Patient's question:
The baby needs to digest vitamin D starting from two weeks of age. Does taking fish oil also digest vitamin A and vitamin D? What is the daily dosage limit for vitamin A and vitamin D? (I see some say that vitamin D should not exceed 400 units, but the AD soft gel capsules I bought state that each capsule contains 500 units of vitamin D, and that infants under one year old should take one capsule daily, which makes me hesitant to give her the full dose each time.)Doctor's answer:
Two weeks after the newborn is born, they can digest vitamin AD. Taking fish oil can help digest vitamin AD. It is recommended to use vitamin AD drops, one drop per day (each capsule contains 500 IU of vitamin D). The daily intake of vitamin A should not exceed 1,500 international units, and the intake of vitamin D must be strictly controlled between 400-600 IU, which is relatively safe. It is advisable to take the baby outdoors more often for activities and expose them to sunlight. After four months, the baby can also be supplemented with calcium through food. In this way, the baby will never be deficient in calcium.
