow these principles:

• Always consult a doctor before starting
• Choose reputable brands with clear origins
• Opt for organic calcium forms (like calcium lactate or citrate) for better absorption
• Combine with Vitamin D3 and MK7 to maximize effectiveness

Note: Excess calcium can also be harmful, potentially leading to kidney stones, constipation, and reduced zinc and iron absorption.

5. Key Guidelines When Supplementing Calcium for Kids

• Avoid self-prescribing: Do not give children calcium supplements without medical advice.
• Ensure a balanced diet: Include calcium along with Vitamin D, zinc, magnesium, and phosphorus for optimal bone development.
• Do not take calcium with iron: These two minerals compete for absorption. Space doses at least 2 hours apart.
• Encourage outdoor activity: Sunlight not only keeps kids active but also aids calcium absorption.
• Don't overuse milk: Too much milk and not enough fiber can lead to constipation and nutritional imbalances.

6. Conclusion

Proper calcium supplementation plays a vital role in promoting children’s health and height development. Parents should closely monitor their child’s diet, daily routines, and physical signs to make timely adjustments. Remember: calcium supplementation should always be balanced, scientific, and tailored to each age group’s specific needs.
