How long after birth can a baby start taking fish liver oil?

Generally, babies can start taking cod liver oil after birth.

Cod liver oil is a type of fatty oil extracted from the livers of deep-sea fish and primarily contains vitamin A and vitamin D. Vitamin A helps maintain the integrity of mucosal epithelium, regulates and stabilizes immune system function, and promotes growth and development. Clinically, it is used to prevent night blindness and improve vision. In addition, vitamin D promotes cell proliferation and differentiation, helps prevent rickets in newborns, supports bone development, enhances immunity, and facilitates calcium and phosphorus absorption. After birth, babies undergo rapid physical development and are prone to deficiencies in various vitamins or nutrients, which may affect their growth and health. Therefore, babies often need timely supplementation of cod liver oil under medical guidance after birth.

When giving cod liver oil to infants, parents should strictly follow medical advice to ensure regular and appropriate dosing, avoiding overdose that could lead to toxicity. Parents should also closely monitor the baby's mental state and bowel movements, and seek medical attention promptly if any abnormalities occur.
