The most basic thing to choose vitamin AD is to choose accurate products specialized in traditional Chinese medicine. Second, look at the formula. Ordinary vitamin ad is a formula of vegetable oil (peanut oil, soybean oil), which has fishy smell, which is difficult for children to accept. It may cause allergic reactions to babies with allergic constitution, and peanut oil contains cholesterol, which will also have a certain burden on the baby's liver. You can choose olive oil-based AD, which the baby likes very much and has a faint fragrance. It is the same pharmaceutical factory as Jinxingbei. The formula of virgin olive oil is close to breast milk, which will not stimulate children's stomach and is easier to absorb. I've been eating it for a while, and now my baby has good immunity. She seldom gets sick and catches a cold, and she is very energetic every day? .
