Question
My son is 4 years old and has several hairless circles on the back of his head. Which type of calcium supplement should I buy? What has been the past treatment and its effectiveness?
Answer
Hello, if you need to supplement calcium, you can choose a calcium supplement that contains vitamin D, as this aids in the absorption of calcium. At 4 years old, it’s also important to pay attention to his diet, ensuring diversity and increasing the intake of calcium-rich foods such as milk, seaweed, shrimp shells, soy products, and animal bones. Additionally, increase outdoor activities and sun exposure, as ultraviolet light helps the body produce vitamin D naturally, which promotes the absorption of calcium from food in the intestines.
