Question

If i am brest feeding and take something with phenylalanine will affect the baby ?

Answer 1

"Aspartame is not detectable in breastmilk after maternal ingestion because it is rapidly broken down in the mother's body. An extremely large intake of aspartame (equivalent to 17 cans of soda or 100 packets of Equal Sweetener) can slightly increase the amount of phenylalanine in breastmilk. Phenylalanine concentrations in milk return to baseline by 12 hours after a large single dose of aspartame. Although it is prudent to avoid the use of aspartame in women who are nursing an infant with phenylketonuria, amounts that are typically ingested in aspartame-sweetened foods and beverages do not result in any additional risk to breastfed infants with phenylketonuria."

Answer 2

What I basically see is that the risks aren't known, so would be best to avoid it.
