Question

Parents of formula-fed male infants have questions about the necessity and appropriate dosage of calcium and cod liver oil supplementation, and are concerned about the potential health risks of over-supplementation.

Answer

Experts suggest that formula-fed infants usually obtain sufficient calcium and Vitamin D from breast milk or formula, so additional supplementation is not necessary. Over-supplementation of calcium may have adverse effects on the growth and development of infants. It is recommended to choose well-known brand formulas and ensure the infants get adequate sunlight exposure to promote the generation of Vitamin D and absorption of calcium.
