Calcium whey can be taken by infants 6 months of age and older; calcium carbonate is a gastrointestinal irritant and is not recommended for oral administration to infants.
Calcium is adequate for infants who are exclusively breastfed, especially those under 6 months of age, and vitamin D supplementation should only be started about 2 weeks after birth.
Most of the whey calcium is suitable for infants over 6 months of age. It is not recommended for infants under 6 months of age with underdeveloped gastrointestinal function.
Calcium carbonate can inhibit gastric acid when digested in the stomach, and milk alkaloid syndrome can also occur with milk, so it is not recommended for infants.
Most infants can improve the symptoms of calcium deficiency by simply supplementing vitamin D. If necessary, go to the hospital and take calcium supplements under the guidance of a doctor.
