Is Daily Calcium Citrate Safe for Kids? Long-Term Effects on Growth

Can calcium citrate be taken daily?

Hello, my son is in the second grade, and he really enjoys the powdered calcium citrate sold at Costco.
He consumes one packet daily as recommended on the packaging for children.
Can children consume this product long-term? Will it have any impact on his growth? Thank you!

Hello Mr.
Lin! Calcium is an essential nutrient for growth, and calcium citrate has a higher absorption rate, making it a suitable supplement.
However, for children's growth, it is also important to increase caloric intake, protein, vitamins, and other minerals.
According to the recommendations from the Ministry of Health and Welfare, the suggested daily intake of calcium for children aged 7-9 years is 800 milligrams.
One cup of milk provides about 240 milligrams, so consuming two cups of milk a day, along with foods like cheese, black sesame, and tofu, can help meet the daily calcium requirement while also providing additional nutrients.
It is advisable to supplement nutrients with natural ingredients, as a balanced intake not only provides essential nutrients but also includes a variety of nutrients.
Wishing you peace and health.

More Info

Calcium is an essential nutrient for children, particularly during their growth years, as it plays a crucial role in the development of strong bones and teeth. Calcium citrate, a form of calcium that is often recommended for supplementation, is known for its high bioavailability, meaning it is easily absorbed by the body. This makes it a popular choice for those who may not get enough calcium from dietary sources alone.

For children, the recommended daily intake of calcium varies by age. According to guidelines, children aged 7-9 years should aim for about 800 mg of calcium per day. This can typically be achieved through a balanced diet that includes dairy products, leafy greens, nuts, and fortified foods. For instance, one cup of milk provides approximately 240 mg of calcium, so consuming two cups of milk along with other calcium-rich foods can help meet daily requirements.

Regarding the use of calcium citrate supplements, it is generally safe for children to take them as long as they are used appropriately and within recommended dosages. The packaging of the product your son is consuming likely provides guidance on the appropriate amount for children, which should be followed closely. However, it is essential to ensure that the total calcium intake from both food and supplements does not exceed the upper limit, which is set at 2,500 mg for children aged 9-18 years. Excessive calcium intake can lead to hypercalcemia (high blood calcium levels), which may cause various health issues, including kidney stones and impaired absorption of other essential minerals.

Long-term use of calcium citrate in moderation is unlikely to have adverse effects on growth. In fact, adequate calcium intake is crucial for optimal bone density and overall growth during childhood. However, it is important to balance calcium supplementation with other nutrients that support bone health, such as vitamin D, magnesium, and phosphorus. Vitamin D, in particular, enhances calcium absorption and is vital for bone health.

While calcium citrate can be beneficial, it is advisable to prioritize obtaining nutrients from whole foods whenever possible. Natural food sources not only provide calcium but also offer a variety of other essential nutrients that contribute to overall health. Foods rich in calcium include dairy products (milk, cheese, yogurt), fortified plant-based milk, tofu, leafy greens (kale, broccoli), fish with bones (sardines, salmon), and nuts (almonds, sesame seeds).

In conclusion, calcium citrate can be a safe and effective supplement for children when used appropriately. It is essential to monitor total calcium intake from both dietary sources and supplements to avoid excessive consumption. Additionally, fostering a balanced diet that includes a variety of nutrient-rich foods will support your child's growth and development more comprehensively. If you have any concerns or specific questions about your child's calcium intake or overall nutrition, it is always best to consult with a healthcare professional or a registered dietitian for personalized advice.
