Dr. Xie Huimin reply Nutrition


Acidified milk powder is produced by adding citric acid to milk powder.
It is claimed to lower the intestinal pH, aiding in digestion and absorption.
Currently, it is commonly used for infants experiencing diarrhea and bloating.
However, it may not have the same effect on every infant.
If you need to use it, please consult a physician.

More Info


Acidified infant formula is a specialized type of infant formula that has been modified to have a lower pH level, making it more acidic than standard formulas. This modification is primarily aimed at mimicking the natural acidity of breast milk, which can help in the digestion and absorption of nutrients. The acidity can also inhibit the growth of certain harmful bacteria in the gastrointestinal tract, potentially reducing the risk of gastrointestinal infections.

The need for acidified infant formula typically arises in specific situations. For instance, infants who experience gastrointestinal discomfort, such as colic or reflux, may benefit from this type of formula. The acidity can help to reduce the frequency and severity of these symptoms by promoting a more favorable environment for digestion. Additionally, infants who are prone to constipation may find relief, as the formula can help to soften stools and promote regular bowel movements.

It is important to note that not all infants require acidified formula. Most healthy infants thrive on standard infant formulas or breast milk, which provide adequate nutrition without the need for acidification. However, for those who exhibit signs of digestive distress or have been diagnosed with specific gastrointestinal conditions, an acidified formula may be recommended by a pediatrician or a healthcare professional.

When considering whether to switch to an acidified infant formula, parents should consult with a healthcare provider. This is crucial because the nutritional needs of infants can vary significantly based on their age, health status, and individual circumstances. A healthcare provider can assess the infant's specific needs and determine whether an acidified formula is appropriate.

In terms of long-term use, while acidified formulas can be beneficial for certain infants, they should not be used indefinitely without medical supervision. As infants grow and their digestive systems mature, their nutritional needs may change. Typically, by the time an infant reaches six months of age, they should begin transitioning to solid foods, and the reliance on formula—whether standard or acidified—should decrease.
For infants who are currently using an acidified formula and are doing well, it is generally safe to continue until they reach the appropriate age for introducing solid foods, usually around six months. After this point, parents can consider transitioning to a second-stage formula or a standard formula, depending on the infant's dietary needs and any recommendations from their healthcare provider.

In conclusion, acidified infant formula can be a valuable option for certain infants experiencing digestive issues. However, it is essential to consult with a healthcare professional before making any changes to an infant's diet. Regular monitoring of the infant's growth and development is also crucial to ensure that their nutritional needs are being met effectively.
