What should be done if children lack calcium?

Patient's question:

No

Doctor's answer:

Most cases of calcium deficiency in children are caused by a lack of vitamin D, as calcium absorption requires the help of vitamin D. However, the intake of vitamin D from food is very limited, and sunlight is the primary source of vitamin D. Children today rarely spend time outdoors, so they have less exposure to sunlight.
It is recommended to supplement your child with fish oil from birth and to ensure they take it every day. Additionally, on sunny days, take your child out for more activities. You can also make noodles with bone broth, and ingredients like fish and shrimp shells are high in calcium.
