Doctor's answer (1)
Dr. Wang Lei
For children's calcium supplementation, choosing vitamin D3 is more effective. When supplementing calcium, it is essential to select a calcium preparation containing vitamin D3, as this helps enhance calcium absorption. Additionally, daily exposure to sunlight also promotes calcium absorption. Furthermore, vitamin D3 can be obtained from animal-based foods such as liver, and particularly from fish liver oil derived from dried seafood, which is one of the richest sources.
